Revealed: A Simply Unique Technique to Stop Impulse Buying that Credit Card Companies Never Want You to Know
The PANEL Test
Because Money Matters The 8 Principles to Build Your Wealth

My 16-year-old daughter has been using this PANEL test that I taught her every time she's tempted to spend money. This test saves her money while helping her become responsible and sensible. You can use it too to help you make better choices and prevent impulsive purchases:
P = Positive
A = Affordable
N = Now
E = Essential
L = Long-term
Imagine you have a panel of personal advisors who would ask you these questions every single time you are about to make a purchase:
 - Does it have a POSITIVE value?
 - Can you AFFORD it?
 - Do you need it NOW?
 - Is it ESSENTIAL?
 - Does it provide LONG-TERM value?
Or the questions can be summarized as: Is this an essential purchase with long-term positive value that you need now and can afford?
Pay attention to the underlined words. You'd want to ensure that what you are about to buy is essential that satisfies your need, not want, and the timing is now and not later. If you can wait, you will have a chance to delay the purchase and put it through the PANEL test again.
The purchase has to bring positive value to your life for a long term, not just a temporary thrill. Value is not only determined by the price of the product or service, but also measured in terms of happiness, health and personal improvement. It could be about preventing or solving a problem too. Consider how this purchase will affect your overall financial situation.
Affordability means that you can pay for the purchase with your cash not already designated for something else. If you have to use your education fund to pay for a car, you can't afford the purchase. You should also consider associated costs, time commitment, and lifestyle changes. Look beyond the price tag— many things have hidden or unexpected costs. My mother often points out that buying a new shirt may lead to buying a new pair of pants, a new pair of shoes to match, and so on. If your purchase requires maintenance, know what the expected cost is (including storage rental if needed), how much time and energy it requires and how it affects you and others. For example, if you were to get a pet, there will be ongoing costs and time needed to care for it. Will you have time left to enjoy the companionship and be able to provide the affection your pet needs?
Remember too, that the cost is much higher than the sticker price when you buy with credit and don't pay in full on time. If you make a minimum payment of $60 per month on your credit card balance of $3,000 at 20% interest rate, it will take you over 9 years to pay it off and the total of all payments will be around $6,500. So a $3,000 home theater system or wedding dress actually costs $6,500! You can use this calculator that compares three different payment options to pay off your credit card balance. Also, as long as you are still paying for an item, it isn't really yours.
If you live in a place where buying on credit is socially acceptable and encouraged, be sure your spending behaviour does not get you locked into a chain of debt misery.
Credit cards are useful if you know how to use them to your advantage and don't treat them as your unlimited source of money. Credit cards provide security, convenience, and benefits. They are often the best (or only) payment option for certain transactions, such as car rental or vacation booking. If the card has no annual fee and you pay the balance in full within the grace period, you earn the free use of the money while building up your credit and you enjoy the benefits your card offers, such as reward points and cash back.
Credit card companies may also provide extra protection when something goes wrong with a product or service paid for with your credit card. For example, for a faulty product, you can file a claim directly with the credit card company when the supplier has gone out of business or has no money to reimburse you.
Debt trouble begins when a person underestimates his/her spending and overestimates his/her ability to pay back. It is the ease of whipping out a piece of plastic to exchange for something tangible that gets many people into heavy debts. Credit-card spending doesn't feel like real money and only when the statement comes do we realize how quickly purchases add up. Many of us don't account for the long-term costs of interest and fees despite plenty of information, advice and even legislation attempting to warn us. Do you know exactly how much you pay in a year for fees, interest and other charges for using your credit card? If you knew you'd end up paying an extra $200 for a $500 product, would you still want to buy it?
Credit companies are in the business to make money. From their side, the longer and higher debt you carry, the more money they will make. Credit companies thrive on minimum payments and they make it easy for you to see that on your statement. The simple rule is: Don't use your credit card unless you have the cash to pay the balance when the statement is due.
It is often easier to buy than sell. Don't buy something assuming you can sell it if you change your mind. Your brand new $20,000 car will lose at least $5,000 in value the minute you drive off the dealership's driveway.
You can download the PANEL test card here. Print a copy, put it close to your credit cards, and use it as a good reminder every time you are about to make a purchase.
The PANEL test has many possible combinations. If any of your answers is "No", ask yourself the following self-reflecting questions to get insights into you and your spending habits. Be honest with yourself and talk to someone or seek help when you need it.
If the purchase has no POSITIVE value:
 - Why do I want it?
 - Am I being influenced by something or someone?
 - Is there something else I can do or get instead?
 - What could be the worst thing if I go through with this?
If you can't AFFORD the purchase:
 - Have I considered other options?
 - Can I negotiate more effectively?
 - Am I living based on my standards?
 - Is this worth going into debt for?
If you don't need the purchase NOW:
 - Am I being impulsive?
 - Am I feeling depressed?
 - Am I feeling pressured?
 - Am I feeling entitled?
If the purchase is not ESSENTIAL:
 - Am I wanting too much?
 - Am I trying to get validation or approval?
 - Am I trying to impress or please someone?
 - Am I competing with someone?
If the purchase does not provide LONG-TERM value:
 - Am I a trend chaser?
 - Am I after instant gratification?
 - Am I being impractical?
 - Am I being wasteful?
Even if you answer "Yes" to all the questions, think about whether it is a smart buy, for example, can you buy it cheaper at a different time or place? If the purchase you want to make fails the PANEL test, it is likely a fleeting desire and it is sensible for you to walk away from it, especially when the cost is high. If you are in doubt, it's better not to buy unless it's a rare item that can't be easily purchased elsewhere. Ultimately, you are the decision maker on how to spend your money. The thought process does not completely stop you from making purchases you might later regret, but it helps you become more conscious of your spending habits, which will result in fewer slips. We all experience weak moments. Lifestyle changes come only with patience, tenacity, and practice.
If you have a family, share your dreams and plans with your loved ones so you all can work together towards them. Ask for help and encouragement from people you love. Tell them you're trying to trim your spending and you want their suggestions and support.

'Trial by Google' the new threat to privacy, Leveson warns
Trial by media? Trial by Google is the real threat to privacy, Lord Justice Brian Leveson told a Sydney audience today -- fresh from delivering his media ethics report to the UK government.
"There is not only a danger of trial by Twitter, but also of an unending punishment, and no prospect of rehabilitation, via Google," warned Lord Justice Brian Leveson in Sydney this morning.
"Instances of naming and shaming are relatively commonplace. It takes but a minute to record someone doing something in a public place and to upload it up to the internet. Once on the internet the episode, the behaviour, is there for the world to see and is there permanently at the click of a mouse."
The resulting harm can be "both permanent and disproportionate".
"Children and the young do not appreciate that uploading a compromising photograph for a laugh can have consequences for the long term future because once the photograph is in the public domain, it can be found, copied and reproduced," he said.
Leveson was giving the keynote address to today's "Privacy in the 21st Century" symposium, organised by the Communications Law Centre at the University of Technology Sydney. He set his warning in an historical context.
The gossip-filled "penny press" of 1830s England, the tabloids of their day, were wildly popular and seen as a threat to members of society. So were the emerging technologies such as the telephone, the wiretap and photography. But in time the excesses of the new media operations were reined in by new laws and new social norms.
"In many ways we've been here before," Leveson said. But he also also saw key differences when it came to the internet.
While newspapers and other traditional news media might push the boundaries when it comes to invading privacy, they're generally held in check by commercial pressures as much as the law, said Leveson. Not so for the internet.
"With some exceptions for bloggers who carry advertising and tweeters who are sponsored, online bloggers or tweeters are not subject to the financial incentives which affect the print media, and which would persuade the press not to overstep society's values and ethical standards. Equally, there is a view that blogging or tweeting is publication without responsibility or accountability and that, in this sense, the internet is beyond the reach of the law," he said.
Leveson pointed to the 2011 "super-injunction spring" in England and Wales, when interim injunctions were granted prohibiting the disclosure of both the substantive content of the injunction and the very existence of the injunction itself. Traditional media complied. Bloggers and tweeters didn't.
"Rumour and speculation regarding the number of such injunctions was rife. Twitter in particular and various blogs circulated and discussed names of individuals who were said to have obtained such injunctions. Names of various celebrities swirled around the internet," he said.
"Bloggers rejoice in placing their servers outside the jurisdiction where different laws apply."
But internet users are not actually beyond the reach of the law, Leveson said, citing as examples the prosecution of individuals involved in the UK's autumn 2011 riots, and Twitter users being sued for defamation for wrongly identifying someone as a p-edophile.
"Given that the internet is not entirely out of the law's reach it is likely in time that, as with the media in the 19th century, it will start to have an effect in individuals' behaviour. It will start to modulate behaviour, and curb its wilder excesses. Time and proper application of the law will play the same role for the internet as it has done in all other areas of our lives. It will shape our behaviour and help to reinforce social norms," Leveson said.
"This is not to say that social norms may not change over time. Our view of what is, for instance, private information may change. Our view of privacy may change. I imagine though that individuals will always seek to preserve some degree of privacy and will seek the law's protection to protect it."
Leveson did not comment on his recent report on media ethics to the UK government. "I treat the report as a judgement, and a judgement must speak for itself," he said.
The symposium continues this afternoon.

 And he is correct but will face the fury of many in the media, tech writers, bloggers and such who believe they have the freedom to name, shame or invent conspiracies often citing each other as 'evidence'.
 Witness the McAlpine falsehoods that jumped the shark where mainstream media began to parrot and dip their toes into David Icke's weird conspiracy claims that say the royal family are reptilian devil worshippers running a pedo ring.
 The MSM is floundering to such an extent that today we have press agent arrested in the UK in the Jimmy Savile matter- a man who sold stories about another infamous one arrested in the same matters,to the mainly Murdoch tabloids.
 But bloggers and their media supporters rejoice in corporate entities like Google, Twitter, Facebook and the rest who base themselves off-shore, pay minimal tax and suck the life out of advertising revenues.
 Far from freedom, the advent of the internet and Google with the falsehood that somehow it is free and uncontrolled, hastens fascist style control.
 2. John Bennetts
 What is privacy? Where did it come from? Who has privacy and who has not? What is the social cost of privacy, and what is the social benefit?
 I imagine that out there somewhere, there are well considered books on this subject.
 In trisecretsbal life, privacy is close to zero. Everybody knows everybody else's actions – or soon will, especially if they are antisocial.
 In pre-industrial society, privacy was more or less available to the upper classes but not to the remainder of the population. The lord of the manor had secrets, mistresses: privacy for the few, it could be argued, came at the expense of the many whose circumstances limited privacy to the basics.
 So, is privacy a right or a construct? Wgere does it start and how much privacy is too much? Is privacy a universal right?
 In an increasingly open and communicative world, with millions of public security cameras and digital recognition software, cross-matched files of personal tax, finance, education and social matters, what forms of privacy are essential?
 Last, why is it an invasion of privacy when a royal lass has her upper torso photographed or a prince has his bottom published for all to see but is not an issue when millions of others, similarly disrobed, are photographed by others annually? Did they not disrobe voluntarily?
 Putting modern laws aside, what ethical, moral and philosophical issues are at foot regarding the history and practice of privacy in modern, electronic, Western society?
 Where is the intellectually rigorous book on the subject?
 3. John Bennetts
 trisecretsbal = tribal, sorry. Typo.

 The dream of a "free" internet is finished. It was a liberal geeky dream that had its origins in the vaguely-hippy-communal-freethinking culture of the 60s and 70s. Now "free" has become a Trojan Horse. Advertising and data mining pays for everything. Bloggers are as beholden to their advertisers as old media. More beholden because there's so much more competition for the advertising dollar. Old media had a monopoly on the production and distribution of media. So it had the luxury of separating editorial from advertising. On-line media doesn't have this clout. There are thousands and thousands of blogs recycling the same old rubbish. So much for diversity. Somebody or something has to pay the bills. Journalism, in print and on-line, is at its lowest ebb. We need to start paying for things. We'll only have a free press when we start coughing up some our hard-earned to pay for it.

reminder that changes to EPIRB requirements come into effect on 1 January 2021. AMSA has prepared guidance materials to help industry understand the new float-free EPIRB requirements.
When submitting stability documentation, we encourage surveyors to include detail on the configuration of the vessel at the time the lightship report or practical stability test was undertaken. Many owners are not aware of the requirement to notify AMSA of any changes to the vessel's structure, arrangement, materials or scantlings. Such changes may jeopardise the vessel's stability.
Typical changes are outlined in Marine Order 503 Schedule 1 Clauses 6, 7 and 8 and include:
- Changing engines
- Modifying / adding fishing gear (trawl apparatus, net reels etc.)
- Adding tanks
- Removing ballast
- Modifying the hull or arrangement.
Other common issues include:
- Owners overloading their vessels and exceeding the approved deadweight
- Weight "creep" associated with the accumulation of miscellaneous equipment, stores and hull coatings.
Including a detailed description of the vessel as part of a stability approval provides a baseline against which potentially dangerous modifications can be identified—particularly in the event of capsize. This is especially important with smaller vessels where such changes have a greater effect on stability.
NSCV C6C outlines the format and content of stability documentation (see also Survey Matters December 2019).
The following table is an example of a vessel description AMSA recommends being included in the vessel particulars section of a stability book; in the stability approval letter; or in the stability notice. The intent of the vessel description is to provide a snapshot of the vessel in "as-approved" condition. The amount of information will depend on the complexity of the vessel. Ideally photos of the vessel showing items of interest with regards to stability should be included as an addendum to the stability documentation.

Chapter 2.9 of SAGM Part 2 allows a surveyor to submit their periodic survey recommendations to the National Regulator with an outstanding deficiency in certain circumstances.
Surveyors can recommend a periodic survey "with dispute" when the owner refuses to rectify a deficiency. Chapter 2.9.4 of SAGM Part 2 sets out the requirements for when a surveyor identifies a deficiency which is disputed by the owner.
We have seen some surveys recommended with dispute on new and transitional vessels during review of initial survey applications. In one example, an owner refused to fit structural fire protection to a vessel that triggered the application of NSCV C4 and the relevant clause for structural fire protection to be fitted. However, the requirements for new or transitional vessels cannot be disputed as these standards are clearly laid out in Marine Order 503. If during initial survey an owner refuses to address a particular issue, there are three courses of action available to the surveyor:
- Contact AMSA via DCV Survey and obtain confirmation (or otherwise) that the deficiency must be rectified. A written confirmation can be passed on to the owner.
- Apply for a specific exemption. The applicant will need to detail their reason for needing the exemption. Cost or inconvenience are not sufficient reasons for the National Regulator to issue an exemption. In these cases, the applicant can refer to the AMSA specific exemption policy.
- Submit your report as not recommended and detail the individual non-compliance. This is important as indicating recommended, or recommended with conditions, is stating that the vessel complies with the applicable standards. We can then address the non-compliance with the owner through a request for further information. Where an owner will not address the issue (either through rectification or applying for an exemption) AMSA will decide based on the information provided. This may result in refusal of an application.

text: Tsong kha pa (14th century) is arguably the most important and influential philosopher in Tibetan history. An Ocean of Reasoning is the most extensive and perhaps the deepest extant commentary on Nagarjuna's Mulamadhyamakakarika (Fundamental Wisdom of the Middle Way), and it can be argued that it is impossible to discuss Nagarjuna's work in an informed way without consulting it. It discusses alternative readings of the text and prior commentaries and provides a detailed exegesis, constituting a systematic presentation of Madhyamaka Buddhist philosophy. Despite its central importance, however, of Tsong kha pa's three most important texts, only An Ocean of Reasoning remains untranslated, perhaps because it is both philosophically and linguistically challenging, demanding a rare combination of abilities on the part of a translator. Jay Garfield and Ngawang Samten bring the requisite skills to this difficult task, combining between them expertise in Western and Indian philosophy, and fluency in Tibetan, Sanskrit, and English. The resulting translation of this important text will not only be a landmark contribution to the scholarship of Indian and Tibetan Buddhism, but will serve as a valuable companion volume to Jay Garfield's highly successful translation of The Fundamental Wisdom of the Middle Way.


How to make an egg salad not smell
Eggs can taste delicious if cooked properly to stop the smell.
Jupiterimages/liquidlibrary/Getty Images
An egg salad whether on its own or in a sandwich is easy to make and can taste delicious but the smell can be off-putting. Eggs can produce a sulphuric smell caused by over cooking. These egg proteins can become over coagulated and this creates an excess of hydrogen sulphide, which causes the eggy smell.
Fortunately, there are a few simple steps to prevent this from happening.
Place the eggs in a saucepan of cold water so that they are fully submerged. Add 2 teaspoons of white vinegar and bring the water up to a simmering point. Continue to simmer for 7 minutes. The vinegar will neutralise the odour without affecting the taste of the eggs.
 - Place the eggs in a saucepan of cold water so that they are fully submerged.
Remove the saucepan from the heat and remove the eggs. Submerge the eggs in the bowl of cold water and leave for 2 minutes. The cold water stops eggs from continuing to cook inside their shells and prevents the yolk from turning a dark greyish or green colour. Discoloured yolks are a result of a reaction that increases the sulphur smell.
Peel the eggs to remove the shells. Store the eggs, covered in the fridge until you are ready to make the rest of your salad.
To remove any lingering smells from your kitchen, boil a saucepan of water with 1 teaspoon of vinegar for 5 minutes. Discard the water. The smell of vinegar will disappear quickly.

But ol' man river,
He jes' keeps rollin' along!
Is water male or female – and does it really matter? Unlike languages such as French, Spanish and German, English does not allocate gender to words. Although some things, ships and countries for example, often have feminine associations, there are no grammatical rules to make something either male or female.
Cognitive research has suggested that language and the way people use it has a profound influence on how we see the world. Water, for example, is often more associated with concepts of femininity – the river Ganges (Ganga) is well-known as a feminine sacred symbol of Indian culture in addition to being a central source of survival – but in the famed Hammerstein and Kern song, Ol' Man River, the river Mississippi is portrayed as a man.
The feminine Ganges symbolises faith, hope, culture and sanity – and, since the beginning of time, "she" has been as a source of livelihood for millions of people. By contrast, the endless, uncaring flow of the "old man" Mississippi is seen as a metaphor for the struggles and hardships of the men forced to work on it.
The allocation of a specific gender to an object or feature of our landscape might not be a result of conceptual categorisation and this is supported by an examination of noun classes and "gender shifts" across different grammatical systems. Is a French car (female) different in any way to a Spanish (male) car or is it just a question of grammar without connotation or semantics?

Natural disasters and suicidal behaviours
Read the full review here [Note: not free access – pay per view]
There is a need for further research with solid designs to elucidate the impact of natural disasters on suicidal behaviors. Mental health and suicidal behaviors should be monitored for several years after a disaster.
This systematic review assessed the potential impact of natural disasters on suicidal behaviors by analyzing 42 papers. 19 of these papers analysed suicide mortality and 23 non-fatal suicidal behaviors. The effects of earthquakes have most frequently been studied in relation to suicidal behaviors (n=20), followed by hurricanes (n=11), tsunamis (n=4), floods (n=3), heat waves and drought (n=3), and multiple disasters (n=1). There is a drop in non-fatal suicidal behaviors in the initial post-disaster period. Some studies report a delayed increase in suicidal behaviors. Previous and current mental health problems are factors that could increase the risk of suicidal behaviors after natural disasters. Economic conditions should also be considered as a possible contributing factor.

arcs are another important means for constructing house systems, mainly those which emphasise the time factor, like for example Placidus' system.
Diurnal arcs are those semi-circles which are described by a celestial body moving above the horizon from its ascending point in the East to its descending point in the West. Each point in the sky marks such a diurnal arc. The arc resulting from the movement of the descending point to the next ascending point is called nocturnal arc. Put together, diurnal and nocturnal arcs result in a full circle.
In astrology, only those points are important which are projected onto the ecliptic, usually the planets, Sun and Moon. Astrologically speaking, these are always located on some point of the ecliptic - and this ecliptical point also has a diurnal or nocturnal arc. This means that all points on the ecliptic ascend and descend at some stage.
Placidus used these arcs to construct his house system by saying that a particular point on the ecliptic which has covered half the distance above the horizon has reached the midday (upper) culmination, which is, astrologically speaking, exactly at the point of the Midheaven. This means that this point on the ecliptic corresponds to the Midheaven as one of the four cardinal points. And the point on the ecliptic which begins its diurnal arc in the East, corresponds to the Ascendant. In order to define the intermediate houses, he concluded that the point which has covered one sixth of its daily path from East to West, corresponds to the cusp of the twelfth house, and the point on the ecliptic which has covered two sixths marks the cusp of the eleventh house, etc. (cf. illustration 5).
If this system is complemented by the nocturnal arcs, the house system according to Placidus is deduced from the daily movement of the ecliptic reflected by the diurnal arcs.

XebiaLabs, the recognized leader in enterprise-class DevOps and Continuous Delivery software tools, announced the first predictive risk solution for DevOps that warns teams of delays and risks in the software delivery process.
Using a new DevOps Prediction Engine, the XebiaLabs DevOps Platform's Risk Prediction Module combines machine learning with a proprietary algorithm to give teams a "weather forecast" for their releases before those releases even start to run.
Software releases often plagued by unforeseen release delays and failures
It's hard for DevOps teams to predict factors that will delay releases or cause them to fail—and teams are often surprised by failures after release processes have already started, leaving them scrambling to roll back changes and resolve errors.
DevOps prediction engine shines light on release problems before they happen
The XebiaLabs DevOps Prediction Engine highlights potential bottlenecks before release processes start, so Release Managers, Developers, and DevOps Engineers can take preventative action, adjust timelines, and keep the business in the loop. Powerful predictive risk analysis enables DevOps teams to answer questions such as:
- What are the chances this release will fail, and what can we do about it?
- Is this release likely to be delayed, and by how long?
- How likely is a team member to skip specific release tasks, and why?
- What caused releases like this one to fail or be delayed in the past?
Predictive risk analysis prevents a release disaster
XebiaLabs already provides customizable risk scoring that identifies warning signs during a release process to indicate when it is not on track. Now, the company has added a new Risk Forecast Function to the XebiaLabs DevOps Platform. Powered by a machine learning-based DevOps Prediction Engine, it offers the following capabilities:
- Risk alerts that warn the team when a release is likely to be delayed or to fail, before the release pipeline starts running, so they can take preventative action
- A comprehensive Risk Forecast view that summarizes predicted delays and failures for every task in the release process, so teams can drill down into the specific parts of the process that are likely to cause issues
- An overview of statistics for similar releases, so teams can see historical analysis at a glance and identify trends in both release and task failure, across all tools in their release pipeline
- Release forensics that uncover flaky automated tests, problematic build setups, long-running deployments, and time-consuming manual tasks, so teams can identify their biggest pain points and make the changes that will have the most impact on their ability to deliver software quickly and reliably
"The XebiaLabs DevOps Platform has long included advanced features for enabling organizations to reduce the potential for risk failure," said Andreas Prins, Vice President of Product Strategy for XebiaLabs. "The XebiaLabs Predictive DevOps Engine is another huge step forward towards increasing IT teams' ability to move away from reactive management of their releases, to a proactive approach that preempts failure and optimizes their pipelines for success."

If a table happens to have a timestamp column that is set on every insert or update of a row, the incremental replication methods can be used. This simply uses that column to track where in the replication process it left off each time it is run. There's one for insert-only tables and another that can handle if that column is also set on every row update. While the insert-only one requires no primary/unique key, the updater one does. This method does not replicate any row deletions.
This means that, just like the snapshot method, only select privileges and no triggers are required on the source table. This method is ideal for insert-only, high-transaction tables such as one tracking hits on a website. Adding a trigger to track the changes to such a table for replication could place a lot of extra load of your front-end production systems.
Since this method was introduced in our environment, we've had to deal with several edge cases. One of the first was when the rows were just grabbed by getting everything larger than the last recorded timestamp. This runs into issues when the source table hasn't stopped inserting rows for its latest timestamp value. Since that value is used for the next batch's lower boundary and it thinks it has all rows matching that timestamp, it may miss some the next batch. So a boundary interval was introduced. This sets the batch's upper limit to be less than a given interval. For example, say the last recorded timestamp on the destination was 2013-02-18 12:30:00 and mimeo runs the same day at 13:30:00. With a 10 minute upper boundary (mimeo's default), this would get all rows with values > 2013-02-18 12:30:00 and < 2013-02-18 13:20:00. If rows are constantly being inserted, this does mean the destination is always 10 minutes behind. But it also ensures that no rows are ever missed. The boundary interval is required to enforce data integrity, but it is also configurable on a per table basis.
Another issue along the same lines has to do with when a limit is set on how many rows are pulled each batch. If the maximum number of rows in a batch is pulled, the upper boundary could be cut off in the middle of any timestamp value, not just the latest values being inserted. This is handled by always removing the highest value from the batch when the maximum number is pulled, delaying it to being pulled the next run. Bigger issues occur when the batch contains timestamp values that are all the same. There is no way to ensure a consistent pull of data from the source in this case. So if this issue is encountered, mimeo just cancels that batch entirely. To fix it, you must either remove the batch limit or set it to a high enough value that it can pull data with at least two different timestamp values. The internal logging & monitoring system (pg_jobmon) sets off a critical alert if this occurs so you will know if it happens. Before v0.10.0 a batch limit was always used, so this was a bigger concern then. Since that version, they are no longer turned on by default, but I left the option available. So if you use that option, just be aware of these limitations.
And lastly, probably be biggest cause of issues with time-based replication is daylight savings. When time changes, you chance losing data on your destination table, especially when setting the clock back since it thinks it already got that data. Now is a good time to mention that if you can run your databases on a system that uses UTC/GMT time, you can make a lot of time-based issues with storing data go away. But if that's not possible, and you want to use this replication method, there are some configuration options available. When you set up incremental replication using mimeo's maker functions, it checks to see what timezone the database is running in. If you're in UTC/GMT, you've got nothing to worry about. If you're not, mimeo sets a flag to turn off replication around the time change. I haven't found any better (ie, less outrageously complex) solutions to this other than just completely stopping replication for that time period. By default it turns off replication between 12:30am and 02:30am. If you need to narrow down or change that time period, the start & end times are configurable.
So at first, basing replication on a timestamp seems like it wouldn't be too complex an issue. But as always, things are never as simple as they may seem to be.

Scientists trying to figure out how cheetahs manage to run faster than any other mammal might have a few tips to pass along to human runners, reports the New York Times' Well blog. For one thing, build up those thighs. The cheetah has powerful upper legs, which allow them to pump faster than, say, a greyhounds' legs. (The two animals were compared in the experiment because they're similar in build, but wild cheetahs top out at 65mph and the dogs at 40mph. The fastest humans clock in around 28mph.)
Humans also might want to try light running shoes because "having less weight in the lower portion of the leg aids in swift repositioning," says the lead researcher. That's probably not mind-boggling advice for two-legged sprinters, but maybe the most interesting part of the experiment was about the big cats themselves. Scientists timed cheetahs from zoos and found that they reach speeds of about 40mph. It's only their wild brethren, maybe more used to galloping after dinner, that can hit 65mph.

There are many variations of balance toys—all of them interesting and a bit counterintuitive. In some of my technology classes I've shown my students how to weld "cut" nails together to make a balancing person. However, welding tanks are not available to most people. Fortunately, Australian educator Katrina shows how to make a design that anybody can make. Sometimes it takes a fresh view to cut through all the complexity and simplify the construction enough that elementary school kids can build. Thanks Katrina!
The trick to making it balance mysteriously is to keep the center of gravity low by making sure more than half the weight below the feet. She accomplishes this with a lightweight foam head and denser modeling clay weights.

This study was designed to provide important new information about relapse prevention in Indigenous 1 people with chronic mental illness. It aimed to explore Indigenous mental health promotion with Aboriginal mental health workers (AMHW) in order to develop strategies for effective mental health intervention. The research was conducted in three remote Indigenous communities in the top end of the Northern Territory with AMHW. Assessment, psycho-education, and care-planning resources were developed with local AMHW through exploration of local Indigenous perspectives of mental health promotion. Qualitative research methods and an ethnographic approach were used to elicit information, and data included key informant interviews, participant observation, music, photography and story telling. The study confirms that Indigenous people in remote communities prefer to use story telling and local language, local artwork and local music to convey health information. It also confirms that family and local practitioners are key cultural informants and that indirect, holistic and 'two-way' messages are preferred.

Interview with Philippi Sports Nutrition
1) What is the history of Philippi Sports Nutrition?
2) How do you design supplements, specifically, how do you determine ingredients?
Each supplement we create is designed for a specific reason. All our ingredients are selected and used in the amounts that are proven effective in clinical studies and at the Philippi Sports Institute. Our pre-workout Power Shot drink is designed to create cellular energy, buffer lactic acid and allow more nutriments to be pumped to the muscle. This provides endurance, strength, and allows more nutrition to be delivered to the muscle.
3) Why is it important to choose a supplement based on the phases of the workout?
Nutriment timing is very important in sports nutrition. Taking Power Shot pre-workout creates endurance and strength for the workout. Recovery Shot is a performance regenerator designed to bring BCAA (Branched-Chain Amino Acids), electrolytes, and hydrating opticarbs into the body after the workout to start the recovery process. Training Armor is specifically designed to lower cortisol levels, decrease the degeneration and absorption of ammonia and promote immune system recovery. We use antigen infused extract 10, better known as Ai/E10, arabinogalactan, astragalus root and maitake mushroom.
4) How do supplements help avoid injuries?
When the body performs intense training, weightlifting or specific sport performance, many reactions occur in the body besides tissues breakdown in the muscles involved. Inflammation takes place on many different levels; in the immune system, in ligaments and tendons, in the hypothalamus, pituitary and adrenals, and in the central nervous system. For total recovery to take place, all of these areas have to be assisted through proper diet and/or specific supplementation. If recovery does not take place, over time exercise-induced stress can lead to a multitude of problems including: ligament and tendon injuries, immune system suppression and sickness or infection, reduced testosterone levels, and muscle tissue breakdown.
5) How do supplements help recover from injuries?
Supplements aid in helping the body's soft tissue, connective tissue, nervous system and immune system recover from both injury and exercise-induced stress by supplying specific nutriments to the muscle and connective tissues. Injuries occur on a lot of different levels; not only muscles, ligaments and tendons, but also the suppressed immune system. Another is the inflammation that takes place due to exercise-induced stress. They all must be addressed nutritionally in order for recovery to take place.

Symantec detects ransomware variants created directly on mobile devices
Symantec has discovered new variants of Android.Lockscreen (ransomware) that are using pseudorandom passcodes to prevent victims from unlocking devices without paying the ransom.
In a recent blog post, Dinesh Venkatesan a principal analyst at Symantec, highlighted the fact that previous versions of these threats locked the screen and used a hardcoded passcode.
However, Symantec analysts have been able to reverse engineer the code to provide victims a way to unlock their devices.
Venkatesan also says the attackers have combined a custom lockscreen with the device's lockscreen to create an additional hurdle for those infected.
"Symantec has seen several variants of a known ransomware family that were developed on Android devices using the Android integrated development environment," he writes.
"However, the ability to create malware on mobile devices may open up new avenues in the future creation of malware."
As the techniques used to create new ransomware threats on mobile devices are relatively new, the principal analyst adds that a bit of explanation is in order.
"These ransomware threats were created using the rapid application development (RAD) model of software development. This method is typically used for software that requires rapid prototyping and is driven by user interface requirements," he says.
"This is a particularly suitable way to develop mobile applications because of their reliance on a strong graphical user interface (GUI)."
According to Venkatesan, RAD utilises GUI builders that can make it easier to build applications because of their drag-and-drop wizard functionality, which can be used to build the interface and app.
"Integrated development environments (IDEs), another integral part of the RAD model, help developers to rapidly build an application by automatically generating boiler-plate code," he explains.
"These functions make it easier for developers, and in this case, attackers, to rapidly create software without worrying too much about planning and design."
In order to actually develop ransomware on mobile devices, Venkatesan explains that the tools required to build Android apps are computer-based software.
"That means, in order to use them to build Android apps, the developer will need a computer, which is the most common practice when it comes to app development. In this specific case, attackers have used an IDE to design, build, implement, modify, and sign variants of Android.Lockdroid.E directly on mobile devices," he explains.
"Manipulating the existing code to create newer variants with different configurations is nothing new from a traditional malware development practice."
However, Venkatesan adds that the adoption of RAD methodology shows how attackers are attempting to find quicker, more flexible ways to create malware.
To protect against these threats, Symantec recommends the people at risk keep their software and operating systems up to date, don't install apps from unfamiliar sources, back up their devices and install a suitable mobile security app.

It is unusual nowadays to find night-time location free of artificial light, so it is not surprising that we fail to notice that scenes viewed by moonlight are almost colourless. The human eye is insensitive to colour when light levels are low. By the light of the full moon we can see well enough to move around in unfamiliar terrain, but we cannot see its colour. To the eye, the trees, the grass and the sky above appear as shades of grey by moonlight, but our photograph reveals that the colours are still there. The most surprising is the blueness of the moonlit sky, which has never been described as blue throughout recorded history. It is blue for the same reason it is by day, because sunlight, reflected by the moon is scattered by the atoms and molecules of the earth's atmosphere.
The photograph was a 20 minute exposure on colour transparency film, using a wide angle lens set at F/4. Immediately over the right hand railing on the dome are trails of the stars of the Southern Cross laid on its side. The red-orange trail of the star Acrux was almost touching the railing when the exposure was started. The wavy lines at eye level are astronomer's flashlights as they walk across the scene to the dome. A much longer exposure of the same scene without moonlight is seen here.

Resistance is costly: trade-offs between immunity, fecundity and survival in the pea aphid
Gwynn, D. M., Callaghan, A., Gorham, J., Walters, K. F. A. and Fellowes, M. D. E. (2005) Resistance is costly: trade-offs between immunity, fecundity and survival in the pea aphid. Proceedings of the Royal Society B-Biological Sciences, 272 (1574). pp. _PHONE_. ISSN _PHONE_

Parasitoids are among the most important natural enemies of insects in many environments. Acyrthosiphon pisum, the pea aphid, is a common pest of the leguminous crops in temperate regions. Pea aphids are frequently attacked by a range of endoparasitic wasps, including the common aphidiine, Aphidius ervi. Immunity to parasitoid attack is thought to involve secondary symbiotic bacteria, the presence of which is associated with the death of the parasitoid egg. It has been suggested that there is a fecundity cost of resistance, as individuals carrying the secondary symbionts associated with parasitoid resistance have fewer offspring. Supporting this hypothesis, we find a positive relationship between fecundity and susceptibility to parasitoid attack. There is also a negative relationship between fecundity and off-plant survival time (which positively correlates with resistance to parasitoid attack). Taken together, these results suggest that the aphids can either invest in defence (parasitoid resistance, increased off-plant survival time) or reproduction, and speculate that this may be mediated by changes in the aphids' endosymbiont fauna. Furthermore, there is a positive relationship between aphid size and resistance, suggesting that successful resistance to parasitoid attack may involve physical, as well as physiological, defences.

'20 Questions' Game Helps Robots Understand Humans
Robots and humans
Trending in the latest AI news, is the famous 20 questions game! Information scientists at the U.S. Army Research Laboratory and the University of Michigan have borrowed from the "20 Questions," to make an important step towards helping robots maintain continuous and purposeful conversation with humans. They have developed an optimal strategy for asking a series of yes/no questions that rapidly achieves the best answer.
In the game, a player wishes to estimate an unknown value on a sliding scale by asking a series of questions whose answer is binary (yes or no). In this way, scientists say, their research findings could lead to new techniques for machines to ask other machines questions, or for machines and humans to query each other.
ARL senior scientist Dr. Brian Sadler teamed with University of Michigan researchers Hye Won Chung, Lizhong Zheng, and Professor Alfred O. Hero to conduct the study, which appears in the February 2018 issue of the IEEE Transactions on Information Theory.
AI understands humans with questions | iTMunch
The work is part of a larger study to develop methods for machines and humans to interact.
"It is well known that artificial intelligence systems, such as those found nowadays on every smartphone, can answer at least some questions," Sadler said. "They can even win a game like Jeopardy, focusing on only one question at the time. A real, purposeful conversation, especially in complicated military environments, is different. It requires the AI system to understand a whole sequence of questions and answers, and to handle every question or answer with consideration of what has been asked or answered before. Such computer algorithms do not yet exist, and the scientific theory for building such algorithms is not yet developed."
Sadler said it is a signifcant challenge to find ways for a machine to query a human that efficiently takes advantage of the human's expertise.
"Humans are particularly good at accurately answering yes/no questions," he said. He explained that it is important to minimize the number of queries, while maximizing the value of each one, so as not to waste the human's time or endanger a soldier who has duties to perform in a dangerous environment.
The 20 questions game is a classic pastime, where players can only ask questions whose response is yes or no, while attempting to identify an object. The sequence of questions is designed so that the player can rapidly figure out the answer: "Is it bigger than a breadbox," "is it alive," and so on; however, in the Army problem, it is possible that the question may be answered in error.
"Unlike the actual 20 Questions game, we admit the possibility that a question might be answered in error," he said. "We call this the noisy 20 questions game."
ARL and University of Michigan researchers developed a method to automatically formulate a sequence of questions to narrow down the error and provide an answer to the question, "what is the value of x." The researchers have shown that their querying will achieve the minimum mean-square error between their best guess and the unknown true value of x.

Moving forward, as part of research into artificial intelligence and human-machine teaming, ARL will apply methods such as the 20 Questions paradigm to Soldier-robot teaming.

Set) is the category of "cospans" of finite sets. The objects are finite sets, and a morphism from X to Y looks like this:
X Y \ / F\ /G \ / v v SIf you remember the "Tale of Groupoidication" starting in "week247", you'll know about spans and how to compose spans using pullback. This is just the same only backwards: we compose cospans using pushout.
But here's the point. A 2d cobordism is itself a kind of cospan:
X Y \ / F\ /G \ / v v Swith two collections of circles included in the 2d manifold S. If we take connected components, we get a cospan of finite sets. Now we've lost all information about handles! And the circle - which was a commutative Frobenius algebra - becomes a mere one-point set - which is a special commutative Frobenius algebra.
Now for a few examples of non-semisimple Frobenius algebras.
First, take the exterior algebra ΛV over an n-dimensional vector space V, and pick any nonzero element of degree n - what geometers would call a "volume form". There's a unique linear map
e: ΛV → C
which sends the volume form to 1 and kills all elements of degree < n. This is a lot like "integration" - and so is taking a trace. So, you should want to make ΛV into a Frobenius algebra using this formula:
g(a,b) = e(a ^ b)
where ^ is the product in the exterior algebra. It's easy to see this is nondegenerate and satisfies the Frobenius axiom:
g(ab,c) = e(a ^ b ^ c) = g(a,bc)
So, it works! But, this algebra is far from semisimple.
If you know about cohomology, you should want to copy this trick replacing the exterior algebra by the deRham cohomology of a compact oriented manifold, and replacing e by "integration". It still works. So, every compact manifold gives us a Frobenius algebra!
If you know about algebraic varieties, you might want to copy this trick replacing the compact manifold by a complex projective variety. I'm no expert on this, but people seem to say that it only works for Calabi-Yau varieties. Then you can do lots of cool stuff:
20) Kevin Costello, Topological conformal field theories and Calabi-Yau categories, available as arxiv:math/_PHONE_.
Here a "Calabi-Yau category" is just the "many-object" version of a Frobenius algebra - a Calabi-Yau category with one object is a Frobenius algebra. There's much more to say about this wonderful paper, but I'm afraid for now you'll have to read it... I'm getting worn out, and I want to get to the new stuff I just learned!
But before I do, I can't resist rounding off one corner I cut. I said that Frobenius algebras show up naturally by taking string theory and watering it down: ignoring the geometrical structure on our string worldsheets and remembering only their topology. A bit more precisely, 2d TQFTs assign linear operators to 2d cobordisms, but conformal field theories assign operators to 2d cobordisms equipped with conformal structures. Can we describe conformal field theories using Frobenius algebras?
21) Ingo Runkel, Jens Fjelstad, Jurgen Fuchs, Christoph Schweigert, Topological and conformal field theory as Frobenius algebras, available as arXiv:math/_PHONE_.
But, you need to use Frobenius algebras inside a modular tensor category!
I wish I had more time to study modular tensor categories, and tell you all about them. They are very nice braided monoidal categories that are not symmetric. You can use them to build 3d topological quantum field theories, and they're also connected to other branches of math.
For example, you can modular tensor categories consisting of nice representations of quantum groups. You can also can get them from rational conformal field theories - which is what the above paper by Runkel, Fjelstad, Fuchs and Schweigert is cleverly turning around. You can also get them from von Neumann algebras!
If you want to learn the basics, this book is great - there's a slightly unpolished version free online:
22) B. Bakalov and A. Kirillov, Jr., Lectures on Tensor Categories and Modular Functors, American Mathematical Society, Providence, Rhode Island, 2001. Preliminary version available at _URL_
But if a book is too much for you, here's a nice quick intro. It doesn't say much about topological or conformal field theory, but it gives a great overview of recent work on the algebraic aspects of tensor categories:
23) Michael Müger, Tensor categories: a selective guided tour, available as arXiv:0804.3587.
Here's a quite different introduction to recent developments, at least up to 2004:
24) Damien Calaque and Pavel Etingof, Lectures on tensor categories, available as arXiv:math/_PHONE_.
Still more recently, Hendryk Pfeiffer has written what promises to be a fundamental paper describing how to think of any modular tensor category as the category of representations of an algebraic gadget - a "weak Hopf algebra":
25) Hendryk Pfeiffer, Tannaka-Krein reconstruction and a characterization of modular tensor categories, available as arXiv:0711.1402.
And here's a paper that illustrates the wealth of examples:
26) Seung-moon Hong, Eric Rowell, Zhenghan Wang, On exotic modular tensor categories, available as arXiv:07108.5761.
The abstract of this makes me realize that people have bigger hopes of understanding all modular tensor categories than I'd imagined:
It has been conjectured that every (2+1)-dimensional TQFT is a Chern-Simons-Witten (CSW) theory labelled by a pair (G,k), where G is a compact Lie group, and k in H4(BG,Z) is a cohomology class. We study two TQFTs constructed from Jones' subfactor theory which are believed to be counterexamples to this conjecture: one is the quantum double of the even sectors of the E6 subfactor, and the other is the quantum double of the even sectors of the Haagerup subfactor. We cannot prove mathematically that the two TQFTs are indeed counterexamples because CSW TQFTs, while physically defined, are not yet mathematically constructed for every pair (G,k). The cases that are constructed mathematically include:
- G is a finite group - the Dijkgraaf-Witten TQFTs;
- G is a torus Tn;
- G is a connected semisimple Lie group - the Reshetikhin-Turaev TQFTs.
We prove that the two TQFTs are not among those mathematically constructed TQFTs or their direct products. Both TQFTs are of the Turaev-Viro type: quantum doubles of spherical tensor categories. We further prove that neither TQFT is a quantum double of a braided fusion category, and give evidence that neither is an orbifold or coset of TQFTs above. Moreover, the representation of the braid groups from the half E6 TQFT can be used to build universal topological quantum computers, and the same is expected for the Haagerup case.
Anyway, now let me say what Vicary and Melliès have been explaining to me. I'll give it in a highly simplified form... and all mistakes are my own.
First, from what I've said already, every commutative special Frobenius algebra over the complex numbers looks like
C ⊕ C ⊕... C ⊕ C
It's a direct sum of finitely many copies of C, equipped with its god-given bilinear form
g(a,b) = tr(La Lb)
So, this sort of Frobenius algebra is just an algebra of complex functions on a finite set. A map between finite sets gives an algebra homomorphism going back the other way. And the algebra homomorphisms between two Frobenius algebras of this sort all come from maps between finite sets.
So, the category with:
is equivalent to FinSetop. This means we can find the category of finite sets - or at least its opposite, which is just as good - lurking inside the world of Frobenius algebras!
Coecke, Pavlovic and Vicary explore the ramifications of this result for quantum mechanics, using Frobenius algebras that are Hilbert spaces instead of mere vector spaces. This lets them define a "†-Frobenius algebra" to be one where the comultiplication and counit are adjoint to the the multiplication and unit. They show that making a finite-dimensional Hilbert space into a commutative special †-Frobenius algebra is the same as equipping it with an orthonormal basis.
There's no general way to duplicate quantum states - "you can't clone a quantum" - but if you only want to duplicate states lying in


Dog Friendly Garden: Fresh Water For Your Pet
Dogs, like us humans, are made up of nearly 80 percent water. Fresh water is essential to keep the body running smoothly. Dogs need access to water at all times…both indoors and outdoors. As pet parents, its extremely important for us to ensure our dogs have a clean water source to quench their thirst and cool them down.
Water nourishes, cleanses, and hydrates all living creatures on Earth. It is essential for survival.
Top Four Reasons Water Is Important For Dogs:
1. Water helps dogs function overall. It helps your pooch digest food, think while athletically catching a frisbee, breathe in fresh oxygen, and pulse blood through the veins. The brain and muscles both require water to work well on a daily basis.
2. Water acts as a toxin flush. Without sufficient water, toxins can build up in the body and damage the heart and kidneys. Since blood is mostly water, and oxygen is transported to the body cells by red blood cells and toxins are removed by the blood cells, daily intakes of water are necessary to cause these exchanges.
3. Water regulates body temperature. It helps our dogs to remain cool in warm weather. They drink the refreshing liquid, they jump into the kiddie pool to cool down on a hot day, and they pant. Panting eliminates water through the tongue, causing a need for additional water to replenish.
4. Water helps the dogs scent function. Dogs have a remarkable ability to recognize and remember scents, far superior to that of humans. A dog's sense of smell may be as much as 100 times better than ours, making it the most sensitive and vulnerable part of its body. Adequate amounts of water are necessary to keep their noses moist. Dry noses don't scent as well.
Check you dog's water bowl or fountain throughout the day to make sure it is full of clean water. This is especially important outside where water can quickly evaporate on a hot day. (Water evaporates faster than you may realize, particularly on warm and windy days)
We recommend placing the water source in the shade to keep it cooler. Most dogs enjoy some ice cubes in their water on a summer day!
More Reasons Water Is Essential For Your Dog's Good Health:
- Water burns fuel which turns into energy
- Water helps to digest and absorb nutrients
- Water replaces other body fluids that are lost through bodily secretions
- Water carries nutrients to other cells of the body while excreting toxins from the body, allowing for proper elimination. Without water, these organs could not function properly.
- Water is necessary to regulate the blood's acid level
Water Dishes Perfect For A Dog Friendly Garden
There are many functional and attractive dog water dishes and fountains on the market now. They range from the "high-tech" types with sensors that distribute water at your pet's touch, to constant streaming varieties hooked up to a garden hose, to dispenser systems with flow-control valves, to the good old-fashioned weighted water bowls that never go out of style.
Remember: The water bowl or water bottle needs cleaning every day. Bacteria that you can't see can grow in a bottle or bowl, giving the water a funny taste and discouraging your pet from drinking. Even worse, some kinds of bacteria can make animals sick. Develop the habit of giving the bowl a quick scrub with dish soap before you fill it in the morning.
How Much Water Should My Dog Drink Per Day?
It all depends on his/her activity level, size, age, and weather conditions. In general, an average dog needs to drink between 8 – 17 ounces of water per 10 pounds per pet medical experts. In other words: A 50 pound dog needs between 40 and 85 ounces of liquid refreshment to stay happy and hydrated.
Signs of Dehydration in Dogs
In general, a healthy dog will drink enough water daily to stay well hydrated, but there are a few instances where dehydration can occur. Dogs suffering from illnesses like kidney disease, diabetes, cancer and pregnant/nursing animals are at risk of becoming dehydrated more readily.
To check your dog for dehydration, try this: Pick up a fold of loose skin over the top of the shoulder blades, pull it up gently and release it. Watch for the skin to fall back into place. Under normal circumstances, healthy dog skin should quickly return to place without any hesitation. If dehydration is present, the skin will slowly return or may even stay up for a time before falling back into place.
Another way to look for dehydration is in the dog's mouth. If the gums appear dry, sticky or pale, this is a sign of illness and dehydration. Dehydrated pets will also have dry, sunken eye balls and a dry nose and mouth. If your pet's dehydrated, your veterinarian can give him intravenous fluids and find out what caused the problem.
If you are concerned that your dog is not getting enough water to maintain health, talk to your veterinarian for advice. Maintaining proper hydration is too important to your dog's health to ignore.
Exercise = More Water
Just like people, pets need more water when they're exercising. If you take your dog out for a long walk or run, bring along some water for him. Most pet stores sell light-weight, collapsible or clip on travel water bowls that are easy to carry. After a fun fetch or disc session in the backyard…steer your pup over to his water bowl.
As long as you keep an eye on your pet and make sure his water is clean and plentiful, you shouldn't have a problem. A dog can go a long time without food, but without water he's not going to survive.

Most people associate the development of gas masks with the hell of World War I, but they appeared earlier to protect those working in various dangerous areas. You are probably familiar with the image of a doctor wearing a beak mask during a major European plague epidemic between 1347-52, which, although not intentionally, can be regarded as a rudimentary respiratory protection device.
During the nineteenth century, the first masks providing targeted protection began to appear among miners and firefighters. Their common use for military purposes was indeed due to the emergence of various chemical weapons during the First World War, and their use soon seemed inevitable to the civilian population as well. Nuclear mass hysteria during the Cold War briefly made gas masks a basic item in households, but today, fortunately, it has once again become a feature of only a few specific jobs.

Gantrade's P-1000 and P-2000 are oligomeric diamine curatives based on the p-aminobenzoate ester of PTMEG 1000 and PTMEG 2000, respectively. The Gantrade P-1000 is similar to Versaink® P-1000. The P-2000 is a new material, developed for applications where a lower Durometer is required. A diamine based on the p-aminobenzoate of PTMEG 650 is also available from Gantrade Corporation.
Because of their reduced reactivity and low melting nature, these oligomeric diamines can be used in low temperature cures with either TDI and MDI systems. These characteristics afford significant processing advantages, including a lower temperature processing window, lower mixing temperature requirements, better maintenance of accurate mix ratios and lower shrink values due to lower cure temperatures. This facilitates mixing, hand-batching, casting, coating and molding operations. They can also be used as co-curatives and impact-flexibility modifiers for glycidyl type epoxy resins.
The chemical structure of Gantrade's P-1000 and P-2000 is shown below. The n value for the PTMEG segment is 13-14 for the P-1000 and 27-28 for the P-2000. The molecular weights are 1238 and 2238, respectively. The molecular weight distribution of these diamines range from 2.2 to 2.9.
The general attributes of the P-1000 and P-2000 curatives in polyurea elastomers include the following:
- Low reactivity and a wide processing latitude with MDI prepolymers having NCO contents of 9-30 %
- pot lives of 20-30 minutes at 25° C with high NCO content MDI prepolymers.
- pot lives of 5-10 minutes at 60° C
- P-1000 is a liquid at room temperature; P-2000 is a low melting wax.
- Contribute the benefits of PTMEG soft-segments including excellent resiliency/rebound properties, good tensile and tear strengths, toughness and abrasion resistance, especially impingement abrasion resistance..
- Hydrolysis and chemical resistance.
- Good flexibility and impact resistance at low temperatures.
- Shore A Durometer values can range from 75-95 for P-1000 and 60-80 for P-2000 with MDI prepolymers, depending on the % NCO levels.
- A low order of toxicity.
Typical sales specifications for Gantrade's P-1000 and P-2000 are provided below.
Sales Specifications for Oligomeric Diamine
Performance properties for an MDI-ether based polyurea elastomer produced from P-1000 are shown below.
Performance Data in Polyureas
Property characterizations on the polyurea resulting from P-1000 and Isonate® 143L, a higher functionality, carbodiimide modified MDI, have been well studied and reported in the literature. References are available from Gantrade Corporation.
As low melting curatives, both P-1000 and P-2000 can be mixed with liquid TDI and MDI prepolymers at lower temperatures and cast into molds. These systems are generally post-cured for 16 hours at 80° C. Room temperature cures generally require two weeks to achieve complete cure. The glass transition temperatures of polyureas cured with both P-1000 and P-2000 vary based on factors such as the stoichiometry ratios and % NCO. But the Tg's of the soft segments are generally below minus (-) 60° C and for the polyureas, minus (-) 45-55° C, when measured by thermal analysis.
Depicted below is the chemical reaction and polyurea structure when reacted with MDI. This provides a representation of the hard block and soft-block segments of a polyurea based on P-1000. Phase separation occurs because of the chemical dissimilarity of the soft and hard phases, and hydrogen bonding, resulting in a hard phase that is dispersed in the soft PTMEG matrix. Additionally, the hard phase can reinforce the soft matrix to create a pseudo-crosslinked backbone. This enhances the mechanical properties of the polyurea.
The application areas include hot and cold cast operations, coatings, adhesives, sealants, ballistic armor, polyurea spray systems and field repair polyurea and epoxy kits. These diamines are ideal for curing large parts where heat build-up is an issue with other higher reactivity curatives.
Gantrade offers the P-1000 and P-2000 in galvanized iron or plastic drums, with a net eight of 20 Kg or 50 Kg. Sample quantities are generally 1 Kg. in size.
Gantrade recommends a thorough review of our SDS prior to handling these curatives, and observance of the correct safety precautions and handling requirements. The diamines should be stored in a well ventilated and dry location. Be sure to keep these products away from sunlight.

Currently local server virtual provides are used in fedora, the one I am aware is smtpdaemon for a mail server listening on the smtp port. webserver is also another potential candidate, but as seen below it doesn't seems to be used for a web server listening on the http port. Therefore the naming and the exact meaning of those virtual provides is not clear. There is no way to discover the name of such virtual provides, nor to list them all.
This draft proposes a naming scheme for virtual provides corresponding with local servers listening on a specific port, with a strict meaning of the provides and a naming scheme generic and rule based.
The aim is not to inflate the number of virtual provides, they should only be added if needed, but to provide a more systematic naming scheme.
Virtual provides corresponding with local servers should be named along
port_name being the service name associated with that port number in /etc/services, or the port number when no record exists in /etc/services (but in that case it is doubtful that a virtual provides is useful).
So, for example a virtual provides for a server listening on port 80 should be server(http).
Things to do if the proposal is accepted
collect the virtual server provides
Currently smtpdaemon. Don't hesitate to add more if you know them.
change the virtual provides
For the known existing virtual provides.
smtpdaemon should be changed to server(smtp).
# repoquery --whatprovides smtpdaemon
It looks like all the packages that should provide this virtual provide are listed here.
# repoquery --whatrequires smtpdaemon
I remember having inspected those packages and if I recall well, they really requires a local smtp server.
webserver status is less clear. Indeed there are packages that set up an http server that are not providing this virtual provide:
# repoquery --whatprovides webserver
And it seems that none of the packages that requires webserver requires a local http server:
# repoquery --whatrequires webserver
Instead most of them seem to require a cgi server, and some clearly requires the apache web server since they install their files in apache specific directories.
Therefore the semantics of the webserver virtual provides may be more along a web server providing cgi support (namazu-cgi, nut-cgi, darcs-server, qdbm-cgi) and therefore can stay. Sometimes it means a cgi server, but also also means a server with apache like web server configuration directory and config file (bugzilla, htdig-web, phpMyAdmin, postgresql-pgpoolAdmin, wordtrans-web) in that case the requires may better be httpd, but this is out of the scope of that proposal.
nut-devel seems to be a mistake (hopefully the merge review isn't still done).
A server(smtp) provides should be added to the packages providing smtpdaemon by F-9. The Requires for all Fedora packages should be changed to use the new provides by F-9, too. When you implement the new Provides, please leave the old ones so that third party packages that have grown to depend on them can continue to function, at least for F-9. After F-9 keeping or removing the provides is left to the packager.
PatriceDumas will fill bugs and provide patches for spec files as soon as (and if) FESCo ratifies this proposal.
There is a need for a server(xdmcp) in ltsp5, and for the corresponding virtual provides in gdm, kdm, xdm, wdm. PatriceDumas is also volunteering to take care of that.

HISTORY OF FOIE GRAS
Literally translated from French, foie gras means "fat liver," but its origins date back far before French cooking made it a delicacy. The ancient Egyptians hunted and then domesticated geese, and discovered that waterfowl developed large, fatty livers after eating large amounts in preparation for migration. To replicate this naturally occurring large liver, the Egyptians, over 4000 years ago, developed the technique now known as gavage to produce a fattier bird. Colorful relief paintings found on the tombs of aristocratic Egyptians depict the hand-feeding of geese, which served as an important source of nutrition around the Nile region. The practice of gavage spread throughout the Mediterranean, and was adopted by the Greeks and then the Romans, the latter of whom made foie gras into a delicacy in its own right. As Rome expanded territorially, its gastronomic influence also expanded, turning foie gras into a food enjoyed by gourmands, who fattened their ducks explicitly for the purposes of its production.
After the fall of Rome, and during the medieval period, it was the Jewish population who kept the tradition of foie gras alive. Goose meat served as an excellent source of nutrition and the animal also provided cooking fat that conformed to Jewish law. Wherever Jews moved across Europe during the Middle Ages, they brought with them the tradition of goose fattening.
During the late sixteenth-century Renaissance, classical texts and cookbooks were revisited, and interest in foie gras was once again piqued. In France, Louis XIV, a gourmand, enjoyed haute cuisine, but his tastes began to trickle down to the aspirations of the French middle class. After the French Revolution, with centuries of food admiration so deeply etched into their culture, the bourgeois became the new consumers of cuisine, and they began to frequent a new establishment known as the restaurant. Chefs who had lost their aristocratic patrons cooked instead for Parisian middle class society.
Foie gras became popularized in the United States in the late nineteenth century as Americans brought a love of the food back with them from travels in Europe. It was not until the latter part of the twentieth century, however, that American farmers began to produce foie gras here in the U.S. The majority of foie gras consumed by Americans now comes from small North American farms. Demand for foie gras has grown, prompting chefs across the country to add the item to their menus. And though it has enjoyed a long history, foie gras is still produced using the traditional methods passed down by generations – by hand, and with care and attention that small, artisan farmers give to their ducks.
A useful timeline of the history of foie gras, beginning in 2498 BC and ending in 2008 AD, can be seen at The Wall Street Journal website.

New World Trade Center deemed tallest US skyscraper
New York's new One World Trade Center will be the tallest US skyscraper when it is completed, topping the former Sears Tower in Chicago, a panel of architects decided Tuesday.
Architects at the Council on Tall Buildings and Urban Habitat agreed that the trade center's 124.4 meter (408 foot) antenna was a permanent architectural feature of the building and should be counted in determining its height.
"The design of One World Trade Center, as explained to us, reinforces its role as a symbol of resurgence on this important site," said CTBUH Executive Director Antony Wood.
"In particular, the spire which holds the beacon light, shining out at the symbolic height of 1,776 feet, is especially poignant -- echoing the similarly symbolic beacon atop the Statue of Liberty across the water."
The new One World Trade Center is built on the site of the original World Trade Center, whose iconic twin towers were toppled in the September 11, 2001 attack.
Without the antenna, the new building's 417 meter (1,368 foot) height would be topped by the former Sears Tower in Chicago, now officially named the Willis Tower, which rises 442 meters (1,450 feet) from the ground.
Neither skyscraper comes close to the world record, which is held by the 830-meter-high (2,723-feet-high) Burj Khalifa in Dubai.

Here we present an approach for modeling sensory processing, termed the Nonlinear Input
Model (NIM), which is based on the hypothesis that the dominant nonlinearities imposed by physiological mechanisms arise
from rectification of a neuron's inputs. Incorporating such 'upstream nonlinearities' within the standard linear-nonlinear (LN)
cascade modeling structure implicitly allows for the identification of multiple stimulus features driving a neuron's response,
which become directly interpretable as either excitatory or inhibitory.
Because its form is analogous to an integrate-and-fire
neuron receiving excitatory and inhibitory inputs, model fitting can be guided by prior knowledge about the inputs to a
given neuron, and elements of the resulting model can often result in specific physiological predictions.
providing an explicit probabilistic model with a relatively simple nonlinear structure, its parameters can be efficiently
optimized and appropriately regularized.... "

Bang!: How is the Energy of Seismic P-Waves Transmitted Through the Earth?
How is the energy of seismic P-waves transmitted through the earth?
- Masking tape
- 5 marbles
- Cut 5 pieces of string, each 12 inches (30 cm) long.
- Tape one piece of string to each of the marbles.
- Tape the free end of each string to the edge of a table. Adjust the position and length of the strings so that the marbles are the same height and touching each other.
- Pull one of the end marbles to the side, and then release it.
- Observe any movement of the marbles.
The marble swings down, striking the closest marble in its path, and stops moving. The marble on the opposite end swings outward, and strikes its closest neighboring marble when it swings back into its original position. The cycle of the end marbles swinging back and forth continues for a few seconds.
Raising the end marble gives it energy, which is transferred to the marble it strikes. This energy is passed from one marble to the next, as each marble pushes against the next. The end marble is pushed away from the group. The transfer of energy from one marble to the next simulates the transfer of energy between particles of the earth during a seismic P-wave (primary pressure wave of an earthquake).
The first sign that an earthquake has occurred is the hammerlike blow felt and heard as a P-wave exits through the earth's surface. Before that, P-waves move through liquids and solids by compressing (pressing together) the particles of earth directly in front of them. The compressed particles quickly spring back to their original position as soon as the energy moves on. The crust of the earth moves upward as it is hit with the energy of the P-wave, and then settles back into place when the energy moves on.
- Would it affect the transmission of energy if the marbles were not in line? Stick pieces of clay under the strings on the side of the table in order to change the position of the marbles. Be sure that the marbles touch at some point, but that each marble is at a different height.
- Would changing the distance between particles affect the transfer of energy? Repeat the original experiment, moving the pieces of tape supporting the marbles farther apart so that there is a slight separation between each marble.
- Use a Slinky to demonstrate the particle movement of a seismic P-wave as it moves from the focus (starting point) of an earthquake to the epicenter (the point on the earth's surface directly above the focus). The Slinky can be used as part of a project presentation by slightly stretching it vertically and attaching its top and bottom loops to the display. Compress four to five loops together at one end, then release.
- Seismic waves move more slowly through sand because the energy of the waves moves forward in different directions as the sand particles move outward in all directions. To demonstrate this, cover the end of a paper towel tube with a paper towel. Secure the paper towel to the tube with a rubber band. Fill the tube with uncooked rice or bird seed. Use your fingers to press down on the rice as you try to push the rice down and out through the paper towel.
Check it Out!
P-waves are the swiftest seismic waves. Find out the speed of P-waves as they travel through the different layers of the earth's interior: crust, mantle, and core. Display a diagram of a cross section of the earth, with speeds of P-waves indicated for each layer.

Bird in the bush
"A bird in the hand is worth two in the bush."
A proverb of which one meaning is it is better to have something for sure (low risk) than something speculative (high risk). The paradox part is that investors will often not do a probability analysis for lowest risk/highest return. They will take their chances of getting something more speculatively than they will getting something less as a sure thing. Better to have than to speculate on the one hand but better to speculate than have on the other. Since most choose to speculate, we can extrapolate that this saying is intended as a caution to incautious people.
Due to the phrasing of the sentence (and the emphasis given to the position of the bird) it is plain that it is 'not a paradox'.
