'Twin Peaks' Brings Back Miguel Ferrer as Albert Rosenfield
Twin Peaks Brings Back Miguel Ferrer as Albert Rosenfield
Miguel Ferrer has come aboard to reprise his role from the original Twin Peaks as FBI agent Albert Rosenfield in Showtime's revival series.
1k share
Production has been under way for the past two months on Showtime's Twin Peaks revival series, but as of now, the only cast member the network has confirmed is Kyle MacLachlan as Special Agent Dale Cooper. Over the past few months, numerous rumors and casting reports have surfaced revealing new and returning cast members coming aboard, but nothing official has surfaced from the network quite yet. Today, we have another casting report from Deadline, revealing that Miguel Ferrer has signed on to reprise his role as FBI agent Albert Rosenfield in the revival series.
Miguel Ferrer appeared in eight episodes of the original series as the FBI forensics expert, who often clashed with Twin Peaks sheriff Harry S. Truman (Michael Ontkean). Ironically, a report surfaced last month that revealed Michael Ontkean will not be returning, since he retired from acting several years ago. There has been speculation that the producers may try to re-cast the role. It has been rumored that Robert Forster is being courted to play Truman, but others contend that he may actually be playing a different lawman altogether.

The site also claims that original series stars David Patrick Kelly and Richard Beymer are coming back to reprise their roles as brothers Jerry Horne and Benjamin Horne. Other original cast members rumored to be returning are Mädchen Amick (Shelly Johnson), Sherilyn Fenn (Audrey Horne), Sheryl Lee (Laura Palmer) and Dana Ashbrook (Bobby Brooks). It remains to be seen when and if these actors are confirmed by Showtime, but several of these actors have already been spotted in photos from the set.
New cast members include Amanda Seyfried, Balthazar Getty, Robert Knepper, Peter Sarsgaard and Jennifer Jason Leigh, although nothing has been revealed about their characters yet. There have been rumors that Amanda Seyfried may be playing the daughter of Dale Cooper and Heather Graham's Annie Blackburn, but that has yet to be confirmed. It isn't known how many more original cast members are slated to come back, and how many new characters have yet to be cast.
Series creators David Lynch and Mark Frost wrote one massive script for the upcoming series. David Lynch is directing the script like one huge movie, and cutting the show into individual episodes in post-production, so we likely won't know how many new episodes Showtime will air for quite some time. Story details have not been released yet, and it isn't known how long principal photography will continue for. Unfortunately, it was recently revealed that the new series won't premiere until the year 2017, after Showtime had initially planned a 2016 debut. Miguel Ferrer currently stars as a series regular on CBS' NCIS.

iZettle forced to stop processing Visa payments in three European markets
31 July 2012 @ 11:18
Swedish mobile payment firm iZettle has been forced to stop processing Visa card transactions in three European markets; Denmark, Finland and Norway. Visa Europe said Monday that the iZettle mobile payment service does not meet its policy requirements in these markets.
The Swedish firm provides apps and hardware that enable iOS and Android devices to function as payment card readers, similar to the Square model created by Twitter founder Jack Dorsey.
iZettle customers will no longer be able to process person-to-person or business-to-consumer Visa card payments in Denmark, Finland and Norway from August 1, 2012.
The news is expected to be welcomed by Square, which provides a similar solution in the US, and has benefitted from investment from Visa Inc. Although Visa Inc. and Visa Europe are independently operating companies, Visa Europe is a minority stockholder in Visa Inc and the two firms work together to ensure the interoperability and security of Visa products and systems.
Another rival to iZettle, mPowa, publicised Visa Europe's decision in a recent press release.
IZettle CEO Jacob de Geer recently told Telecoms.com that the firm's competitive advantage is that it provides an end-to-end solution in a fragmented market.
"We take care of hardware and interface for customer. We handle payments to your bank account and we handle support," he said. "The rest of the value chain is extremely fragmented. There's a terminal supplier, and a bank, and the merchant, but with us, we provide everything."
He added that the firm is uninterested in the classic enterprise and mid-tier model, which generates the bulk of transactions.
"There are no margins there whatsoever; there are so many players there. The problem with the existing value chain is that the way it's created makes it unprofitable to target the prosumer."
De Geer admitted in a recent blog post that he was disappointed with the situation with Visa Europe, but added: "We hope we can bring Visa card acceptance back to Denmark, Finland and Norway shortly and will of course keep you posted on the development."
iZettle has recently benefitted from invesment of its own from a number of financial firms, most notably Visa's competitor MasterCard. iZettle will continue to accept MasterCard and American Express cards in Finland, and Diners Club cards in Denmark and Norway. It also continues to process mobile payments in Sweden and the UK.

Really bad news for iZettle. That's the prize for Mastercard as strategic investor. More dangerous for them is that new competitors like e.g. the German square clone payleven are going to provide the chip and pin technology.

First, they couldn't take Visa payments in the UK and now this. This is not good for iZettle which means another win for mPowa (www.mpowa.com).

Sunday, March 3rd
Pianist Mike del Ferro
Dutch pianist Mike del Ferro is a highly sought-after composer, pianist and arranger who writes and performs in an impressive array of musical genres.
He has travelled the world extensively (more then 100 countries), searching for collaborations with musicians from cultures quite different to his own, and the musical results have been eye-opening, building musical bridges between cultures not normally within reach of each other. He has managed to combine elements of the revered canons of Western music interspersed with the audacity of jazz improvisation, and paying tribute to the ancient structures of Asian, South American and African traditional music.
He has recently signed a contract with Challenge records for a series of 10 CD's, collaborations with musicians from all over the world, based on his travels.The first trio CD will be released worldwide in the fall of 2011, and the second production in the spring of 2012, with guest artists from Brazil.
Mike's father was opera singer Leonard del Ferro (1921-1992), who sang and recorded with Maria Callas, and his childhood was thus filled with music of the highest order.A native of Amsterdam, he started his career studying classical piano at the age of nine and,
after falling in love with jazz, he focused his studies on jazz and received a Masters of Music in Contemporary Music from the Amsterdam Conservatory.
In 1989 he won First Prize at the Rotterdam Jazz Piano Competition, the Soloist Prize at the Europe Jazz Contest in Brussels, and First Prize at the Karlovy Vary Jazz contest and from 1993-1996 studied composition and arranging with Bob Brookmeyer at the Musikhochschule in Cologne, Germany. In 1995 Mike was appointed to the faculty of the Royal Conservatory in Gent, Belgium where he taught jazz piano until 1997. His reputation as a soloist, accompanist, composer and arranger has led to worldwide performances, recordings and tours with musicians such as Toots Thielemans, Jack DeJohnette, Oscar Castro Neves, Deborah Brown, Erik Truffaz, Jorge Rossy, Sibongile Khumalo, Carl Allen, Scott Hamilton, Richard Galliano, Thijs van Leer (Focus), Harold Land, Jan Akkerman, Norma Winstone, Benny Bailey, Candy Dulfer, Trijntje Oosterhuis, Badi Assad, Fernanda Porto, Madou Diabate and Maria Pia deVito. He has also recorded dozens of albums in many different genres from Dixieland to Salsa and has arranged music for animation for Danish animator and Oscar winner, Börge Ring.

The Herb ephedra, also known by its Chinese name Ma huang, has been used in Traditional Chinese Medicine since 3000 B.C. to treat colds, asthma, and other upper-respiratory disorders. An evergreen shrub, ephedra (usually Ephedra sinica) over the centuries has traditionally been dried as a whole herb and then added in very small amounts to a tea, along with other herbs, to help ease congestion. Preparations made from two other species, E. intermedia and E. equisetina, have also been used in Traditional medicine, but generally have a less potent therapeutic effect. Traditional East Asian herbal medicines containing ephedra were generally herbal combination formulas designed for specific short-term usage. These would be used in illness conditions where the action of ephedra would counteract certain types of unhealthy symptoms.
While ephedra helps lessen congestion by dilating (opening up) bronchial and nasal passages, it also speeds up the heart rate, raises blood pressure, and has a Diuretic effect. These and many other medicinal actions are the result of its seven active compounds (called alkaloids). Two in particular–ephedrine and pseudoephedrine–are powerful stimulants. They're stronger than caffeine but weaker than amphetamines or the Hormone epinephrine (adrenaline), which the body releases in anticipation of a stressful situation (the "fight-or-flight" response).
In fact, many over-the-counter and some prescription medicines for treating allergies, nasal congestion, asthma, and other upper respiratory symptoms contain laboratory-synthesized ephedra alkaloids, specifically ephedrine and pseudoephedrine. Products containing these synthetic substances are sold (and regulated) as drugs in the United States
However the use of ephedra has become quite controversial because high doses of the herb have been linked to serious health problems, including heart attack, stroke, and even death. This has happened because consumers have misused (or been misled about) dietary supplements containing concentrated forms of this herb. This has happened primarily with products aimed at reducing weight, enhancing athletic performance, and boosting energy. Some healthy young adults (including trained athletes) who took high doses, even for a short time, have become seriously ill, and a few have died.
While some people experience no side effects at all, research indicates that enough people have serious enough reactions to warrant public health regulations. An increased heart rate is common, for instance, even at recommended doses. Also common, especially at higher than recommended doses, or if ephedra is taken for long periods, are such reactions as nervousness and insomnia. Other dangerous reactions include high blood pressure, stroke, and seizures. Sudden death has occurred as well. Among the less common side effects are dizziness, loss of appetite, nausea and vomiting, muscle cramps, tingling, headache, kidney stones, and difficult or painful urination.
By early 2003, adverse effects from the herb had caused enough concern that top U.S. health officials began warning consumers about their risks. The FDA initiated a new program to analyze herbal ephedra supplements to confirm that they contain only natural ingredients, not the chemically synthesized ephedrine alkaloids that are regulated as drugs. Dozens of manufacturers received warning letters from the Food and Drug Administration (FDA) telling them to revise their product labels, striking any unsubstantiated claims regarding ephedra's ability to boost weight loss or improve athletic performance.
Finally, based on the accumulating evidence of the risks of these products, the US FDA banned the sale of ephedra-containing products in December 2003. It is important to note that adverse reactions and concerns about ephedra have related primarily to its sale as an unregulated, poorly labeled dietary supplement, not to its use as a regulated drug. Botanicals such as ephedra are considered dietary supplements. The ban of ephedra was the first such supplement ban by the US government since the passage of a 1994 dietary supplement law that limited government actions against supplements to stopping false labeling claims and to removing supplements with proven safety concerns.
This action against ephedra was similar to the action that the FDA took against a synthetic drug, phenypropanolamine (PPA) that was once considered useful in over-the counter weight loss and nasal Decongestant products. Eventually evidence accumulated of the risk of stroke in users of PPA. In November 2000, the FDA required manufacturers to cease using PPA in both OTC and prescription drug products.
dried herb/tea
General Interaction
An ephedrine overdose can result from taking ephedra along with over-the-counter cold remedies or other medications containing ephedrine or pseudoephedrine.
Because the body is affected in similar ways, ephedra can cause very serious problems when combined with other nervous system stimulants, including herbal ones. These include caffeine and other herbal stimulants, such as yerba mate, kola nut, guarana, or even black tea.
Ephedra interacts with numerous medications, including prescription drugs for heart disease and high blood pressure (such as diuretics), and various drugs used in hospitals, such as the anesthetic halothane or oxytocin (used to treat uterine bleeding).
Ephedra interacts with MAO inhibitors taken for the treatment of depression; seriously high blood pressure, headache, and elevated body temperature can result.
Much remains to be learned about the health risks associated with ephedra, particularly when the herb is taken in doses higher or longer than those traditionally recommended.
While some people experience no side effects at all, research indicates that enough people have serious enough reactions to warrant public health cautions. An increased heart rate is common, for instance, even at recommended doses. Also common, especially at higher than recommended doses, or if ephedra is taken for long periods, are such reactions as nervousness and insomnia.
Other dangerous reactions include high blood pressure, stroke, and seizures. Sudden death has occurred as well. Among the less common side effects are dizziness, loss of appetite, nausea and vomiting, muscle cramps, tingling, headache, kidney stones, and difficult or painful urination.
Even at recommended doses, complications can occur. Too much can cause serious adverse reactions.
Ephedra can make blood sugar levels rise
Ephedra could trigger early labor if taken during pregnacy
Tolerance to ephedra-containing products can develop, meaning that over time, one's body starts to require higher doses to produce the same effect.
Ephedra can dangerously elevate blood pressure, increase chest pain, and interfere with heartbeat rhythm, rate and force, even if you are under medication treatment for high blood pressure, heart disease or a heart rhythm disorder. Even with the ephedra ban, read product packaging carefully. Ephedra may masquerade on labels as epitonin, joint fir, sea grape, desert tea, popotillo, herbal ecstasy, teamster's tea, yellow astringent, and yellow horse.
Don't take ephedra; there are safer self-care options, and there are effective prescription drugs for the medical conditions for which ephedra was traditionally used.

Arthur Moyse: Artist, Critic and Bus Conductor
Bruce Wilkinson writes:
When Dave Cunliffe moved to London in the late-1950s he befriended 'artist, critic and bus conductor' Arthur Moyse who introduced him to anarchist ideology through political debates at Hyde Park Corner and via Freedom newspaper (to which he contributed cartoons and reviews), press and bookshop.
Dave Cunliffe Collection, The University of Manchester Library
A well-known character in radical London and friends with the likes of musician and writer George Melly, Moyse remained proud of his working-class roots and had little time for the kind of artists he often mixed with in London's galleries, taking great pleasure in satirising their lifestyles in his writing and drawings.
A rambunctious drinker, he could often be seen (and even more frequently heard) around the capital's pubs, always prepared to argue the case even if there wasn't necessarily one to contend.
Moyse was no bar-room philosopher though; he was a highly principled Irish immigrant prepared to get physically involved if the cause called for it, fighting street battles with Oswald Mosley's fascists and on behalf of gay colleagues at London Transport and it was his brand of pragmatic anarchism which had a profound impact upon the young Cunliffe, inspiring independent thought alongside a new spirit of literary endeavour.
One of the great treasures within the Dave Cunliffe archive is his correspondence with Arthur Moyse which includes lots of original artwork and cuttings of his column and cartoons from Freedom. Moyse enjoyed sending postcards, Christmas and birthday cards which he would amend by creating collages, satirising the original cover picture. He also sent numerous prints and photocopies of his own drawings which he turned into originals by adding colour or new content altering their initial meanings.
His pictures are mostly humorous black and white ink drawings but with a serious intent, based around a variety of political themes related to his anarchist principles: republican, anti-state and anti-authority, he enjoyed puncturing the pretensions of the privileged middle-classes and the establishment. There's often many different references within each drawing, usually topical and almost always political but also using his self-taught but broad art history knowledge.
Moyse's dispatches are often hilarious tales of his own drunken exploits or contain scandalous gossip about political activists, writers or artists. There is also a whole subsection of spoof letters stretching over thirty years, all beginning "You don't know me, but…" and going on to recount extraordinary tales usually ending with threats of violence or court action under a variety of wry noms de plume.
Much of the correspondence isn't easy to work with as it is often typed on the reverse of arts press releases or gallery invites he received as a critic or even on the backs of letters he'd taken delivery of, re-using the paper with un-numbered pages making it even harder to piece missives together. This does, though, mean that there's lots of interesting information attached and I can confirm that it is easy to get distracted by reading the details of 1980s events at the Riverside Studios or the ICA.
On his return to Lancashire, Cunliffe used Arthur's artwork and articles in Poetmeat and for a number of BB Books editions, Moyse contributing to Global Tapestry until the late-1990s when his health began to deteriorate. BB Books published two works created by Arthur Moyse – Golden Convolvulus – a sex-themed anthology of art and verse which led to Dave Cunliffe's obscenity trial (which we'll deal with fully in a later blog) – and a collection of his own material in the extravagantly titled Wildly Flowering, Sinisterly Creeping, Joyously Twining, Beautiful Terrible Garden World (1968).
He also had his own entirely fictitious Zero One magazine for which he produced a series of front covers often receiving subscription demands both from those interested in reading it and from institutions like the British Library wanting to add issues to its collection. I have to admit wasting quite a bit of research time trying to track down copies before I realised that Zero One didn't actually exist, something I suspect Moyse would have enjoyed.
When Arthur passed away in 2003 his will was contested by distant relatives on the basis that signatures on the document were forged and it is feared that his own huge archive of material has all but disappeared, meaning that this collection of his art, correspondence and writing may well be the most substantial in existence. Although he received an obituary in the Guardian and is fondly remembered by those who still remain from his London circle, Moyse is yet to get the attention he deserves but hopefully someone will make a detailed study of his life and work in the not too distant future.

Articles > Kidney problems in cats and dogs Last update: 10 October 2017
Kidney problems in cats and dogs
Kidney problems are very common among cats and dogs. A large number of these pets only develop symptoms later in life. However, serious kidney problems may also occur amongst younger animals. One can distinguish between acute kidney failure and chronic kidney failure.
The causes of kidney disease amongst cats and dogs
Although the cause of a kidney disease is often unknown, this is not always the case. For instance, among cats there is a hereditary factor that may be relevant. You can think of PKD, or Polycystic Kidney Disease, among Persians. With dogs, renal insufficiency can be seen with a Leishmania infection or, for example, after grape/raisin intoxication.
Symptoms of kidney disease among pets
Chronic kidney disease often lurks for some time before the cat or dog gets any clinical symptoms. It is only when over 70% of the total kidney functionality is lost, that toxins accumulate in the body. Usually, the kidneys filter the blood from these toxins. However, when kidney function is impaired, this is not possible. The animal thereby poisons itself, so to speak. Commonly seen complaints include: reduced to absent appetite, vomiting, drinking a lot/lots of urine, losing weight, dull coat and mucous membrane lesions.
How to diagnose a kidney disease?
The diagnosis is made by means of urine and blood tests. Sometimes additional tests, such as an ultrasound or even a kidney biopsy, are recommended.
Treatment of kidney disease among cats and dogs
Severely damaged kidney tissue cannot recover. The treatment is intended to preserve the tissue that is still functioning. In the critical phase, IV treatment may occasionally be necessary. At a later stage, treatment is continued with a special kidney diet, sometimes complemented with medication or supplements. Generally, these are given for a lifetime.
Kidney diet as part of treatment
A kidney diet generally contains a reduced amount of protein, which is of high quality, to unburden the kidneys. The amount of sodium and phosphorus is also reduced. Kidney disease may be accompanied with nausea, which often makes it difficult to find a palatable kidney diet for your cat or dog. Sometimes it can help to alternate between several types of kidney diets, or to combine the kibble with wet food. Additionally, the palatability (of wet food in particular) can be increased by adding some warm water or by slightly heating the food. Within our product range, you will find excellent food for dogs/cats with kidney disease, including Royal Canin Renal, Hill's k/d, SPECIFIC Heart & Kidney Support, SANIMED Renal and TROVET Renal & Oxalate.
h3]Snacks appropriate for cats and dogs with kidney disease[/h3]
When an animal is prescribed a certain diet, it is essential not to give it a 'regular' diet. Nevertheless, it would be nice to spoil your cat or dog with a treat once in a while. Fortunately, snacks are also available for animals with kidney disease, so they can be spoiled without any problems! A number of examples of responsible snacks can be found amongst other things the assortment of Trovet: For dogs there are TROVET Multi Purpose Treats MRT (Rabbit), TROVET Multi Purpose Treats MLT (Lamb), TROVET Multi Purpose Treats MHT (Hydrolysed Protein) and TROVET Low Calorie Treats LCT (Lamb). Cats can be spoiled with TROVET Multi Purpose Treats MFT (Fish).
Phosphate bonds to support the kidneys
Some kidney patients have an excess of phosphate in their blood. Therefore phosphate bonds can be given to normalize the phosphate levels in the blood. Phosphate reduction slows the further deterioration of the kidneys. Products that contain phosphate binders are: purl=382]Ipakitin[/purl] and Pronefra. For cats the Porus One has been specifically developed. This product captures toxins in the intestine that are harmful to the kidneys, the so-called uremic toxins. Pronefra also has this property, in addition to binding phosphate.
Supportive supplements in case of kidney disease
In addition to the above-mentioned adjustments, there are a number of supplements that can support the kidneys in a natural way. Think of products like Pure Kidney, Phytonics Kidney Comp, De Groene Os Blaas-Nier Compositum and Sensipharm Kidney Care Plus.

It's all about the Coding
Petter Måhlén's Blog
« Share Code Selectively
Code Sharing: Use Scrum »
Code Sharing: Use Git
(This is item 2 in the code sharing cookbook)
Joel Spolsky used what seems to be his last blog post to talk about Git and Mercurial. I like his description of their main benefit as being that they track changes rather than revisions, and like him, I don't particularly like the classification of them as distributed version control systems. As I've mentioned before, the 'distributed' bit isn't what makes them great. In this post, I'll try to explain why I think that Git is a great VCS, especially for sharing code between multiple teams – I've never used Mercurial, so I can't have any opinions on it. I will use SVN as the counter-example of an older version control system, but I think that in most of the places where I mention SVN, it could be replaced by any other 'centralised' VCS.
The by far biggest reason to use Git when sharing code is its support for branching and merging. The main issue at work here is the conflict between two needs: teams need to have complete control of their code and environments in order to be effective in developing their features, and the overall need to detect and resolve conflicting changes as quickly as possible. I'll probably have to explain a little more clearly what I mean by that.
Assume that Team Red and Team Blue are both working on the same shared library. If they push their changes to the exact same central location, they are likely to interfere with each other. Builds will break, bugs will be introduced in parts of the code supposedly not touched, larger changes may be impossible to make and there will be schedule conflicts – what if Team Blue commits a large and broken change the day before Team Red is going to release? So you clearly want to isolate teams from each other.
On the other hand, the longer the two teams' changes are isolated, the harder it is to find and resolve conflicting changes. Both volume of change and calendar time are important here. If the volume of changes made in isolation is large and the code doesn't work after a merge, the volume of code to search in order to figure out the problem is large. This of course makes it a lot harder to figure out where the problem is and how to solve it. On top of that, if a large volume of code has been changed since the last merge, the risk that a lot of code has been built on top of a faulty foundation is higher, which means that you may have wasted a lot of effort on something you'll need to rewrite.
To explain how long calendar time periods between merges are a problem, imagine that it takes maybe a couple of months before a conflict between changes is detected. At this time, the persons who were making the conflicting changes may no longer remember exactly how the features were supposed to work, so resolving the conflicts will be more complicated. In some cases, they may be working in a totally different team or even have left the company. If the code is complicated, the time when you want to detect and fix the problem is right when you're in the middle of making the change, not even a week or two afterwards. Branches represent risk and untestable potential errors.
So there is a spectrum between zero isolation and total isolation, and it is clear that the extremes are not where you want to be. That's very normal and means you have a curve looking something like this:
You have a cost due to team interference that is high with no isolation and is reduced by introducing isolation, and you have a corresponding cost due to the isolation itself that goes up as you isolate teams more. Obviously the exact shape of the curves is different in different situations, but in general you want to be at some point between the extremes, close to the optimum, where teams are isolated enough for comfort, yet merges happen soon enough to not allow the conflict troubles to grow too large.
So how does all that relate to Git? Well, Git enables you to fine-tune your processes on the X axis in this diagram by making merges so cheap that you can do them as often as you like, and through its various features that make it easier to deal with multiple branches (cherry-picking, the ability to identify whether or not a particular commit has gone into a branch, etc.). With SVN, for instance, the costs incurred by frequent merges are prohibitive, partly because making a single merge is harder than with Git, but probably even more because SVN can only tell that there is a difference between two branches, not where the difference comes from. This means that you cannot easily do intermediate merges, where you update a story branch with changes made on the more stable master branch in order to reduce the time and volume of change between merges.
At every SVN merge, you have to go through all the differences between the branches, whereas Git's commit history for each branch allows you to remember choices you made about certain changes, greatly simplifying each merge. So during the second merge, at commit number 5 in the master branch, you'll only need to figure out how to deal with (non-conflicting) changes in commits 4 and 5, and during the final merge, you only need to worry about commits 6 and 7. In all, this means that with SVN, you're forced closer to the 'total isolation' extreme than you would probably want to be.
Working with Git has actually totally changed the way I think about branches – I used to say something along the lines of 'only branch in extreme situations'. Now I think having branches is a good, normal state of being. But the old fears about branching are not entirely invalidated by Git. You still need to be very disciplined about how you use branches, and for me, the main reason is that you want to be able to quickly detect conflicts between them. So I think that branches should be short-lived, and if that isn't feasible, that relatively frequent intermediate merges should be done. At Shopzilla, we've evolved a de facto branching policy over a year of using Git, and it seems to work quite well:
Shared code with a low rate of change: a single master branch. Changes to these libraries and services are rare enough that two teams almost never make them at the same time. When they do, the second team that needs to make changes to a new release of the library creates a story branch and the two teams coordinate about how to handle merging and releasing.
Shared code with a high rate of change: semi-permanent team-specific branches and one team has the task of coordinating releases. The teams that work on their different stories/features merge their code with the latest 'master' version and tell the release team which commits to pick up. The release team does the merge and update of the release branch and both teams do regression QA on the final code before release. This happens every week for our biggest site.
Team-specific code: the practice in each team varies but I believe most teams follow similar processes. In my team, we have two permanent branches that interleave frequently: release and master, and more short-lived branches that we create on an ad-hoc basis. We do almost all of our work on the master branch. When we're starting to prepare a release (typically every 2-3 weeks or so), we split off the release branch and do the final work on the stories to be released there. Work on stories that didn't make it into the release goes onto the master branch as usual. It is common that we have stories that we put on story-specific branches, when we don't believe that they will make it into the next planned release and thus shouldn't be on master.
The diagram above shows a pretty typical state of branches for our team. Starting from the left, the work has been done on the master branch. We then split off the release branch and finalise a release there. The build that goes live will be the last one before merging release back into master. In the mean time, we started some new work on the master branch, plus two stories that we know or believe we won't be able to finish before the next release, so they live in separate branches. For Story A, we wanted to update it with changes made on the release and master branch, so we merged them into Story A shortly before it was finished. At the time the snapshot is taken, we've started preparing the next release and the Story A branch has been deleted as it has been merged back into master and is no longer in use. This means that we only have three branches pointing to commits as indicated by the blueish markers.
This blog post is now far longer than I had anticipated, so I'm going to have to cut the next two advantages of Git shorter than I had planned. Maybe I'll get back to them later. For now, suffice it to say that Git allows you to do great magic in order to fix mistakes that you make and even extracting and combining code from different repositories with full history. I remember watching Linus Torvalds' Tech Talk about Git and that he said that the performance of Git was such that it led to a quantum change in how he worked. For me working with Git has also led to a radical shift in how I work and how I look at code management, but it's not actually the performance that is the main thing, it is the whole conceptual model with tracking commits that makes branching and merging so easy that has led to the shift for me. That Git is also a thousand times (that may not be strictly true…) faster than SVN is of course not a bad thing either.
Code Sharing, Git

The branching is probably the biggest issue for teams migrating from subversion. The conceptual hurdle to overcome that merges are not a herculean task to be avoided at all costs is great.
Thanks for the great post, BTW. It's really interesting to see how tools drive things like branching strategies.

that is potent storm going off over the cotswolds right now - can see it building from oxford.
yeah it really is beautiful. wish i could timelapse the sunset but not enough charge on the camera.
The main storm in EA looks like a supercell now Anyone chasing it?
http://www.meteociel.fr/observations-meteo/satellite.php?region=uk&mode=animation-visible-france This is what I've been using recently (EUMETSAT). Images are much clearer than sat24 but updates less frequently.
i was thinking the same. CAPE modelled in the area of the showers is in the region of 300-500J/kg right now, increasing overnight. The metoffice had a shortwave running up through bournemouth, the midlands and northern england around midnight. Not sure if that's still the case now, but some of the short range models are supporting this. I'm waiting on the next fax update.

Q: Is there a limit of vertices in WebGL? Three.js says that it can't load more than 65k vertices.
In my pure webgl application, it doesn't say anything, but it doesn't show the entire object when I try big objects.
I could split my objects into smaller buffers, but it would make me sad.
Is there any better solution? Is 65k really the limit amount of vertices?

A: Because i can't comment on Giles i put this comment here:
OES_element_index_uint has been added to 'Community approved WebGL Extensions'!!
The extension is already enabled in chrome canary.
http://www.khronos.org/registry/webgl/extensions/OES_element_index_uint/

A: You can draw vertices using either drawElements (which traverses an array of indices into an array of vertices) or drawArrays, which traverses an array of vertices directly.
There doesn't seem to be any limit on the number of vertices in an attribute buffer when you use drawArrays.  Using drawArrays is possibly less desirable because for a typical mesh you have to specify each vertex every time it appears in a primitive.  On the other hand, depending on your scene, this may be an easy way of reducing the number of WebGL calls.
I mention this only because after reading this question and its accepted answer I assumed for a long time that the number of vertices in a drawArrays was also limited to 65K.  By accident I discovered it wasn't, and ended up getting a large speedup by aggregating objects with common materials into single vertex arrays (thus getting around the per-buffer performance overheads that seem to currently burden ANGLE implementations).

A: Yes, WebGL's vertex index buffers are limited to 16-bit right now.  This is because they're aiming to make version 1.0 as cross-platform as possible, so there's a tendency to make stuff target the lowest common denominator -- in cases like this, mobile platforms with limited graphics hardware.
Once 1.0 is out and the initial rush is over, they're likely to loosen these constraints with the help of extensions -- an app will be able to ask whether a given extension is supported by the implementation, and make use of it if it is -- just like in regular desktop OpenGL.  There are already a few extensions available, but again they've only allowed ones with very broad hardware support, so nothing that would help you increase your vertex count.  However, once they loosen the cross-platform requirement, they are likely to support something like the GL_OES_element_index_uint extension that allows 32-bit vertex indices.
You can read some discussion of these issues on the Public WebGL mailing list.

A: A decade passed by and WebGL2 is now pretty universal since the recent Safari 15. WebGL2 provides the required information:
gl.getParameter(GL.MAX_ELEMENT_INDEX)
gl.getParameter(GL.MAX_ELEMENTS_VERTICES)
gl.getParameter(GL.MAX_ELEMENTS_INDICES)

And a lot more constraints and other data, see here[MDN]

A: Generally the other answers are correct, but I figured I would add a bit of clarification:
The only data types accepted by WebGL (and OpenGL ES 2.0) for indices are unsigned bytes and unsigned shorts. Since an unsigned short has a range of 0-65535, this means that if you are using gl.DrawElements (which most frameworks do) you can only reference 65k vertices per draw call. This is almost certainly where the three.js restriction comes from. Please note that you can have a lot more than 65k triangles in one draw call, as long as they only share 65k verts.
If you use non-indexed geometry (gl.DrawArrays), you can have a lot more vertices per-call, but bear in mind that almost always have to repeat some of them. I think in most cases the reduction in GPU memory usage will justify splitting up the draw calls.

A: For the moment being, what you can do is to divide your big object in several segments of 65K elements each and re-index every segment so all the segments have indexes from 0 to 65K. I have tested it and WebGL allows it.
Now, you will have to workout those vertices that are shared among segments. In that case the simplest alternative is to duplicate that vertex so there are not shared vertices anymore. But there are more memory friendly alternatives.
I have a small demo of this working (brain model with approx 350K vertices divided in 5 segments) http://youtu.be/AXZiNHkMpZs#t=2m33s
I hope it helps ;-)

A: As far as I know, this is usually limited by the hardware and/or driver software (hardware is using 16-bit indices or such). Maybe Three.js just plays it safe and tries to makes sure your webgl-app works on all cards. Probably the best way is to break your models down into smaller chunks, this will make sure your app supports most if not all GPUs in use today.

*

*Using immediatemode (glBegin...glEnd), there is no restriction in the amount of vertices   you can push through, but it's going to be slow with that many vertices.

*You could try using glGetIntegerv() with GL_INDEX_BITS, GL_MAX_ELEMENTS_VERTICES and GL_MAX_ELEMENTS_INDICES to query the amount of index bits, maximum vertices and maximum indices the card/driver supports.

*If I remember correctly, Vertex Arrays and VBOs (Vertex Buffer Object) both have similar limits (on the same card/driver), so switching between them probably won't help (not 100% sure on this)

The muon is one of Nature's fundamental particles. Its discovery in 1937 by Carl Anderson marked a radical departure in physicists' understanding of the building blocks of matter. Although it was first assigned a place in theory of nuclear forces which was incorrect, it is now understood to be an important member of the lepton family of particles. TeachSpin, in collaboration with Thomas Coan and Jingbo Ye of Southern Methodist University, has made the first commercial teaching instrument for students to determine some of its physical characteristics.
The muon is produced copiously in Earth's atmosphere by interactions between cosmic rays and atmospheric air molecules, and its flux at sea level is sufficient for student investigations. The muon's lifetime can be measured with our apparatus using experimental techniques common to nuclear and particle physics. The stopping rate of muons, as a function of depth in the atmosphere, can be used as a demonstration of the time dilation effect of special relativity. Since the decay times of individual radioactive particles are randomly distributed, they are a convenient source of genuinely random numbers. These can be used to demonstrate common probability distributions.
With this new TeachSpin Apparatus You Can:
Measure Sea-level Muon Charge Ratio
Raw Data Accessible for Student Analysis
Detailed technical information and a copy of the user's manual for Muon Physics can be found at www.matphys.com.The website is maintained by Professors Thomas Coan and Jingbo Ye of Southern Methodist University, with whom TeachSpin collaborated in developing this exciting apparatus.
The complete instrument has three hardware components: a detector, readout electronics and user-supplied personal computer (PC). Control and data acquisition software are also included.
Detector Module
A 16.5 cm diameter by 36 cm tall black anodized aluminum cylinder houses the entire detector module including the plastic scintillator, photomultiplier tube (PMT), and high voltage supply (HV) as well as electronics for an imbedded light emitting diode (LED). The scintillator, a right circular cylinder, is optically coupled to a single 5 cm diameter 10-stage PMT. Because all of the circuitry for the PMT is mounted inside the aluminum cylinder, there are no exposed HV electrodes. The HV is manually controlled and monitored by external controls. The thickness of the scintillator assures that either muon passage through or decay within the scintillator produces a quantity of light well above the PMT threshold. The imbedded LED can be driven by the adjustable pulser to mimic muon decays and to test the readout electronics. Inside the aluminum cylinder, light tight wrapping on both the scintillator and PMT prevent light leaks.
Block Diagram for Muon Hardware
Electronics Module
The electronics module houses all electronics needed to run the experiment. Connections on the front panel allow students not only to examine the PMT signal itself, but also to monitor that signal as it moves along the readout chain.
PMT pulses are first amplified and compared against an adjustable threshold. Pulses above threshold are sent to timing circuitry implemented in a field programmable gate array (FPGA) chip. The first flash of the scintillator starts the timing system. If a second flash occurs within 20 microseconds of the first, the readout electronics measures the time between the two flashes and passes that time to the lifetime display software.
If no second flash occurs within 20 microseconds, the pulse is simply recorded as a charged particle that has passed through the detector. Communication circuitry transfers the data to a PC or laptop through either a serial or USB port.
Data acquisition of muon decay times is computer controlled to eliminate the tedium of recording numbers and to permit extended data collection times. The decay time histogram is automatically updated with data from the readout electronics. Important display features like the histogram bin size and the logarithmic/linear axis type remain under user control. A password-protected built-in curve fitting algorithm allows for easy determination of the muon lifetime while still maintaining instructor control. Various rate monitors indicate quantities like the instantaneous and time averaged trigger rate, the total number of recorded muon decays and the elapsed time for data acquisition.
Raw data are written to disk files in a compact format so that students can export them to their own software package and not rely on the one provided. Simulation software allows the creation of decay time distributions with a user-adjustable muon lifetime. Source code for data acquisition, plotting and simulation is written in the Tcl/Tk scripting language and is provided free of charge so motivated students can modify the user interface or the built-in lifetime curve fitting algorithm.
The software is distributed on a CD and runs under Microsoft and Linux operating systems. The program requires 100 Mbytes of disc space and 32 Mbytes of memory. It was written to work well with an Intel 133 Mbyte processor. Free updates are available.

Mean Muon Lifetime
Straightforward determinations of average muon lifetime can be made using the curve fitting software provided. More advanced students can be asked to create their own curve fitting algorithms.
Finding the Muon Lifetime
The form for the decay time distribution for muons stopped in the scintillator is characteristic of the decay of radioactive substances with some background counts.
Additional background counts can be easily induced by bringing a 1 micro-Curie Cs-137 source close to the detector. After measuring and plotting the distribution of times between successive scintillator flashes, students can fit the exponential-like distribution and extract the mean muon lifetime (t) in matter, using either our curve fitting algorithm or their own. (The data can be exported to third-party software.) The figure below is a screen capture from the included software and shows a fit to actual student data. Note that the central value for the muon's lifetime is less than the free space value t = 2.197 ± 0.001 µsec. This correctly indicates the effect of nuclear interactions between protons and negative muons.
Once the muon lifetime is measured, a value of the Fermi coupling constant GF, characterizing the strength of the weak interactions, is easily determined from the relation:
Accounting only for statistical error, the student data shown in this brochure yields
GF = (1.18 ± 0.01) x 10–5 GeV–2, which is consistent with more precise measurements.
Sea-level Charge Ratio
With this instrument, the muon lifetime measured in matter (i.e., plastic scintillator) is an average over negatively and positively charged muons. Negatively charged muons have nuclear interactions that slightly lessen their mean lifetime in matter. Therefore, using the lifetime of negative muons in carbon taken from the literature (tau = 2.043 ± 0.003 µsec), the sea-level charge ratio of positive to negative muons at low energy , Eµ = 200 MeV, can be easily determined. The student data included in this brochure yields a sea-level charge ratio f+/f– = 1.08 ± 0.01 (32.5° latitude), which is consistent with published values.
Time Dilation Effect of Special Relativity
Once the muon lifetime is measured, the stopping rate as a function of elevation above sea level can be used to distinguish between the predictions of classical mechanics and special relativity, providing evidence for the time dilation effect of special relativity. Although the instrument is not optimized for this measurement, the simplicity of the measurement is appealing since it requires no lead shielding. For example, after measuring the muon stopping rate to a statistical precision of 2% at two locations vertically separated by 1985 meters, the ratio of these stopping rates (0.55 ± 0.02) agrees well with a straightforward calculation (0.56 ± 0.05) that accounts for time dilation, muon energy loss in the atmosphere and the differential muon momentum spectrum at sea level.
Predictions of Probability Theory
The decay times of individual muons are an excellent source of genuinely random numbers. Once the exponential form of the probability distribution for these times is measured, students can make predictions about the outcomes of corresponding binomial experiments. Taking a new data set then allows a direct comparison between actual data and the predictions of probability theory.
Cosmic Ray Background Radiation
Included rate monitors measure both the stopping rate of muons and the combined total charged particle flux (which includes both muons and electrons) that pass through the scintillator. This data can be used to monitor variations in cosmic radiation at the geographic location of the observer.
Explore Processing of Photomultiplier Signal
Probe points are provided along the entire electronic signal chain so that students can examine the waveforms of the photomultiplier signal, either real or simulated, at various stages of processing. The photomultiplier high voltage, the amplifier gain, the threshold setting and the FPGA timing characteristics are easily measured with an oscilloscope or voltmeter.

SNEAK PREVIEW // STEPFRIENDS – ALL WE'VE GOT
Alex Atkinson October 18, 2014
EXCLUSIVES0 Comments 0
You know you're starting to become an old codger when you've lived through three emo waves, albeit very different in substance. There was the 1985 DC scene, where Ian Mackaye of Minor Threat and Guy Piccioto ventured beyond the current hardcore punk movements to explore a more melodious and cathartic sound in Embrace and Rites Of Spring, respectively. Then there was, of course, the emo wave of the early 2000's, which emerged from a hairy mole on the tank-ass of 'metalcore'. It almost felt like this 'emo' movement was a palatable solution to the outright verbal aggression of hardcore at the time; it was the mixing of uber-clean pop vocals, with the occasional hardcore squeal that made bands like The Used and My Chemical Romance so appealing to distraught and unhappy teenagers. The second revival of emo appeared almost as homage to the small emo scene of the mid-90's, which included bands like Sunny Day Real Estate, The Promise Ring, Braid and American Football. The Word Is A Beautiful Place And I Am Not Afraid To Die, Empire! Empire! I Was A Lonely Estate, Into It Over It and A Great Big Pile Of Leaves are key examples here. To be honest, it has never really been my thing. I just couldn't find that gripping moment amidst the pathos, catharsis and, at least in the 2000's, the eyeliner.
This is why I find myself in a difficult situation. Syracuse's Stepfriends have kind of won me over with their spellbinding mix of emo, indie and folk. 'Quiet Place', currently streaming via bandcamp, is truly infectious; its compelling vocal harmonies are almost impossible to wash off. Listeners will no doubt find echoes of Saves The Day and The Get Up Kids, and many subtle math rock and jazz sensibilities are also likely to be picked out.
We're happy to bring you two wonderful tracks from Stepfriends' upcoming album All We've Got: 'Quiet Place' and 'Renovation'. It is a truly catchy album and one that we needed to share with you pronto. Get them in yer ear 'oles and prepare for this bound-to-be-amazing debut.
All We Got will be available digitally from the 21st of October. Pre-orders for vinyl (due early December) are available here.

Cold war of words? Political voices on Ukraine
The escalating crisis in Crimea has set a number of western powers against Russia in a battle of words that includes threats of "costs" and allegations of illegal behaviour.
Share on WhatsAppSend

Load more share options
Powers such as the US and the UK say that Russia has behaved in an illegal fashion by compromising Ukraine's sovereignty – and Russia has retorted that western powers have supported the establishment of a "right wing" leadership in Ukraine.
Channel 4 News lists the key statements coming out of Kiev, Moscow and Geneva:
Ukraine's acting leadership has said the country is on "the brink of the disaster". It has accused Russia of declaring war on the country, and has called on the "entire global community" to help normalise the situation.
Ukraine's acting president Arseniy Yatsenyuk (above) said on Monday that any attempt by Russia to "grab Crimea" will have no success at all.
Speaking alongside British Foreign Secretary William Hague, Mr Yatsenyuk said: "Those who are today in Crimea, they present an illegal – and I would reiterate again – an illegal power in Crimea.
"They tried to squeeze Ukrainian assets; they try to confiscate Ukrainian property; they try to disarm Ukrainian army.
"For these kind of actions they will be prosecuted under domestic and international law and they have to know this."
He added: "Crimea is the territory of Ukraine. And despite the presence of Russian military, despite the fact Russian military supports an illegal government, we will tackle these problems. And any attempt of Russia to grab Crimea would have no success at all. Give us some time."
Russia argues that it is protecting its "compatriots" and its interests in Crimea – where it has a major naval base at Sevastopol.
It has rejected the acceptance of the new Ukrainian leadership by western powers – a leadership that it says has been taken over by "xenophobic, anti-Semitic, neo-fascist" elements.
Russia's Foreign Minister, Sergei Lavrov (above), said on Monday: "This is a question of defending our citizens and compatriots, and ensuring human rights, especially the right to life.
"Those who are trying to interpret the situation as a sort of aggression, and threatening us with sanctions and boycotts, these are the same partners who have been consistently encouraging the political powers close to them to declare ultimatums and renounce dialogue, which has ultimately polarised Ukrainian society.
"We call upon them to show responsibility, to set aside geopolitical calculations, and to put the interests of the Ukrainian people above all."
Russia's foreign ministry also reacted angrily on Monday to a decision by the G8 group of countries to suspend preparations for a summit, scheduled to be held in the Russian city of Sochi in June, over the crisis in Ukraine.
In a statement it said the decision has "no grounds" and "damages not only the countries of the G8 but also the whole international community".
Barack Obama invited Russia's anger on the weekend when he called for its former Cold War enemy to face "costs".
"Any violation of Ukraine's sovereignty or territorial integrity would be deeply destabilizing, which is not in the interests of Ukraine Russia, or Europe," he said in a White House briefing.
"It would represent a profound interference in matters that must be determined by the Ukrainian people.
"The United States will stand with the international community in affirming that there will be costs for any military intervention in Ukraine."
On Sunday, US Secretary of State John Kerry has criticised Russian actions, saying the country was behaving in a "19th century fashion."
He spoke of "very serious repercussions" for Russia and said G8 nations and some other countries are "prepared to go to the hilt to isolate Russia" with an array of options available.
"They're prepared to put sanctions in place, they're prepared to isolate Russia economically, the rouble is already going down. Russia has major economic challenges," he said.
Kerry listed visa bans, asset freezes, trade isolation, and investment changes as possible steps.
British Foreign Secretary William Hague has echoed US sentiments, saying this "cannot be the way in the 21st century to conduct international affairs."
He said: "Russia should be in no doubt about this. This is something that we take very seriously, we have to take very seriously because if this is, if this becomes the normal way of behaving in the world, of intruding upon and violating the sovereignty of neighbours, well then clearly that would be an even bigger crisis in international affairs."
He added that military options are "not being discussed", but that the UK supported "diplomatic and economic pressure".
Heavily dependent on Russian gas, and politically closer to Moscow than other western nations, Germany said on Monday that it was not too late to resolve the current crisis by political means.
German Chancellor Angela Merkel's spokesman Steffen Seibert urged Moscow to withdraw from the "logic of troop movements".
"There is no doubt President Putin has a completely different view on the situation and events in Crimea from the German government and our Western partners," he said.
Angela Merkel (above), a fluent Russian speaker, spoke to President Putin late on Sunday night, and suggested a "fact-finding mission" to Ukraine, perhaps led by the Organisation for Security and Co-operation in Europe (OSCE). President Putin was said to be "receptive" to this idea.
French Foreign Minister Laurent Fabius called Russia's action in Ukraine "unacceptable".
"It's always kind of the same approach by Russians," he said. "The Russians consider that countries which belonged to their empire at one point or another should not be out of a certain control.
"There, in the Crimea case, they already have a base in Sevastopol and considering what happened in Ukraine – the overthrow, or at least the departure of Yanukovych – they want to get their hands back on Crimea.
"Obviously, as far as international law is concerned, it is unacceptable."
Ban Ki-Moon has urged "calm" as the crisis in Ukraine escalates, and has urged Russia to not escalate the situation.
"I have repeatedly emphasized that it is critical to ensure full respect for and the preservation of Ukraine's independence, unity, sovereignty and territorial integrity," Mr Ban said.
"It is now of utmost importance to restore calm, to de-escalate tensions immediately, through a dialogue."

Q: Using Ptr in OpenCv causes memory exception void hello(Mat original)
{
  Mat a=original.clone();
  Ptr<IplImage> b = &a.operator IplImage();
  return;
}

This function will cause a memory exception. Beause I have to use an old funciton which parameter is IplImage*, I transform the Mat into Ptr and cause memory exception. The above function is just a simplified version.

A: Ptr<T> is a template class thats performs automatic destruction of the wrapped object pointer (see the official documentation for more information about it).
In your code snippet, both a and b are local variables inside the function hello, so they will be destroyed when this function returns and in the reverse order of construction, so a will be destroyed after the destruction of b.
The memory exception could occur because both variables (a and b) refer to the same memory area: in fact, the function Mat::operator IplImage does not copy the underlying data of the Mat object, but creates the IplImage header for these matrix data.
So when the Mat destructor will try to destroy the object a, the portion of memory dedicated to the underlying data will already have been deallocated by b.

A: From OpenCV doc

The operator creates the IplImage header for the matrix without copying the underlying data. You should make sure than the original matrix is not deallocated while the IplImage header is used.

You can pass the reference of the returned header to a function that accepts an IplImage*, likevoid foo(IplImage* img) in the code below):
#include <opencv2\opencv.hpp>
using namespace cv;

void foo(IplImage* img)
{
    // Set to blue
    cvSet(img, Scalar(255,0,0));
}

int main()
{
    // Small green image
    Mat3b img(10, 10, Vec3b(0, 255, 0));

    {
        // Doesn't modify original image
        Mat mat = img.clone();
        IplImage ipl = mat;
        foo(&ipl);

        // ipl and mat are blue now
        // img is still green
    }

    {
        // Modify original image
        IplImage ipl = img;
        foo(&ipl);

        // ipl and img are blue now
    }

    // img is blue

    return 0;
}
