Physical activity promotes changes in the brain that may protect high-risk individuals against cognitive decline, according to a new study. That includes the development of Alzheimer's disease, the world's most common type of dementia and one that needs no introduction.
The new study included both people who carry a high-risk gene for Alzheimer's disease, and other healthy older adults without the gene. Those with the gene were put biologically at greater risk of Alzheimer's, so that begged the question: could exercise held shield even these people from the disease?
The results showed that even if you are at genetic risk for Alzheimer's disease, the benefits of exercise to your brain function might be even greater than for those who do not have that genetic risk. It's another clear indication that we have control over our health-related fate.
While evidence already shows that exercise is linked with maintaining strong cognitive function across a life span, most of this research has been done with healthy people. But it failed to account for those at high risk of Alzheimer's.
Researchers compared brain activation during memory processing in four separate groups of healthy 65- to 85-year-olds. The level of risk was defined by whether an individual carried the apolipoprotein E-epsilon4 (APOE-ϵ4) gene. Physical activity status was defined by how much and how often the participants reported exercising.
The researchers used MRIs to measure brain activation of the participants while they performed a mental task involving discriminating among famous people. This particular test is very useful, as it engages a wide network called the "semantic memory system." Here, 15 different functional regions of the brain are involved.
In the study groups of those carrying the gene, individuals who exercised showed greater brain activity in memory-related regions than those who were sedentary. Also interesting, physically active people with the gene had greater brain activity than those who were physically active but not gene carriers.
It could be that using more areas of the brain may serve in itself as a protective function in the face of Alzheimer's disease.
What all this means is that, even if you are told you are at genetically higher risk of dementia, you can still help yourself. Get at least a half-hour of exercise a day and your mind could stay sharper.


Investments . . . .
Let's talk about investments . . . .
No, not that kind – that's why I hire someone else to manage my meager funds.
But I will admit that I have recently started a subscription to the Wall Street Journal – I remember my dad reading WSJ when I was a kid, so if it was valuable for him, maybe I can benefit, too.
And I always thought of WSJ as primarily a publication about money and investments and financial issues in general. It's in the name, after all: the journal about Wall Street.
But I see much more than that now, and one recent article particularly struck me.
What self-investment have you made recently? Where have you seen that pay off for you, now or in the future? And that's another key: as with financial investing, it is important to have a long-term view and strategy. Don't expect an immediate return; look at how an investment in yourself can provide benefit in the future as well as now, whether the future is a month, a year, five years, or more into the future.
Businesses and organizations need to invest, too. More on that in two weeks – see you then!

Should I use principal components analysis (PCA) or Exploratory Factor Analysis (EFA) for my work? This is a common question that analysts working with multivariate data, such as social scientists, consumer researchers, or engineers, face on a regular basis.
In this post, I share my favorite example for explaining a key difference between PCA and EFA. This distinction opens the door to explaining other important differences and is helpful when figuring out which technique is most appropriate for a given application. Choosing improperly might mean misleading results or incorrect understanding of the data.
Let's start by creating some data that follow a standard normal distribution (a JSL script for all analyses in this post is attached if you want to follow along). Specifically, I create a data table with 1,000 observations on four variables that are uncorrelated with each other.
Figure 1. Correlation coefficients and corresponding heat map for four simulated variables.Now, we can ask ourselves an important question: What would the results look like if I use PCA on these data? And what would the results look like if I use EFA instead? If you're not sure, keep reading.
Let's use the Factor Analysis platform in JMP to perform simultaneously a PCA and an EFA on these data. I'll retain one component/factor only because we have a small number of variables. This also eliminates the need for any rotation.
The component or factor loadings from the analyses are critical to help us understand what the component or factor represents; variables with high loadings (usually defined as .4 in absolute value or higher because this suggests at least 16% of the measured variable variance overlaps with the variance of the factor) are most representative of the component or factor. Below, we can compare the resulting component loadings (displayed first) against the factor loadings (displayed second).
Figure 2. Component and factor loadings from a principal components analysis and exploratory factor analysis on four simulated variables that are uncorrelated.
Figure 3. Heat map of reduced correlation matrix, where unities in the diagonal have been replaced by squared multiple correlations.
Every entry in the reduced correlation matrix, in this example, is very small (nearly zero! The actual values are 0.002, 0.002, 0.004, and 0.001). An eigenvalue decomposition of the full correlation matrix (Figure 1) is done in PCA, yet for EFA, the eigenvalue decomposition is done on the reduced correlation matrix (Figure 3). Differences in the data analyzed help explain differences across analyses, but none of this tells us what the differences mean from a practical point of view….
PCA and EFA have different goals: PCA is a technique for reducing the dimensionality of one's data, whereas EFA is a technique for identifying and measuring variables that cannot be measured directly (i.e., latent variables or factors). Thus, in PCA all of the variance in the data — reflected by the full correlation matrix — is used to attain a solution, and the resulting components are a mix of what the variables intended to measure and other sources of variance such as measurement error (see left panel of Figure 4).
By contrast, in EFA not all of the variance in the data comes from the underlying latent variable (see right panel of Figure 4). This feature is reflected in the EFA algorithm by "reducing" the correlation matrix with the SMC values. This is appropriate because a SMC is the estimate of the variance that the underlying factor(s) explain in a given variable (aka communality). If we carried out EFA with unities in the diagonal, then we would be implicitly saying the factors explain all the variance in the measured variables, and we would be doing PCA rather than EFA.
Figure 4. Graphic comparison of principal components analysis and exploratory factor analysis.
Figure 4 also illustrates another important distinction between PCA and EFA. Note the arrows in PCA are pointing from the measured variables to the principal component, and in EFA it's the other way around. The arrows represent causal relations, such that the variability in measured variables in PCA cause the variance in the principal component. This is in contrast to EFA, where the latent factor is seen as causing the variability and pattern of correlations among measured variables (Marcoulides & Hershberger, 1997).
In the interest of clarity, it's important I outline a few more observations. First, most multivariate data are correlated to some degree, so differences between PCA and EFA don't tend to be as marked as the ones in this example. Second, as the number of variables involved in the analysis grows, results from PCA and EFA become more and more similar. Researchers have argued that analyses with at least 40 variables lead to minor differences (Snook & Gorsuch, 1989). Third, if the communality of measured variables is high (i.e., approaches 1), then the results between PCA and EFA are also similar. Finally, this favorite example of mine relies on using the "Principal Axis" factoring method, but other estimation methods exist for which results would vary. All of these observations must be taken into account when analysts make the choice between EFA and PCA. But perhaps most importantly for psychometricians (those who developed EFA in the first place) is the fact that EFA posits a theory about the variables being analyzed; a theory that dates back to Spearman (1904) and suggests unobserved factors determine what we're able to measure directly.
I list some key points below, but note that an excellent source for continuing to learn about this topic is Widaman (2007).
PCA is useful for reducing the number of variables while retaining the most amount of information in the data, whereas EFA is useful for measuring unobserved (latent), error-free variables.
When variables don't have anything in common, as in the example above, EFA won't find a well-defined underlying factor, but PCA will find a well-defined principal component that explains the maximal amount of variance in the data.
When the goal is to measure an error-free latent variable but PCA is used, the component loadings will most likely be higher than they would've been if EFA was used. This would mislead analysts into thinking they have a well-defined, error-free factor when in fact they have a well-defined component that's an amalgam of all the sources of variance in the data.
When the goal is to get a small subset of variables that retain the most amount of variability in the data but EFA is used, the factor loadings will likely be lower than they would've been if PCA was used. This would mislead analysts into thinking they kept the maximal amount of variance in the data when in fact they kept the variance that's in common across the measured variables.

Laura, I really appreciate that you took the time to explain the difference between these techniques. This was very well written and informative and I loved your use of graphs and diagrams for illustrating your points. Thank you!
The last diagram for comparison of EFA and PCA is very helpful to undrestand. Could you let me know a source, if this is from somewhere else, to use it in my presentation?
I'm glad you found the last diagram helpful. I created that image for this post and am not aware of other sources that have something similar.
Super helpful. In fact, so helpful that I'll be incorporating these ideas into an upcoming grant on coral work!


Stirling Council Archives holds various education records, including a Log Book for Drymen Public School, 1874-1911 (SC5/6/99). The Head Teacher of Drymen Public School was responsible for keeping this log book, which recorded matters such as attendance, staff absences, inspections and prize-givings. Pupil attendance is mentioned frequently. The image below shows entries for April & May 1875 when attendance was often affected by the weather and on one occasion a Village Fair.
Log books do not generally record names of children attending the school unless something of note has occurred. In January 1911, there are entries about a child Maggie Bilsland from Class 3. After the winter break, the School reopened on January 10th, with Maggie in attendance, however, by January 14th Maggie was admitted to Lennox Hospital for Diptheria, where she died on January 19th. The Head Teacher notes that 'the pupils in the Senior Room attended the Funeral and sent a Floral Wreath'.
Sitting within the log book is a certificate from the Medical Officer of Health. This would have been given to Maggie's father, Thomas Bilsland, to show that the house had been disinfected. This was required by the Public Health (Scotland) Act, 1897 when a child was removed to a hospital due to an infectious disease.
In 1911, Maggie was one of 56 admissions to Lennox Hospital for Diptheria, of which eight patients died. All deaths were children under the age of ten. It was not until later in the 1920s that vaccination programmes became widespread.

Astronauts Are Cleaning Up Space Junk With a Giant Harpoon and Net

Tech & Science International Space Station Spacecraft Space Garbage
Just a few days after President Donald Trump signed a directive to clean up space, by pure coincidence U.K. astronauts planned to eject a satellite on a demo mission to see if the spacecraft can roam around Earth's orbit nabbing space garbage.
The new garbage-collecting satellite, called the RemoveDebris, was launched with the aim of circling the Earth and using a harpoon and a net to trap debris. The device was pushed out of the International Space Station on Wednesday with the help of a robotic arm. It is the largest satellite to be deployed from the ISS, BBC News reported.
Early this morning, NanoRacks released the largest satellite to ever be deployed from the @Space_Station. The #RemoveDEBRIS #MicroSat is now in orbit. Thanks to all involved in this exciting program! https://t.co/XbAdu0Rwg7 #ISS #Kaber pic.twitter.com/y5bV9TVHX2
— NanoRacks (@NanoRacks) June 20, 2018
This space junk test is just one of the ideas being considered to get rid of the approximately 7,500 tons of space garbage, like old rocket parts and broken pieces of spacecraft, that is circling the Earth. In January, Chinese scientists wrote a paper describing how they would clean up Earth's cluttered orbit using giant lasers.
Last December, astronauts launched the Space Debris Sensor, a device mounted to the top of the space station, which focuses on catching debris less than a millimeter across. Even though this space trash is smaller than a grain of sand, it is still big enough to wear away at the ISS.
The RemoveDebris satellite is not mounted to anything and doesn't have any lasers. It's meant to be a free agent, orbiting the Earth.
Astronauts had been storing the device on the space station since April. During the first month, ground controllers will monitor the satellite to make sure it is working properly.
For the first round of tests, the satellite will shoot out a piece of debris, which it will then track with a laser and camera. Then it will actually try to grab the object with a net. A small harpoon will be fired to learn more about how such devices move and affect a surface in space.
To avoid turning into a hunk of junk itself, the RemoveDebris will use a membrane to act like a sail, pulling the satellite down to Earth faster than would otherwise be the case.
"Once we know all its systems are behaving properly, only then will we begin our experiments," principal investigator Guglielmo Aglietti from the Surrey Space Center in the U.K. told BBC News.

Setting up robust video conferencing in an SME
Our kit list and setup (after much trial and error)
As a business, we have always loved collaborating in person, whether it's workshops, stand-ups, tech-talks, whiteboard solutionising or just water cooler chat. But like millions of other companies, we've also embraced remote and flexible working, and experimented with a number of video setups along the way. Some of the tools we've tried (not to say they're no good, they just weren't suitable for us):
Highfive (including dedicated meeting room cameras)
In the last year we finally feel like we've nailed it. This is our typical kit list:
Zoom Rooms licence (£400 per room per year): to run Zoom's conferencing functionality
65"/75" TVs: to display video links and screen sharing (we've used the more reasonably priced brand Hisense)
Mini PC: to run the Zoom Rooms software and power the TV display
All-in-one camera/microphone/speaker (AVer VB342): to provide audio and video connection to remote participants
iPad mini and stand: provides access to meeting calendar and control of room settings such as audio levels, camera direction, and screen sharing
Kaptivo for Zoom Rooms (a whiteboard camera we are currently trialling)
While costs are vastly different from any enterprise video setup, we completely appreciate they may still be out of reach for many SMEs. Setting up each Zoom meeting room has cost us around £3,000, including licenses, camera, TVs (we have two side by side in some rooms) and an iPad mini. Costs could be reduced by using one smaller TV and choosing alternative cameras.
Hello Zoom
Zoom Rooms makes it incredibly easy for team members to set up scheduled or impromptu audio and video calls. Using an iPad mini, Zoom represents a big leap forward in terms of reliability and ease-of-use, and with features such as Google Calendar integration it's been simple to embed it into our existing processes.
In the past four months we've 'Zoomified' half of our meeting spaces, and are regularly reviewing how well this serves our needs as the number of people working either partly or fully remotely continues to grow. We're also trialling a portable all-in-one camera (Logitech ConferenceCam Connect), which has enabled people to be remotely involved in client visits, pitches and other off-site events.
The remote ecosystem
While Zoom Rooms has already had a big impact, it of course takes more than a single piece of technology to affect a true shift in the way teams work. At Box UK especially, continuous collaboration and communication are vital to the success of our projects, so we've had to look at how we can support this when face-to-face options are unavailable. (Even more so considering that collaboration and communication topped a list of issues remote workers struggle with in the most recent State of Remote Work report).
Fortunately, there are plenty of (affordable) tools out there that enable knowledge and ideas to be shared and discussed through remote channels. For example, we've long used GSuite to share documents, Confluence to centrally record important information, and Slack to support real-time updates, making it relatively simple to adjust for increased remote working.
A perhaps more overlooked factor in ensuring remote participation is how well it's supported by the wider organisational culture. Alongside collaboration and communication, loneliness was cited as the biggest struggle for remote workers in the State of Remote Work report, and it's important that we're able to offer these team members the same vibrant and open working environment that office-based employees experience.
Dedicated, proactive line management can be key to countering this risk, as it provides a space for remote workers to raise concerns or challenges, and also ensures that they don't lose out on valuable elements of the job such as learning and development. We also strive to make these team members feel included by encouraging remote participation in company-wide meetings and tech talks, and even sending them treats in the post as part of any social reward initiatives.
We're part-way through our journey to facilitate seamless remote working, and it's likely that this will remain ongoing as we seek out further improvements and opportunities. What is clear though is that equipping our business with remote capabilities has had a significant positive impact on productivity, both by enabling us to grow our remote workers, and in response to some unexpected circumstances, including an office refit, recent flooding in the UK, and now the coronavirus.

Q: How to solve Importing issue in wordpress 3.3.2? How can I solve this problem when I ma trying to import posts in wordpress 3.3.2 ??

The export file could not be found at
  /home/pixl/public_html/wp-content/uploads/shutter.xml_.txt. It is
  likely that this was caused by a permissions problem.

Although the permissions for the uploads folder are : 777
!!

A: i found different solution of this problem just install backupwordpressdb plugin and make backup of your wordpress and download that zip file again import that zip file into your next wordpress site and import that zip file.
may be this will solve your problem.

A: Check the permission of your date based folder: uploads/2012/06/ My Wordpress import saves data there.

A: Mine was an isolated use case... but just posting here in case someone else struggles.
The wordpress importer does not play well with the Media Cloud plugin (and I would assume other plugins that modify where uploads are stored).
Disabling the media cloud plugin fixed this problem for me. Try disabling all your plugins and running the importer again (as I should have done... I know better).
Good luck!

Former Broncos wide receiver
Mark Anthony Jackson is a retired American professional football player who was selected by the Denver Broncos in the sixth round of the 1986 NFL Draft. A 5'9", 174 lb wide receiver from Purdue University, Jackson played in the 1984 Peach Bowl before spending nine NFL seasons from 1986 to 1994 for the Broncos, the New York Giants, and the Indianapolis Colts. Jackson played in Super Bowls XXI, XXII, and XXIV with the Broncos. Jackson caught the touchdown pass that sent the game into overtime on "The Drive" in the Broncos' January 11, 1987 AFC Championship Game victory over the Cleveland Browns. Along with Vance Johnson and Ricky Nattiel, Jackson comprised the "Three Amigos" receiving combination in the late 1980s. He lived in Terre Haute, Indiana, during his youth and played for South Vigo High School. [More at Wikipedia]

The Device Address is a number from 0 to 247. Messages sent to address 0 (broadcast messages) can be accepted by all slaves, but numbers 1-247 are addresses of specific devices. With the exception of broadcast messages, a slave device always responds to a MODBUS message so the master knows the message was received.
The Data defines addresses in the device's memory map for read functions, contains data values to be written into the device's memory, or contains other information needed to carry out the function requested. The Error Check is a 16-bit numeric value representing the Cyclic Redundancy Check (CRC). The CRC is generated by the master (via a complex procedure involving ORing and shifting data) and checked by the receiving device. If the CRC values do not match, the device asks for a retransmission of the message. In some systems, a parity check can also be applied.
Below would be a common example of how a vendor might logically map different types of process variable data. Discrete inputs and coils are one-bit values, and each has a specific address. Analog inputs (also called "Input Registers") are stored in 16-bit registers. By utilizing two of these registers MODBUS can support the IEEE 32-bit floating point format. Holding Registers are also 16-bit internal registers that can support floating point.
The literature or operation manuals of most MODBUS compatible devices, such as this TMZ Temperature Transmitter from Moore Industries, publish the addresses of key variables in the MODBUS Memory Map. The TMZ's addresses conform to the MODBUS spec.
Data in the memory map is defined in the MODBUS specification. Assuming that the device vendor followed the MODBUS specification (not all do), all data can easily be accessed by the MODBUS master, which follows the specification. In many cases, the device vendor publishes the memory locations (Figure 3), making it easy for the person programming the master to communicate with the slave device.
Where 5 is the device address, 04 says to read input registers, 2 is the starting address (address 30,002), 3 means to read three contiguous data values starting at address 30,002, and CRC is the error check value for this message.
Where 5 is the device's address; 04 is the repeated read command; aa, bb and cc are the three 16-bit data values; and CRC is the error check value for this message.
Reading and writing digital inputs and outputs is done in a similar manner using different read and write functions.
Assuming that the device follows the MODBUS specification, it is a simple programming task to set up the master to read and write data, check status, obtain diagnostic information and perform various control and monitoring functions.
One of the easiest ways to bring field devices into a process control system, PLC or industrial computer is to simply connect digital and analog I/O into a distributed I/O system that has MODBUS communication capability.
For example, the NCS (NET Concentrator System) from Moore Industries allows a user to connect analog and digital signals remotely, which can then be connected to a MODBUS master via twisted pair cable.
Multiple NCS systems can be installed in several locations throughout the plant, all linked by MODBUS (Figure 4).
Figure 4 – In most plants, field instruments connect to the control system with individual "home run" twisted pairs (below). When the instruments are wired into a distributed I/O system, such as the NCS from Moore Industries (center), more devices can be added, but only a single twisted pair is needed to transmit all the data to the MODBUS master. Multiple NCS systems can be networked (bottom) over the same MODBUS network, so the entire plant can be converted from home run wiring to MODBUS.
This solution works for both new and existing plants. In many existing plants, field instruments typically connect to the DCS or PLC via "home run wiring," where each device is connected with individual twisted pairs that carry analog signals. With the NCS, one of those twisted pairs can be used for the MODBUS signal. This is particularly useful if the plant wants to add additional field instruments, but does not want to run more wiring (at an installed cost of $100 per foot). A distributed I/O system can accommodate all of the existing I/O, or it can be used just to send data from all the new field instruments.
In some cases, the control system is not able to deal with a MODBUS signal. It may be that the legacy control system is accustomed to dealing with 4-20mA analog I/O and directly wired digital I/O, and reprogramming the old system to accommodate MODBUS data would be difficult. Often, users would like to add new remote signals to their system without having to run wire or buy expensive MODBUS interface cards that require extensive re-programming. In that case, a peer-to-peer solution works best.
For example, the CCS (Cable Concentrator System) and the NCS (NET Concentrator System) from Moore Industries both have peer-to-peer communication abilities. The NCS and CCS are similar to a distributed I/O module, but have more built-in intelligence and can be set up in either a peer-to-peer or peer-to-host configuration.
Figure 5 – In some cases, the control system is not able to deal with a MODBUS signal. In that case, a peer-to peer solution with two NCS systems simply replaces all the home run wiring with a single MODBUS cable. Analog outputs from the control room NCS are then wired directly into the host system's I/O card.
With a peer-to-peer NCS system (Figure 5), two concentrators are used: one in the field and one in the control room. Field instruments connect to the remote NCS, which connects to the control room NCS via a single twisted pair wire. Then, outputs from the control room NCS are wired into the control system's existing analog I/O panel. In this way, the analog signals from the new field transmitters can be seen in their original analog state through the plant's existing analog I/O cards. This makes programming and commissioning of the new signals less difficult than programming new digital interface cards.
These peer-to-peer solutions can also accommodate bi-directional communication in which both sides of the system can have inputs and outputs.

Despite improvement, maternal mortality in Haiti remains high at 359/100,000 live births. Improving access to high quality antenatal and postnatal care has been shown to reduce maternal mortality and improve newborn outcomes. Little is known regarding the quality and uptake of antenatal and postnatal care among Haitian women.
Exit interviews were conducted with all pregnant and postpartum women seeking care from large health facilities (n = 10) in the Nord and Nord-Est department and communes of St. Marc, Verrettes, and Petite Rivière in Haiti over the study period (March-April 2015; 3–4 days/facility). Standard questions related to demographics, previous pregnancies, current pregnancy, and services/satisfaction during the visit were asked. Total number of antenatal visits were abstracted from charts of recently delivered women (n = 1141). Provider knowledge assessments were completed by antenatal and postnatal care providers (n = 39). Frequencies were calculated for descriptive variables and multivariable logistic regression was used to explore predictors of receiving 5 out of 10 counseling messages among pregnant women.
Among 894 pregnant women seeking antenatal care, most reported receiving standard clinical service components during their visit (97% were weighed, 80% had fetal heart tones checked), however fewer reported receiving recommended counseling messages (44% counselled on danger signs, 33% on postpartum family planning). Far fewer women were seeking postnatal care (n = 63) and similar service patterns were reported. Forty-three percent of pregnant women report receiving at least 5 out of 10 counseling messages. Pregnant women on a repeat visit and women with greater educational attainment had greater odds of reporting having received 5 out of 10 counseling messages (2nd visit: adjusted odds ratio [aOR] =1.70, 95% confidence interval [CI]: 1.09–2.66; 5+ visit: aOR = 5.44, 95% CI: 2.91–10.16; elementary school certificate: aOR = 2.06, 95% CI: 1.17–3.63; finished secondary school or more aOR = 1.97, 95% CI = 1.05–3.02). Chart reviews indicate 27% of women completed a single antenatal visit and 36% completed the recommended 4 visits.
Antenatal and postnatal care uptake in Haiti is sub-optimal. Despite frequent reports of provision of standard service components, counseling messages are low. Consistent provision of standardized counseling messages with regular provider trainings is recommended to improve quality and uptake of care in Haiti.

nth_element in 4.3.0 fails to meet its complexity requirements.
This is basically intraselect by Dave Musser.
The question is "What algorithm should you switch to when quickselect fails?"
In the codebase __heapselect() is called. But this in O(N * log N). __heapselect() is O(middle-first) + O((last-middle) * log(last-first)) which is O(N * log N) and the C++ standard requires nth_element to be O(N). __heapselect() is no use at all here.
Roger, can you have a look? Thanks in advance.
Steven's benefit, the implementation I've already coded up uses the median-of-medians in groups of five strategy as a fallback to a modified quickselect.
case and changing to an O(n) implementation that has a large co-efficient constant may upset some folks.
Many thanks Roger for your further help on nth_element, excellent news.
So median-of-3 or for large N is a must. And this is run for 3/2 * log2(N) steps.
If it has not converged by end of steps (so it has been a bad run) or new N is < some constant (making binary insertion sort worthwhile) then at that point you want the cheapest approximate median algorithm that is _guaranteed_ O(N). The algorithm is still O(N) as the choosing median and partitioning is occuring in serial. In this case, it is minimising the constant factor that matters.
But this approximate median is less well known.
I have not yet checked median of median-of-5 against this, but I believe (ii) works out cheaper.
And if it works that there exists an even cheaper guranteed O(N) partitioning that finds an approximate median, gcc should use that. It does not matter if the exact median is found each time round just as long as N/2 elements are reduced each time round.
If you wanted the iterator that was 20% in from the start and you sampled elements to choose a partition element, instead of choosing an approximate median, choose the element that is 20%. So if the sample was 5 elements, choose the 2nd element. Now if partitioning was lop-sided but you reduced the number of elements drastically leaving a tiny amount as candidates, you have massively reduced the problem. This is brand new research in nth_element but I have not yet seen much analysis.
used in an implementation to guess a good pivot, but the quality of this median, i.e. how approximate it is, doesn't meet the necessary criterion to ensure an O(N) worst case.  You'd still need a fallback method with guaranteed bounds or an exact median in order to achieve O(N).  i.e. it could help improve the average case performance, but doesn't help with the worst case.
you can eliminate 10% each round, you still achieve O(N) worst-case.
doesn't provide such a constant fraction guarantee.  An analysis shows that at each round, it can only eliminate (2^n-1)/3^n of the elements in its worst case, where n is log_3(N).
By hand, naming the ranks 0..N-1, when N=3, the true median at rank 1 is selected.  For N=9, the elements at rank 3,4 or 5 may be considered as a median, i.e. 1/3 eliminated.  For N=27, the elements between ranks 8 and 20 may be returned as the median, i.e. 7/27 eliminated.  In the limit, as N tends towards infinity (and n tends to infinity), the eliminated fraction (2^n-1)/3^n tends to zero unbounded.  i.e. the larger the input size the less useful is the worst-case median.
The poor quality of the median is lamented by the authors in the penultimate paragraph of section 4.1 of the paper.  They then go on to show that statistically such a worst-case is rare, but unfortunately even a rare worst case breaks the C++ standard libraries O(N) constraint.
(k=3) for the purpose of exact median finding.
methods for finding approximate medians.  The question is how efficient vs.
how approximate.  Many quicksort implementation select the first element as a pivot, an O(1) method for selecting an extremely approximate median!  Statistically over all possible input orders, this first element will on average partition the input array at the median, with some variance.  It's not that the paper is wrong or incorrect; it does what it describes in finding a statistically good approximate median very efficiently with excellent worst case performance.  Unfortunately for the problem we need to solve, which is not the problem the paper's authors were attempting to solve, we need a better approximation perhaps using a more complex implementation.
Can I re-classify this as an enhancement?
I agree with your analysis. I am slightly crestfallen as I was suspicious that Barriato, Hofri etc's paper never mentioned "worst case" only "approximate case".  And I have now seen BFPRT73 paper where it mentions for the number of columns (c) "Note, however, that we must have c >= 5 for PICK to run in linear time". So yes, median-of median of 5 seems best you can do for "worst case".
Roger, are you still actively working on this?
Roger told me in private that he doesn't mean to actively work on this issue any time soon. Unassigning.
Anyway, just because GCC falls back to an O(N log N) algorithm under some circumstances does not necessarily mean it violates the C++ specification, as long as that fallback only happens in log N of the cases or thereabouts.
Not that I am up for actually performing this complexity analysis.

Let's just hope the machines aren't broken.
If you enjoy soft serve and saving money (don't we all?) then we suggest listening up. To celebrate National Ice Cream Day on July 16, not only is McDonald's offering up a sweet deal for everyone, but one lucky person will have the chance to win a LIFETIME supply of free ice cream. We'll just let that sink in for a minute.
Here's what we know: According to Delish, McDonald's has crafted a one-of-a-kind brass-and-real-gold replica of its classic wafer cones. Anyone who downloads the McDonald's app, redeems the free cone coupon, and picks up their ice cream between 2 p.m. and 5 p.m on Sunday (July 16) will be entered to win. You'll have to redeem this one through the drive-through or inside an actual restaurant, even though Mickey D's is bringing delivery to a town near you. One fortunate person will be randomly chosen as the winner, and said person will know right away as the chain will serve up the vanilla swirl in the aforementioned gold cone. But really, everyone is a winner here because you get free ice cream on Sunday no matter what.
Freebies aside, we have some good news for Mickey D's ice cream skeptics: McDonald's began changing its ice cream (and entire menu) in fall of 2016, phasing out artificial ingredients. And apparently the soft serve can be found in 60% of McDonald's desserts, including the new Rolo McFlurry and off-the-menu items such as chocolate chip cookie ice cream sandwiches.
Earlier this year, the company was also forced to purchase thousands of new ice cream machines across multiple locations in the United States and Europe because the stores' machines were always out of order. So, you should be obstacle-free when you go to collect your lifetime supply. Good luck!

Q: C++14 cURLcpp Submitting a form I am trying to use cURLcpp (not cURLpp) to submit a form. In the readme there is an example of how to send a form request. Here is my code:
const std::string authenticityToken = stringMatch.substr(7, stringMatch.length());

curl::curl_form form;
curl::curl_easy easy;
// Forms creation
curl::curl_pair<CURLformoption,std::string> nameForm(CURLFORM_COPYNAME, "username");
curl::curl_pair<CURLformoption,std::string> nameCont(CURLFORM_COPYCONTENTS, "the username");

curl::curl_pair<CURLformoption,std::string> passForm(CURLFORM_COPYNAME, "password");
curl::curl_pair<CURLformoption,std::string> passCont(CURLFORM_COPYCONTENTS, "the password");

curl::curl_pair<CURLformoption,std::string> authForm(CURLFORM_COPYNAME,"authenticityToken");
curl::curl_pair<CURLformoption,std::string> authCont(CURLFORM_COPYCONTENTS, authenticityToken);

try {
    // Form adding
    form.add(nameForm, nameCont);
    form.add(passForm, passCont);
    form.add(authForm, authCont);

    // Add some options to our request
    easy.add<CURLOPT_URL>("https://account.mojang.com/login");
    easy.add<CURLOPT_SSL_VERIFYPEER>(false);
    easy.add<CURLOPT_FOLLOWLOCATION>(1L);
    easy.add<CURLOPT_HTTPPOST>(form);
    // Execute the request.
    easy.perform();
} catch (curl::curl_easy_exception error) {
    // If you want to get the entire error stack we can do:
    curl::curlcpp_traceback errors = error.get_traceback();
    // Otherwise we could print the stack like this:
    error.print_traceback();
    // Note that the printing the stack will erase it
}

I get this error when compiling:
C:\Users\Czarek\ClionProjects\Learning\main.cpp: In function 'int main(int, const char**)':
C:\Users\Czarek\ClionProjects\Learning\main.cpp:40:40: error: no matching function for call to 'curl::curl_easy::add(curl::curl_form&)'
         easy.add<CURLOPT_HTTPPOST>(form);

Now, I followed the example like it was outlined on github? What am I doing wrong?

A: It is clear that curl_easy class does not have any version of add() which accepts curl_form. Looks like only add() variants it has are for CURLOption.

A: I figured it out. Turns out that the tutorial on the website is a little bit wrong. The easy.add<OPT>(value) function accepts a curl_httpost variable. To get it from the curl_form you have to do form.get(). But to pass it to the easy.add() function you have to remove the const with const_cast. I believe this is just a bug in the library.

Early years educators pave the road to reconciliation
Early years educators travelled to USQ Springfield to participate in the forum on Reconciliation and Intercultural Education.
Aboriginal and Torres Strait Islander, Springfield
The important role early learning plays in the reconciliation process was the focus of a professional development workshop at USQ.
More than 40 early years educators from across the region travelled to the University's Springfield campus to participate in the forum on Reconciliation and Intercultural Education.
It included a range of activities and presentations from several Aboriginal and Torres Strait Islander community groups.
The participants explored how our youngest learners can take their first steps in reconciliation through literacy, arts and Indigenous learning experiences.
USQ Lecturer (Early Childhood Curriculum and Pedagogy) and event co-organiser, Dr Eseta Tualaulelei, said that while early years educators are eager to teach reconciliation, they often lack the knowledge or confidence to translate it into practice.
"While there are resources available for teaching Aboriginal and Torres Strait Islander culture, the fear of getting it wrong is holding some educators back," Dr Tualaulelei said.
"Our workshop provided a much-needed opportunity for early years educators to gain practical knowledge and a better understanding of Aboriginal and Torres Strait Islander cultures with the guidance of experienced Indigenous educators.
"Professional learning opportunities like this can help them feel empowered and supported to champion reconciliation through meaningful reconciliation initiatives."
Dr Tualaulelei said early years educators played a critical role in preserving and promoting Aboriginal and Torres Strait Islander language and culture.
"Early years educators have the power to shape young lives every day and incorporating Indigenous traditions into learning experiences can make a significant difference in the reconciliation process," she said.
"Music, dance, painting, storytelling, crafts and bush foods are just some of the activities educators can use to teach children about Aboriginal and Torres Strait Islander history and culture."

From USA Today bestselling author, Willow Winters, comes a seductive and emotionally captivating, second chance romance.
He was everything–irresistibly handsome, ruthlessly elite, and seemingly untouchable–while I was nothing.
If you plan to purchase the books, we'd appreciate it if you used our links. This helps support the blog without costing you anything extra. Thank you for your support.
This is a short novel but is so emotional it has you hanging on by a tissue. There isn't a scene in this one that doesn't wrench a tear from you. I've never read Willow Winters before so I'm not sure if all of her work is this heart wrenching, but this is definitely a change for me. This second chance is all out the romance and love between the two of them, and not really much else.
Maddox's mom is the ultimate bad girl in their romance and really messed things up. Both of them really needed to grow up and live on their own before their love could survive the world around them, but it still hurt when you realized the time they lost. One thing you could tell from the beginning of the story was that she needed him to say, "I love you." He just couldn't realize it himself. Because of that I think it stalled the story and there could have been other obstacles to overcome than just his verbalizing it to her.
I wasn't able to shut if off and sat in the car several times just continuing to listen to it. The story was super gripping and like I said, bring your tissues, you're gonna need 'em. I'm giving this a 4 of 5 because I would have liked a little more of a plot storyline than what I got, but definitely a winner and much needed among all my sweet and suspenseful romance I've been up to lately. Also, the cover is awesome.

Teen stabbed, beat mother with frying pan because she was 'on his case' about cleaning his room
by: Kaycee Sloan
COCOA, Fla. (WFLA) – New details have emerged after a 17-year-old boy was accused of brutally attacking his mother last month.
According to WESH, a report from the Cocoa Police Department said the teen, now charged with attempted murder, stabbed his mother several times before hitting her in the face with a frying pan.

When police arrived, "the victim took a breath and stated [her son] did this," the outlet reported.
During the attack, the suspect's friend tried to get him to stop. Later, the teen left in his mother's Kia and picked up his girlfriend.
WESH stated that the friend who witnessed the attack and another teen followed the suspect and his girlfriend in a Jeep that also belonged to the victim.
After police tracked the suspect by pinging his cell phone, investigators said he refused to stop and led police on a high-speed chase before eventually crashing on Interstate 95.
According to the station, detectives said that while they were interviewing the teen, "he admitted to stabbing the victim multiple times with a pocketknife he carried around…He struck the victim in the head until the frying pan broke."

When asked why he did it, he told officials he was upset that his mother was constantly on him about cleaning his room.
"The suspect advised that he was upset because his mother was constantly on his case about cleaning his room," WESH reported.
