Visual impairment intracranial pressure syndrome (VIIP) is named for the leading theory to explain it. On Earth, gravity pulls bodily fluids down toward the feet. That doesn’t happen in space, and it is thought that extra fluid in the skull increases pressure on the brain and the back of the eye.
This pale, amorphous lump of sculpted concrete is designed to resist almost everything in a city that it might come into contact with. Named for the London authority that commissioned it, the Camden Bench has a special coating which makes it impervious to graffiti and vandalism. The squat, featureless surface gives drug dealers nowhere to hide their secret caches. The angled sides repel skateboarders and flyposters, litter and rain. The cambered top throws off rough sleepers. In fact, it is specially crafted to make sure that it is not used as anything except a bench. This makes it a strange artifact, defined far more by what it is not than what it is. The Camden Bench is a concerted effort to create a non-object.
For the famous Apollo 13 near-fatal failure scenario:
‘A customer has had a fairly serious problem with stirring the cryogenic tanks with a circuit fault present. To reproduce: Build CSM; Perform mission up to translunar coast; During translunar coast, attempt to stir cryo tanks If a wiring fault exists, the issue may be replicated. Be aware that this may be hazardous to the tester attempting it.’ Sample response: ‘Does it happens only with translunar coast (sol-3-a), or any moon coasting? It may be a problem with the moon. Just trying to narrow down the issue.’
Karlin on fire:
But there’s lots in this legislation that should scare the public far more. For example, the proposal that the legislation should allow the retention of “superfluous data” gathered in the course of an investigation, which is a direct contravention of the ECJ’s demand that surveillance must be targeted and data held must be specifically relevant, not a trawl to be stored for later perusal “just in case”. Or the claim that interception and retention of data, and access to it, will only be in cases of the most serious crime or terrorism threats. Oh, please. This was, and remains, the supposed basis for our existing, ECJ-invalidated legislation. Yet, as last year’s Gsoc investigation into Garda leaks revealed, it turns out a number of interconnected pieces of national legislation allow at least 10 different agencies access to retained data, including Gsoc, the Competition Authority, local authorities and the Irish Medicines Board.

npm down for most of the (EU) day. What a shitshow
I haven’t even gotten into the fact that your microservices are an inter-dependent environment, as much as you may wish otherwise, and one service acting up can cause operational problems for the whole team. Maybe if you have Netflix-scale operational hardening that’s not a problem. Do you? Really? Is that the best place to spend your focus and money right now, all so teams can throw shit against the wall to see if it sticks? Don’t sell people fantasies. This is not the reality for a mid-sized tech team working in microservices. There are enough valuable components to building out such a system without the fantastical claims of self-organizing teams who build cool hack projects in 2 week sprints that change the business. Microservices don’t make organizational problems disappear due to self-organization. They allow for some additional degrees of team and process independence and force very explicit decoupling, in exchange, there is overall system complexity and overall system coordination overhead. I personally think that’s enough value, especially when you are coming from a monolith that is failing to scale, but this model is not a panacea.

John Rauser on this oft-cited dictum of percentile usage in monitoring, and when it’s wrong and it’s actually possible to reason with averaged percentiles, and when it breaks down.
In their paper at PNAS, they write: “the most common software packages for fMRI analysis (SPM, FSL, AFNI) can result in false-positive rates of up to 70%. These results question the validity of some 40,000 fMRI studies and may have a large impact on the interpretation of neuroimaging results.” For example, a bug that’s been sitting in a package called 3dClustSim for 15 years, fixed in May 2015, produced bad results (3dClustSim is part of the AFNI suite; the others are SPM and FSL). That’s not a gentle nudge that some results might be overstated: it’s more like making a bonfire of thousands of scientific papers. Further: “Our results suggest that the principal cause of the invalid cluster inferences is spatial autocorrelation functions that do not follow the assumed Gaussian shape”. The researchers used published fMRI results, and along the way they swipe the fMRI community for their “lamentable archiving and data-sharing practices” that prevent most of the discipline’s body of work being re-analysed. ®

Good thread on GCM notifications and their interactions with NAT — they are delivered over a single TCP connection to port 5228 to the google servers, kept alive, and NAT timeouts can hang the conn resulting in delayed notifications. Particularly useful is the *#*#426#*#* dial code, which displays a log screen on Android devices with GCM debugging info.

“Dad is making a right turn now,” my 5-year-old son Jack will say as he newscasts the ride to school to a fictional audience. “Don’t forget to subscribe,” his sister Ella, 6, will often interject — again, to no one in particular. When I was their age, I’d pretend to be a soldier or a baseball player. Today, kids apparently aspire to be vloggers. It’s not enough for them to watch their favorite shows. They want to broadcast their lives, banter with commenters and keep their make-believe view counts high.
Law enforcement spokespeople will often point to the handful of homicide or kidnapping investigations successfully closed with the assistance of cell site simulators, but they’ll gloss over the hundreds of mundane deployments performed by officers who will use anything that makes their job easier — even if it’s a tool that’s Constitutionally dubious. Don’t forget, when a cell site simulator is deployed, it gathers cell phone info from everyone in the surrounding area, including those whose chicken wings have been lawfully purchased. And all of this data goes… somewhere and is held onto for as long as the agency feels like it, because most agencies don’t seem to have Stingray data retention policies in place until after they’ve been FOIA’ed/questioned by curious legislators. Regular policework — which seemed to function just fine without cell tracking devices — now apparently can’t be done without thousands of dollars of military equipment. And it’s not just about the chicken wing thieves law enforcement can’t locate. It’s about the murder suspects who are caught but who walk away when the surveillance device wipes its feet on the Fourth Amendment as it serves up questionable, post-facto search warrants and pen register orders.

Post-brexit post-mortem from Nicholas Cohen in the grauniad:
The Vote Leave campaign followed the tactics of the sleazy columnist to the letter. First, it came out with the big, bold solution: leave. Then it dismissed all who raised well-founded worries with “the country is sick of experts”. Then, like Johnson the journalist, it lied.
The prime minister evidently thought that the whole debate could be cleanly started and finished in a matter of months. His Eton contemporary Boris Johnson – and, really, can you believe that the political story of the last four months has effectively been a catastrophic contest between two people who went to the same exclusive school? – opportunistically embraced the cause of Brexit in much the same spirit. What they had not figured out was that a diffuse, scattershot popular anger had not yet decisively found a powerful enough outlet, but that the staging of a referendum and the cohering of the leave cause would deliver exactly that. Ukip were held back by both the first-past-the-post electoral system, and the polarising qualities of Farage, but the coalition for Brexit effectively neutralised both. And so it came to pass: the cause of leaving the EU, for so long the preserve of cranks and chancers, attracted a share of the popular vote for which any modern political party would give its eye teeth.
More trial-by-algorithm horrors:
Company officials say the algorithm’s results are backed by research, but they are tight-lipped about its details. They do acknowledge that men and women receive different assessments, as do juveniles, but the factors considered and the weight given to each are kept secret. “The key to our product is the algorithms, and they’re proprietary,” said Jeffrey Harmon, Northpointe’s general manager. “We’ve created them, and we don’t release them because it’s certainly a core piece of our business. It’s not about looking at the algorithms. It’s about looking at the outcomes.” That secrecy is at the heart of Mr. Loomis’s lawsuit. His lawyer, Michael D. Rosenberg, who declined to be interviewed because of the pending appeal, argued that Mr. Loomis should be able to review the algorithm and make arguments about its validity as part of his defense. He also challenges the use of different scales for each sex. The Compas system, Mr. Rosenberg wrote in his brief, “is full of holes and violates the requirement that a sentence be individualized.”
Appearing like trenches dragged into the earth, sunken lanes, also called hollow-ways or holloways, are centuries-old thoroughfares worn down by the traffic of time.

So, there you have it: Blocking is necessary, except it is not. Safeguards need to be implemented, except they don’t need to be. This approach is legal, except it isn’t. The text is based on the Child Exploitation Directive, except it isn’t. Is this really how we are going to create credible legislation on terrorism?
After studying other e-voting systems around the world, the team was particularly alarmed by the Estonian I-voting system. It has serious design weaknesses that are exacerbated by weak operational management. It has been built on assumptions which are outdated and do not reflect the contemporary reality of state-level attacks and sophisticated cybercrime. These problems stem from fundamental architectural problems that cannot be resolved with quick fixes or interim steps. While we believe e-government has many promising uses, the Estonian I-voting system carries grave risks — elections could be stolen, disrupted, or cast into disrepute. In light of these problems, our urgent recommendation is that to maintain the integrity of the Estonian electoral process, use of the Estonian I-voting system should be immediately discontinued.
Reducing service memory usage from 500MB to 105MB:

A collection of bits and pieces of Internet history. Focusing somewhat (but not exclusively) on: (a) the 1980s, when I first started using the Internet, and: (b) Ireland.
I need to get in touch about the early days of the Irish web!
an online home for stories from Ireland – stories about the country’s long and convoluted relationship with information technology. It aims to gather information on the most significant aspects of this relationship, to compile archives on the selected themes, and to store the assembled records for the benefit of future generations.
This site is a companion effort to the techarchives website, except it is less well-researched, and is primarily a personal view of the development of the Internet in Ireland by your humble author, Niall Murphy.
An old post about Y!’s acquisition of Summly, an iPhone app which uses NLP to summarise news stories. This is an excellent point about modern tech startups:
[Summly] licensed the core engine from another company. They are the quintessential bolt-on engineers, taking a Japanese bike engine, slapping together a badly constructed frame aligned solely by eyeballs, and laying down a marketing blitz. That’s why the story sells. “You, too, can do it.” But do you want to? […] it’s critical to keep tabs on the ratio known as “glue versus thought.” Sure, both imply progress and both are necessary. But the former is eminently mundane, replaceable, and outsource-able. The latter is typically what gives a company its edge, what is generally regarded as a competitive advantage. So, what is Yahoo signaling to the world? “We value glue more than thought.”
on the history of Irish cuisine — mostly milk and butter, and notably “bog butter”:
And the Irish didn’t like their butter just one way: from the 12th century on, there are records of butter flavored with onion and garlic, and local traditions of burying butter in bogs. Originally, it’s thought that bog butter began as a good storage system, but after a time, buried bog butter came to be valued for its uniquely boggy flavor.
Paypal will no longer handle payments if the user’s address includes the word “Isis”:
That these place names exist won’t be a surprise to anyone familiar with English limnology – the study of rivers and inland waters. As Wikipedia helpfully tells us, “The Isis is the name given to the part of the River Thames above Iffley Lock which flows through the university city of Oxford”. In at least one local primary school I’m familiar with, the classes are called Windrush, Cherwell, Isis and Thames. […] Now PayPal has decided that they are not prepared to facilitate payments for goods to be delivered to an address which includes the word “Isis”. An Isis street resident ran into some unexpected difficulties when attempting to purchase a small quantity of haberdashery on the internet with the aid of a PayPal account. The transaction would not process. In puzzlement she eventually got irritated enough to brave the 24/7 customer support telephone tag labyrinth. The short version of the response from the eventual real person she managed to get through to was that PayPal have blacklisted addresses which include the name “Isis”. They will not process payments for goods to be delivered to an Isis related address, whatever state of privileged respectability the residents of such properties may have earned or inherited in their lifetimes to this point.One has to wonder if this also brings the risk of adding the user to a secret list, somewhere. Trial by algorithm.
Oh thank god, there’s a “get out of jail” card before they destroy the global economy to appease the eurosceptics.
On the day after a vote for Brexit, the UK will still be a member state of the EU. All the legislation which gives effect to EU law will still be in place. Nothing as a matter of law changes in any way just because of a vote to Leave. What will make all the legal difference is not a decision to leave by UK voters in a non-binding advisory vote, but the decision of the prime minister on how to react before making any Article 50 notification. And what the prime minister will do politically after a referendum vote for Brexit is, at the moment, as unknown as the result of the result of the referendum itself.

Three, the mobile carrier, has begun warming up for a network-level ad blocking trial. It will become one of the first mobile carriers worldwide—and certainly in the UK—to try blocking ads before they are squirted over the network to the consumer, rather than attempting to hide or block ads locally on the device, which can cost both bandwidth and battery life. The ad blocking trial, which will affect both mobile websites and apps, will take place during a 24-hour period sometime between June 13 and 20. Three says it will contact customers and ask them to sign up for the trial, presumably via the online customer portal. It isn’t clear how large the trial will be. Technologically, the network-level ad blocking will be powered by Shine. Due to the nature of the beast—the constant tussle between ad publishers and ad blockers—Shine doesn’t like to talk about its tech in much detail. It sounds like Shine uses deep packet inspection and machine learning to find packets that contain ads, and then replaces or removes them in such a way that it doesn’t break the layout of the website or app.
R.I.Pienaar talks about the conventions he uses when containerising; looks like a decent approach.
‘ClickHouse manages extremely large volumes of data in a stable and sustainable manner. It currently powers Yandex.Metrica, world’s second largest web analytics platform, with over 13 trillion database records and over 20 billion events a day, generating customized reports on-the-fly, directly from non-aggregated data. This system was successfully implemented at CERN’s LHCb experiment to store and process metadata on 10bn events with over 1000 attributes per event registered in 2011.’ Yandex-tastic, but still looks really interesting
Creating a read replica in another region also creates an Aurora cluster in the region. This cluster can contain up to 15 more read replicas, with very low replication lag (typically less than 20 ms) within the region (between regions, latency will vary based on the distance between the source and target). You can use this model to duplicate your cluster and read replica setup across regions for disaster recovery. In the event of a regional disruption, you can promote the cross-region replica to be the master. This will allow you to minimize downtime for your cross-region application. This feature applies to unencrypted Aurora clusters.

The Garda Síochána has proposed to expand its surveillance on Irish citizens by swelling the amount of data it collects on them through an increase in its CCTV and ANPR set-ups, and will also introduce facial and body-in-a-crowd biometrics technologies. […] The use of Automated Facial Recognition (AFR) technology is fairly troubled in the UK, with the independent biometrics commissioner warning the government that it was risking inviting a legal challenge back in March. It is no less of an issue in Ireland, where the Data Protection Commissioner (DPC) audited Facebook in 2011 and 2012, and scolded the Zuckerborg over its use of facial recognition technology.
“Here,” by Richard McGuire. Amazing piece of comic art from 1989
What happened today? We still don’t really know, but it seems we found a first potentially malicious collision — that is, the first “nonacademic” case. Enrico found two keys sharing the 9F6C6333 short ID, apparently belonging to the same person (as would be the case of Asheesh, mentioned above). After contacting Gustavo, though, he does not know about the second — That is, it can be clearly regarded as an impersonation attempt. Besides, what gave away this attempt are the signatures it has: Both keys are signed by what appears to be the same three keys: B29B232A, F2C850CA and 789038F2. Those three keys are not (yet?) uploaded to the keyservers, though… But we can expect them to appear at any point in the future. We don’t know who is behind this, or what his purpose is. We just know this looks very evil. Now, don’t panic: Gustavo’s key is safe. Same for his certifiers, Marga, Agustín and Maxy. It’s just a 32-bit collision. So, in principle, the only parties that could be cheated to trust the attacker are humans, right? Nope. Enrico tested on the PGP pathfinder & key statistics service, a keyserver that finds trust paths between any two arbitrary keys in the strong set. Surprise: The pathfinder works on the short key IDs, even when supplied full fingerprints. So, it turns out I have three faked trust paths into our impostor.
The IWF in the spotlight…
The blacklist operated by the IWF effectively amounts to censorship. Not only are the blacklist and notices sent to members of the IWF kept secret, but there is no requirement to notify website owners when their site has been added to the blacklist. Even where statutory rules do exist with respect to notice and take-down procedures (namely, the Terrorism Act 2006 and the Defamation (Operators of Websites) Regulations 2013), the provisions are not so concerned with safeguards for the protection of freedom of expression, as with offering an exemption from liability for ISPs.

Adobe was fined 8,000 euros, Punica 9,000 euros and Unilever 11,000 euros. The regulator said they had put in place alternative legal mechanisms for transferring data to the United States following the fine. “The fact that the companies have eventually implemented a legal basis for the transfer had to be taken into account in a favorable way for the calculation of the fines,” said Johannes Caspar, the Hamburg Commissioner for Data Protection. “For future infringements, stricter measures have to be applied.”

‘There is a popular belief in neuroscience that we are primarily data limited, that producing large, multimodal, and complex datasets will, enabled by data analysis algorithms, lead to fundamental insights into the way the brain processes information. Microprocessors are among those artificial information processing systems that are both complex and that we understand at all levels, from the overall logical flow, via logical gates, to the dynamics of transistors. Here we take a simulated classical microprocessor as a model organism, and use our ability to perform arbitrary experiments on it to see if popular data analysis methods from neuroscience can elucidate the way it processes information. We show that the approaches reveal interesting structure in the data but do not meaningfully describe the hierarchy of information processing in the processor. This suggests that current approaches in neuroscience may fall short of producing meaningful models of the brain.’ via Bryan O’Sullivan.

‘centrally-planned object and thread pools’ for java. ‘In the default JVM thread pools, once a thread is created it will only be retired when it hasn’t performed a task in the last minute. In practice, this means that there are as many threads as the peak historical number of concurrent tasks handled by the pool, forever. These thread pools are also poorly instrumented, making it difficult to tune their latency or throughput. Dirigiste provides a fast, richly instrumented version of a java.util.concurrent.ExecutorService, and provides a means to feed that instrumentation into a control mechanism that can grow or shrink the pool as needed. Default implementations that optimize the pool size for thread utilization are provided. It also provides an object pool mechanism that uses a similar feedback mechanism to resize itself, and is significantly simpler than the Apache Commons object pool implementation.’ Great metric support, too.

Anecdotal evidence has suggested simulator sickness is less intense when games contain fixed visual reference objects – such as a racecar’s dashboard or an airplane’s cockpit – located within the user’s field of view. “But you can’t have a cockpit in every VR simulation,” Whittinghill said. His research team was studying the problem when undergraduate student Bradley Ziegler suggested inserting the image of a virtual human nose in the center of the video display. “It was a stroke of genius,” said Whittinghill, who teaches video game design. “You are constantly seeing your own nose. You tune it out, but it’s still there, perhaps giving you a frame of reference to help ground you.” The researchers have discovered that the virtual nose, or “nasum virtualis,” reduces simulator sickness when inserted into popular games.

backward compatible replacement for Dockerfile. Yes, you can take any Dockerfile, rename it to Rockerfile and use rocker build instead of docker build. … Rocker aims to solve the following use cases, which are painful with plain Docker: Mount reusable volumes on build stage, so dependency management tools may use cache between builds. Share ssh keys with build (for pulling private repos, etc.), while not leaving them in the resulting image. Build and run application in different images, be able to easily pass an artifact from one image to another, ideally have this logic in a single Dockerfile. Tag/Push images right from Dockerfiles. Pass variables from shell build command so they can be substituted to a Dockerfile. And more. These are the most critical issues that were blocking our adoption of Docker at Grammarly. The most challenging part is caching. While implementing those features seems to be not a big deal, it’s not trivial to do that just by utilising Docker’s image cache (the one that docker build does). Actually, it is the main reason why those features are still not in Docker. With Rocker we achieve this by introducing a set of trade-offs. Search this page for “trade-off” to find out more details.
Sadly (because I want a “holodeck” as much as the next red-blooded geek) – I don’t think it’s possible to make a VR system that both delivers the experience that everyone wants – and doesn’t make a sizeable proportion of the population so sick that they’ll never want to do it again. For the people who can stomach the display – my major concern is that the US Navy studies show that there is some disorientation that might persist long after finishing your game…so driving a car while “under the influence” of post-VR disorientation is probably as dangerous as drunk-driving. If these devices are in pretty much every home – then there are huge problems in store for the industry in terms of product liability. There have been plenty of warnings from the flight simulation industry – there are no excuses for not reading the Wikipedia article on the subject. If people are driving “under the influence” and the VR companies didn’t warn them about that – then they’re in deep trouble. IMHO, these consumer-grade VR devices should be carefully studied and if they do cause possible driving impairment, they should be banned until such time as the problems can be fixed…which may very well be “never”. Sorry to be the bearer of bad news.(via Tony Finch)

n the morning of May 12, LinkedIn, the networking site devoted to making professionals “more productive and successful,” emailed scores of my contacts and told them I’m a professional racist. It was one of those updates that LinkedIn regularly sends its users, algorithmically assembled missives about their connections’ appearances in the media. This one had the innocent-sounding subject, “News About William Johnson,” but once my connections clicked in, they saw a small photo of my grinning face, right above the headline “Trump put white nationalist on list of delegates.” […..] It turns out that when LinkedIn sends these update emails, people actually read them. So I was getting upset. Not only am I not a Nazi, I’m a Jewish socialist with family members who were imprisoned in concentration camps during World War II. Why was LinkedIn trolling me?

Systemd breaks UNIX behaviour which has been standard practice for 30 years:
It is now indeed the case that any background processes that were still running are killed automatically when the user logs out of a session, whether it was a desktop session, a VT session, or when you SSHed into a machine. Now you can no longer expect a long running background processes to continue after logging out. I believe this breaks the expectations of many users. For example, you can no longer start a screen or tmux session, log out, and expect to come back to it.
Geofencing used for evil:
What Flynn realized is that he could use [ad targeting] to infer that a woman might be seeking an abortion, and to target her for ads from anti-choice groups [using geofenced advertising]. “We can reach every Planned Parenthood in the U.S.,” he wrote in a PowerPoint display sent to potential clients in February. The Powerpoint included a slide titled “Targets for Pro-Life,” in which Flynn said he could also reach abortion clinics, hospitals, doctors’ offices, colleges, and high schools in the United States and Canada, and then “[d]rill down to age and sex.” “We can gather a tremendous amount of information from the [smartphone] ID,” he wrote. “Some of the break outs include: Gender, age, race, pet owners, Honda owners, online purchases and much more.” Flynn explained that he would then use that data to send anti-choice ads to women “while they’re at the clinic.”
Rapid Fire is a special event we started hosting at our own in-person CTFs in 2014. The idea is pretty simple: Create several CTF challenges that can be solved in a few minutes each. Set up the challenges on 4 identical computers with some basic tools. Mirror the player’s screens so the audience can watch their actions. Whoever solves the most challenges the fastest wins. This event is interesting for a number of reasons: the players are under intense pressure, as everything they do is being watched by several people; the audience can watch several different approaches to the same problems; and people can follow along fairly easily with what is going on with the challenges.With e-sports-style video!
Twitter are open sourcing their Storm replacement, and moving it to an independent open source foundation
If it’s illegal to write clean room implementations of APIs, then no one has clean hands. The now-shelved open source project Apache Harmony, like Android, reimplemented Java SE, and tech giant IBM contributed code to that project. Oracle itself built its business off a proprietary implementation of SQL, which was created by IBM. The proposition “Reimplementations of APIs are infringements” creates a recursive rabbit hole of liability that spans across the industry. Even the very 37 Java APIs at issue in this trial contain reimplementations of other APIs. Google witness Joshua Bloch—who, while at Sun Microsystems, wrote many of the Java APIs—testified that specific Java APIs are reimplementations of other APIs from Perl 5 and the C programming language.

‘The algorithm of Lamport timestamps is a simple algorithm used to determine the order of events in a distributed computer system. As different nodes or processes will typically not be perfectly synchronized, this algorithm is used to provide a partial ordering of events with minimal overhead, and conceptually provide a starting point for the more advanced vector clock method. They are named after their creator, Leslie Lamport.’ See also vector clocks (which I think would be generally preferable nowadays).

Automated DMCA takedowns used to fraudulently censor online content.
In fact, no copyright infringement had occurred at all. Instead, something weirder had happened. At some point after Narey posted her comments on Mumsnet, someone had copied the entire text of one of her posts and pasted it, verbatim, to a spammy blog titled “Home Improvement Tips and Tricks”. The post, headlined “Buildteam interior designers” was backdated to September 14 2015, three months before Narey had written it, and was signed by a “Douglas Bush” of South Bend, Indiana. The website was registered to someone quite different, though: Muhammed Ashraf, from Faisalabad, Pakistan. Quite why Douglas Bush or Muhammed Ashraf would be reviewing a builder based in Clapham is not explained in “his” post. BuildTeam says it has no idea why Narey’s review was reposted, but that it had nothing to do with it. “At no material times have we any knowledge of why this false DCMA take down was filed, nor have we contracted any reputation management firms, or any individual or a group to take such action on our behalf. Finally, and in conjunction to the above, we have never spoken with a ‘Douglas Bush,’ or a ‘Muhammed Ashraf.’”
This totally matches my own preconceptions ;)
When we at Datawire tried to actually use Lambda for a real-world HTTP-based microservice […], we found some uncool things that make Lambda not yet ready for the world we live in: Lambda is a building block, not a tool; Lambda is not well documented; Lambda is terrible at error handling Lung skips these uncool things, which makes sense because they’d make the tutorial collapse under its own weight, but you can’t skip them if you want to work in the real world. (Note that if you’re using Lambda for event handling within the AWS world, your life will be easier. But the really interesting case in the microservice world is Lambda and HTTP.)
holy crap, this is dystopian:
The first time Paul Zilly heard of his score — and realized how much was riding on it — was during his sentencing hearing on Feb. 15, 2013, in court in Barron County, Wisconsin. Zilly had been convicted of stealing a push lawnmower and some tools. The prosecutor recommended a year in county jail and follow-up supervision that could help Zilly with “staying on the right path.” His lawyer agreed to a plea deal. But Judge James Babler had seen Zilly’s scores. Northpointe’s software had rated Zilly as a high risk for future violent crime and a medium risk for general recidivism. “When I look at the risk assessment,” Babler said in court, “it is about as bad as it could be.” Then Babler overturned the plea deal that had been agreed on by the prosecution and defense and imposed two years in state prison and three years of supervision.

Today in nose-leech news — the paper!
Principal Findings: A new genus and species of leech from Perú was found feeding from the nasopharynx of humans. Unlike any other leech previously described, this new taxon has but a single jaw with very large teeth. Phylogenetic analyses of nuclear and mitochondrial genes using parsimony and Bayesian inference demonstrate that the new species belongs among a larger, global clade of leeches, all of which feed from the mucosal surfaces of mammals. Conclusions: This new species, found feeding from the upper respiratory tract of humans in Perú, clarifies an expansion of the family Praobdellidae to include the new species Tyrannobdella rex n. gen. n.sp., along with others in the genera Dinobdella, Myxobdella, Praobdella and Pintobdella. Moreover, the results clarify a single evolutionary origin of a group of leeches that specializes on mucous membranes, thus, posing a distinct threat to human health.
This is an eye-opener:
A former bicycle thief has revealed the tricks of the trade in an interview, which clearly and shockingly shows the extent that thieves will go to in order to steal a bike. He talks about the motivations behind the theft, the tools used to crack locks and how the bikes were moved around and sold for a significant sum. He also gives tips on how to prevent your bike from being stolen. […] ‘Don’t be fooled by Kryptonite locks, they’re not as tough as made out to be. Also D-bars with tubular locks, never use them, they’re the most easy to pick with a little tool. It’s small and discreet, no noise and it looks like you are just unlocking your bike. With the bolt cutters we would go out on high performance motorbikes, two men on a bike.’
Of the dozens of Trump pages seemingly run by click-farms, just one responded to our request for an interview, though the anonymous operators of the Trumpians fan page declined to provide the name of their company, citing the “volatility of Trump haters.” Trump’s Facebook page is the only one of over 100 the company runs that’s dedicated to an individual politician. “The other [candidates] don’t have any value from a merchandise perspective ,” the operator said by Facebook Messenger.

Excellent advice on capacity planning and queueing theory, in the context of Hystrix. Should I use a single thread pool for all dependency callouts, or independent thread pools for each one?

The Language Creation Society filed an amicus brief claiming that Klingon is a real language and therefore not subject to copyright. To reiterate: the fandom of Star Trek elevated a language invented in 1984 by Marc Okrand for Star Trek III: The Search for Spock to the point it is taught in colleges and spoken as a living language. So it isn’t Star Trek anymore: it is real. […] the entire legal brief is impossible to reprint due to limits in our non-Klingon font system, but even the motion includes Klingon-translated passages that accuse Paramount of being “arrogant” and “pathetic”.
This is quite significant — scientific proof that austerity/social engineering policies cause higher mortality rates:
Researchers found that the historic effect of overcrowding was an important factor and highlighted the strategies of local government, which prioritised the regeneration of the city centre over investment in the cities housing schemes as having a significant impact on the health of Glaswegians. Data shows that Glasgow authorities spent far less on housing repairs, leaving people’s homes poorly maintained and subject to damp. David Walsh, of the Glasgow Centre for Population Health, said that their work proved that poor health had political causes and could not simply be attributed to individual lifestyle choices.
Very DataDog-oriented, but some decent tips on monitorable metrics here

Kodak’s purpose for the reactor wasn’t sinister: they used it to check materials for impurities as well as neutron radiography testing. The reactor, a Californium Neutron Flux multiplier (CFX) was acquired in 1974 and loaded with three and a half pounds of enriched uranium plates placed around a californium-252 core. The reactor was installed in a closely guarded, two-foot-thick concrete walled underground bunker in the company’s headquarters, where it was fed tests using a pneumatic system. According to the company, no employees were ever in contact with the reactor. Apparently, it was operated by atomic fairies and unicorns.

What the hell, Virgin?
Section 12: Use of Virtual Private Network (VPN) As stated above, the Virgin Media Services are for residential use only and we do not support the use of VPN. If we find you are using VPN we may instruct you to stop using it and you must comply with this request. This is in order to prevent problems with our network and other Internet users.
Virgin Media/UPC seem to have silently deployed an IPv6 “carrier-grade NAT” setup called “DS-Lite” — ie. all customers now get just a routable IPv6 address, and share a small pool of IPv4 NATs. This breaks a multitude of useful services, including UDP IPSec VPNs it seems
omg. Sean “Irish SOPA” Sherlock dealing with the important issues once again — in this case the bloody “Unified Patent Court”
In his 1962 book, The Image: A Guide to Pseudo-Events in America, former Librarian of Congress Daniel J. Boorstin describes a world where our ability to technologically shape reality is so sophisticated, it overcomes reality itself. “We risk being the first people in history,” he writes, “to have been able to make their illusions so vivid, so persuasive, so ‘realistic’ that they can live in them.”

China’s Internet censors are capricious and impossible to predict — but this isn’t because China’s censors are incompetent, rather, they’re tapping into one of the most powerful forms of conditioning, the uncertainty born of intermittent reinforcement. […] As C Custer writes at Tech in Asia, this caprice is by design: by not specifying a set of hard and fast rules, but rather the constant risk of being taken down for crossing some invisible line, China’s censors inspire risk-aversion in people who rely on the net to be heard or earn their livings. It’s what Singaporeans call “out of bounds,” the unspecified realm of things you mustn’t, shouldn’t or won’t want to enter.
These are a great selection. Gonna be doing one of these every weekend if possible, now that the 2 year old can just about handle it ;)
command line utility that performs an HTML element selection on HTML content passed to the stdin. Using css selectors that everybody knows. Since input comes from stdin and output is sent to stdout, it can easily be used inside traditional UNIX pipelines to extract content from webpages and html files. tq provides extra formating options such as json-encoding or newlines squashing, so it can play nicely with everyones favourite command line tooling.
some amazingly terrible product decisions here. Deleting local copies of unreleased WAV files — on the assumption that the user will simply listen to them streamed down from Apple Music — that is astonishingly bad, and it’s amazing they didn’t consider the “freelance composer” use case at all.

Purpose-built in 1898, the telephone exchange in Temple Bar was Dublin’s first automatic telephone exchange. Much like its newer neighbor, Internet House, it stood as a technological beacon shining through the luddite fog. With this in mind the Irish Citizen Army targeted the Telephone Exchange in 1916 as one of the communication hubs for the island. While many of us grew up learning of a history of ‘blood sacrifice’ and the futility of the Easter Rising, the truth is that the attack was meticulously planned both militarily and logistically. Sixty communication points around Dublin were hit in an effort to cut off all contact between British military forces within Ireland and to the ‘mainland’. The hope being that reserves and reinforcements would be delayed or misinformed.[…] Unfortunately for the rebels they could not take the Temple Bar exchange. A failure that would prove disastrous.
