  • Twitter’s new anti-harassment filter

    Twitter is calling it a “quality filter,” and it’s been rolling out to verified users running Twitter’s iOS app since last week. It appears to work much like a spam filter, except instead of hiding bots and copy-paste marketers, it screens “threats, offensive language, [and] duplicate content” out of your notifications feed.

  • 5% of Google visitors have ad-injecting malware installed

    Ad injectors were detected on all operating systems (Mac and Windows), and web browsers (Chrome, Firefox, IE) that were included in our test. More than 5% of people visiting Google sites have at least one ad injector installed. Within that group, half have at least two injectors installed and nearly one-third have at least four installed.

  • On Ruby

    The horrors of monkey-patching:

    I call out the Honeybadger gem specifically because was the most recent time I’d been bit by a seemingly good thing promoted in the community: monkey patching third party code. Now I don’t fault Honeybadger for making their product this way. It provides their customers with direct business value: “just require ‘honeybadger’ and you’re done!” I don’t agree with this sort of practice. [....] I distrust everything [in Ruby] but a small set of libraries I’ve personally vetted or are authored by people I respect. Why is this important? Without a certain level of scrutiny you will introduce odd and hard to reproduce bugs. This is especially important because Ruby offers you absolutely zero guarantee whatever the state your program is when a given method is dispatched. Constants are not constants. Methods can be redefined at run time. Someone could have written a time sensitive monkey patch to randomly undefined methods from anything in ObjectSpace because they can. This example is so horribly bad that no one should every do, but the programming language allows this. Much worse, this code be arbitrarily inject by some transitive dependency (do you even know what yours are?).

  • Stairs to nowhere, trap streets, and other Toronto oddities

    ‘There’s a set of stairs on Greenwood Avenue that lead nowhere. At the top, a wooden fence at the end of someone’s back yard blocks any further movement, forcing the climber to turn around and descend back to the street. What’s remarkable about the pointless Greenwood stairs, which were built in 1959 as a shortcut to a now-demolished brickyard, is that someone still routinely maintains them: in winter, some kindly soul deposits a scattering of salt lest one of the stairs’ phantom users slip; in summer someone comes with a broom to sweep away leaves. These urban leftovers are lovingly called “Thomassons” after Gary Thomasson, a former slugger for the San Francisco Giants, Oakland As, Yankees, Dodgers, and, most fatefully, the Yomiuri Giants in Tokyo.’

  • President’s message gets lost in (automated) translation

    In a series of bizarre translations, YouTube’s automated translation service took artistic licence with the [President's] words of warmth. When the head of state sent St Patrick’s Day greetings to viewers, the video sharing site said US comedian Tina Fey was being “particular with me head”. As President Higgins spoke of his admiration for Irish emigrants starting new communities abroad, YouTube said the President referenced blackjack and how he “just couldn’t put the new iPhone” down. And, in perhaps the most unusual moment, as he talked of people whose hearts have sympathy, the President “explained” he was once on a show “that will bar a gift card”.

  • Irish government under fire for turning its back on basic research : Nature News & Comment

    Pretty much ALL of Ireland’s research scientists have put their names to an open letter to the Irish government, decrying the state of science funding, published this week in “Nature”. ‘Although total spending on research and development grew through the recession, helped by foreign investments, Ireland’s government has cut state spending on research (see ‘Celtic tiger tamed’). It also prioritized grants in 14 narrow areas — ones in which either large global markets exist, or in which Irish companies are competitive. These include marine renewable energy, smart grids, medical devices and computing. The effect has been to asphyxiate the many areas of fundamental science — including astrophysics, particle physics and areas of the life sciences — that have been deprived of funding, several researchers in Ireland told Nature. “The current policies are having a very significant detrimental effect on the health and viability of the Irish scientific ecosystem,” says Kevin Mitchell, a geneticist who studies the basis of neurological disorders at Trinity College Dublin. “Research that cannot be shoehorned into one of the 14 prioritized areas has been ineligible for most funding,” he says.’ That’s another fine mess Sean Sherlock has gotten us into :(

  • Mars One finalist Dr. Joseph Roche rips into the project

    So, here are the facts as we understand them: Mars One has almost no money. Mars One has no contracts with private aerospace suppliers who are building technology for future deep-space missions. Mars One has no TV production partner. Mars One has no publicly known investment partnerships with major brands. Mars One has no plans for a training facility where its candidates would prepare themselves. Mars One’s candidates have been vetted by a single person, in a 10-minute Skype interview. “My nightmare about it is that people continue to support it and give it money and attention, and it then gets to the point where it inevitably falls on its face,” said Roche. If, as a result, “people lose faith in NASA and possibly even in scientists, then that’s the polar opposite of what I’m about. If I was somehow linked to something that could do damage to the public perception of science, that is my nightmare scenario.”

  • Epsilon Interactive breach the Fukushima of the Email Industry (CAUCE)

    Upon gaining access to an ESP, the criminals then steal subscriber data (PII such as names, addresses, telephone numbers and email addresses, and in one case, Vehicle Identification Numbers). They then use ESPs’ mailing facility to send spam; to monetize their illicit acquisition, the criminals have spammed ads for fake Adobe Acrobat and Skype software. On March 30, the Epsilon Interactive division of Alliance Data Marketing (ADS on NASDAQ) suffered a massive breach that upped the ante, substantially.  Email lists of at least eight financial institutions were stolen.  Thus far, puzzlingly, Epsilon has refused to release the names  of compromised clients. [...] The obvious issue at hand is the ability of the thieves to now undertake targeted spear-phishing problem as critically serious as it could possibly be.

  • In Ukraine, Tomorrow’s Drone War Is Alive Today

    Drones, hackerspaces and crowdfunding:

    The most sophisticated UAV that has come out of the Ukrainian side since the start of the conflict is called the PD-1 from developer Igor Korolenko. It has a wingspan of nearly 10 feet, a five-hour flight time, carries electro-optical and infrared sensors as well as a video camera that broadcasts on a 128 bit encrypted channel. Its most important feature is the autopilot software that allows the drone to return home in the event that the global positioning system link is jammed or lost. Drone-based intelligence gathering is often depicted as risk-free compared to manned aircraft or human intelligence gathering, but, says Korolenko, if the drone isn’t secure or the signature is too obvious, the human coasts can be very, very high. “Russian military sometimes track locations of ground control stations,” he wrote Defense One in an email. “Therefore UAV squads have to follow certain security measures – to relocate frequently, to move out antennas and work from shelter, etc. As far as I know, two members of UAV squads were killed from mortar attacks after [their] positions were tracked by Russian electronic warfare equipment.”

  • Japan’s Robot Dogs Get Funerals as Sony Looks Away

    in July 2014, [Sony's] repairs [of Aibo robot dogs] stopped and owners were left to look elsewhere for help. The Sony stiff has led not only to the formation of support groups–where Aibo enthusiasts can share tips and help each other with repairs–but has fed the bionic pet vet industry. “The people who have them feel their presence and personality,” Nobuyuki Narimatsu, director of A-Fun, a repair company for robot dogs, told AFP. “So we think that somehow, they really have souls.” While concerted repair efforts have kept many an Aibo alive, a shortage of spare parts means that some of their lives have come to an end.

  • “Cuckoo Filter: Practically Better Than Bloom”

    ‘We propose a new data structure called the cuckoo filter that can replace Bloom filters for approximate set membership tests. Cuckoo filters support adding and removing items dynamically while achieving even higher performance than Bloom filters. For applications that store many items and target moderately low false positive rates, cuckoo filters have lower space overhead than space-optimized Bloom filters. Our experimental results also show that cuckoo filters outperform previous data structures that extend Bloom filters to support deletions substantially in both time and space.’

  • Ask the Decoder: Did I sign up for a global sleep study?

    How meaningful is this corporate data science, anyway? Given the tech-savvy people in the Bay Area, Jawbone likely had a very dense sample of Jawbone wearers to draw from for its Napa earthquake analysis. That allowed it to look at proximity to the epicenter of the earthquake from location information. Jawbone boasts its sample population of roughly “1 million Up wearers who track their sleep using Up by Jawbone.” But when looking into patterns county by county in the U.S., Jawbone states, it takes certain statistical liberties to show granularity while accounting for places where there may not be many Jawbone users. So while Jawbone data can show us interesting things about sleep patterns across a very large population, we have to remember how selective that population is. Jawbone wearers are people who can afford a $129 wearable fitness gadget and the smartphone or computer to interact with the output from the device. Jawbone is sharing what it learns with the public, but think of all the public health interests or other third parties that might be interested in other research questions from a large scale data set. Yet this data is not collected with scientific processes and controls and is not treated with the rigor and scrutiny that a scientific study requires. Jawbone and other fitness trackers don’t give us the option to use their devices while opting out of contributing to the anonymous data sets they publish. Maybe that ought to change.

    The Large Hadron Migrator is a tool to perform live database migrations in a Rails app without locking.

    The basic idea is to perform the migration online while the system is live, without locking the table. In contrast to OAK and the facebook tool, we only use a copy table and triggers. The Large Hadron is a test driven Ruby solution which can easily be dropped into an ActiveRecord or DataMapper migration. It presumes a single auto incremented numerical primary key called id as per the Rails convention. Unlike the twitter solution, it does not require the presence of an indexed updated_at column.

  • Biased Locking in HotSpot (David Dice’s Weblog)

    This is pretty nuts. If biased locking in the HotSpot JVM is causing performance issues, it can be turned off:

    You can avoid biased locking on a per-object basis by calling System.identityHashCode(o). If the object is already biased, assigning an identity hashCode will result in revocation, otherwise, the assignment of a hashCode() will make the object ineligible for subsequent biased locking.

  • Archie Markup Language (ArchieML)

    ArchieML (or “AML”) was created at The New York Times to make it easier to write and edit structured text on deadline that could be rendered in web pages, or more specifically, rendered in interactive graphics. One of the main goals was to make it easy to tag text as data, without having type a lot of special characters. Another goal was to allow the document to contain lots of notes and draft text that would not be read into the data. And finally, because we make extensive use of Google Documents’s concurrent-editing features — while working on a graphic, we can have several reporters, editors and developers all pouring information into a single document — we wanted to have a format that could survive being edited by users who may never have seen ArchieML or any other markup language at all before.

  • California Says Motorcycle Lane-Splitting Is Hella Safe

    A recent yearlong study by the California Office of Traffic Safety has found motorcycle lane-splitting to be a safe practice on public roads. The study looked at collisions involving 7836 motorcyclists reported by 80 police departments between August 2012 and August 2013. “What we learned is, if you lane-split in a safe or prudent manner, it is no more dangerous than motorcycling in any other circumstance,” state spokesman Chris Cochran told the Sacramento Bee. “If you are speeding or have a wide speed differential (with other traffic), that is where the fatalities came about.”

[....] HP has filed several patents covering standard Continuous Delivery (CD) practices. You can help to have these patents revoked by providing ‘prior art’ examples on Stack Exchange.
    In fairness, though, this kind of shit happens in most big tech companies. This is what happens when you have a broken software patenting system, with big rewards for companies who obtain shitty troll patents like these, and in turn have companies who reward the engineers who sell themselves out to write up concepts which they know have prior art. Software patents are broken by design!

  • Why are transhumanists such dicks?

    Good discussion from a transhumanist forum (via Boing Boing):

    “I’ve been around and interviewed quite a lot of self-identified transhumanists in the last couple of years, and I’ve noticed many of them express a fairly stark ideology that is at best libertarian, and at worst Randian. Very much “I want super bionic limbs and screw the rest of the world”. They tend to brush aside the ethical, environmental, social and political ramifications of human augmentation so long as they get to have their toys. There’s also a common expression that if sections of society are harmed by transhumanist progress, then it is unfortunate but necessary for the greater good (the greater good often being bestowed primarily upon those endorsing the transhumanism). That attitude isn’t prevalent on this forum at all – I think the site tends to attract more practical body-modders than theoretical transhumanists – but I wondered if anyone else here had experienced the same attitudes in their own circles? What do you make of it?”

  • JClarity’s Illuminate

    Performance-diagnosis-as-a-service. Cool.

    Users download and install an Illuminate Daemon using a simple installer which starts up a small stand alone Java process. The Daemon sits quietly unless it is asked to start gathering SLA data and/or to trigger a diagnosis. Users can set SLA’s via the dashboard and can opt to collect latency measurements of their transactions manually (using our library) or by asking Illuminate to automatically instrument their code (Servlet and JDBC based transactions are currently supported). SLA latency data for transactions is collected on a short cycle. When the moving average of latency measurements goes above the SLA value (e.g. 150ms), a diagnosis is triggered. The diagnosis is very quick, gathering key data from O/S, JVM(s), virtualisation and other areas of the system. The data is then run through the machine learned algorithm which will quickly narrow down the possible causes and gather a little extra data if needed. Once Illuminate has determined the root cause of the performance problem, the diagnosis report is sent back to the dashboard and an alert is sent to the user. That alert contains a link to the result of the diagnosis which the user can share with colleagues. Illuminate has all sorts of backoff strategies to ensure that users don’t get too many alerts of the same type in rapid succession!

    Holy shit. Gemalto totally rooted.

    With [Gemalto's] stolen encryption keys, intelligence agencies can monitor mobile communications without seeking or receiving approval from telecom companies and foreign governments. Possessing the keys also sidesteps the need to get a warrant or a wiretap, while leaving no trace on the wireless provider’s network that the communications were intercepted. Bulk key theft additionally enables the intelligence agencies to unlock any previously encrypted communications they had already intercepted, but did not yet have the ability to decrypt. [...] According to one secret GCHQ slide, the British intelligence agency penetrated Gemalto’s internal networks, planting malware on several computers, giving GCHQ secret access. We “believe we have their entire network,” the slide’s author boasted about the operation against Gemalto.

  • One year of InfluxDB and the road to 1.0

    half of the [Monitorama] attendees were employees and entrepreneurs at monitoring, metrics, DevOps, and server analytics companies. Most of them had a story about how their metrics API was their key intellectual property that took them years to develop. The other half of the attendees were developers at larger organizations that were rolling their own DevOps stack from a collection of open source tools. Almost all of them were creating a “time series database” with a bunch of web services code on top of some other database or just using Graphite. When everyone is repeating the same work, it’s not key intellectual property or a differentiator, it’s a barrier to entry. Not only that, it’s something that is hindering innovation in this space since everyone has to spend their first year or two getting to the point where they can start building something real. It’s like building a web company in 1998. You have to spend millions of dollars and a year building infrastructure, racking servers, and getting everything ready before you could run the application. Monitoring and analytics applications should not be like this.

Well, this means that those dodgy certificates aren’t limited to Lenovo laptops sold over a specific date range.

  • Vaurien, the Chaos TCP Proxy — Vaurien 1.8 documentation

    Vaurien is basically a Chaos Monkey for your TCP connections. Vaurien acts as a proxy between your application and any backend. You can use it in your functional tests or even on a real deployment through the command-line. Vaurien is a TCP proxy that simply reads data sent to it and pass it to a backend, and vice-versa. It has built-in protocols: TCP, HTTP, Redis & Memcache. The TCP protocol is the default one and just sucks data on both sides and pass it along. Having higher-level protocols is mandatory in some cases, when Vaurien needs to read a specific amount of data in the sockets, or when you need to be aware of the kind of response you’re waiting for, and so on. Vaurien also has behaviors. A behavior is a class that’s going to be invoked everytime Vaurien proxies a request. That’s how you can impact the behavior of the proxy. For instance, adding a delay or degrading the response can be implemented in a behavior. Both protocols and behaviors are plugins, allowing you to extend Vaurien by adding new ones. Last (but not least), Vaurien provides a couple of APIs you can use to change the behavior of the proxy live. That’s handy when you are doing functional tests against your server: you can for instance start to add big delays and see how your web application reacts.

  • Embed-able Computers are a Thing. — February 12, 2015

    ‘If it works, a copy of Burgertime for DOS is now in your browser, clickable from my entry. If it doesn’t… well, no Burgertime for you. (Unless you visit the page.) There’s a “share this” link in the new interface for sharing these in-browser emulations in web pages, weblogs and who knows what else.’

  • China’s Internet Censors Now Have Their Own Theme Song, And It Is Glorious – China Real Time Report – WSJ

    According to a report posted Thursday to the website of the state-run China Youth Daily, the Cyberspace Administration of China choral group this week unveiled a new song, “Cyberspace Spirit,” glorifying the cleanliness and clarity of China’s uniquely managed Internet. The song, an orchestral march built around a chorus that proclaims China’s ambition to become an “Internet power,” opens with lyrics describing celestial bodies keeping careful watch over the sky. From there, the lyrics conjure more vivid imagery, comparing the Internet to “a beam of incorruptible sunlight” that unites “the powers of life from all creation.”

  • Automating Tinder with Eigenfaces

    While my friends were getting sucked into “swiping” all day on their phones with Tinder, I eventually got fed up and designed a piece of software that automates everything on Tinder.
    This is awesome. (via waxy)

  • RateLimitedLogger

    Our latest open source release from Swrve Labs: an Apache-licensed, SLF4J-compatible, simple, fluent API for rate-limited logging in Java: ‘A RateLimitedLog object tracks the rate of log message emission, imposes an internal rate limit, and will efficiently suppress logging if this is exceeded. When a log is suppressed, at the end of the limit period, another log message is output indicating how many log lines were suppressed. This style of rate limiting is the same as the one used by UNIX syslog; this means it should be comprehensible, easy to predict, and familiar to many users, unlike more complex adaptive rate limits.’ We’ve been using this in production for months — it’s pretty nifty ;) Never fear your logs again!
