Two weeks in a row! This week’s DLTJ Thursday Threads looks at how Twitter changed its timeline functionality to include things that it thinks you’ll find interesting. Next, for the academic libraries in the audience, is a report from the New Media Consortium on trends and technologies that will libraries will likely encounter in the next five years. Lastly, news about research into how USB devices can spread malware in ways we can’t detect.

Your Twitter Timeline is No Longer Your Own

Twitter recently began adding tweets to your timeline that have been favorited by people you follow. The decision has been a controversial one, but it looks like it’s here to stay. Twitter has now formally changed its definition of your home timeline to note that it will add in content that it thinks you’ll want to see.

Additionally, when we identify a Tweet, an account to follow, or other content that’s popular or relevant, we may add it to your timeline. This means you will sometimes see Tweets from accounts you don’t follow. We select each Tweet using a variety of signals, including how popular it is and how people in your network are interacting with it. Our goal is to make your home timeline even more relevant and interesting.

What’s a Twitter timeline?, Twitter Help Center

Twitter was one of the last social network holdouts to not mess with its basic formula of what it showed you: what you saw in your timeline was based directly on who you subscribed to. (Well, we’ll ignore the sponsored tweet program for the moment.) As The Next Web points out, Twitter has changed the definition of “What’s a Twitter timeline?” page to include the second quote above. This isn’t full-blown filtering — Twitter is not (yet?) deciding to remove uninteresting tweets from your timeline. It is trying to show you other things that you may be interested in, though.

When I posted an earlier article from The Next Web on LinkedIn about this change, Steve Casburn noted the Medium article The downside of algorithmic filtering. That article pointed out that while the author’s Twitter timeline was full of tweets about the police shooting and later civil unrest in Ferguson, her Facebook wall was not — it had not made it through the algorithmic exclusion filter that Facebook put in place. The author goes on to ask, “what if Ferguson had started to bubble, but there was no Twitter to catch on nationally? Would it ever make it through the algorithmic filtering on Facebook? Maybe, but with no transparency to the decisions, I cannot be sure.”

I get that Twitter is trying to increase its “stickiness” by showing us things that it things will hold our interest right in line with things that we ask for. I hope that Twitter doesn’t decide to remove things that it things won’t be interesting to us. That would change the nature of Twitter dramatically and reduce its usefulness of getting outside of the “filter bubble.” (Interestingly, I’ve yet to see this new behavior myself in either Tweetdeck or the Twitter website.)

A Glimpse at the Future: The Library Edition of the Horizon Report

The NMC Horizon Report: 2014 Library Edition, examines key trends, significant challenges, and emerging technologies for their potential impact on academic and research libraries worldwide. While there are many local factors affecting libraries, there are also issues that transcend regional boundaries and common questions; it was with these questions in mind that this report was created. The NMC Horizon Report: 2014 Library Edition was produced by the NMC in collaboration with University of Applied Sciences (HTW) Chur, Technische Informationsbibliothek (TIB) Hannover, and ETH-Bibliothek Zurich. To create the report, an international body of experts from library management, education, technology, and other fields was convened as a panel. Over the course of three months in the spring of 2014, the 2014 Horizon Project Library Expert Panel came to a consensus about the topics that would appear here in the NMC Horizon Report: 2014 Library Edition.

For 12 years, the New Medium Consortium (NMC) and the EDUCAUSE Learning Initiative (ELI) partnered to create the Horizon Report on higher education, a document that brings together practitioners to reach a consensus on emerging technologies in one-, three- and five-year time horizons. This year, NMC and others partnered to create the first report geared towards academic and research libraries. It covers topics like the evolving nature of the scholarly record and the rise of new forms of multidisciplinary research along with the adoption of technologies such as electronic publishing and bibliometrics. This document is well researched and footnoted. And if you want more depth, the project wiki is online with more details about the selected topics and other topics that didn’t filter to the top of the discussion.

USB Flash Drives as Vectors for Malware

Most USB devices have a fundamental security weakness that can be exploited to infect computers with malware in a way that cannot easily be prevented or detected, security researchers found. The problem is that the majority of USB thumb drives, and likely other USB peripherals available on the market, do not protect their firmware — the software that runs on the microcontroller inside them, said Karsten Nohl, the founder and chief scientist of Berlin-based Security Research Labs.

Most USB thumb drives can be reprogrammed to infect computers, by Lucian Constantin, InfoWorld, 1-Aug-2014

Computer users pass around USB sticks like silicon business cards. Although we know they often carry malware infections, we depend on antivirus scans and the occasional reformatting to keep our thumbdrives from becoming the carrier for the next digital epidemic. But the security problems with USB devices run deeper than you think: Their risk isn’t just in what they carry, it’s built into the core of how they work.

Why the Security of USB Is Fundamentally Broken, by Andy Greenberg, Wired Threat Level blog, 31-Jul-2014

Can you trust that USB flash drive? Arguably, no. The problem lies in the software that runs on the flash drive itself. Called the “firmware” it is that software that can be changed to, say, implant malware into files that are copied to and from the flash drive. Or the flash drive could be programmed to emulate a keyboard and “type” nefarious commands to the operating system. Or, most ingeniously in my mind, emulate a network adapter in such a way as to silently redirect all of you internet requests through a bad guy’s server.

Why has USB become the main way to connect peripherals to computers? Why hasn’t anything replaced it? Ars Technica has an in-depth article on the history of USB and other connectors that have tried to displace it.

Thursday Threads: Developer Genders, Facebook Release Engineering, Alcohol Among Technologists

You’ll get the sense that this week’s Thursday Threads is stacked towards cultural awareness. First is the view of a developer of the female gender in a room of peers at a meeting of the Digital Public Library of America. The second thread is a pointer to a story about Facebook’s software release process, and it leads into a story about the role of alcohol in technology conferences and reflections from the library technology community.

DLTJ Thursday Threads is a weekly summary of technology, library, and publishing topics (and anything else that crosses my path that is worth calling out).

An Inclusive Table

But here I am, with a constant background obsession, now, of how to get more librarians involved (and involved more deeply) in tech, how to foster collaboration on library technology projects, which is inseparable from the problem of how to get more women involved more deeply and collaboratively in technology. So I can’t not look at that room and see how the status lines fracture, along code mastery but coincidentally also gender, written in the physical geography of the room, where I’m the only one sitting at the table. I can’t not wonder, how can I create spaces which redraw those lines.

Andromeda attended the DPLA hackathon last Thursday and posted this very pointed view of the perceptions of women in library technology.

A Behind-the-Scenes Look at Facebook Release Engineering

I recently had a unique opportunity to visit Facebook headquarters and see that story in action. Facebook gave me an exclusive behind-the-scenes look at the process it uses to deploy new functionality. I watched first-hand as the company’s release engineers rolled out the new “timeline” feature for brand pages.

That was where I met Chuck Rossi, the release engineering team’s leader. Rossi, whose workstation is conveniently located within arm’s reach of the hotfix bar’s plentiful supply of booze, is a software industry veteran who previously worked at Google and IBM. I spent a fascinating afternoon with Rossi and his team learning how they roll out Facebook updates—and why it’s important that they do so on a daily basis.

I’m pointing to this story for two reasons. First, it is a fascinating look at how one of the top internet operations manages its processes for rolling out new software. Second, how the wheels of the release process are greased feeds into the third story below.

Our Culture of Exclusion

Lately there have been a lot of great articles being written and discussion happening around sexism in the tech industry. And the flames are being fanned by
high profile incidents of people saying and doing just plain stupid things.

It reminded me of this draft post just sitting here, uncommitted. For quite a while I’ve been collecting links, tweets and other stuff to illustrate another problem that’s been affecting me (and other people, surely). I thought it was finally time to write the post and bring this up because, honestly, I feel excluded too.

Our Culture of Exclusion, Ryan Funduk’s blog

The role of alcohol in technology events was a topic of discussion on Twitter and elsewhere at the end of last week. There is a term for this that I heard for the first time last week — brogrammer — and I don’t think it is a flattering persona for the technology profession. The way in which Facebook releases its code, described in the thread above, is one data point. Ryan’s message, quoted above, points to some high-profile conferences where alcohol seems to play a central part of the event. His article was the source of some introspection among the Code4Lib community as well.

Code4Lib Discussion of "Culture of Exclusion"

Prompted by Ryan Funduk’s "Culture of Exclusion" post ( about the prevelance of alcohol and alcohol extremes at technology conferences, members of the Code4Lib community pondered what this means for our own events.

2 takes of ppl who don’t drink at conferences: and I’m personally more inclined to @scalzi’s.John Mark Ockerbloom
@JMarkOckerbloom Interesting to think about in terms of #code4lib, at least for me.Mark Matienzo
…but I can understand @rfunduk’s take too. Confs vary,, but at ones I go to ppl don’t give me grief for skipping the alcohol at socials.John Mark Ockerbloom
@anarchivist Haven’t made it to C4L, so can’t comment. Most confs I go to have events w alcohol, not everyone has it, & that seems fine.John Mark Ockerbloom
This post (thanks @JMarkOckerbloom!) resonated w me: I like a good cocktail, but events shouldn’t be all about drinks.Leslie Johnston
@anarchivist @JMarkOckerbloom The bringing and drinking of specialty beers is one of the most visible #code4lib activities to those outside.Leslie Johnston
@anarchivist @JMarkOckerbloom And if you’re not already in the know about cask ales or regional producers, it can feel a bit exclusionary.Leslie Johnston
@lljohnston @anarchivist @JMarkOckerbloom I’ll admit when I read that, c4l was the first lib conference that came to mindSarah Shreeves
@sshreeves @lljohnston @jmarkockerbloom the craft beer drink up (as it was in 2011 and 2012) is a recent addition. Some ppl tried it [+]Mark Matienzo
@sshreeves @lljohnston @jmarkockerbloom because it was done at other confs. Not to say alcohol centric socializing didnt at c4l before. [-]Mark Matienzo
@anarchivist @sshreeves @jmarkockerbloom I def know that. Just saying it’s become of the most visible events to non-attendees. (1/2)Leslie Johnston
@anarchivist @sshreeves @jmarkockerbloom With the planning via twitter and tweeted images of loaded suitcases and rows of empty bottles.Leslie Johnston
@lljohnston @anarchivist @sshreeves @jmarkockerbloom Also – totally not saying c4l is the only place this happens, or knocking c4l at all.Leslie Johnston
@lljohnston @sshreeves @jmarkockerbloom understood/agreed. I’m implicated as I have organized& promoted those parts. Still have concerns.Mark Matienzo
Skimming tweets about code4lib craft beer meetu. Ever concern about wine tastings at ALA being exclusionary to folks who don’t know wine?Jon Gorman
@codexmonkey I think as @lljohnston said it’s the visibility – totally agree this happens at other confsSarah Shreeves
@anarchivist @sshreeves @lljohnston @jmarkockerbloom the topic is fascinating to me. I always saw it as an inclusive, learning experience.Declan Fleming
@anarchivist @sshreeves @lljohnston @jmarkockerbloom interesting to see it cast as exclusive. Don’t like ppl feeling excluded.Declan Fleming
@lljohnston @anarchivist @JMarkOckerbloom: Fortunately folks behave well at these events. Should reinforce these are tastings not binges.Michael J. Giarlo
@lljohnston @anarchivist @JMarkOckerbloom: And I don’t react well to hearing our tastings are exclusive, so I’ll shut up at this point.Michael J. Giarlo
@anarchivist @sshreeves @lljohnston @jmarkockerbloom: Vegetarian-centric socializing happens as well though admittedly not at same scale.Michael J. Giarlo
@anarchivist @lljohnston @sshreeves @jmarkockerbloom: I agree w/ this, but some folks are extremely sensitive to alcohol & won’t be cmfrtblMichael J. Giarlo
@mjgiarlo @anarchivist @lljohnston @sshreeves @jmarkockerbloom next year: craft cheese.Dan

@mjgiarlo @anarchivist @lljohnston @sshreeves @jmarkockerbloom c4l does not condone intolerance.Dan
@JMarkOckerbloom @anarchivist I’ve been to academic conferences where alcohol is much more prevalent than in library conferences. 1/2Becky Yoose
@JMarkOckerbloom @anarchivist 2/2 There’s an academic conf where free alcohol flows for entire conf. Ex – business meetings have open bars.Becky Yoose

@anarchivist @lljohnston @sshreeves @JMarkOckerbloom why? It already sells out instantly. Obv there is a big market for current style.Jenny Reiswig
Talk of #code4lib and social reminds me I’m hoping to play some board games for #code4lib13. Lot easier to bring when driving ;-)Jon Gorman
@anarchivist @lljohnston @sshreeves @JMarkOckerbloom that’s halfway just a devils advocate reply btw.Jenny Reiswig
RE: discussions of C4L + Beer. I love the beer swaps, but think they are a bit exclusionary. No alternative gathering on same night/time [+]Tim Donohue
Maybe that handful of blog posts and tweet streams will alter human social behavior that spans cultures and generations, we’ll see.Michael J. Giarlo
Plus advertised as "come drink beer with us", rather than "come hang out & meet folks & if interested try some new beer" [-]Tim Donohue
@anarchivist @mjgiarlo @JMarkOckerbloom @declan @danwho @yo_bj Ad the super-social aspect is def one of its best qualities as a conference.Leslie Johnston

And now I’m craving fresh string cheese. Damn you, #code4lib.Becky Yoose
@mjgiarlo @danwho @jmarkockerbloom @lljohnston @sshreeves @yo_bj Honestly, I think that’s not a fair comparison, but whatevs.Mark Matienzo
Last comment on C4L + Beer. I think it’d do wonders to call it something like Code4Lib "Happy Hour" or "Social" rather than "DrinkUp"Tim Donohue
@anarchivist @danwho @jmarkockerbloom @lljohnston @sshreeves @yo_bj: It’s not. Maybe I’ve lost too many brain cells. I wonder how.Michael J. Giarlo
@mjgiarlo @danwho @jmarkockerbloom @lljohnston @sshreeves @yo_bj I blame the pork.Mark Matienzo
@timdonohue: That’s the great thing about code4lib: if anyone’s willing to step up and make that change, it’ll happen.Michael J. Giarlo
@anarchivist @mjgiarlo @jmarkockerbloom @lljohnston @sshreeves @yo_bj it hard to deconstruct an event (ritual?) that grew organically.Dan
@mjgiarlo just feedback to "owners" (usual organizers) of "DrinkUp". A bit part is just in how it is advertised. Emphasize social over beerTim Donohue
@timdonohue: No, I appreciate the feedback, Tim. Wasn’t trying to hit you with a "patches welcome." That is how #code4lib works, it seems.Michael J. Giarlo
@mjgiarlo that being said, I’m a huge fan of the craft beer parts. :)Tim Donohue
@mjgiarlo thanks for clarifying. Final thought: there is such a thing as "craft soda" too. Perhaps it need not be limited to beerTim Donohue
@timdonohue: It needn’t, I agree, and we’ve had plenty of folks bring soda, baked goods, snacks, eau de vie, etc.Michael J. Giarlo
@rfunduk Great blog post. You may be interested to know that librarians are a bit like that too. Restrained example: M.
@mjgiarlo coolio :) I didn’t realize that.Tim Donohue
Further thought: maybe ppl organize drinking events at confs to include newbies rather than have a secret clique event. @rfunduk @cazzersonEmily M.
@bradamant @rfunduk Drinking culture is prevalent beyond tech fields. I’ve been to academic confs where drinking went nonstop for days.Becky Yoose
This. RT @bradamant: Further thought: maybe ppl organize drinking events at confs to include newbies rather than have a secret clique eventMichael J. Giarlo
@bradamant @rfunduk I feel that US culture surrounding alcohol is a big perpetrator in conf drinking, but I would need to do more research.Becky Yoose
@yo_bj @bradamant @rfunduk: And it’s not just libraries, or academics. It spans industries, cultures, and generations.Michael J. Giarlo
@bradamant @rfunduk: Does that page strike you as brogrammer-y? Sure, beer is mentioned, but so is food, and nightlife, and the venue, etc.Michael J. Giarlo
@bradamant @rfunduk I also forgot to mention anime/fandom conventions. Those get dangerous fast, since there are more underage attendees.Becky Yoose
@mjgiarlo @bradamant @rfunduk Yep. For non-drinking folks like myself, I’m sometimes left scratching my head wondering how it got to this.Becky Yoose
@yo_bj @mjgiarlo @bradamant @rfunduk I think a lot of people just don’t have enough socializing in their day to day lives…Alexander O’Neill
@yo_bj @mjgiarlo @bradamant @rfunduk … So conferences full of people who ‘get’ them and no family, etc., are a temping chance to cut looseAlexander O’Neill
Following discussion about alcohol at conferences and in particular @code4lib. Could ppl add to with their thoughts?Margaret Heller
@alxp @yo_bj @bradamant: I’m also not convinced what @rfunduk wrote about happens at e.g. #code4lib. Different phenomenon.Michael J. Giarlo
@alxp @yo_bj @bradamant @rfunduk: Can we please hashtag this #brewhaha?Michael J. Giarlo
Uncomfortable at a bar? Fashion your own teetotaler conf culture instead of advocating the destruction of another.
@mjgiarlo @yo_bj @danwho @anarchivist @sshreeves @jmarkockerbloom We do tend to grouse, it’s true.Leslie Johnston
@mjgiarlo @yo_bj @rfunduk Whoa, back from lunch! Good convo. I don’t think c4l is totally like that, but of all confs I attend: the most.Emily M.
@FeedJoelPie My feed is also talking about it, but for library code conferences.Margaret Heller
@mjgiarlo @yo_bj @rfunduk I’m no teetotaller, but find the seeming necessity of mentioning alcohol arrangements odd. Alcohol != socializing.Emily M.
@bradamant @yo_bj @rfunduk: Not sure which context you’re referring to here, "ours" (e.g. code4lib) or the IT brogrammer one.Michael J. Giarlo
@mjgiarlo @yo_bj @rfunduk Finally, re: expections and alcohol, I loved this article: M.
@mjgiarlo @yo_bj @rfunduk What I’m mulling is that a cross-profession culture/expectation of drinking is being reflected at prof events.Emily M.
@bradamant @yo_bj @rfunduk: I remember feeling quite alienated as a teetotaler (’til I was 26), till I realized I excluded *myself*.Michael J. Giarlo
@bradamant Now that I’ve read @rfunduk ‘s post I feel that those elements of C4L may come from code conference world a bit.Margaret Heller
@bradamant I wrote some of the copy on that page, but I want to make sure ppl have other low key social events. Hope to do cookie baking!Margaret Heller
@Margaret_Heller @bradamant At the Medical Library Association there’s a ton of drinking as well, but generally at vendor parties.Jenny Reiswig
@Margaret_Heller @bradamant a lot of folks do like a drink when they socialize. Not gonna lie, I’m one of them.Jenny Reiswig
@Margaret_Heller @bradamant But I do agree it needs to be optional and not expected, or the only social option.Jenny Reiswig
@Margaret_Heller @bradamant Most of the folks I know who drink at confs drink just as much at home. Not gonna lie, that’s me too.Jenny Reiswig
@jenfoolery @bradamant I agree & certainly I do drink socially and at home. But do worry about unhealthy culture this encourages.Margaret Heller
@jenfoolery @bradamant which is to say, I’ve ended up getting more drunk around professional colleagues than my friends, which is weird.Margaret Heller
@jenfoolery @bradamant And probably due to a) shyness b) enjoying parties and c) wanting to fit in d) all of the above.Margaret Heller
@jenfoolery @Margaret_Heller MLA parties feel different to me. Maybe I don’t go to the good ones? Alcohol perfunctory, not selling point?Emily M.
@bradamant @Margaret_Heller I haven’t been to MLA since about 2003… maybe it’s calmed down. I remember some crazy Ovid parties.Jenny Reiswig

This week’s DLTJ Thursday Threads is about data centers — those dark rooms with all of the blinking lights of computers doing our bidding. Data centers hit the mainstream news this week with the outage at one of Amazon’s cloud computing clusters. And since computers and their associated peripherals consume a lot of energy, researchers are proposing to run data centers on renewable energy. And finally Facebook and Google release separate videos that give glimpses into how large data centers are run.

Amazon EC2 Outage Hobbles Websites

Amazon Web Services’ Elastic Compute Cloud, which offers computation as a service to thousands of businesses, and its Relational Database Service, began experiencing errors shortly before 2 a.m. PDT on Thursday at Amazon’s US-EAST data center in Virginia and the service interruption has been ongoing for more than nine hours now.

The technical problems have slowed or disabled access to the websites of customers utilizing AWS US-East resources, including Engine Yard, Foursquare, Hootsuite, Heroku, Quora, and Reddit, to name a few.

Amazon EC2 Outage Hobbles Websites, by Thomas Claburn, InformationWeek

Failures of Amazon’s Elastic Compute Cloud service — think of it as renting virtual computer servers somewhere out there on the internet — last week caused major internet sites to shut down. As of this writing, the root cause analysis hasn’t been published, but signs are pointing to a cascade of events starting with a minor failure that snowballed into system overload as the rented servers tried to restart themselves in other areas of Amazon’s cloud capacity. The questions being raised though are leading to a darkening of the puffy white cloud computing promise. Ultimately, though, use of computing in the cloud seems to be a trade-off where you can save money by not owning your own computing infrastructure with the downside that you don’t have as much control when something goes wrong.

Far-flung Data Centers Could Use Otherwise Unharvestable Renewable Energy For Computation

Researchers at Cambridge University want to put data centers in places so remote they aren’t on any power grid. Their models indicate that moving data-hungry computation to places such as scorching deserts, windswept peaks, and the middle of the Atlantic Ocean — all rich in sunlight and wind energy — could allow this otherwise unharvestable energy to do useful work.Really Remote Data, by Christopher Mims, MIT Technology Review

The second thread comes by way of MIT Technology Review and points to a paper by Sherif Akoush, Ripduman Sohan, Andrew Rice, Andrew W. Moore and Andy Hopper — all of Cambridge University called Free Lunch: Exploiting Renewable Energy For Computing, to be presented at the USENIX-sponsored the 13th Workshop on Hot Topics in Operating Systems next month. The “Free Lunch” part comes from using renewable energy sources at these various locations to power data centers where compute jobs are shuffled around the locations depending on the available energy — and consequently computing capacity — at each center. A neat idea, and one that is probably valuable for compute-intensive jobs like video conversion and data mining.

What Goes Into Running Large Data Centers

Facebook’s Open Compute Project

Google’s Data Center Security

Inspired by the model of open source software, we want to share the innovations in our data center for the entire industry to use and improve upon. Today we’re also announcing the formation of the Open Compute Project, an industry-wide initiative to share specifications and best practices for creating the most energy efficient and economical data centers.>

This video tour of a Google data center highlights the security and data protections that are in place at our data centers.

For two entirely different purposes, Facebook and Google released videos recently that give glimpses into what each does to run a data center. The four-and-a-half-minute Facebook video introduces us to their Open Compute Project: a set of plans for server hardware and for physical buidings to creating the most efficient computer clusters possible. In the seven-minute Google video, we see part of what Google does to keep data safe that is stored in the cloud (including a pair of hard drive crushing machines!).
