Yeah, my reaction to most of these sorts of articles is "lawl, handwriting." Even on my Note 3, it's usually faster for me to type by tapping on Hacker's Keyboard than to use handwriting recognition (even if the recognition were perfect) and a lot of people seem to find Swyft-style keyboards really efficient. Eventually I think handwriting will go away just about entirely, and all that will remain will be reserved for moments like in The Diamond Age when a character is taken aback at the quality of an invitation's Chinese calligraphy, and the fact that it's used is more for a status symbol of being able to learn such an unnecessary art and perform it well than for anything else.
This one has a serious flaw:

Hawaii in particular seems like an insane place to build a car-centric society. It’s not like anyone is going to go on a long road trip, or needs to commute from point to point over a huge geographic area (as one comparison, the island of Oahu has <1/10 the area of the SF Bay Area). I’m guessing the typical Honolulu commute is only a few miles.

Some combination of boats, mass transit, bikes, walking, so-called neighborhood electric vehicles, and the occasional jeep seems like it would be much more practical. The money and space spent on parking, wide streets, and car ownership would go quite a long way if diverted to transit.

In addition to just being a nice monospaced font, I like that its non-monospaced version, Ubuntu, is also available. I can use Mono in my source and non-Mono in my desktop UI and everything looks consistent.
"lets me express myself faster than a couple of quick doodles on a piece of paper."

... and then take a digital photo. Which is the process I've adopted. This is a hard problem to solve with the clumsy digital tools we have at our disposal at the moment. Probably not with this generation of input.
I wondered that, too. It seemed like it was just absentmindedly forgotten to be mentioned. On a second, closer read, I realized that it was actually a design issue. The default text was chosen to be grey, and the link text color to be dark blue-grey. Essentially, links are indistinguishable from the text they are interspersed with. If you click the link and jump to it when you see it in the first paragraph, you'll find further details. "As you know, Stefan H from Ericson R&D, and Chair of the webrtc working group @ w3c and myself have been instrumental in starting the webrtc in webkit initiative[THAT WAS THE LINK!]."

...it gives you this:

"WebRTC is a set of browser APIs and protocols being worked on by the W3C and IETF standardization bodies. With WebRTC, developers can quickly add real-time peer-2-peer audio, video and data capabilities to their web applications through a set of standardised JavaScript APIs.

WebKit today lacks support for this exciting new standard. Our intention is to add WebRTC support to WebKit, starting with the WebKit GTK+ port (Linux), by means of the OpenWebRTC implementation. Much of the WebRTC support will be implemented in the core of WebKit and therefore shared among all WebKit ports. This will also enable integration of other WebRTC backends such as webrtc.org."

It would have been nice if that had just been summarized and added into the post though. It's kind of annoying to have to jump around to a bunch of different places when all you're trying to do is soak up information quickly and move on to the next thing. It really pulls you out of the flow of the article, gets you out of the mindset of "I'm just sitting here reading an article." (into something more like "now here's a 1. visual puzzle where I have to figure out which elements are clickable, and 2. one too many click-throughs and back-buttons, figuring out where I was back on the main page, and trying to resume reading.
For block diagrams, graphviz is the fastest for me. If I need anything more complicated than node->node relations, pretty much any editor akin to visio is still faster than doing it by hand and looks much prettier because I have infinite space and can rearrange things on the fly. By hand is useful when all I have for collaboration is a whiteboard, though.

Most of the now-approximate rhymes in classic English poets were precise at the time the poems were written, but got dislocated as pronunciations shifted.

In some cases no one really knows whether the rhymes were originally precise. See this pretty neat Language Log thread (read the comments—skip the top post) about Pope's "obey/tea" and Blake's "eye/symmetry": http://languagelog.ldc.upenn.edu/nll/?p=1421

Yep. Look into digital evidence or "e-evidence". Both are big topics in crime scene investigations and many law enforcement agencies and courts have established procedures for handling. There is ample discussion.
I agree with this. Good ideas almost never come all at once and often need to be worked on over a long time period. In the end though what matters is not how long, or how much effort it took, but how good the idea is.

Hmm, I think the range coder used in VPx is basically just an arithmetic coder with the labels changed. It's not any less efficient.

Also, JPEG and LZMA have arithmetic coders with no current patent claims. CABAC just has specific patents.

CABAC is not good on CPUs anyway - it's only fast on hardware due to using lookup tables in the critical path.
Can AI Win the New Yorker Caption Contest?
No way. I don't know how our remote working team would live without slack. It adds back the in-office style communication you have in the real workplace and (more importantly) gives us a sense of culture that is sorely lacking in a remote working environment. It's an essential tool - it's IRC with the missing bits like search, website preview, file uploads and more. We've become heavily reliant on it and even spin up consulting companies on our slack with access to specific channels and that works well too.

If you want to avoid distraction, just avoid distraction by unplugging. Turn off your phone, turn off slack notifications, lock your office door, hit the Adderall, etc. (Joking about the adderall)
Have you read Falen's translation? I think he's the best translator of Pushkin into English.
You can't argue with Poettering. He writes technically superior solutions for extremely edge-case problems and then markets them fiercely, dismissing people as stupid if they prefer the caveman's way [e.g. UNIX]. To disagree is to say you prefer a kludgy unintelligent mess. Which, we do. But you don't win points in a feature-comparison pissing contest for that.

Theo is basically who Poettering would be if he forked Linux (and was less whiny). He probably hasn't because it would be a ton of work and few people would use it, and he couldn't benefit from the base of support of the Linux ecosystem. There's a lot of crap out there that's Linux-only now, or officially only supports certain distros. It makes much more sense to convince someone to shoehorn your code into their distro than to make your own.

Few desktop users ever notice it, most server admins aren't really that knowledgeable, and most devs just write userland code. I think most people don't think about how much more of a headache things have become. After all, hasn't Linux/UNIX always been a headache, relatively speaking?

From my experience, scientists, -at least in biology, where like in sociology you might have a lot of noise to deal with-, have an internal intuition that a single paper with a significant result does not mean that we have found the truth. The recent study which reported a reproducibility in sociology of about 36% strikes me as pretty accurate.

I think the scientific system can work with that. It means that if you build follow-up experiments based on a single paper there is a good chance that the experiment fails. In some way, the scientific system of publishing is self-correcting in this regard, because you can then cast doubt on the previous paper, which is easier to publish than if you only have a fresh negative result (p-value > threshold).
The "linkbait" comment reflects one of my triggers and the way in which writing on mobile may correlate with lower quality output on my part. As original posted the line had both "linkbait" and "amateur hour". If I'd been sitting at a keyboard rather than touch screen, I might have have written something more constructive. The rhythm is better, editing is easier, and input is not so painful that I am looking for an ending after a couple of paragraphs.

Objectively speaking, there is pretty strong evidence to support a belief that a "Windows bashing meme" exists to the extent that any meme can exist. Apple spent most of a decade and several billion dollars on buying over the air advertising for it's "I'm a PC campaign"; it's so socially acceptable to bash Windows that PG hisself engaged in it for many years; and a lynchpin of Silicon Valley mythology is NetScape got hosed even though it unicorn exited at about $10 Billion, Marc Andreesen's minority stake was enough to make him a VC and Jim Clark bought a gridiron football field length yacht.

It's not that I'm opposed to over-enthusiastic headlines, well written headlines should capture the reader's attention to the point that they click. What makes it "linkbait" to me is that it panders toward confirmation bias rather than encouraging curiosity: it's us-versus-them tech gossip of the sort that tends not to make people smarter. I often wonder about unicorns not seen because of YC's historical attitude toward Windows [e.g. the days when a tock processor announcement for the mid-year Macbook dominated the HN frontpage for a day or two].

As to the other topic, one form low quality HN comments [1] take is what I call "the internet pick apart". Break a post down into many sound-bites. Cast each into an unfavorable context. Then arbitrarily argue against each sound bite. The goal is to broaden the flame war across many fronts without creating a concentrated target for coherent rebuttal. The pattern is to apply it recursively to each of successive defence by the victim. The sport is to keep the target spinning [there are extra points for reintroducing sound-bites from higher in the thread].

That said, a comment that literally begins with the string "The problem with you" probably isn't intended to produce constructive dialog. Pig lipsticking it with "r argument" doesn't change the purpose. Credit where credit is due, at least the comment works its way up to the pick apart rather than down to the problem with me.

Anyway, whenever I find myself writing or saying "you" in a conversation I try to stop and try to rephrase. It's loaded. When I read comments that use "you" it's usually the rest of the internet seeping into HN. The exception is things like "You can safely assume that I didn't write this on mobile."

[1]: On the other hand, the internet pick apart and other forms of flaming and trolling and pointless arguing constitute some of the highest quality writing on the internet in general. Trolling and flaming are successful because they are writing for an audience and for entertainment and for the shear joy of writing...or at least it was for me.
The most common concerns are a result of the font being monospace.

In most proportional fonts, 1 has a hat, and l is a vertical line; and 0 is a thin, squared off oval; while O is almost a circle. The characters become similar in monospaced typefaces so that they can fill the rectangle they're supposed to fill.

I and l are often indistinguishable; but there's no shortage of fonts that put the extra strokes onto I [eg: Verdana, Tahoma, every serif font...]
For context, Wilson and Nabokov were friends, but this was a nearly suicidal literary gesture by Wilson, whose Russian was as shaky as his judgement. Here is Nabokov training his guns on Wilson in a letter to the editor, and sending him to the bottom of the sea:

http://www.nybooks.com/articles/archives/1965/aug/26/letters...

Nabokov's Onegin translation is I believe intentionally unreadable, but as a work of scholarship it stands alone. One of the footnotes, for example, is a forty-page essay on the history of dueling.

The fact that the hive-mind plays along with this doesn't mean one should go off parroting their potential moneymakers to people who could expediently execute it before they do.

Some ideas are your potential trade secrets. Simple design patterns was enough differential for Apple to sue Samsung in April 2011, alleging it had “copied” the designs of the iPhone and iPad.

Whatever it is think twice before you you round parroting it.
This is pretty similar to my own way of managing communications.

My main concern is that this way of communicating is endangered due to mobile and walled gardens. Maybe I'm just a dinosaur.

XMPP and IRC don't seem very mobile-friendly, or at least mobile connections aren't reliable enough for them and rely on push notifications. The mobile clients (that I've tried) seem weak. Each new "innovative" communication requires yet another app I need to download and check, with communications trapped inside a proprietary client controlled by a company.
I was not, but only in retrospect. Facebook succeed by keeping the ghetto out. It really was clever to only let in people from high status universities.
There is no way to know how many people tried to build a follow-up experiment which failed and was not published because the failure to replicate will usually be assumed to be due to some mistake, and even carefully finding p > threshold is not very publishable.

When drone is up in the air at alternative controlled frequency or purely auto controlled with or without GPS - it's a bit too late.

It is an issue.
Actually a service that lets you send only 1 message a day would be very good - it would certainly cut down on the pointless work emails.

An email client or server without cc and bcc would also be great. If you want me to know something write to me directly, don’t cc me along with 200 other people.
I'd guess that the circular patterns are all because of the norm at the time being rotary dials.
Is "censored" the correct term or were rules actually broken to warrant the removal of the post? Reddit definitely faces a real challenge when subreddits are established with a name like /r/news but are self-moderated and enforce their own strict rules regarding what qualifies as news. There are tons of cases of rogue moderators but also very fair reasons for posts to be removed.

I appreciate one commenter's response:

Nick Bernabe - while I respect your work and what you're accomplishing here, not being an opinion piece isn't just about citing facts. It's also about maintaining a certain professionalism in the writing. Let the facts be persuasive, don't editorialize with statements like "Because profit, of course. Or perhaps more befittingly, theft. But you get the idea." That just diminishes the strength of what is being presented by making the author look obviously partisan and therefore easier to disregard.

It's way too easy to shout "censorship" and start coming up with conspiracy theories where mega corporations are taking control of peoples' freedom. In reality, I don't think Nestle actually cares about what anyone on Reddit's saying when we're all pseudonymous anyway. Twitter might be a different story though.

Now almost every code to be run is cache-bound for performance, not cycle-bound. So this gems, while may still work, may not be the best means to achieve optimal performance. Optimizing cache access is what brings the biggest speedups today -- see for example NumExpr[1].

Speaking of 32-bit systems with small amounts of memory, is OpenBSD being used for / developed for embedded devices, especially IoT? Given IoT devices' security issues and their minimal OS feature needs, it seems like it could be a good fit and a great opportunity for OpenBSD. (But given my minimal understanding of both, I could be way off base.)

Whole thing leads to really weird situations. I have few friends from Russia, who visited USA few times, praise it for freedoms, commerce, life, etc. Some seriously considered moving. Some - moved for good. People who mostly doing their business online (yet I know they watch TV more than I do for example.)

And these people are supporting everything propaganda is pushing.

So from outside it looks really disconcerting - on one hand they praise west, on the other - they hate it... and this hatred feel very unnatural. It is like person get second personality.

You mean MirageOS-based unikernel instances running on a L4 nanokernel running as Single-System Image on a Distributed Shared Memory machine made up of interconnected motes running the Contiki pico-OS?

Reminds me of optimizing microcode back in uni... From the reference implementation of 134 microinstructions down to 61, and it was far more cycle-efficient as well (progressive decoding and Huffman encoded micro representation given sample programs). Since it was a contest for two goals of extra credit, people were pissed that our team captured both. It took about 30 hours to implement.

Microinstructione are like a CPU's firmware which implements the external-facing macroinstruction set into a simpler set of microinstructions which coordinate various internal state.
It's obviously not any news that CIA and similar agencies sponsor disruptive activities all over the world as long as they see fit to their own interest. So-called "democracy" and "freedom" etc. are just all convenient excuses, pretext of war. Maybe the only interesting thing here is the assertion that apparently leftists don't only fight capitalists, they also fight totalitarian regimes which have long abandoned their leftist roots. This might further clarifies things a bit.
Ah well it always worked for me... may have been a case of "close enough for rock'n roll" though.
