Please be careful with the "close to C in speed" claim.

There are only a very small number of languages that can legitimately claim that (C++, Fortran, and sometimes Ada). Java is not one of them. JavaScript is surely not one of them, even with the latest versions of V8.

The only time we see performance remotely close (which still usually means several times slower, at best) to C is for extremely unrealistic micro-benchmarks that have been very heavily optimized to a state where they don't at all resemble real-world code.
Yeah. I was trying to balance more common terms and descriptiveness.

I honestly have no idea what a precise name would be. S-exps are actually a super set of these right?
I don't think you're being very fair. You're suggesting a false dichotomy.
Can you explain why it wouldn't work if it was blown in, say, 1000 pieces that would burn faster than it would burn if it was still in one piece?

Or maybe that once it's in the atmosphere there's no burning anymore?

But then what about kinetic energy loss due to air resistance? Wouldn't it work better with 1000 small pieces instead of just one piece?

And aren't 1000* (x/1000) * speed ^ 2 hits better than a single x * speed ^ 2 hit?

I'm interested and despite reading the wiki link I don't really get it.
The ambitious goals shouldn't be making a new OS then.
Posterous might not have been as big as Tumblr, but it was big. It was obvious it's management had some lack of vision, since introducing Spaces and other confusing additions.

Even with all this, it is completely confusing to me seeing it sold to Twitter and just shutting down service.

I personally will not believe to use any service made by those guys, especially Posthaven looks ridiculous in light of how Posterous got miss-managed.

Having said all this, I am not judging founders for selling out, I think they did a good thing and it is their absolutely their right, probably could've gotten way more from someone else, but it's their decision, as online user, I just can't touch anything they make.

Funny thing, I remember clicking links on HN years ago and seeing the Posterous tab in the upper right corner of my screen. But it's been a long time. It kinda brought me back to what was the not-so-distant-past.

Just one suggestion: When discontinuing a product, eliminate the link in the upper right that says "Join SPACES". It's a little thing. And nobody expects anyone to design product "un"-launches the way they design product launches.

The police are already prevented from using helicopters to collect visual information from places that would not ordinarily be visible. I can't see why drones would be any different.

I really think people are responding to the somewhat disconcerting idea of drones watching you from the air while you're out in public. Essentially, people are worried about cops having a more efficient way to do something they could legally already do: observe you while you are in public.
I am slightly annoyed from the fanboyism glorifying YC between the lines. The post is full of good advice + quotes from PG and I highly appreciate YC's contributions to the startup ecosystem but people shouldn't think that being part of YC is the only option. People like the OP telling us that they needed six attempts to get in YC send the wrong signal: that YC is the one and only way to get a real entrepreneur. PG created a great brand and yes, it must feel amazing going through YC but it could also mislead young entrepreneurs -- instead of building a great product they focus too much on the application process and potential credentials they might get from YC. You can get all the knowledge, peer pressure and get in front of any investor you want without being part of YC.
The truth about free APIs (2007)
Oh! Closure pointers would absolutely suffice. But as far as I could tell, asm.js doesn't support closure pointers either. Obviously I could use a value of "unknown" type to pass them in, but section 2.1.9 says "Since asm.js does not allow general JavaScript values, the result must be immediately coerced to an integer or double."

So I'm under the impression that asm.js can't really deal with closures or functions as values. Am I reading the docs wrong? I hope I am.
Hi Garry,

This is a simple feature request but as someone who writes occasionally it is really important to me: will I be able to customize the domain name to have it as myname.com instead of posthaven.com/myname?
You might as well use the unambiguous form, though. (And what do you do with possessives, as in "CDs' sizes"?)
Thanks for this, just signed up and started importing from Chrome, my Twitter account and RIL. =)
I'm sort of confused with the obsession some people have with applying to YC. It seems like something a lot of people do now because it is sort of prestigious and because a lot of the companies seem to do well afterwards. Maybe that's good enough, but I often feel confused reading posts like "How to get in to YC" because I'm not sure I've read one of these posts yet where the author articulates a clear reason why getting into YC was so important.

I had to babysit OS X a lot more than I had to babysit Linux. Ubuntu might take one or two tweaks when installing on a MacBook, but twenty minutes later it runs perfectly for ever (or six month, whichever comes first).

I had to babysit OS X all the time, due to its lack of a good package manager. This was years ago, I don't know if it has improved, but it grated me greatly.

To stay within sci-fi lingo, wearing a detector bracer around your arm does make you a cyborg in the same way that having an iPhone in your pocket makes you a netrunner: it sort of does a comparable job, but at the end it's clearly not a part of your body and it's always going to be an external tool.

Humans carrying tools around are awesome, but they're not cyborgs. The prospect of having a real internal augmentation is that it seamlessly and naturally becomes a part of your body. Everything else is a little bit of a cargo cult, which is sort understandable considering the lack of progress we made so far into that area of research.
Hah! Where are the Linux neckbeards now? Another day, another Linux vulnerability it seems like.

Honestly, how much longer are we going to build on this house of shaky cards?

Did they really think that letting a race condition happen on PTRACE_SETREGS was a good idea? Just for "elegance sake"? Come on.

Everyone could tell that none of ptrace/jctl callers actually want to wakeup a TASK_WAKEKILL task, but they can't specify the necessary mask.

Best replacement, wordpress?

Need to 301 everything :/
I really like this recent trend where stuff like this is getting posted and (more importantly) getting upvoted.
I know, I know... you're thinking "Why is this on HN"? Well, here's why... the S/360 is a fascinating bit of computing history that every hacker should be familiar with. For example:

System/360 was extremely successful in the market, allowing customers to purchase a smaller system with the knowledge they would always be able to migrate upward if their needs grew, without reprogramming of application software or replacing peripheral devices. The design is considered by many to be one of the most successful computers in history, influencing computer design for years to come.

and

The chief architect of System/360 was Gene Amdahl, and the project was managed by Fred Brooks, responsible to Chairman Thomas J. Watson Jr.[3]

If you don't know who Gene Amdahl and Fred Brooks are, go to Wikipedia and read up.
A lot of uses of ptrace require root on many distros, does this vulnerability work when that's enabled?

edit: as in, does yama.ptrace_scope prevent anyone without root and/or CAP_SYS_PTRACE from exploiting this?
I am 1/4 Japanese, and have the "natural" genetic version of this. It does not stop me from drinking, though I naturally drink a lot less frequently than my peers because it is unpleasant. I don't drink casually, because the pleasure of a slight buzz is overwhelmed with the discomfort of having a hot face/chest and difficulty breathing (feels a lot like a mild asthma attack - like something heavy is sitting on your chest and making it hard to take a full breath). But at a special event or a party or something, yeah, I can and will still get drunk.

Also, as almost anyone of Asian descent can tell you, you can take a Pepcid AC (or the generic equiv) around 30-45 minutes before drinking and it slows the conversion of alcohol into acetaldehyde, making drinking with this condition more tolerable.

For someone with an actual, problematic addiction to alcohol, I don't know if the side-effects of an acetaldehyde dehydrogenase deficiency will be enough to stop drinking.

What Twitter Is Actually Good For
This would have been perfect around a year ago. Once the writing was on the wall, I migrated 4 or 5 sites (kinda, mostly) to self hosted Wordpress. I would have happily shelled out $5/mth to go to posthaven, had it existed.

Because WP bugs me, I've written my own lightweight markdown based thing in node[1] that I'm gradually moving everything to.

On the upside, the Posterous thing finally taught me to not rely fully on free services, no matter how good the feature set.

It's frustrating to see these articles continue to leave out some of the most relevant parts of his work.

According to Ars Technica's interview with Swartz asking why he downloaded the JSTOR documents, he referenced his bio in the Demand Progress statement, which notes that "in conjunction with Shireen Barday, he downloaded and analyzed 441,170 law review articles to determine the source of their funding; the results were published in the Stanford Law Review. From 2010-11, he researched these topics as a Fellow at the Harvard Ethics Center Lab on Institutional Corruption."

http://arstechnica.com/tech-policy/2011/07/reddit-founder-ar...

Here is the result of his research:

http://www.stanfordlawreview.org/print/article/punitive-dama...

It found that there was extensive corruption in law journal publications which were often commissioned for specific upcoming cases.

That research work led to his position as Harvard Fellow continuing that specific work of analyzing large journal datasets to find corruption. That is why he downloaded the journals - to continue his research into analyzing large datasets to find connections that indicate corruption.

There can be no doubt that many people were unhappy about the corruption in the legal industry which he uncovered using his analysis methods. He was continuing that research on a broader scale, which he plainly indicates in his response to Ars Technica and is substantiated by his biographical, research and publication history.

As a Harvard Fellow, and as a MIT visitor, and as the son of a MIT employee visiting, he has the right to access those articles, and MIT paid for that access to JSTOR, which JSTOR had no legitimate right to withhold from a credentialed researcher with valid access. He only had to circumvent anything because JSTOR implemented access countermeasures which were contrary to their access agreement with MIT. His circumvention was only for the purpose of obtaining the access he was legally entitled to, and thus was valid.

The arguments that he was planing to redistribute articles are completely without merit and are nothing more than propaganda spread by the criminals at the Justice Department who targeted him for destruction because they are corrupt and he was someone who had already revealed systematic corruption in their legal system and published about their corruption in Stanford Law Journal.
Ask HN: Best place to find a freelance coder?
I'm looking for a coder to develop a pretty in-depth wordpress website. I have a design done, but am stuck on finding a coder. Do you have any recommendations of where I should look?
Pretty obviously joking.
COBOL ON COGS is a joke, plus I'm pretty sure a true user would get the spelling and capitalization right :) http://www.coboloncogs.org/INDEX.HTM
No, the PoC forks and ptraces the child, which is allowed in even the strictest yama settings.
Yes, ptrace can be globally disabled by a file in /proc somewhere, I believe. I forget the details.

But even with access, this is awfully hard to exploit. You need a precisely timed kill, followed by a precisely timed preemption. That's really (really) hard on a multi-cpu machine, and it's worth pointing out that the exerciser case in the bug has to patch in a sleep for the exploit to work. It's not clear if they have a real world exploit running, though of course the race is real.
Any application that has a vulnerability can run arbitrary code, such as an insufficiently patched WordPress, could enable privilege escalation using this flaw.
64 bit Chrome on Windows is a possibility, Justin Schuh is working on it https://plus.google.com/u/0/116560594978217291380/posts/d93X...
We'd also need a full widget toolkit, set of foundation/standard libraries, and all the other functionality we take for granted on other platforms.

With all that in place, then I'd use whatever reasonable (JS isn't) language existed as a norm on the platform to write applications to target the browser, instead of Android, iOS, and Max OS X.

My only allegiances are to user experience and the quality tooling necessary to ensure it. The web as-is provides neither.
Is this a vulnerability across all Linux versions or some of the more recent versions (e.g. 3.7.x)?
You should put your contact details in your profile.

If they are always on the network, it's trivial, you just boot from the network as with any other machine.

If they are often on the network, you can use occasional rsync, for example to the system partition either at boot or in the background. That way, boot is possible even if disconnected.

If they're not often on the network, and you are seriously considering doing this at all, I would reconsider which problem you are trying to solve.

Also: I don't know about anyone else here, but I would prefer not having a company manage my laptop. The use cases for such a scenario, in my view, are pretty hard to imagine.
Both 2 and 3 are certainly in the plans. How could we not have an API? And custom domains?

Brett and I have discussed #1 and it's an option we want to keep on the table. First priority is to build and create a great hosted experience, however.
Because 15 minutes a month quickly gets eaten up by writing my own monitoring scripts, and because, frankly, I don't want to. I find it boring. I do enough administrative tasks during the day to bring tedium back home. I find it an impediment to actually creating.

That's the appeal of something like posterous, even if I don't "own my presence."

The Secret of Love
The NYT review was definitely damaging to Tesla. The failure to dimensionalize li-ion power by a thermal variable is an engineering and marketing failure. On that count alone NYT review scores points. Whether or not the PR counter-punch will have sufficient weight, only time will tell. But fundamental limits of [li-ion] battery-powered electric cars are now very clearly two: (1) poor energy to mass ratio; and (2) variability/innefficiency in cold weather. The main problem with (2) is (1), which limits the ability to brute-force a solution.
It's a hard problem of course, but there are various ways to get to a partial solution. Just google patent quality metrics.
Funny you should mention that, given that I just this week had to use NEON intrinsics to eek out better user-visible wall-time performance in a native app.

I think magnetic implants count as a new sense, because after a few hours of practice, you stop being able to feel the vibrations and your brain begins to interpret the feeling as a new qualia. You really get a new sense experience as your brain interprets the new input automatically. You don't have to consciously interpret the feeling into something meaningful.

Well you can have a superconductor with no current running through it. Just charge the electromagnet with current during the scan, then bleed it off gradually when you're done. No need to turn off the superconductivity to power down the magnetism.

> 1. To describe the desired correct configuration as a directed, acyclic graph.

If you have already decided on your solution before you have analyzed the problem then there's nothing to discuss.

> 2. To have some automatic compare-and-repair mechanism regularly bring my systems to such a state.

Right. My fundamental point is that puppet-esque solutions only describe certain aspects of the system state, ultimately failing here and resulting in 'configuration drift'. Entire system images are far more elegant.

Most of the use cases I have seen for puppet-style stuff are legacy-situation based and only make sense within that context.

So what is the alternative to puppet-style solutions? Personally I use full system images on cloud and cluster solutions (corosync/pacemaker) to maintain server state.
Being in a higher tax bracket doesn't lead you to pay more tax on your initial income, only a higher rate on money above a certain threshold. That said, the article is right in that an S-Corp or LLC sound right and are rarely a good idea because you sometimes lose out on certain tax deductions because your personal income is too high. Remember though, a tax bracket is a sliding scale... see the margin tax rates table at https://en.wikipedia.org/wiki/Income_tax_in_the_United_State...
> When I started working on Posterous in 2008 ..

Just wondering: how can somebody start again something he worked already years on? I understand that you might learned a lot with Posterous and now you'd like to just employ that knowledge in a new blog project. But is it not a bit dangerous to stick to the same thing over years? You could loose time and after ten years looking back and you pity that you just worked only on blog systems. I don't want to talk blogs down, they are a very interesting use case and I still think there's room for improvement but in terms of spreading the bets and just the need to start something totally new I am a bit confused that you do the same thing over and over again (and I didn't see any disruptive feature or new angle with Posthaven).
Out of curiosity, where will you be moving the blog hosted at http://sachin.posterous.com/?
If you are never wrong, you are never interesting
