Given she published the paper and link, she should either a) take responsibility for the general availability of the materials, and b) make sure that if people email her for the materials (after finding that they're not available on Google Code) she shares them.

Don't get me wrong, I'm all for retaining the materials and knowledge, etc etc. I'm just having a hard time understanding why you expect Google to do the work and maintain it? What if she uploaded her materials to Megaupload, or any of the hundred other filesharing sites - would you hold them to the same standard? Why doesn't the journal that published the paper (which, has a revenue stream) host the material, given that it directly supports their work?
Usually by the scientific method of summing up every remotely related figure that you can find on google, adding some markup for good measure, and then maintaining a straight face while dropping it on the audience that you wish to impress.
Neat. I was also wondering if maybe it was possible to switch between two colors based on a certain ratio of frames, faster than the CRT phosphors to fully switch colors (or atleast faster than the eye could detect the swapping), such that it looks like a fractional blend between two colors based on that ratio. I remember doing this trick with the TI-85 calculator to give any degree of greyscale even though the LCD was only black and white.

Based on the links zrail mentioned, it looks like it is just a standard for sending abuse reports. The RFC looks pretty comprehensive, but there is also more information at https://en.wikipedia.org/wiki/Abuse_Reporting_Format.
The "Mandatory Typing Considered Harmful" section seemed like a lot of handwaving and threatening of bad things, but didn't describe anything I've run into at all. On the other hand, I've only been doing this for 30 years, so maybe there's all this horror waiting for me to run into... but I'm skeptical.
How about weapons that DID exist?

Private citizens owned the vast majority of the US's naval power. Namely: a substantial amount of cannonry, mortars, etc. These primitive weapons have (and had) the capability of razing cities.

Were the rockets' red glare and bombs bursting in air imaginary? No, but the home-teams' were privately owned.
I use GitHub, but I concede Bitbucket has cooler features (free private repos, password protected repos, etc). It can't beat GitHub's UI/UX and community though.
It's not unreasonable to imagine non-lethal weapons being used with far less discretion than guns. Kids running around tasing people for fun, for example.
The ad and the nature of the site is obviously the reason the page is blocked. But the page is still blocked.

If you mean to argue that this isn't a false positive, I disagree. It's just an extraordinarily hard false positive to avoid. The post and the ad shown contain no pornography but they're about pornography and other content from the same source might. None of the filters are that granular.

And that's the problem. Nobody's boss has any justifiable reason to allow their employees to read HN but not the post in question, but the burden of false positives doesn't fall predominantly on the company with the filter or even its employees. It's a negative externality that harms the author of the blocked content even though she has no ability to fix the filter.

So filters with false positives are a bug and anti-filtering proxies like Tor are the patch. Which is why everyone benefits when they're more widely deployed.
I've never been in this position so you can just throwaway my input if you want.

Some questions:

- You're burning through $60k/month. What are you spending it on if you're getting no sales? Can you cut the expenses to just focus on the necessities?

- Your co-founder is not interested in the pivot. Why not? Does he see something you don't? Maybe your side project is only getting growth because it's free. If you could "very easily" add paid models, why not try that first to see if it actually works. If it does show some promise, then I think at that time, it would be better to approach your investors as you've at least validated it a little. I don't know what the side project is but is it legit? You talk about uploading files so perhaps people are using it in a way that might be a legal grey area?

> "I have a moral issue with making money on the side while my main startup is doing so poorly"

- I'll challenge you here and say that I don't think you do have a moral issue with this. After all, you started this side project while having this startup which took away time from it so you didn't have moral objections with that. That being said, the fact that you did go out seeking something else either tells me a) you're not good at focusing on one thing in which case a startup may not be a good path for you or b) you have an inclination that the startup is not going to work in which case you should get out of it. Unless I'm missing another possibility, both options point to the same conclusion - you want to leave the startup behind.

In that case, tell your investors and give them the option that they can put the remaining money into this side project or they can have the money returned.

You keep using that word. I don't think it means what you think it means.
This Chemistry 3D Printer Can Synthesize Molecules from Scratch
This is a refreshing article considering the mainstream upsell of the selfish "cool" stone-hearted asshole.

Anywho, I used to be one of those kids with little to no capacity for empathy. I wasn't horrible, I would never have hurt anyone, but I had a really hard time relating (nor was I trying to). My pre-school teacher mentioned to my parents that something was off with me (they just thought I was a weird kid), it seemed I had no notion of social feedback, putting me somewhere on the autism spectrum.

Turns out I was going completely deaf, which on the long run ended up being a blessing in disguise (also because I more or less recovered my hearing later on).

Being deaf, you learn to read people as if they came with an instruction booklet, it comes very naturally. I saw how other people had those reactions, emotions showing in their faces, their body language and so on, and how it affected others. I started feigning it and playing with it, effectively manipulating people into reacting the way I wanted them to.

As time moved on, some of these things started coming naturally and it soon hit me like a brick: the best way to get things from others is to understand where they stand emotionally and to show reciprocation and support, i.e. empathy.

It often makes me wonder whether empathy is purely an acquired trait, or if some people have a strong predisposition for it.

The one major drawback of empathy, in my opinion, is feeling utterly useless when you see other people repeatedly hurting themselves, usually thinking they're doing the right thing. It pains me, deeply, but I suppose it's a necessary side-effect.

There's also the fact that standard format is constantly changing, and that adds a huge effort in being up-to-date with the cards, the metagame, etc.

Playing Standard is actually quite demanding, while Legacy/Vintage changes in a much slower pace, making it great for people that likes to play from time to time to "the same game they already know".

WebGL should never have been invented, at least on current architectures. It's a ticking bomb, precisely for the reasons this articles explored - drivers are complex and buggy black boxes that lie in kernel space so ring 0 access is never too far from reach for many exploits. WebGL has a potential to be exploit vector much more severe than what we've seen with other auxiliary web technologies like JavaScript or Java applets. Why not confine web to (mostly) nicely behaved x86 VMs?
I'm not sure that's really true in CS. If you're not UCB, Stanford, CMU, or MIT, you're not a "top" CS dept whether public or private. Georgia Tech, U of Washington, UC San Diego, UIUC, UCLA, UT Austin are all credibly somewhere in the top 20.
What's wrong with BD-R?
Melting Permafrost (2011)
A fun one in C is:

for(int i = 0; i < strlen(s); i++)
doSomething(s[i]);

strlen() searches for the terminating NUL byte and is thus O(n), which makes the loop quadratic.

What makes this especially fun is that strlen is part of the standard library and has defined semantics. That means the compiler is free to hoist the strlen call out of the loop if it can prove that it wouldn't alter the standards-specified behavior, like if you never modify the contents of the string. That means your asymptotic performance will depend on which compiler you're using and even which optimization level you're using.
Empathy is a skill and a talent. I've had close personal relationships with a few great salesmen. It's incredible to watch the difference between someone who is gifted in this regard and someone who isn't. It can be worked on, but some people definitely have a natural talent.

Great salesmen are always in a good mood, never negative, never criticize, never go off on random tangents and know what the other person is going to say even before they say it. They can tell immediately how a target market will react to anything in a product or offering. It's like they can easily put themselves in the other person's mindset to understand their gut emotional reaction to things. I only dream of being that good. The best I can do is to clumsily emulate it, but it requires concentration to pay attention to everything, it's like speaking a foreign language but never quite thinking in it.
Just to be clear, just because something isn't optimal doesn't mean its not worth being a part of. You can be critical and not leave at the same time. Actually, the ones who stay are the critical ones who have hopes (founded or not) that the system can improve.

Somebody else did have a usenet archive - Google bought them, mashed up a bunch of other nn-usenet Google stuff into it, then let it bitrot until it was effectively useless, and then removed the only search features that worked...

(Admittedly, if I recall correctly, Dejanews had already gone broke trying to maintain that archive before Google bought it, so arguably Google didn't kill it, they just bought the dying corpse and kept it animated in a zombie-like state for a decade or so past it's natural death...)

poem_for_your_sprog on Reddit produced this sublime poem:

http://www.reddit.com/r/books/comments/2ysvzb/terry_pratchet...

The sun goes down upon the Ankh,

And slowly, softly fades -

Across the Drum; the Royal Bank;

The River-Gate; the Shades.

A stony circle's closed to elves;

And here, where lines are blurred,

Between the stacks of books on shelves,

A quiet 'Ook' is heard.

A copper steps the city-street

On paths he's often passed;

The final march; the final beat;

The time to rest at last.

He gives his badge a final shine,

And sadly shakes his head -

While Granny lies beneath a sign

That says: 'I aten't dead.'

The Luggage shifts in sleep and dreams;

It's now. The time's at hand.

For where it's always night, it seems,

A timer clears of sand.

And so it is that Death arrives,

When all the time has gone...

But dreams endure, and hope survives,

And Discworld carries on.

I ran a comic book shop for a couple of years (this was 8 years ago), including a big deal of MtG (selling, organising tournaments, etc) [1]

From the point of view of the marketing, it is absolutely BRILLIANT. It was an amazing well oiled machine that was printing money, while developing an impressive game that has been around for 20 years and hasn't grown old.
They knew all the ins and outs of the game from the rules to the way to organise tournaments and how to create a community that is absolutely obsessed with it, playing everyday.
It's easy enough that I've seen 8 year old kids playing, and complex enough that a match can be determine by a very precise use of the rules.

I've never really been a hard core player, but after watching it from the point of view of a business, it's really impressive.

Interestingly, when they refer to the red ink coming off the parchment, it's is not an ink, but an illumination.

Inks were historically gall inks that used lampblack for the first few weeks, and the ink gall to dissolve/burn the parchment. That's why inks were black: they were char.

The colors though, were compounds painted on the manuscript to provide color. Malachite, lapis, lead, mercury, arsenic, and copper were all traditional pigments. So, when they say the red ink is flaking off, it's actually a red lead flaking.

And yes, these methods last hundreds of years. And many of them are as vibrant as when they were created.

On Google's “Build and Buy” Acquisition Strategy
This, in so many ways. If you want to espouse what the Founding Fathers envisioned, then put yourself in the shoes of someone who just led a fledgling populace to a bloody victory over an oppressive monarchy half-way across the world.

The Battles of Lexington and Concord were preceded by a secret British order to confiscate and destroy the military supplies (rifles, ammo, cannons) of the militia that had been formed following tensions between Patriots and the British after the Boston Tea Party. [0]

So the very first act of military aggression - and the "shot heard round the world" - was at least in part the last resort of the militia after a failed attempt to confiscate guns.

So when someone considers what the Founding Fathers actually envisioned, it is absolutely that the people of the United States always be able to stand up to a standing army. We can argue the current practicality of citizens owning nukes, but that doesn't remove the spirit of the amendment.

My mistake. I should have known that someone would take the opportunity to mince words when we're on the topic of language and communication, if it would suit their goal.

To be more concrete: I meant penetrate usage in writing in a contemporary setting. I don't know if it penetrated usage over a hundred years ago if it isn't relevant to written communication today. I communicate with people in this era, not with people from the past. Debating whether using a gendered pronoun obscures meaning or not implicitly refers to communication in this day and age, not the past.

Depression Makes Time Feel Slower
Having given a lot of complexity interviews, I value a candidate who says, "This is O(n^2) and it seems like there's a faster way, but I can't see it" over one who stumbles on the right solution.

If they had to tell you your solution was slow, and a linear solution exists it might not be your inability to find it that made you mess up the interview. Get good at recognizing inefficient computation first, then worry about making it more efficient. On the job you can always consult a coworker/google, but if you don't know to do that you're going to ship some slow code.
Hey there, Thomas from Watsi here. We actually used to have a "Donate monthly" checkout during the one-time donation flow, but in the several months that the checkbox was live, I think exactly one person ever checked it. We also have a link to the Universal Fund after you make a one-time donation, and that's seen good conversions.

That said, I definitely agree that there are other ways to solicit a donor to join the Universal Fund during / after a one-time donation. Our next idea for a test is to add a quick option immediately after a one-time donation that let's you sign up right there, something like, "Donate $5 every month! [Yes] / [No]".
> John and Logan realized that women feel much more comfortable getting into a car if there’s a woman. Today 30% of the Lyft drivers are women, which has also had the effect of attracting women passengers who now make up more than half of all riders.

And in the intervening years, no one running a news server thought to back theirs up, no one crawled Google and made torrents?

This is software, not ancient manuscripts written by scribes on now crumbling vellum - there is no excuse for there to be one canonical copy of anything. Every pornographic movie ever made has multiple redundant backups on decentralized peer to peer networks and darknets.

I understand the importance of maintaining references, but realistically, expecting URLS to be permanent is shortsighted at best, unless you own that domain and the server it's on and expect to have the money to keep the rights to it in perpetuity. You can't expect a third party host to be willing to keep the servers on forever.

But as far as the historical record and the data itself - Google's given warning, people can move their data or lose it. Fork and move on.

Ask HN: How do you deal with learning anxiety?
There is so much to learn, so many interesting things to explore - that is just in software. Then there are bajillion things to learn in other topics that are not tech. But we have so little time, especially as we grow older.

How do you guys decide what to learn and what to ignore? How do you decide not to get anxious, not to feel like a dumb person/loser all the time, because you didn't know some specific info on a specific topic? And once you decide what to learn, how do you go about sticking with it and keeping yourself up-to-date?
The problem with MD5 here is the relatively poor collision resistance, not the length extension.

Length extension allows you to calculate the final hash of appended data without knowing the original data. H(secret + data) is vulnerable because you can calculate H(secret + data + extra) without knowing secret. The solution here is to use an HMAC, and in this case MD5 is still sufficient. It doesn't apply to the post's context at all.

SHA256 is sufficient to verify a file hasn't changed. The next step up would be to sign the file with a PGP key, which allows you to verify the source as well.
Is it actually a good business model, though? My understanding is GitHub is not profitable, and relies on VC funding to keep operating. At this point it seems like it will never be profitable unless they find some other significant source of income (as there's no reason to believe that there's hordes of companies out there just waiting to start paying GitHub for private repos). What's going to happen when the VC funding dries up?
Will definitely love to work with some people but think others are just bad influence. Also, the way I see it, the company burnt bridges. I will be polite, but I don't want to do anything with them anymore, product or employment wise

In contrast to "au revoir", the French expression for a final parting is "adieu". This is a shortening of of "a Dieu vous comant" ("I commend you to God"). In a sense, this is the opposite of "goodbye", at least in the implied direction of divine intercession.
