Odd Thomas: Meet Stephen Sommers' CG Bodachs
> While there are also modes of operation (like OFB and CFB) that can produce self-synchronizing stream ciphers, these are far less common, and not discussed here.

Aw. :( Aren't there any noteworthy attacks against these modes?
Yeah and whoever is running that AI is being a complete a-hole with the rate they're sending commands.

It's completing the puzzle in less than 5 seconds at the rate that its spamming commands.
I'm always surprised when people accidentally admit they don't brush their toilet regularly.
Er... you think you're startup (microcosm), which is glorified forum software, will change "political systems, the structure of them and how populaces engage with them?"
Indeed. Black swans are (by definition) not predictable, so to claim that you can predict one is pretty weird.
Judging from my experience with the dev kit, even on my gaming rig there was a little bit of trouble running some of the games fast enough.

Your machine needs to be capable of running your game at 1080p 60fps. Not sure how the rMBP stacks up, but for most of the demos you should be able to play on low.

I found the best demos were more about an experience then games. The novelty wears off after a while, but I think when the real games come out, that's when things are going to get interesting.
As an ex-trader I always wonder what the right attack vector is, but I agree generally. BB is not standing still by any means.

The flipside is, most of the money managed by firms is not handled over Bloomberg nor is Bloomberg the final point of analysis before trades are made. For example one group at my old firm (in fixed income) used a custom built set of tools on top of excel connected directly to their own bare metal sitting on the floors of all the exchanges where they traded contracts. They pulled in their own prices at their own frequency (which was much faster/accurate than available via Bloomberg). Same was true in our group - data came from the exchanges (though with not as custom/frequent a setup), and bloomberg was used as a quick and dirty way to look up historicals/trends, rather than anything live.

More recently I've thought the best attack vector is messaging. There isn't a Bloomberg messaging app on the appstore. Of all the use cases, this is the most irreplaceable - you can probably pay up for all the data flows (banks all pay exchanges directly for higher fidelity data flows than Bloomberg provides) but aggregating that 500k odd userbase of finance professionals? INSANELY HARD. If Bloomberg had an API though . . .
"error-free Internet" is a fair description. Given suitable hardware and a connection, you can reliably send email, access Web servers, run Web services, regardless of distance. The errors, if they occur, tend not to be a the software level.
I suppose the grass is greener on the other side. As a Canadian I trust the US tech industry. Everything that has been exposed in the US has been happening here too, and then some. The options are: spend lots of money to be spied on here; spend much less money to be spied on in the US.
I keep wondering about the "my religious law doesn't allow for abortions" exception to things. As in, "Why does the Legislative Branch push that kind of thing?" Because when push comes to shove, and the USA institutes conscription for war, the Quakers, Mennonites and other "peace churches" will use that sort of exception as a wedge into conscription. If the Catholics and Baptists get to have some privileges about abortion, why shouldn't the Hutterites and the Amish get a pass on conscription? That will go down really well.

I don't fell that being happy is worth it. If I needed no money and no attention, perhaps happiness shouldn't also be the next goal to achieve. See what I mean here: https://www.youtube.com/watch?v=U88jj6PSD7w

So, they are opensource non-free. It will be interesting to see this model progress. If successful it could be a turning point for openness in software, but would pull requests be accepted into main? Would they get a cut of the cake? It would be interesting to see github handling this instead of patent and secrecy.
You can't build part of an engine in three months and then show it off on demo day.

You can't build a database in three months and show it off on Demo Day either, but we've funded many database companies.

You don't need to have shipped by Demo Day. You just need to have achieved enough to convince investors to give you more money. What "enough" means depends on what you're building. Experienced investors know how much they can reasonably expect from each type of company in 3 + n months.

Incidentally, we have battery and AI companies in the current batch.
Makes you wonder why aren't online classes kept, at least a year or something, in case the information is out of date (for technology)?
Finally! That "build something on Twitter" was irrelevant 3 years ago. Especially once Twitter implemented a system-wide ceiling which capped any new ideas user base to 100k users. I'm glad to see that you're focusing on products that aren't routed in social media. Bravo Sam.
Someday this will probably happen, and we will be as helpless to stop it as factory workers are right now. Denying this is just wishful thinking.

But no one's survival should hinge on a business model, this is a flaw of our economic and political system. You're conflating the two problems. If the 'music industry' has to survive in order to enable people to survive or art to propagate, this is the real problem.
>If you could convince enough drivers

Good luck with that. If you even tried to convince drivers to do that, they'd scream about a conspiracy to track everyone's movement (beyond the tracking that already exists).
Interesting, this is the thing though;

"I wouldn't want to have to give that up, or to have to arrange alternate transportation."

Lets say that lots of people had all electric cars, and they had the same restrictions as the current model S. How long do you think it would take before someone opens a business where you drive your electric car there, park it and plug it in, and drive the gas powered car that is already parked there to your destination, when you return you park the gas powered car, walk over and get into your own electric car and go home? Think Zipcar for the Tesla Set. Pre-arranged membership, fixed price rental on a daily or hourly basis. Different kinds of cars (small, medium, van maybe). You provide gas and damage insurance and a small annual 'retainer' fee.

That kind of business emerges when you have a large cohort of electric car users in a specific geography. I'd start one in the Bay Area if I was bored.
how in the hell this is not got to the first page ?
There are a lot of things in life which are better than money, and they're all very, very expensive
I totally agree. It is the main reason I like the post apocalyptic genre. It's fun to think about not having to go to a job for money, building a fort, and attempting to just live. :)
Power isn't really an indicator of how dangerous something is. You can kill someone on a watt. This is a solved problem, and the 120kW stations are already deployed throughout the country, without any reports of electrocutions.
As an active investor in the energy space, I would love to hear how Sam/YC see their model working here. The MVP and concept of early sales is something that is very difficult in this and many of the other markets they mentioned. We try with all of our companies to partner with larger organizations and generate early, profitable revenue. But it is difficult in many industries and there is still a large capital need.

That being said, would love to attend a YC non-software demo day.
Or, are you? There are no counts with the colors; it could well be that every color past the top 5/10 are used by a single person.

Are the World’s ATMs Ready For April XPiration?
You don't know what you are saying. I suppose you speak about RSA-4096, which is about prime numbers. The 256 bits are just used as a seed to find large prime numbers. The 256bit entropy is more than enough to be secure, and 4096 bit prime numbers are never as secure as 256 bit entropy.
It's a good debunking... but as a piss-poor private pilot, I think he, an advanced test pilot, might underestimate the ability of some pilots to stray pretty far from how they are trained, in a highly stressful situation, and possibly more so in less advanced countries or airlines where they are not highly incentivized to always do everything by the book... see the Korean crash at SFO... And even on AF 447 allegedly the co-pilot was pulling back on the stick in a stall... so was the Colgan Air pilot in the US -

Yeah, those chords certainly don't look quite right. There's some missed changes and some that show up a beat too early or too late. It's also missing a lot of subtleties, like 7th chords and inversions.

For a much more blatant example of Chordify just failing to spot really obvious things, check out their results for "Get Lucky":

http://chordify.net/chords/daft-punk-get-lucky-jay-lee

This song has a completely fixed chord scheme (Bm/D/F#m/E). Each exception in the chord sheet is a mistake.
They seem to push the idea of the ability to build charts without JavaScript. On the other hand, I have to learn their XML markup. Is the markup universal in anyway or is it proprietary to their charting library?
Is that a thing? I don't seem to be able to do that with 18k+, so if it exists there are only a couple dozen people that can.
Calculate set partitions with specific group sizes
Former ship's electrical officer here. We transfer 1000x that much energy to vehicles (ships) from stations (pierside "hotel" power) all the time.

Electrical transfer is far safer than transfering the same amount of energy in chemical form (e.g. gasoline) and letting any lunatic walk up to publicly accessible nozzles and point them whereever they want with or without a lit cigarette.

* charging leaves zero risk of explosive residue

* it's ridiculously easy to apply interlocks at every step of the transfer.

* the exact rate and requirement of energy transfer is very easily calculated and monitored and self-balancing. Ancillary variables like temperature and thermal expansion are equally cheap and easy to measure with very high precision.

* At scale, the marginal cost of solar power gets really close to free. I have plenty of neighbors who are getting rebate checks from the local utility instead of paying them.

* Energy density remains the biggest hurdle, but it's already provably good enough. The pricepoint is high only because of the small scale of production and the high-end stuff (leather seats, etc) wrapped around it.

"The Code Book", by Simon Singh, would be a good companion read. It covers much of the above, and is both compelling and well-written.

Edit: Fixed from "Code" to "The Code Book". Although "Code" (Charles Petzold), on a different subject, is also excellent.
Host it on something like GitHub?
I'm 99% sure this follows a power law distribution.
New convert here - thanks! Much better than my previous one.
The problem with #ffffff topcolor is active top nav links are invisible.
The public charging stations I've seen in the USA are standard mains, 240V tops. They are not superchargers. They will give you a little top-up but won't recharge your car while you're shopping.

The amount of energy stored, transported, and sold as liquid automobile fuel is amazing. Current electrical infrastructure is not even close to being prepared to replace it on a "disruptive" scale.
What is .. oh per-profile topcolor option. Never took the time to use that.
Having spent most of my working life in corporate world, when I first came across people working side projects my initial reaction was that they wouldn't be a good employee. My assumption was they are here for a pay check while their passion and energy goes into their personal projects. Also you felt you'd train them up and they would be off in 6 months.

But working with a few of these guys I found they are usually the best employees. They tend to bring energy and innovation to everything they do and generally better than a corporate drone who really does just want to cash paychecks for the rest of their life. At least in my area of marketing where one needs to look for innovation. Also they didn't exit after 6 months as building side businesses takes time and don't all succeed. For me know I'd take side projects as a plus on a CV but I suspect many people will hold to that first instinct I felt.
Intel processors now get OS locked
The acronym of the previous name of my company was SMEG, and so many of our business services are registered under that name. The 20-somethings here don't really understand why the staff 30+ find it hilarious when discussing smeg-related things... "The SMEG hosting bill hasn't been paid yet" and so forth.
There's a large community of musicians who supplement their income with Skype lessons these days. For $45 I can have an hour with some of the best musicians in world and folk music for example - heroes whose CDs I listened to as a teenager. Whether they're in Florida, Dublin, Germany or here in Seattle, location has stopped being a barrier. It's awesome.

But Skype and Google talk are both terrible for it; there's no easy place to show notes (of the wordy kind or the musical kind), a mock instrument would be great too, to show learners new chord shapes, for example. And the audio encoding on the video streams are optimized for speech, making music a bit warbley at times.

It'd be great to see tools like this adapted to music lessons, and I bet it's more sustainable business with more opportunities to create real value (store lesson plans for example).
I think this is extremely likely for you.

It may be partially due to my training as a researcher keeping my eyes open to it, but it is a pretty rare month that goes by where I don't run into an interesting problem I could easily spend a year or two working productively on. Many of them don't come out of my current work or even during my work time.

The idea of running out of "good ideas" is unfathomable to me, honestly. Running out of time is very easy to imagine, though.
what about (n(n+1)/2)< 1000 n^2 ? .
You're spending a lot of effort putting it down, when others are having a good time with it or even learning something by writing it (or inspired to write yet another variant).
To everybody considering Crashplan, you need to be careful with them too, during the two years I've used them they twice deleted the backup of a external hdd I don't mount too often, even though I had it set to never delete files. All I got from their support was excuses.

This was over a year ago, not sure if it's still the case, just be sure not to rely solely on them.
"With dozens of groups working on the problem and an eventual market worth probably $1 trillion I have no doubt there will be a solution within the next couple of years." - people have been saying effectively the same thing about fusion for 50 years, and it still hasn't happened. Just because something would be nice doesn't make it possible or likely it will happen soon.
Not so fast. Retailers' gross is SRP*Units. Dev's gross is what the next link in the supply chain pays him. That is still true in today's distribution model since Apple/Play/Steam store take some cut of the retail price and pays you the rest. One could even argue that you developing and you selling are two distinct companies and that gross is what dev you makes (actually they are quite distinct business functions, so I'm not bending anything here).
Metacomment: I like how you are copying PGs use of footnotes, but please copy his html as well and make them link back and forth.
By making games. There are lots of engines and frameworks these days to cater to people who want to create a game, but don't want to or can't do it from the ground up. Game Maker Studio and of course Unity come to mind.
I wonder if the gray people use (I use aaaaaa) says something about individual monitor choices. I'd probably go lighter if I used a windows machine more.
I was going to write this... but in mine, the whole board is the bird, and you play normal 2048 while avoiding barriers.
Cool, thanks. I have already played around a bit with adding some hover effects etc, which is indeed straightforward since I can just use a plain old selector as you mention, etc.

I need to mess around to see if there is a straightforward way I could get a reference to the underlying data item (the row in the .csv for many of your examples, etc) from the context of a callback that fires on say $('bar').hover() or what have you. Will look into it.

Anyway thanks for answering, and nice work.
Take an interest in anthropology and observe how communities interact and shape the environment (and systems of hierarchy and control) around them, and then consider how software can influence interactions.

Not that I'd argue with you with where we're at today. The destination may be over the horizon, but the first milestone is right in front of us and looks like we've barely moved. Which is true.
Healthcare costs grow faster than inflation, which is unsustainable.
I like #123456 and #abcdef as colours; #123456 doesn't work here (black on #123456 is difficult to read) but #abcdef works well.
An interesting addendum to Rumsfeld's categorization of knowledge is Slavoj Zizek's notion of the unknown known:

What he forgot to add was the crucial fourth term: the "unknown knowns," the things we don't know that we know-which is precisely, the Freudian unconscious, the "knowledge which doesn't know itself," as Lacan used to say.

If Rumsfeld thinks that the main dangers in the confrontation with Iraq were the "unknown unknowns," that is, the threats from Saddam whose nature we cannot even suspect, then the Abu Ghraib scandal shows that the main dangers lie in the "unknown knowns" - the disavowed beliefs, suppositions and obscene practices we pretend not to know about, even though they form the background of our public values."

http://www.lacan.com/zizekrumsfeld.htm

I agree with Zizek's assessment that unknown knowns are even more dangerous than unknown unknowns.
I can't claim to understand much of the statistics, but according to [1], p-values are pretty sketchy as a measure of "is this likely to be true?"

I do :)

But honestly I like to see any knowledge in low level systems - especially operating systems. I think it's important for people to know what their code is running on!
For what kind of game? For something like a FPS this requires significant coordination.
Yep: My color #a4157a disappears from the list when I changed it. It's a 1337-ified "Arista", the name of the company I work for which I happen to think looks nice.

It appears about 1/4 of the way down the list, so I assume most of said list is unique entries then.

Who's making such a claim about VR? People who think Michael Abrash made this claim simply didn't read his white paper closely enough. Here's what he said:

Another huge thing -- Data quality. Bloomberg gets free crowd-sourced feedback on their data. Apparently, there are hedge-funds (especially for less liquid assets) that make money by finding broken data, buying something cheap (or shorting) and then calling BBG to fix their info.
yeah the effect of a fueling accident with EV's at the voltage and amperage used in those charging stations is going to be serious.
Are you making the most of LinkedIn to grow your business?
Are there serious descriptions of these good-old-days software methodologies that the kids these days with their agile and their hippety-hop are corrupting? The story I've always been told is that 'Waterfall' is a pejorative invented by software methodology pitchmen to describe the ad-hoc process you get when you ask an MBA to build a software shop.

As someone who's had a little bit of exposure to 20th century code, I'm not terribly impressed with it. It's neat that they managed to get anything at all done on such primitive hardware, but incredible feats of performance hackery isn't the same thing as software quality as we know it.

Someone explain to me the lost methodology of these programmer-Titans who made this "truly excellent, reliable code"?

p.s. Since when was the Internet a software product?
Ask HN: Who wants to help build an open source cryptocoin exchange?
The number one problem with all cryptocurrencies is the lack of security and lack of due-care by the developers. I've started a repository and would love if anyone interested in helping save the credibility of Bitcoin, Litecoin and any other cryptocoin would help build something worthy of the community.

The repository is on Github here: https://github.com/Vheissu/Wolfcoin — no language or framework has been decided upon just yet. It will be truly open source right from the get-go. I was thinking Node.js could be a nice fit, but ultimately the community can decide.
Yup. And, it can't be "idea to demo day" in 3 months for those hardware issues where iterations take weeks (or at least days) compared to hours/minutes for compile-time on software.

I love the change in focus to be more bold, real, rather than just chasing easy things like software/apps/games. But, the model must change too. I think Sam & team are up for that challenge, & will adapt, so don't think of this as a permanent shortcoming in any way.
There is zero cryptography value in spending more than 5 minutes on a Caesar cipher or ROT13. It's a shame that so many university courses on cryptography even waste such time on such topics. It would be like teaching times-tables in a course on calculus.
Crytek announces its CryEngine-as-a-Service Program
Come to think of it, you could wrap it around a thin wrapper program and provide that as a product for a nominal fee over which you'd have to pay 5%, then develop your game over the wrapper.
What is to stop anyone from doing this? Maybe the license says your product must be licensed the same way, so if the end user mods your game and sells it they too have to pay 5%.
You've totally missed the point. Yes toasters can kill people, but statistically very few deaths are by toaster. That's why as a society we've decided the useful convenience of toasters outweighs their inherent dangers. Similarly, we've decided that really cheap meters are beneficial enough to outweigh the slight possibility that someone might measure a too-high voltage while using the meter as an eyeshield or baby toy or something.
