I've never had that - 9-5 from my experience meant working 7 hours with a 1 hour lunch. Of course YMMV, but I don't take any employer seriously when they say otherwise - if they want to raise hell, I'd probably just walk.
I've hit this a few times in Python and it bugged me like crazy. But then I grew up and dealt with it.

I feel like this is the startup that so many of us have always wanted to do. Kudos for doing it!
That example in figure 1 really confused me for a moment, since it's a mix of GAS and Intel syntax - no $ or %, but with size suffices and the opposite operand order.

It's interesting to observe that "brute force" approaches to optimisation are yielding very good results, but I've always believed (and in this case, the "in some cases, expert handwritten assembly" phrase somewhat seems to support this) that making compilers more intelligent is the way to go -- make them "think" more like a human Asm programmer would.

For example, using their first sequence, 3 out of 11 instructions are moves that do nothing more than unproductive "register shuffling", which suggests to me that there's still room for improvement. As the saying goes, "the fastest way to do something is to not do it at all." That shuffling is only there because they constrained their register usage, and if I was implementing this, I'd arrange the code that came before such that the right operands are naturally in the right registers when instructions that require them e.g. mul are used. To my knowledge, this technique is not implemented in any compiler and none of the existing research on register allocation or optimisation mentions anything like that; instead they all seem to suggest "introduce extra moves and hope we can somehow remove them"... which doesn't work as well as planning ahead so you don't ever need them in the first place. Moves should only be used for making copies of values, since instructions that do other operations can implicitly "move" data as part of their operation anyway. Applying this principle to their first example eliminates two moves and yields this sequence:

shlq 32, rcx
movl edx, eax <-- move + zero-extend
xorq rcx, rax <-- why xor? or probably works too
mulq rsi
addq r8, rdi
adcq 0, rdx
addq rax, rdi <-- we want result in rdi anyway
adcq 0, rdx
movq rdx, r8 <-- this is still "room for improvement"

I think the same goes for optimisation as a separate pass - the idea of generating horribly inefficient code (gcc -O0 is a great example) and then trying to optimise it just doesn't make much sense to me; in my mind, if I tell a compiler to do max size or speed optimisation, it should be selecting and generating instructions that are pretty close to optimal already. I wonder if this is a result of that famous "premature optimisation" quote...

"Fastest" is also something that can be highly dependent on the processor model, so this is also important to keep in mind if you're compiling on one machine but executing on another. If anyone would like to, I'd be really interested in seeing the performance of my two-moves-less sequence above vs the one in the paper (don't have a 64-bit machine to test this on at the moment.)

> For the most part, no one cares whether they're using something that is open source or proprietary. Most people don't event care much about abstract concepts like "security" or "encryption"

You say it as if it's universal and intractable. Awareness has jumped since Snowden's revelations began, AFAICT, and I've read several places that security-oriented services have seen a very large jump in demand.
"Old technology and keeping disconnected from the Internet are probably decent additional security measures, although they shouldn't rely on it. "

It's called an airgap, and is easily the most effective countermeasure to cyber attacks, and, in conjunction with physical security and careful 2-man control/people management, should certainly be relied on.
But something you really really want ... even 30 minutes after launch. You do not want a bang when you were expecting silence, nor silence when you were expecting a bang.
I suspect this is what they have in mind long term, for starters i'm guessing they are just going to filter both jobs and developers to a realistic starting point.

For example, trashbin and "i want an ebay clone" elance style requests, and filter out the developers who claim to be able to do it for $500 in 12 days.

That alone would cut down most of the crap you see on sites like elance.

As for their fears (dsrguru posted) about people going out of band to work around 4% for a measly $140 I don't see how that would really come into it as a reason for doing the filtering. $140 is nothing to a developer for a guaranteed payment on completion, its also against the interests of the buyer as they may end up with subpar quality and an angry developer chasing them down for work they didn't really do to a reliable standard.

Sure, there will likely be a few who try to work around it, but really they aren't the target market user to begin with (the i want ebay for 500$!!? types)

I have Cystic Fibrosis. I don't think it's fair to assume that the bell curve associated with treatment results is fair to attribute to the quality of care. Factors such as climate and pollution can significantly contribute to health, as can socio-economic and average distance patients travel, as well as access to insurance.

For instance, I'm from North Texas; I went to college in Oklahoma. Back then (1996) Texas had a type of insurance for children with CF (it actually extended to age 21) unavailable in Oklahoma. I ended up losing care, going off of my meds, and by the time I was back in Texas and had the income to support my needs (I came from a very poor family) I had lost 30 pounds (down to 98lbs) and had lost 25% of my lung capacity. Was this attributable to the clinic in Dallas? Of course not.

(FWIW, I'm up to 155lbs these days and my lung capacity is probably in the upper 5-10% of all CF patients)
Since you're asking for advice, don't go into business "with your friends" who have "no experience." You'll lose one without gaining any of the other.
On the bright side, this project acknowledges the killer issue with these kinds of marketplaces: scalably managing quality, scope, and disputes.

But on the other hand, I see nothing but assurances and a woefully low cut that I can't imagine could keep this train chugging without shoveling time (=money) into the furnace. At ~$140 revenue a pop, if even 4% of projects go off the rails, the "insurance" policy already puts the company in the red -- forget profit.

There is a huge problem to solve here, for sure. I want someone to solve it. But I'm not seeing a solution.

I have 2 questions:

1. Why would anyone at S/C consider what he's doing slimy? He's not exploiting anybody, he's just shorting the stock and making the exploit known. If you think shorting stocks is slimy that's one thing, but would you rather have him short the stock and then NOT tell anyone about it? It seems like the only IMAGINABLE slimy thing is that he then tells people, making the short more valuable, but fuck is he supposed to NOT tell people? That would be SUPER wrong!

2. Why isn't this on the front page? It has enough upvotes in enough time, has it been flagged? Is "Weev" a flagged word?

> Another thing I'd like to see Betatype providing is some sort of franchised coaching and guidance to both the product owner and the developer on how to best set themselves and the other party up for success.

Coaching and guidance isn't a substitute for experience. You can learn about the product lifecycle by reading a book or taking a class, but that doesn't mean you know how to manage it in the real world. Frankly, the number of good developers who can also credibly wear the hat of product manager is much, much smaller than the number of good developers.

In semi-stealth mode, but currently working on a new floating point focused architecture that is rethinking a lot of concepts in order to focus on energy efficiency in the high performance computing space. The biggest problem historically has been software development related, as even if you have a kickass new architecture, if you can't write software for it, it is worthless. Thankfully we think we have a pretty good solution to this.
The Herbalife graphs seem to indicate that in the countries they enter there definitely is an initial temporary pop but business doesn't go down all the way to zero after that - it seems to settle down at a residual steady state. That could be sustainable if the 2 graphs provided (Israel, Japan) are representative of all the countries they enter. After they enter all available markets, their revenue will settle down to the sum total of all those steady states.

Congratulations, you just invented MS-DOS!
I am interested in parallel computation and computer architectures and thought it would be fun to experiment with. I have worked on some projects developing signal processing algorithms for large GPU arrays and I want to see how the Parallela compares. I plan on implementing a real time audio watermarking algorithm and some image/video processing algorithms.

I can't imagine not wanting to work on this. It must be really complicated at Google -- I'd take a 50-75% pay cut to work on this project at Google, rather than ads optimization. It must be an interesting organizational challenge figuring out how people get assigned to it; sort of like PARC vs. optimizing photocopier software at Xerox back in the day, except back then they kept PARC pretty much secret from engineering (from what I've read).

What? Do you mean "If you do get it, it will probably be quite obvious to those around you"? Given the rest of your sentence, I believe not. You should count yourself out on counseling.

I think it makes sense. It implicitly keeps the project scope very limited and it eliminates a lot of the haggling.

My biggest concern, like others have mentioned, is that it seems unscalable with the cut that the company keeps.
Phew. If they "upgraded" these things so they would work "in the cloud" or whatever then I'd be concerned. I certainly don't want to see a story about how generals can now launch the missiles from an iPhone app.
> No way

Sure there is, limit to what time they spend working on getting projects ready, if they don't meet a certain standard, drop them and give quick 5 second tips to get them back in the queue. If they don't produce a reasonable spec in enough attempts just drop them as a user.

Even the AP had a work around for scaling this further, run at a loss for some time while you identify patterns of failure, produce resources for the user to solve their own problems.

For $140 I could easily spend 10-20 minutes looking at a rough spec and tell you if it is workable for 3500, I'd even be able to put in a few slash points on which features would likely need to be cut.

For some perspective, $3500 @ $50/hour = 70 hours. In other words, 1-3 weeks of dev time.
> Comcast, et al. didn't want to upgrade their Cogent links to handle the required traffic from Netflix. Everyone sending Comcast traffic through Cogent was equally penalized during prime time hours. You can argue it's poor network management, but it is still "neutral".

That is my understanding. My comment was just pointing out that "net neutrality" is not considered a vague term by a considerable number of people.

I do think it is unfortunate that Netflix is incentivized to make this type of deal rather then their ISP.
Let this be a warning to all those who suspect. WE WILL GET YOU, EVEN IF IT TAKES 17 YEARS.
But you are filtering the LIDAR data (source: I have I Velodyne LIDAR in my office). Yes, one stray hit will be ignored. But, you aren't getting one stray hit. You get 20 hits on this revolution, 6 on the next, 21 on the next, and so on, and then use various algorithms to determine if you are seeing objects or noise. Recall that besides the inaccuracy of the spinning lidar (it does not hit exactly the same spot even when sitting still and hitting an immobile object), the car is moving. Any decent Bayesian filter derives a heck of a lot of information from these changes. I'm not talking about the physical change, which is also important (change of position = change in angle = different reflection point). I'm talking about how your process model generates information via hidden variables - from position over time we derive velocity, and the correlation between velocity and position increases our accuracy. In the context of the LIDAR, the filter can detect that there is a small clump of points moving towards the car at 70 mph (from it's point of view, of course from our POV it is the car approaching the debris at 70 mph). Reflections that are true noise will not be clumped, and will not consistently have a velocity that matches the car's.

With all that said, I've just played with the LIDAR, I can't give you lower detection limits. But with proper algorithms it is better than the static computation suggests.
I wonder how that deals with potholes or roads that lack the proper markings or one way streets.

Chicago has both of those.

Interview with an equity research associate

Reading a lot of comments here, the theme seems to be that the benefits will trickle down to the average consumer. I can see immediate cases where it's just going to go to those with sufficient economic muscle.

Less need for a garage means smaller houses, and more of them (for example).

Improved insurance? Probably the same insurance premiums (inflation adjusted), with a higher premium for more human miles driven.

If there is money on the table, it will get taken by those with the wherewithal to grab it.
> she told the similarly drunk guy she was cold - a standard hookup line to initiate hugging, which is all that happened

"I woke up with my pants undone and down (but not completely removed). My top and bra around my neck, and to my horror, Matt behind me. Holding me."

Sure doesn't sound like just hugging. Also her post doesn't say she simply told the guy she was cold, it says she directly asked him to turn on the heater. Either way, what's said to have happened next would be a very clear indication that she didn't mean anything romantic of it:

Typo under 'Both sides get what they really want'.

> Programmers get get paid to implement a well-defined spec.
I look at it like this: There are 4 directions that a software project can be constrained: Time, price, scope, and quality.

1. Elance or ODesk can offer you fixed time, price, and scope, but highly erratic quality.

2. An expensive contracting agency can offer you fixed time, scope, and quality, but with high costs.

3. This site promises fixed cost, and quality, but makes no promises on scope or completion timeline.

All that's left is for someone to make a site that has fixed timing, like "Software Prototypes in One Week". I'll wait for that one to hit the front page of HN. As a developer I'd actually prefer that because I know when it's going to be over.

2 suggestions:

1) rails + Heroku. Rails for the community and plethora of pre-built wheels, and Heroku for the absolute brain dead deployment of your creations. (you'll need to learn like 4 git commands)

2) I'll prototype your ideas in any language you want if you give me access to your network. Deal?
It sounds like each test involved the same person both giving injections and sitting in the room. I wonder if they can somehow mechanically inject the irritant without human involvement. Then they could have male/female participants sit in the room without knowing if any animals are present. This would help distinguish whether the rodents were reacting to a general difference in scents, or males and females give off different signals when handling rodents.

I have a feeling their numbers are soft for a reason. 5000 is a solid investment, 3500, thats a small portion of dayjobs income i could drop to get a sideproject trialed. 4% is also very minor, where 5+ would likely look a little too middleman-y for my liking.

Limit the size of the project, limit the size of the investment, limit the cost.

Going forward I expect they will have to do some form of tiering once they see the type of work is in demand, and which type of work is achievable by their developers (which all is still unknown at this point) Example tiers: 500-1000 = quick site, 3500 = mvp, 5000-10000 = soft launch
>it's an odd balance between tech that's obsolete enough to be secure, but still current enough to, you know, actually work.

What? We stopped using Floppies for more than just storage space guys, they had fundamental longevity problems. A simple CD upgrade of flash drive that's write-locked after created would go a long ways.

What about the readers themselves? Do they have some company special making 8" Floppy readers and are swapping them every so many years to ensure they will actually read the floppy correctly when it's go-time?

Simply using really old tech doesn't make it more secure...
in society at large after 1980 or so

You are, as I recall, too young to know about times before 1980 by personal experience. I'm not sure what you are referring to here, but if you are referring to deinstitutionalization, that happened MUCH earlier, with considerable impetus from the personal experience of President Kennedy.

In the old days of Freudianism, stigma was worse and the affliction of people with mental illness was worse. (Basis of knowledge: much specific reading on these topics, including reading about the history of diagnosis and treatment of major mental disorders, and having lived through all the years mentioned in this reply.)
Of course. Filters do wonders - but they're still not a panacea.

You also get the covariance across that filter. Which means you still need to decide how much to cut, whether or not to reject as rain, dust or a reflection, whether to trust your reflections under a certain reflectivity value. Data helps with this, but, as always, there's a ton of corner cases.
To all the people saying this price is so too low- don't you think that they are doing this to attract a bunch of people to solve the chicken-egg network effect problem first? Then I'm sure they will raise their cut.
The patently evasive language of Horvath's non-denial -- contrasted with the very specific language in the (albeit anonymous, but credible-sounding) medium post -- make it increasingly difficult to take anything else she's saying seriously, moving forward.

In particular -- if she's going to level tacit, but just the same highly public and career-damaging accusations of sexual harassment or other misconduct against other GitHub employees -- which, going by the language of her recent j'accuse tweet ("Don't do business with ...") would pretty much have to be what she's implying (even though she won't say it directly)[1,2] -- then she had better be prepared to back up what she's saying with reality-based specifics.

Being as, going by her "uneven", to say the least, track record on veracity thus far, we just don't have much reason to give her the benefit of the doubt.

But range is always difficult. I think PMD is in use in BMWs. They purport a 90 meter(!) range, but I've never played with one.
Also worth noting: in 2009, the Texas Forensic Science Commission was looking into the Willingham case. Two days before the commission was scheduled to hear evidence that could have exonerated Willingham, Gov. Rick Perry ousted the chairman and two members. The hearing was canceled, and the inquiry was effectively shut down. [1]

The final report, released a year and a half later, only recommended more training for fire investigators; it did not examine exculpatory evidence, or issue any finding regarding negligence or professional misconduct. [2] Two months after that, Texas AG Greg Abbott issued a ruling prohibiting the commission from investigating evidence from prior to 2005, ensuring that the commission will not examine exculpatory evidence in the future.

Do you currently own a home?
Right, I agree with what you've said completely. The reason I introduced the concept of "coaching and guidance" here is because I believe it would be required on both sides for eligible parties at the $3,500 price point. I really wouldn't expect "good developers who can also credibly wear the hat of a product manager" to be picking up $3,500 contracts on a site like this, however, I could see it being a stepping stone for mid-level developers who are entry-level consultants.
