Without knowing why jill left, you can't really answer the question.

I think the article assumes Jill did something that caused her to want to leave (she found a new job, networked and someone offered, etc...) but maybe it was the employer? The employer could have challenged her on time off compensation, insurance coverage, etc...
time (sadly) isn't comparable to Joda Time.

Thank goodness for the youth. For, while nothing is new under the sun, they don't know that yet.
My issue with this solution and sshuttle was performance is good for web browsing and other basic tasks, but good luck with more complicated higher-bandwidth stuff.

That being said I did not use it more than a few days and maybe people have better anecdotes than me. I personally would stick with a properly configuring OpenVPN, or FreeSWAN if the whole HTTP/SSL tunneling VPN systems aren't your bag.
I see your point. I agree.
Gearboxes in the Engines... I cannot quite figure out how that works since they are not driving an axle or anything... are they?

Any aerospace engineers in the house?

On plus side, if they work, more power to them. On the downside, sounds like a maintenance / reliability nightmare in the making.

I would be very suprised if Amazon didn't have a very sophisticated address normalisation process (in Australia, there are several pieces of software that can process generic user provided addresses, and return a specific delivery ID ["DPID"] that ties to an explicit delivery location).
I was hoping for something with some metrics as to changes that would make bing better. This is nothing but one persons feelings on some simple changes that I personally don't think would make a difference.

I haven't been able to put my finger on it, but when using Bing (and yes I try on occasion), I find the results to be just as good as Google, but for some reason, I don't seem to click as much on Bing links. Bing just feels a bit colder and less welcoming, yet at the same time, it is so similar to Google that I can't figure out why that might be.
Speaking as a Canadian, I personally would rather funnel money into projects that keep Canadians employed. There is a rather difficult problem with competing against other larger nations in the west (especially our friendly neighbour) who too have large tax subsidies and grants.

Canada exports most of its oil refinery to the United States so it can double dip on taxes. It as a result employs Americans in the refineries. Should we stop subsidizing American jobs then?

It does seem weird that they store the uncompressed image on the disk. I think that a benchmark on this comparing with compressed / decompress on CPU would be interesting because one is bounded on I/O, another is bounded by CPU throughput.

It's on github (https://github.com/mashape/unirest-obj-c), so I expect someone will submit a podspec in the next 24 hours. One of the awesome things about CocoaPods is you can also write a podspec for a repo you don't control. So even if the creators refuse to add CocoaPods support, you can still use CocoaPods to import it to your project.

edit: went ahead and added a pull request for a .podspec. Only a little bit of extra work, since I was writing one to test it out locally anyway.
Why are we passing this opportunity up?!?!?!

Oh Jesus Christ, common now we're a community of entrepreneurs & hackers, someone just create a new startup that's wikipedia for people.

PeoplePedia.com is taken but here, but I've got http://www.infopag.es so it's perfect for something like InfoPag.es/ChrisNorstrom.

If someone wants to join in reply to this comment. So basically I'm envisioning a wiki for people. However, there's 2 routes I can go down:

a) Anyone can create a page on a person and anyone can edit and add onto or delete content from that page. (lots of growth, but lots of potential for abuse)

b) People must register to create a page on themselves, anyone can edit that page and add onto or delete content but the registered owner must approve the edits.

Which sounds better?

Real analysis lectures of Francis Su at Harvey Mudd:

http://www.youtube.com/playlist?list=PL0E754696F72137EC

These could go with the either the book by W. Rudin or (haven't read) A. Browder. These are not easy for a complete beginner; maybe the lectures can provide some motivation. "Understanding Analysis" by S. Abbott is another rigorous and much easier, but very good, introduction.

"Advanced calculus" by Shlomo Sternberg ... a work of profound beauty. This was the book used at Harvard in the 60s for the best freshman students, but it begins in a slow yet deep way with sets, logic, linear algebra, calculus, metric spaces... It's my favourite book on calculus on manifolds. http://www.math.harvard.edu/~shlomo/

Some freely available books by Robert Ash: http://www.math.uiuc.edu/~r-ash/ - in particular, his misleadingly-named "Complex variables" (with W.P. Novinger) is a short, rigorous book on complex analysis.

"Naive Set Theory" by Paul Halmos is now available for something like $12.

(I have not read the following books.)

For number theory, maybe the book by George Andrews? It's very elementary and very cheap, and looks top notch.

I'd like to read "The Cauchy-Schwartz master class" (on inequalities) but haven't purchased it yet.

There are many books on combinatorics and graphs by the Hungarian school. Probably deserving special attention for discrete math are "Concrete mathematics" by Knuth et al. and "Analysis of algorithms" by Sedgewick and Flajolet (distinct from Sedgewick's "Algorithms").

Startup Weekend - My Experience
As of Mac OS X 10.6 (xnu 1456.1.26), Darwin has native user tunnels. utun devices are sockets rather than character devices and are created through a special control socket.

They behave the same as the Free/OpenBSD tunnels, in that they prepend the IP version as a 32-bit word.

See:

http://www.opensource.apple.com/source/xnu/xnu-2050.18.24/bs...

The point is the government doesn't know where to best spend the money. Quite why it has so much to spend is the other question, especially in Quebec where there are other rather pressing needs.

I don't think many Canadians realise just how many non-Canadian workers they are subsidising as a result of all of this. There is the official logic of training locals in skills that get imported alongside government incentives, however, what seems to happen is you get a mobile group of people that just follow the incentives around from province to province.

One thing Bombardier do have in their favour is they are a local entity and the taxes on any profits do return to the system, so I can't fault them on that.
Battle of the Year
I hadn't seen that. What a horrible response from Rhinehart. His whole tone is of "I know better than you, and am more rational than you"... It made me wonder if he didn't know who Tim Ferriss was nor what experience he's had.

I'm neither For/Against Soylent, but after reading that I have a fairly negative view on Rhinehart.

As an extra: His response to 1-size-fits-all is laughable, is he forgetting about the 1000s of eating issues people have (gluten, lactose, allergies, diabetes)... Sorry ranting now.
We only see the latest revision. There is no queue and thus not really any concept of a date.
Lavabit was not a VPN service.

It was a (poorly implemented) "secure email" service.
I agree that IPSEC should be the fastest & best, because it avoids the tun/tap device and works at the packet level. Anything that uses tun/tap and/or a TCP transport is not going to be as good; it needs tricks like sshuttle's very interesting ones. So I would guess that, of OpenVPN, sshuttle and OpenSSH, that OpenSSH/my script would be the worst because it uses tun/tap, TCP and has few if any tricks. But it is also the only one that "works for me", and I am very comfortable running SSH on my machines, and also with SSH security, and I find the key-trust model very simple to work with.

As to more demanding uses, I haven't tried e.g. accessing a video site like the BBC iPlayer, though maybe I should do so "in the name of science".
The relationship between employer and employee is not one between equals. The latter depends on the former for their livelihood, whereas the former could outsource or automate the latter's position without any affect on themselves at all.

So my answer to this would be - to a person, as much as they deserve. But to a company, as little as necessary.
I doubt it, precisely because of the volume.

The UK had a similar thing run by the BBC called Ceefax

I think the thing the author is missing is that there has never been one big culture. For a long time, the culture was segmented primarily by location: people in a region played the same sports and games, talked similarly, made the same music, and so on. Now, the culture is starting to split based on interests rather than geography.

It may be problematic that culture is now being sliced on this new axis, but don't just compare it to some imaginary wonderful past that never actually existed.
There's a difference in the claims.

Soylent as a simple meal replacement makes quite a bit of sense. It's the same as Weight Watcher shakes and the like-something you can eat to replace a meal once a day at most. That product can get away with not being perfectly nutritionally balanced because it's not meant to be eaten every meal. You can use the other meals to fill the nutritional holes left by it, even if you're using it to replace one meal a day.

Soylent as a total food replacement brings a LOT more scrutiny. It means that they have to prove that it IS perfectly nutritionally balanced, and that there aren't any adverse side effects for long-term consumption. That's where the snake oil responses come in, because the burden of proof is so much higher.
Thank you so much for that (genuinely!). This is the reason I love HN: in this discussion we have someone that pointed out the probably-good-enough-for-the-99% SOCKS proxy (let them eat SOCKS!), and you've now pointed me to the "right" tun/tap device for Mac OS X, saving me from hours of fixing something that is obsolete.

Now I really need to get a Mac and get this working there!

> Can I use bitcoin? Sort of. We currently support manual payouts using Coinbase. However, you cannot use bitcoin to pay in.
Absolutely agreed. For most companies, a couple instances of MySQL (or PostgreSQL/Oracle/SQLServer) with replication and backup should provide 4 nines uptime (which is probably comparable with what Google/Amazon offers in terms of availability). Throw in a few memcache here and there and you can easily scale up to millions of requests a day. FWIW, even Facebook is running on mysql/memcache.
CoreOS and ZeroVM are so young that there's not really much literature about them yet. That said, VMs and containers have been around for decades.

Lots of the recent activity is more about packaging and usability improvements, rather than theoretical improvements.

A quick overview:
CoreOS is a super-minimal Linux distribution designed to be used as a base for applications. It's essentially equivalent to the JEOS buzzword from five years ago. It would run inside of Xen or KVM or VMWare.

Xen, KVM, VMWare, Virtualbox, you probably already know about- they provide a virtual machine, the operating system running inside of it (theoretically) can't tell it's not on its own hardware. Xen uses a 'hypervisor', which is essentially a very tiny, custom kernel. KVM uses the Linux kernel as the hypervisor, which makes a lot of sense- you don't have to reimplement all the years of hardware support and scheduling work they've done. VMWare and Virtualbox run as applications on whatever OS you provide. You lose out on some opportunities for clever performance hacks this way, but there are other advantages. VMWare ESX[i] is more like Xen & KVM, but I don't really know that much about it.

Containers (BSD jails, Solaris zones, LXC, and of course, HN's lovechild Docker) let you provide VM-like isolation and resource management between processes or groups of processes, but you only run one kernel. This means much less duplicated effort and memory, and Docker's AUFS lets you deduplicate your storage too. There are slightly more security concerns about this approach than full VMs, the Linux kernel (and others, but let's be honest about the target audience) has a long and ugly history of local privilege escalations.

ZeroVM is based on Google Chrome's NaCL, and that's about all I know about it. I would expect VM-like security (it validates machine code), and an environment that requires serious porting from POSIX. That said, if you use Python, Ruby, Mono-compatible .NET, or Go, the heavy lifting has already been done for you.
One thing that is often overlooked when considering file I/O is that the kernel caches previously accessed files for fast reads. This, combined with the lazy-loading mmap() can prove for good performance with simultaneous low memory usage for something like an image cache.

This technique is used on the iOS home screen - both the icon images and the rendered icon labels are stored as uncompressed bitmaps on disk and mmap'd when needed into memory. The fast loading allows SpringBoard to aggressively recycle icon views.
Sorry, the entire point of using a VPN for privacy. If you're using it to connect to your office NAS, this discussion hardly matters.
How is does this solution compare to Google App Engine?
Sure, but are they marketed to nerds? That I can think of, products like this tend to be marketed towards health enthusiasts, gym goers, body builders, hikers etc. Techies may be any or all of those things, but those products don't categorically stroke the egos of "techies" by playing into their preconceived image of themselves. I've got some protein shake mix (not quite the same thing, but close enough) above my sink, but nobody on HN cares about that stuff; it's not marketed like Soylent is.

The last time I discussed Soylent on this site, I compared the marketing phenomenon around it to the "School Teacher discovers [whatever], Doctors hate her!" ads. I think everyone is fawning over soylent because they are techies, Rhinehart is a techie, and a techie somehow 'disrupting' a non-tech field fits their mental image of superiority. If Rhinehart were a nutritionist and if he were marketing this to, say, people into cardio, then this product wouldn't be notable.

(Note that this isn't me saying the product will sell poorly. It is just my reason for not, say, thinking that this is going to "Change Everything"(tm))
That's the one I was thinking of; thanks for finding.
As the creator of unirest-java, I will be happy if you want to contribute to the project.
RVM is already doing too much, and trying to do more. Sure there is no looking-back since I switched to rbenv a year ago.

> But keep in mind that the entire point of using a VPN is plausible deniability

People usually reach for a VPN when they do not trust the link they are using. e.g. it's coffee shop wireless. A VPN obscures the traffic travelling over the dangerous link and delivers it to the endpoint where it is usually on-routed.

On the whole, VPN's do NOT provide anonymity, they provide privacy. VPN connections always need a fixed endpoint which likely has some sort of billing relationship with you.

Services such as i2p and Tor provide anonymity.
I think it's extraordinarily unlikely that a boycott of Apple would do anything to cause Samsung to improve their behavior in any way. Most likely they would conclude that their general PR campaign to tarnish Apple was successful and be encouraged to turn it up further.

The wikipedia article explains the deets, but basically yes, the turbine at the back of the engine is connected to the fan at the front of the engine, and the compressor and whatnot, and the gearbox somewhat decouples the speed of the former and the latter. It would be a bit of a shame if said gearbox fails in flight, of course.
Wondering if there is any support for PVR compressed images(2bit/4bit)?
This looks pretty cool.

On the downside it can't do aggregates, it can't do query filters on more than one property, it can't do joins, it has its own unique query language, and it is a proprietary system with no chance of moving to another provider or hosting it yourself.

Speaking of it having its own query language, perhaps that isn't a big deal given you can't do any non-trivial queries.

For me, the pejorative NoSQL claim is actually a marketing turn off.
Shouldn't there always be a manual flying mechanism failsafe in the case of electrical failure? Fly-By-Wire doesn't seem very safe to me... in the same way I have doubts about Drive-By-Wire.
Interesting. They do need to advertise this better because I had no idea this service existed.
I currently require over 5000 calories a day and I am doing 4/7 days entirely with Soylent. It is really hard. However, I am surprised I can even do it some days and think about how much harder it would be if I picked some other nutritionally complete dish that tastes better.
You're right; my mistake. Sorry.

Does mmapping the file mean that it'll block on file I/O if it's not already cached, though? I don't see any claims (haven't read the code) that it prevents this.
You give it an x86 (or ARM) binary to execute. NaCL is also working on an LLVM version, that would get compiled to the specific machine at runtime.

IPC is super limited: https://github.com/zerovm/zerovm/blob/master/doc/api.txt

You get nothing but /dev/stdin, /dev/stdout, and /dev/stderr by default. You can optionally make other resources (network, files) available, through a similar api.
That idiom doesn't apply to this situation.
I agree with you! I'm just dealing with the data we've been given.

With AI and advanced automation, and possibly crowdsourcing, it becomes credible that any type of economic value could eventually be produced in a decentralized fashion. And one can imagine that such autonomous corporations would evolve to be so competitive (since they can afford to) that they would put all profit-driven concurrents out of business.

The economy would eventually transform into a landscape of owner-less providers of economic value, perfectly "efficient" in the capitalistic sense. That might even happen sooner than fully decentralized governments.
There is an article on that topic in the Bitcoin wiki: https://en.bitcoin.it/wiki/Agents.

I am deeply interested in the subject and would love to discuss the topic and brainstorm some possible implementations with like minded people on Freenode (#bitcoin-agent).

Most Canadians are aware of how Bombardier gets a large amounts of subsidiaries. Subsidisation is a large part of the Canadian economy so if you were to ask any alert person here if Bombardier was getting subsidised, it would range from "probably" to "yes".

I am not sure why you're angry unless you're Canadian yourself then I guess you're justified.
No, it's not unique to PHP devs. I've encountered C++ programmers that obsess over pass-by-value versus pass-by-reference and strings and minor things like that, even after that code has been written and proved to be fast enough, while ignoring the real bottlenecks that demonstrably hurt performance. A lot of times when there's a big glaring bottleneck, it needs to be solved at the macro level, by reworking the approach to macro-level features, seeing how you can get to the same place by doing fewer time-consuming operations. Those folks are penny-wise, pound-foolish.
Don't ask me, ask the OP who invented this crazy breakdown. I'm just trying to make sense of the insanity.

The interview is a 2 way street. While the company makes you jump through hoops to see if your good enough, you also have a opportunity to determine if you want to work for them.

Granted, startups only have a vague idea of what they will be programming with short periods but it helps.

Also ask "what will be my performance indicators". If they don't include "being able to very quickly learn new technologies" its hardly your fault.
