How we got from idea to startup
So how many of these things have been changed since the article was published 1,5 years ago?

After looking through my settings, more or less all of them, with the exception of cache management, it seems.

The language used, including the brand name, make it sound like it's a leap ahead of the competition. It has our attention especially now with this large raise. Hoping it's truly a decent improvement.
Shoptimisation – Modeling Supermarket Traffic Patterns
I think this was just a bad timing. When deciding to withhold treatment for Dr. Khan they weren't aware that the next patients in line were two white men - a situation they explicitly wanted to avoid.
Yes. And there was - on HN - much wailing and gnashing of teeth.
I didn't want to say that but yes, it looks like marketing.

Truly looking forward to see what they're developing.
Bonus: The linked Google Plus post is by Terence Tao.
Can you explain why? It would be beneficial to understand.
Indeed, the big-data winter is just waiting to happen, after all the hot air that has been produced (& continues to be). Anyway, it's very nice to see the media hype put in perspective for a change.

I can see how some people might feel like being between a rock and a hard place: The data firehoses are all in place, our key-value stores are getting fuller by the hour, and we're supposed to sit and wait for decades before we'll be able to make any sense of it? I wouldn't be surprised if some will much rather play roulette today than make a sure bet in 10+ yrs.

In most cases you only need a handful of functions - crypto_box_keypair/crypto_box/crypto_box_open for public key crypto and crypto_secretbox/crypto_secretbox_open for private key crypto. It is way simpler than any other crypt library I have used.
Yeah because those who are aware how those things work can totally waste their time downloading addons to do basic things.

Common sense: you don't know what this control is for? DON'T touch it. Or touch it and face the consequences (learning's got to start somewhere, right?).

This article seems to encourage apple's way of thinking ('simple', 'just works') and this is one of the main reasons for me (and many other people, I reckon) to ignore all their products completely. You want to go this way? fine. Don't expect anyone technically-literate to use your thingie though (because it becomes harder to use for debugging and all those things than, say, Chrome). Also:

> Is it really worth having a preference panel that benefits fewer than 2% of users overall?

and then

> Even 1% of a few hundred million isn’t a trivial number of people.

Decide on it already :)
Has anyone given any thought to what the Police will use for riot control if tear gas is banned? I have been on the receiving end of Tear Gas. It was not a pleasant experience . However after about an hour I was back on my feet and good to go. As much as I didn't care for the tear gas, it would still cause less damage to a protester to get gassed than getting hit by a rubber bullet or a police baton.
Definitely got my attention.

:) Funny thing I noticed, going through the job descriptions - Physical Requirements for HR Generalist[1]:

> While performing the duties of this job, the employee is regularly required to sit;use hands to finger, handle, or feel and talk or hear. The employee is frequently required to reach with hands and arms. The employee is occasionally required to stand;walk;climb or balance;stoop, kneel, crouch, or crawl and taste or smell.

> The employee must regularly lift and/or move up to 10 pounds, frequently lift and/or move up to 25 pounds and occasionally lift and/or move up to 50 pounds.

> Specific vision abilities required by this job include close vision, distance vision, color vision, peripheral vision, depth perception and ability to adjust focus.

As I recall, the original ls didn't have that feature.

Examining the characteristics of the output stream and changing behavior is another "rule" that is not mentioned often. Another example is buffering the output to a large block if sending to a pipe, but making it line-buffered if going to a terminal.
Having non-skateboarders demonstrate their invention was a poor choice. They seriously lack the balance needed to make this look appealing.

Yeah, I love jq. With a tool like that, I'd actually like to have an option for standard *nix tools to output JSON. Dealing with structured output would be far easier than counting which columns need to be extracted, using sed to split things, etc.
Ah, the curiously named "atavistic" did bring out one thing I may have not made clear: when talking about "arguing your point in favor of things like helping people bleed out faster, because we're trying to "save lives" here", one idea is that the target is indeed a "bad guy", and the sooner that bad guy is stopped, the fewer (additional) people he will wound or kill.

This is often critical for a "good guy" in close combat with one or more "bad guys", and generally particularly critical in the politically motivated hostage situations which prompted the discussion, where killing the hostages is a frequently desired eventual outcome of the "bad guys".

Which in my opinion definitively makes them "bad guys", to the point of my not being in the least upset at those higher ups who give sub rosa orders that they'd prefer none of the hostage takers survive.

The point you make is also strong, very frequently so in hostage taking situations, which is one reason good police snipers train obsessively. Important enough that I brought it up in my first paragraph of exposition in this discussion, as well as in, say, a recent one on the quality of the firearms leadership of NYC police, who for a long while saddled their men with FMJ bullets, to the determent of everyone but the self-satisfied and grossly ignorant anointed.
We have had Personal identity number system in Sweden since 1947. Maybe because we where spared most of the atrocities of WWII I don't know of any strong resistance against it. But it is also combined with laws that strongly forbid registration of some types of information, such as ethnic group or political leaning.

And it is oh so convenient! I'm moving in a few weeks, and I had to fill in a form on a website and the tax authorities sent me some papers to sign and return. And that is all! Now all government agencies, the banks and larger companies that I deal with, and all magazines I subscribe to will have my new correct address in their system within days.
My problem with the argument of moving everything into an addon is that I don't care for installing 13 addons with no permissions list (in firefox at least) and no way to keep them away from my browsing activity.

Hey Michael,

Thanks again for the advice, I have added a 1-click login to the demo account on the landing page.
Maybe it is a glimpse into internal politicking and budget wars. It's harder to cut funding to a project like this if people are beating down your door asking about it. But they'll only do that if they've been given some tantalising details about it.
You can use the PowerShell ISE. Which has tabs and you can just hide the script pane to get only the console itself. Startup time is a bit hefty, but if you have tabs you probably create new tabs way more often than the tab container.

Especially for PowerShell the whole problem that Console2, etc. have is trivial, as you have an API to create a host application instead of relying on polling a hidden console window. The console host is just one of those hosts.

What makes you think human brain isn't just an ensemble of hundreds of different specialized algorithms?

Trying to emulate biological brains might not be the way forward. People tried to fly by constructing bird-like feathers and wings - it obviously didn't work. We had to understand the underlying principles governing flight. The same applies to creating neural networks.

There's some underlying principle the brain uses. It doesn't mean we have to crack brain structure to achieve strong intelligence.

We should look for inspiration in biological systems but we should not try to copy them.
LOL! Actually I did, but I was at the laptop at the time and didn't scroll so I missed it... :D
> Most fusion approaches, including ITER, can only work if our current physics theories are flawed.

Yeah this isn't true at all. Moreover, the US isn't funding fusion well at all - it has repeatedly threatened to pull out of ITER, was late to come on board, and has thrown only token amounts of cash at other projects. The Z-Pinch also is not a fusion device, and NIF was built to study atomic weaponry implosion physics, with inertial confinement thrown in for good publicity more then anything else.

Moreover, ITER will work perfectly well, and Q > 1 fusion has been demonstrated in previous, smaller tokamaks (it is just not a practical power source). Engineering problems are very different to "fundamental physics", and there's no particular reason to think that we can't build a suitable neutron absorber for a tokamak, just that it's tricky.
You don't need to read the article. The title is the least whitewashed portion, it just gets more ridiculous from there.
I hate it when a program has a huge --help output, and the man page is nearly empty, and says "see the --help option for more details." Things like examples, see also, etc. are very valuable to someone trying to figure out how to use a program....
Good work, this looks like a great resource. I've always found your hansard alerts incredibly useful. Another interesting resource for Australian politics is the ABC's (relatively) new FactCheck service (http://www.abc.net.au/news/factcheck).
Beyond Microbenchmarks: breakthrough container performance with Tesla efficiency
Their technology trademark is 'Dynamic Digitized Lightfield Signal'. A lightfield camera has multiple lenses to record multiple focal points simultaneously. Have they found a way to reverse this concept, 'project' to a wearable an eye refocusable image? Their list of job openings leads to a lot of possibilities.
That's still pretty damn expensive. Ever leave a pot on the stove boiling and let it run out, the amount of precipitate is surprising. Do that on millions of gallons of water and you end up with a lot of material that needs cleaned often and isn't easy to get off.
EFF's Updated Know Your Rights Guide
Understanding TCP under poor network coverage
This is an old article dated early 2012. The current govt is very responsive to citizens.
I have been using the tried and true ostrich technique to avoid the topic (the whole systemd debate). But honestly it feels like the file on the right is a whole lot more opaque. If (or when) it goes horribly wrong, I am not certain I would know where to start, as compared to a simple script file where I would walk it / debug it.
This is a wildly inappropriate comparison. For one thing, Craig Venter didn't necessarily produce a "good" genome, and his approach wasn't objectively better at the time.

For another, it was hardly a problem of engineering at that point, the basic chemistry was well known and well understood. It was very much a problem of data-processing and logistics to get it all done though.
This wouldn't do a thing to oil wealth. Fusion displaces coal, not oil.

Has anyone got an answer for 7? I think I have the rest of them, (whether I'm correct or not obviously remains to be seen).
As a PM, this would work for me.
I always thought that the key was to mash with an appropriate volume of liquor (or 'water' for those that don't enjoy the brewing jargon): if you chuck all the liquor in (full-volume mashing I think it's called), the thin mash means that there's less contact between the enzymes and the starches which I would expect to result in a different chemical composition.

Batch sparging on the other hand (following a mash with a regular ratio of liquor/grain - but rather than slowly rinsing the grains with sparge-temperature liquor, you fill your mash tun with your full volume of liquor at sparge temperature) may affect efficiency (positively or negatively), but shouldn't change the quality.

I've enjoyed some fine batch-sparged beers!

Oh and as for the OP's point about a beer taking three hours... I wish! For me it's more like 8 with all the cleaning and fiddling around in my tiny brewing space!

In this context, what would you define as 'product'? I'm curious as I hear it mentioned and it sounds fun, but conjours up mental images of inventing the next Gilette razor.
Knowing something is definitely feasible is very, very different to trying to invent the first working prototype.

i.e. knowing that a particular design of plane does actually fly, means you can make very different assumptions about information you get from looking at it's shape.
Hopefully Microsoft under the new CEO will reconsider XNA and update it for Visual Studio 2013. It is such a great platform for people that prefer coding their games instead of using a drag/drop Unity style.
Try running it under qemu[1] or bochs[2]. A "virtual machine" software such as VMWare or Virtualbox is not the same as a low-level "bare metal" CPU emulator such as the two I suggested. The latter programs make assumptions about how the guest OS will behave that probably aren't valid for this project.

I suggest starting with bochs since this project has a bochsrc.txt in the git root that will be automatically picked up if you just run "bochs" in that directory.

FYI beef spikes insulin higher than rice does. Insulin is released when we eat any food, both stopping the mobilization of fat and driving this food energy into cells to power metabolism. This is analogous to not drawing money out of your savings when you have cash in your hand.

As far as the spiking of insulin, it's just proportional to the rate in which food-energy enters the blood stream. It's not itself bad, and only when it does not work like this do we identify it as a problem (eg. diabetes). But there's this pervasive misunderstanding that spiking insulin is what causes insulin resistance. It's not from the insulin directly, it's from the chronic overfeeding (or other health problems) that's causing the insulin to stay high and drive the resistance adaptation. It's similar to the cholesterol myths. High cholesterol can be a signal that your immune system is dealing with inflammation; but it's that inflammation that is the problem, not the cholesterol.

My point was that the idea that carbs are somehow worse is fallacious. Chronically eating too much can contribute to insulin insensitivity; what you eat is much less important than how much you eat.

If you really want to keep insulin low and maximize fat mobility, nothing beats not eating anything at all. Light exercise like walking in a fasted state (more intense exercise shifts metabolism away from fat and back to fast-energy carbs) is a very effective tactic to target fat loss. But of course this needs to happen in the context of appropriate daily caloric intake. Never subjugate fundamental principles to minor details.
I really don't understand how it is a problem, these options are surely useful for a portion of the userbase otherwise they would not be displayed.
I'm pretty sure people browsing with a 33k modem connection would enjoy disabling images so everything could be faster and you can find examples for any item of this list.

All these options are under the configuration menu anyway so no inexperienced user are not going to go in this menu anyway... I don't really see the point this article is trying to make.
Off topic, but did anyone else notice that the BBC's video player's audio control goes to eleven?
One change I'd like to see in education is a wider use of competency-based education. In this approach, students earn their credit when they have mastered the material for a course, not just at the end of a semester.

This approach can be made to work for high-performing students, and low-performing students. Master the material in a course in half the traditional time? Earn your credit then. Need another month to master the material? Take that time, and earn your credit when you're competent in the material.

Most of us know the adage that "work expands to fill the time we are given to accomplish it". This is perhaps nowhere more true than in school. Take the time component out of learning assessment, and let people progress at their own pace. Most students are capable of working much more efficiently than they do, but there's no incentive to do so. In fact, there's a disincentive for most people; if you finish early, the teacher will probably just give you more work. Some good teachers motivate strong students to finish early so they can move on to more interesting work; I've heard far more stories of teachers who respond to early completion by just offering more of the same work.

If you're curious about this, a good place to start reading is on the Competency Works site:

Counterpoint on the TV on SKY News from Dr. Mark Bacon from "Spinal Research" who says that this is nothing new, that it is not as significant as a "man walking on the moon" as has been claimed.

He says that this is essentially a feasibility study showing safety, and that it was the unique situation of the patient where the cut was very narrow and clean that allowed this to happen; most other spinal injuries damage much more of the spinal column. He said he also wants to quantify exactly how much of the shown result was directly a result of the surgery. The patient had lots of different treatments and they don't know how much those had an effect.

However, when the interviewer said, "although you've added a note of caution there, should people with these kinds of injuries have a bit more hope now that this news has come out?" the response was, "absolutely, it shows that we are making inroads into this. This area, even just a few years ago was thought to be dead, but now we are making clinical trials."

Edit: Changed it from BBC News to SKY News. Oops.

Safety. What is there are horrible side effects that only show after 12/18/24 months and suddenly the lives of 100's of people are ruined? You could make that clear to people and if they want to participate despite the warnings let them but most people aren't well informed enough to make a rational decision.
The codebase is so small that it's quite easy to take a look to answer the questions:

* no networking at all

* performance - doing what?

* file primitives are implemented purely in Lua, and what is currently there resembles a pre-initialized ramfs. Closing a file is a NOP, the concept of numerical file descriptors is not fully implemented yet. So - no block devices yet.

* aside from file primitives, you have lua coroutines as the core of the scheduling, inb()/outb() (bytewise port I/O), and putpixel/clearscreen in the API implemented in C, as well as basic keyboard handling (using inb/outb wrappers) and graphics primitives (using putpixel/clearscreen) implemented in Lua.

I suggest to take a quick peek at luakernel.c and luakernel.lua in the codebase.
