But a linear encoder would work with a Gray code that had the restriction AND it would work with a Gray code that did not have the restriction. So there's no benefit for the linear encoder.
95% efficient each way, it does sound a bit much.
This came up a long time ago. It doesn't work well, the amount energy it stores is simply too low. I've seen a calculation somewhere, but it's too late here so can't reproduce - does anyone remember?

Edit:

here it is.

I suspect they plan on recovering the power with a generator. So the input shaft to the generator has to rotate. With a deeper hole, you get more 'clicks' on the generator so you can produce power for a longer period of time before having to pull the weight back up.
I have no idea where he gets the basis for his first couple of sentences.
The energy density for gravity is just immensely small, that's why you need dams holding back rivers to use them to generate electricity. For a 1km hole (that's in the middle of their 500m - 1500m range) you have an energy density of 10kJ/kg of the weight that stores the energy. The energy stored in a Tesla roadster battery pack is around 50kWh which is 180MJ. This means that you need a 18,000kg weight in a 1km deep (immovable) hole to have the equivalent of a Roadster battery pack. I'd go with the battery pack.
Today, the majority of grid energy storage is done using pumped-storage hydroelectricity (PSH). "PSH reported energy efficiency varies in practice between 70% and 80%, with some claiming up to 87%." [1]

> very few companies seem to be out here

Are you able to move? There isn't exactly a shortage of dev jobs if you can relocate, and in places where the shortage is on the labor pool size (like the SF bay area), you shouldn't have trouble finding a company that will help you with the move. The cost of living is higher, but you can almost certainly compensate for that by taking a higher paying job.

Just putting that out there; it doesn't seem like there's much reason for an engineer to feel constrained by a lack of job opportunities in today's climate.
I'm in the US, so it's possible all this may not apply, but my two cents:

What has been your job hunting strategy so far? What kinds of positions have you been looking for?

If you're just sending your resume online you need to do a lot more. Don't hesitate to reach out to recruiters or individuals at companies directly (but be professional about it). You have to treat finding a job as a job in of itself. Track leads, use multiple forms of communication (online, email, social, snail mail, in person even), and follow up on positions you apply to if you don't hear back in a reasonable amount of time.

Personally, I've found the best leads are through people I already know or people I meet. I would look if there are any meetups or networking events nearby you can attend. If that doesn't work, perhaps you can virtually create a presence online by contributing to open projects or be more active on visible forums (HN, Stack Overflow, etc.).

Also, maybe you can broaden your scope to a wider array of positions so you can just get started working somewhere. Sometimes once you start at a company other positions open up that you can transition too.

That aside, a few notes on your site:

* The Voter link doesn't work.

* The Mlinar link opens a page with the same CS:GO language.

* Your grammar is a bit stilted. I'm guessing English isn't your native language, but if English speakers are your your target audience you may want to clean it up.

* The individual portfolio pages need richer descriptions of the kind of work you were doing.

* You have a few mailto links, but you don't actually list your email anywhere.
A large group is often dumber than its weakest link.

> Companies that never grow up tend to go the way of Groupon or MySpace, two now-faded comets. As good as Uber’s app is, there are limits to how much bad publicity it can absorb before it hurts the bottom line.

> At Uber, the inmates are running the asylum. That needs to change, while there’s still time.

Neither of the failure of the given examples had anything necessarily to do with bad publicity so they are unrelated to Uber. Groupon had a bad business model, but it still makes a ton of revenue.

I have the impression here that someone is trying to oust someone at Uber for whatever reason. If the shareholders had a problem with the execs, they'd make it known. Internet mobs can be effective, but why is the mob being unleashed against Uber? Who is benefiting?
What does this do better/differently than an ADFS set up?
You're right. I was thinking of gfx xrender.
This article is just terrible. Their argument is that Google is not a perfect judge of correct information and does not instantly return all relevant facts.

No shit. In fact despite the negative tone of the article, when I googled "who is ariana grande?", their explicit question, Google returns a Knowledge Graph box from IMDB. A relatively authoritative source, telling me precisely the information I would have expected.
One wonders how this particular correlation rates in comparison with other better-known correlations: youth, maleness, poverty, stress, solitude, access to firearms. I suspect that it would kind of disappear into the noise. I wonder if investigating the effect of poverty (Utah is 40th in per-capita GDP by state, and has the 4th highest unemployment rate) and access to firearms in this particular case might be a bit more diagnostic.
OK, a typical mine hoist is about 10 metric tons. 10 metric tons descending at 1m/sec is very close to 100KW. So a 1000 meter deep hole can deliver 100KW for 1000 seconds, or 27 KWH. That's about $3 worth of electricity, and about 1/3 of the battery capacity of a Tesla Model S with the large batter option.

Numbers not looking reasonable for this concept.
Even a new distro is not a new OS (in opposite to what they claim).
In my experience it all comes down to performance and tunability. Our personal preferences are just that, personal.

Linux has vsyscalls which makes it performant for the typical LAMP stack. If you profile a PHP Zend framework "hello world" app it makes 20k+ calls to gettimeofday(), which is very slow on FreeBSD in comparison. Throw a couple hundred requests/s and you saturate the CPU for no good reason.

FreeBSD needs business support in order to maintain funding, and be a relevant competitor to Linux. If a developer were to pick a popular application stack like node and identify significant performance gains it would make waves.

QuikClot is very nice. I had the opportunity to use the 2013 formulation for the first time last weekend when someone in my kitchen was cleaning a blender with their finger. The blender was not unplugged and, well, turned on. Their finger had multiple deep lacerations down to the adipose tissue. (Fortunately this was not me!)

As one of the other posters in this thread said, the 2013 formulation is impregnated dry gauze. It worked very quickly to stop the bleeding with no heat--the top left of the package, in fact, is labeled "heat free."

We ended up going to the Palo Alto Medical Center's urgent care clinic and they applied glue instead of stitches because of the lacerations' proximity to the fingernail. The nurse was surprised I had QuikClot on hand and mistakenly thought it worked by "cauterizing the wound."

The downside is the price, about $40 for the combat gauze I used.
The answer to that is that systemd is much more than an init system.
Actually article contain argumentation that forking can't save software if this software was designed wrong.
Is a 500m-1500m shaft is pretty much going to fill with water? I could see a well designed weight being able to work in water (although water turbulence would erode the shaft walls. I don't see how air compression would solve this.

The principle however of storing energy by raising a weight could also be used anywhere with a steep enough hill/cliff/montain and the weight could in theory be on a rail not just suspended.

Efficiency would potentially not be on par, however linked into solar/wind systems this is less about efficiency and more about creating a 1MW long term battery with a lifetime of 50+ years.

Guessing cost of digging and maintaining a hole compared to installing a guide rail is significantly higher.
Okay, so energy density is low - but what are the costs like?

If you can build one of these cheaply, and the running costs are trivial, then it's worth doing.

How many of them would you need to smooth out the energy of a wind farm, for instance?
That's true. Unfortunately, current Tesla battery packs use lithium, which isn't super-abundant in Earth's crust.

That's why companies like Ambri are looking at using other materials in the batteries they're developing for grid energy storage.
Same can be said for consumerism. Some argue its a waste and an environmental disaster that people change phones every couple of years, but it drives a technological development which trickles down to less lucrative, glamorous and mass market applications. No one would develop something like a Snapdragon processor just for medical devices, but once the technology is pioneered on phones, it can definitely be reused.

Besides, our existence has no reason or cause other than having fun. And motorsport is awesome fun and entertainment.
Boosted used as an adjective where I come from means stolen.

What is the lifetime on the wheels? At $1500 I would almost want a grease port to maintain it on my own.
It sounds to me then like what I was guessing is true -- the difference between the FreeBSD kernel and the Linux kernel, for most purposes, is of less importance than the choices made by the particular distro (FreeBSD or Linux distro of choice).

I'm curious if anyone who knows more than me would disagree, though (maybe for some purposes?).
Sometimes. There's plenty of technical competition between engine manufacturers, but in most other areas the rules are so strict that there's little room for useful creativity.
Very well said. I've started a few month ago on an AI/Bot for 0AD an open source game. Scripting language is JavaScript running on SpiderMonkey. So far I've accumulated thousands of locs, learned a lot about writing fast code against a specific engine and have barely more than a framework. But I still remember the moment the bot did it's first baby steps and actually build a structure to train some scouts and started exploring the map.

Also it became a decent exercise in dealing with abstraction. The code base just explodes if you do not follow DRY - strictly.
If you eat a cat, do you then contain a cat? No, you contain products of digesting a cat. The supposed cause/effect looks like magical thinking in hindsight.
I'm baffled too. Language is central to culture. If you can't pick up a pencil or pen and contruct the letter forms that make up the alphabet reasonably fluently because you weren't taught properly, isn't that a bit depressing? Writing can encourage a love of lettering and letter forms. Sure, you can take this up in later years but it's better to learn from an early age. And as another poster says, learning to control a pen with precision is a valuable motor skill. Anyway, it's not clear in the article if this is just about cursive handwriting or all handwriting.
Been attempted before. Its interesting that below ground is preferable to above ground. Water tables in many places will be a problem.
I think they should open source Trident, which would be more appealing to compete with the mess that Webkit has become. But who knows if Trident isn't already a mess itself. I do like how snappy IE11 renders webpages though, perhaps something to do with how they implemented Direct2D.
Why aren't we talking about OpenBSD vs. Linux?
I mean, it's the only OS I trust anymore.
Does it really matter?

You should be able to get millions of rotations from a single centimetre hole, given that the mass is large enough and you have a good gear ratio..
I still not sure about the details, and I don't like how they use the word "cheap" there.

Nevertheless, the density of Lead is 11.35 g/cm3 (the density of water is 1 g/cm3). The densest element in this table is Osmium with 22.6. So replacing if you replace a Lead weight with a more expensive weight you only gain x2.

http://www.lenntech.com/periodic-chart-elements/density.htm
They only analysed 49 research findings? Pah! Far too few to draw any real conclusions :)
So, what are the rules of gongkai? That might have been useful to include in the article.
I suppose they plan on using a transmission mechanism that will turn one meter down to as many turns as you want anyway, so I guess the depth of the hole is at least partially determined by how good a transmission mechanism you can afford. But since they explicitly say the hole will be the most expensive part, I'm not so sure.

i guess you didnt understand my point. you do not obtain the same result in a pan as you do via sous vide. one does not replace the other.

have you ever used a sous vide machine? if you had, you'd probably better understand the point im making.
Very misleading title. This is not about a GC speed up, it is about a reduction in pause time. The GC a itself is eating as many cycles as before (possibly more due to the cost of making things incremental) and they are clear about this in the article.
> Size seems like a really odd thing to bring up since every mainstream linux distro's "basic" installation is larger than the full OS of any of the four BSDs.

I don't think that's entirely true. The Debian install I do by default, with no tasksel tasks selected, is very minimal. I haven't checked recently how large it is (and one of the reasons I am considering moving away is that I suspect the minimal required system has been growing with the adoption of things like systemd), but I remember a few years ago noting that it was a fair bit smaller than a clean OpenBSD install. That's not including X and compilers IIRC.

Also, as I understand it, Arch Linux is becoming quite popular and it is also pretty spartan by default.

(Not that I think this really matters for most cases (embedded excepted); I would like to be able to uninstall tcsh, though.)

You're losing torque with every gear reduction, and I believe that current out of a generator is a function of torque. So there's some happy medium between hole depth & transmission ratio for the amount of power they want to generate.
One interesting thing to note is that the title Doubling Saturated Fat in the Diet Does Not Increase Saturated Fat in Blood does not logically contradict the notion that radically reducing saturated fat in the diet decreases saturated fat in blood. It's possible that once you reach a certain consumption point you're doing as much as you can do.

I'd want to read the study in detail before commenting further. I'm a little surprised they started with people with metabolic syndrome, which could mean a lot of things and lead to a lot of craziness.
This rant makes some valid points. But if you decide to reinvent a wheel, you should be fully aware of what you're getting into, and the responsibility you're taking on.

For example, if you decide to create a new UI toolkit, by which I mean something that draws the widgets and handles low-level input events itself as opposed to a wrapper over one or more other such toolkits, then you need to be prepared to deal with things like accessibility for users with disabilities. This includes blind users who require a screen reader, but also people with mobility impairments who need to use alternate input devices, speech recognition, or the like. This means implementing the accessibility APIs of your host platform(s), which isn't necessarily easy. If you release an application with your own home-grown toolkit (or someone else's) that doesn't implement accessibility, then your app will be unusable to some percentage of people who need or want to use it. That's probably not too bad if you're developing a game, but is more of a problem if someone needs to use your app to do their job, take a class, do business with a particular company, or any of the other increasing number of important functions that involve software.

Or, to throw out a few other examples beyond my usual soapbox: If you're writing a new crypto library (the post did reference OpenSSL), make sure you handle side channel attacks and all the other gotchas that come with crypto. If you're rolling your own HTML templating thing, make sure it's not susceptible to XSS. If you're creating a new database or other form of data persistence, make sure the persistent data isn't easily corrupted. And so on.

Regarding the part about "most programmers", I'd venture to say that for most developers of new applications, it's best to build on proven, mature infrastructure as much as possible, and avoid gratuitous reinvention.
One resource I would recommend is the Startups For the Rest of Us podcast.

FreeBSD changed how the packages work last year

You now get the regular repository (binary packages updated once per week), or the 'Quarterly Branch' (a known-good snapshot of the packages, with security updates)

Or you can build your self from ports (or build your own packages using poudriere), which is up-to-the-minute bleeding edge.
Tungsten is near 20g/cm3 and is much more reasonable as far as price is concerned (Osmium is basically a precious metal). I'm not sure sparing a few hundred meters of hole digging is worth gathering tons of tungsten, but I would not be surprised if it was.

There are 3 options:
1) Two sites, "mobile" and "desktop", both responsive;
2) One site, responsive;

Option 1 is the best and most expensive to implement, 3 is worst and almost same expensive. So "optimal" is 2, when best is 1.
Ohh, and Re: ZFS using a lot of ram: You can limit it. The default is 95% of ram, and that is too high in all cases except a dedicated file server. PCBSD in 10.1 (released this week), changed the default to be much more conservative, since on a desktop/laptop type system, you probably only want to spend a fraction of your ram on increasing the speed of the file system.
If so, I wonder why the site doesn't just say "to run Hangouts on a computer, just load a hangout in your browser" (possibly with a link to the right place). It seems such an easy thing to fix, and it was pointed out publicly, yet no change has been made.

It seems unlikely to me that the assumption is that people that pick "computer" over "smartphone" distinctly want a native app as opposed to just running hangouts in the easiest way possible. All they did was click on "get hangouts".

"The big advantage of driving to work over taking the bus is time. A bus ride just takes longer: walking to the stop, waiting for the bus, picking up passengers, all while toughing out the same traffic as cars."

Generally, yes, driving will always beat a bus. Train is always the way to go, as there is no traffic on the tracks (a majority of the time).

To me, it's a common misconception that driving is quicker. In Chicago, driving is almost never quicker (due to traffic), and regardless, it's always wasted time. You can't DO anything while you're driving. Taking the bus or the L, at least you can work on what you need to work on.

The UCI machine learning repository [1] contains a wealth of data sets intended to be used for machine learning. Many of the data sets have had analyses performed on them that could be considered canonical. For example, the Abalone dataset's [2] associated problem is the prediction of a specimen's age, given its measurements. The problem has been analysed thoroughly; a cursory Google search for "Abalone data set" reveals that plenty of people have considered the problem.

Also Amazon (via AWS) [3] have made it really easy to access public data sets.
