Well, it does mean your cables and dynamo can be smaller. But then you've got a new problem of coupling the cables to the load at the bottom and somehow storing loads at the top that the cables must reach past/through.
Thanks for the link. There was one sidebar about "tech in finance" that was especially illuminating to me -- half my career was at a large financial institution, and it did reflect the more positive attributes with respect to women technologists and managers described in the paper.

Another factor that may warp my perception (or alternatively, maybe yours is warped if you're in Seattle or the Bay Area) is that my career has been entirely in the Midwest. There's not very much skew at all among tech workers from the culture at large, with respect to gender equality. If anything, a male tech worker's efforts and opinions skew toward equality, relative to the average worker's efforts and opinions.

So I just see sexism problems as society problems; maybe tech companies in some tech hubs are way behind the curve of the regions where they are located? Or perhaps we shipped the most toxic programmers among us to the coasts? :)
You can create multiple OS-level threads in MRI using Thread.new. Those threads can run code at the same time, just not Ruby code. There is a function that C extensions are supposed to call while running I/O that can block, or while running CPU-intensive non-Ruby code, that releases the global lock.
I have of course wondered what it would be like to do Infobitt with a wiki, and I considered setting a wiki up for that purpose. The bottom line is that wikis lack the potential reasons for using the Infobitt format in the first place--making it easier to compete as well as collaborate, making it possible to vote on small pieces of content (as well as the ordering of the content), etc.

In other words, wiki forces users to collaborate on the same extended piece of content. This has all sorts of great effects, if enough people are participating. But it makes it harder to make short fungible pieces of content, rearrange them by vote, and do contests to discover the best version of each type.
Yes, agreed. There are some issues (mostly having to do with scalability) we have to sort out before we launch to public view without login.
It wasn't taken down. It was knocked off the front page by flags. My guess is that users feel the site is spammy.

By the way, one of several tactics that you shouldn't use on Hacker News is astroturfing. That (along with vote-rigging) are likely to alienate users and get your accounts, and your site, penalized.
Why are you using that fork of gifsicle? I went to that repo to read the homepage but it was the unchanged gifsicle README.
> While it was semi-promotional, they offered him it as a sort of compensation. Should a company not be allowed to give out their products for free for compensation?

Of course they should be able to do so, but chasing someone down who has (publicly, implicitly) expressed a desire no longer to be contacted, and for whatever reason making the contact in a forum in which it does not belong ("sorry if it was unwelcome" arguably belongs here; "how can we make it up to you?" belongs, if at all, in private communication), it seems to me is an unsavoury tactic.
Hi Colin, sorry for the typo.
This is a tool to organize notes in a tree layout. This can be a platform for many interesting features later. I wish to be able to compete with Evernote :) but this also has some unique features which I'm working on.
Yes, may the best model win!
Gotta say I really don't like all these sites that re-encode images (even more so with videos) and claim that "we can reduce filesize with, like, no quality loss using our Super Duper Compression Magic!" Because no, it's not magic, you're just re-encoding images, and possibly doing lossless optimizations on top of that (though who knows, they might even think the re-encoding is all the "optimization" an image might need already). Just look at this quick comparison I made, you can clearly see the JPG compression artifacts in the TinyJPG "optimized" version (which turned my optimized 1.27MB original JPG into a crummy-looking 431KB JPG): http://screenshotcomparison.com/comparison/101286 (this is a crop from the original image).

Rather than letting a service re-encode your images, you should rather use something that just optimizes them in an actual lossless fashion (optipng, mozjpegtran, or any service that makes use of these), and if you want to squeeze them to an even smaller size in a lossy fashion, then just save your JPGs at lower quality yourself or quantize your PNGs in a controlled fashion (pngquant does a pretty great job with that) - this is especially true with the latter, because haphazard color reduction with PNGs can lead to completely awful-looking results with higher-res images with lots of colors. Here's a comparison for that too: http://screenshotcomparison.com/comparison/101289

Bottom line: Feel free to apply lossless optimizations to your heart's content, but anything more than that you're better off just saving to lower JPG quality yourself to begin with (you'll get better results this way too since you're doing just a single lossy encode instead of two) or quantizing your PNGs yourself, provided you actually care about the quality of your images.

EDIT: Figured I could post some more images.

1. Original source image: http://blisswater.info/images/tiny/original.png (4987 KB)
2. JPG quality 90 encode: http://blisswater.info/images/tiny/encoded-q90.jpg (1033 KB) (encoded with ImageMagick using convert original.png -quality 90 encoded-q90.jpg)
2. Optimized JPG Q90: http://blisswater.info/images/tiny/encoded-q90-optimized.jpg (978 KB) (lossless optimization with mozjpegtran -copy none -outfile encoded-q90-optimized.jpg encoded-q90.jpg)
4. TinyJPG result with original.png as source: http://blisswater.info/images/tiny/encoded-tinyjpg.jpg (1581 KB)
5. TinyJPG result with encoded-q90.jpg as source: http://blisswater.info/images/tiny/encoded-q90-tinyjpg.jpg (485 KB)

As you can see by comparing 2 and 5, there is a very notable quality loss as a result of the TinyJPG re-encode. What's even more interesting is that if you want to avoid double conversion by uploading JPGs, TinyJPG will actually quantize your PNGs first (like their TinyPNG service does), as can be seen in 4 - this is something I was not expecting and find rather baffling as it quite notably alters the source image on its own even before the JPG compression.

The deluxe, and generally just unusual, hardware probably did a lot to kill Plan 9 adoption, or would have if the license hadn't got there first. Unix seems to have been successful partly because it ran on the hardware that people already owned, or hardware they would have been likely to buy anyway.

I'd really like to hear from someone about the network stack. I often see jabs at Linux's networking features in regards to FreeBSD, but Linux has a crazy comprehensive stack. Many network appliances are based on Linux kernels and I've personally worked on Linux routers. I also recall doing brief investigation into FreeBSD's networking features and came away with the impression that Linux is out ahead; is this not the case?

How does the storage stack compare? I really love ZFS and have used ZoL quite extensively in the past for a VPS/baremetal backup system and of course FreeBSD has rock solid ZFS support. But Linux has bomber RAID, LVM, dm(which lets you write you're own targets and do all kinds of awesome mapping) etc.

And then of course there are "containers". I'm aware of jails and they are much tested but I saw the other day that they don't have cgroup type features to allow controlling RAM and CPU usage? Namespaces? Is it the case that Linux containers are overtaking jails on the features front?

I really like the idea of FreeBSD and I have bought "The Design and Implementation of the FreeBSD Operating System"(which I ought to start reading) but I'll admit to not knowing a whole lot about it. Most of the topics that come up in comparison discussions seem a bit more superficial than what I'm interested in.
There's already a (slow) bus line parallel to the rail line. Demand is high enough to justify both.

Even if it's a bad idea, I still prefer a community that encourages people to try anyway and make things for its own sake. HN culture felt much more positive and constructive when I joined a few years ago. While that ethos is still present, there's an unfortunate tendency for the snark to rise to the top.

As I have said several times before, Wikipedia doesn't follow Surowiecki's rules for "wisdom of crowds" effects.

The Infobitt model has an advantage over wikis that will enable a wisdom of crowds effect. People contribute and vote independently of each other, not by having to agree on a single version of the content. Yes, there can be comments, and that will have a biasing effect; but what people say in comments is obviously not as important as their votes, which they can exercise independently of each other and comments.

Also, since the pieces of content are short and fungible, they are therefore capable of being subject to contests. We can submit competing versions of facts, and the best can rise to the top.

Finally, every fact in Infobitt has to be sourced, and the fact is a summary of the source; and (soon) we'll be able to compete to write the best summary. So, to be sure, we'll have bad summaries occasionally, but generally I think we'll have good ones, once we've built the community up some more.

I would imagine that items that are very important and have short deadlines would be the least likely to be farmed out by a company. Certainly, they would be the least likely to be made available to companies with no shared history.

If I wanted to pursue jobs like these, I would come up with a pitch and introduce myself to small contracting companies. You'll probably have more luck if you can provide evidence of your prior successes and can demonstrate a very niche skill.

You have a shaft 1km or 1.5km deep. You can afford to stack a lot of weights vertically. Imagine each has a hole running through the middle, where the cable runs, and a mechanism whereby the weight can engage/disengage from the cable. The cable forms a circular loop that passes through all the weights from the top of the shaft to the bottom, then circles around past a large pulley and back to the top, completing the loop.

At the top of the shaft there would be hefty prongs that retract when the weight needs to start dropping, and when the weight returns during a recharge cycle, the prongs reinsert themselves in to the shaft when the weight is lifted back into position.

Most likely each weight would have a "C" cross section with a nearly closed mouth -- just a slot from the edge of the weight to the larger central opening so that the weight can be removed/replaced from the cable if needed.
Yeah, I see these things rolling out as fine-grained additions to buses. Public transport in the U.S. sucks unless you live in the cities..it sucks in the suburbs too.

Always negotiate your salary. I have gotten 10% higher starting salaries a half dozen times in my career simply by asking.

The hardest part is just being ballsy enough to ask.

The responses in that Dropbox thread were pretty solid though. To all the naysayers, I mean. It's sort of a ritual format to test any new idea with the back and forth. That in and of itself isn't a problem.

Real problems: Dismissive people who don't/can't/wont listen to good responses. Good founders/ideas but just really bad at communicating. Those are basically the type i and type ii errors of this format.[1]

I don't think that's true. This is likely one of those problems whose solution accelerates after introduction.

Let's assume that 99% of the problem is solved (probably not, but we're worst-casing here). The problem is that you need to stumble on a 1% case and fail in order to fix that bug. At this point, I suspect that we're probably limited by the fact that buggy cases just aren't coming up often enough for the small number of autonomous vehicles that exist.

Look at what happened in the DARPA challenge. The first year, nobody got anywhere. It didn't take very long until that challenge went from nobody completed to worrying about things actually moving too quickly.
Objects become art
Unfortunately for plan-9 the world has moved on. Plan 9 will (and already has) influence many follow-ons but it is now behind the times in some aspects and still ahead in others.

Vmware and other virtualization vendors as well as the various cluster computing solutions are capable of live process migration, checkpointing and a ton of other nice features that Plan-9 simply doesn't have because at the time it was to be an improvement on Unix and 'Beowulf' was still just the name of a character in a story, Amazon was a figment of Jeff Bezos' imagination and the Google guys were still playing with their Lego.

To really revive Plan-9 would imply diverting resource from a lot of projects that have progressed far beyond where Plan-9 has been stuck for well over a decade. So as much as I love the whole idea behind Plan-9 and the way they've made a better unix I fear that they will never be able to get the kind of push they need to gain parity. Pity, really.

Plan-9 could have been where Linux is now if they had caught the wind at the right time. Community is the single most important factor in whether or not a technology will succeed in the longer term or not. Linus Torvalds beat all of the incumbents by doing one simple thing: opening up the source right from day #1 when the barrier to entry was sufficiently low that he got buy-in from a lot of capable people.
How hard is it to re-program these? If you needed a device with GSM and just a few GPIO, this makes more sense than an Arduino + GSM shield. In fact, the entire phone is cheaper than a GSM shield. It would even make sense to use this phone solely fore GSM comms and connect to some other µc over the UART.
Are you implying that Elon Musk doesn't have any achievements? Co-founding PayPal and then following up with Tesla and SpaceX aren't too shabby, considering that all three of those companies are profitable. He's a little dramatic pushing his "big ideas," but he's never been fired from his position as CEO as Jobs once was.
Ok. So it's obvious that the similarities between Uber and Airbnb are the multi-billion dollar valuations and the regulatory red-tape issues. But it seems that the major difference isn't just that Uber is portrayed as Darth Vader to Airbnb's Skywalker today. It's that Uber came from seasoned entrepeneurs vs Airbnbs first-timers at the start. The same goes with Dropbox. Coming from an accelerator program surrounds you with dozens of people struggling and breeds more of a friendly culture. Perhaps it could be that there are "quasi" authority figures at the beginning in the form of partners who "accept" the companies into the program - whereas Uber had no such authority during its formation.

Of course, the sample size of 2 or 3 companies is just too small to draw definitive conclusions. Rap Genius had public issues and they came through the same program as Airbnb. Maybe Airbnb sees how much bad press Uber is getting and so is trying to do everything it can to seem friendly.
I have had my Anova for just a little over a week, and I think this is missing something. Yes, the "sear then oven" technique gives you a good steak. The sous vide steak I made tonight is the best home steak I have had - more tender than the cast iron steaks I have done. It's also easier - I can make sides while the steaks cook in the water bath, and my window to get them out and still have them at the doneness I want is literally hours, whereas I have to precisely time when I I remove the steaks from the ocen to get the right internal temperature.

It wasn't even that deluxe at the time (especially not the display hardware). The hardware didn't help, the license didn't help, keeping it behind closed doors is what killed it.

The first 'ok to use commercially' release was in 2000, by the Linux had eaten up any market that Plan-9 could have conceivably had.
Thanks for the kind words, I too think that laser-cutter combined with maple wood is sort of like a home cooked meal :)

I haven't actually gotten into 3D printing, and I find laser-cutting much less intimidating, because you are dealing with 2D at all times. Of course it has it's limitations, but you can build very complex 3D structures out of 2D cut-out objects.

This models the hiring manager like he is a professor or judge of a competition. He isn't. He does not care about truth or light or merit or beauty, to a first approximation. He is just a corporate officer with a mandate to buy certain industrial inputs while staying within a budget.

He wants to purchase your services and makes a bid. That bid will virtually never consume the entire budget, because he has the rational expectation that he does not need to spend the entire budget to acquire your services.

You say "I will offer you my services, but the bid was too low." If he is still willing to purchase your services at the higher number, he accepts. Otherwise, a few words are exchanged, and he re-offers the original bid.

People make salary negotiation feel like it is a Greek tragedy. It is not. It is a routine financial transaction. The really big "but!" attached to that is that it is the routine financial transaction which will have the largest impact on your personal finances, by several orders of magnitude, at least until you decide to purchase property.

But what's disturbing about these replies to my comment is how many people are almost gleeful to have the government tracking every movement they make by making almost hysterically silly arguments that it's being done today.

Just the fact that "well, it's done today, so I'm OK with it" is disturbing on what used to be site for Hackers.
