Hey, great job!
A real test of an idea could often be it's potential to generate revenue.

I understand that it is a side-project and you may have different motivations.

But I guess it is even more reasonable for you to try implementing a business model.
There is not much to lose (given you don't end up putting desperate adverts all over the app... Duh!)
As an example, the 'karma-as-commodity' model might just work.

Point here being that I don't see something as valuable to a potential employer as a person who can write amazing apps and make some solid money out of it.
MIT ordered the renaming of this? It's sad when learning institutions act like corporations.
Thanks for posting the video! Do you have any knowledge of the technical details? I only know a bit about inferno and am specifically wondering:

- is there support for mounting a filesystem accessed via ad-hoc wireless with another Android/Inferno device?

- does the windowing system support multiplexing? (e.g. OS-level screen-sharing with another device)

I should post this to the listserv but am too lazy at the moment.
It might be instructive to compare an ORM style API for OLTP style databases vs. OLAP star schemas (http://en.wikipedia.org/wiki/Star_schema). At least, the question of what a conditions API does / mutates in a query may be a very different answer between the two.
The last 2 years I went to Osh Kosh (2006 and 2008) there were two fatalities - one when a visiting pilot crashed on his way in (a lot of people fly in and camp at the air show) and another when two reno air race plans doing a race demo collided on the way in for landing. The sad part about the later crash is that it was a father and son who collided and the son was the one who died.

Works for me, OSX chrome.
I don't see why you'd do this, though. Readers will continue to fall in price and the expense of providing them to the poor is partially offset by using them for textbooks (both that we no longer need to supply them out of "library" budgets and that we reduce textbook costs). It might be possible in major cities to fund readers for the poor out of the liquidation of branch library real estate in favor of wireless access points or whatever.
Interesting, thanks. Do you have a guess on what the Dart means by "Dash is designed with performance characteristics in mind, so that it is possible to create VMs that do not have the performance problems that all EcmaScript VMs must have." Where will a redesign likely see gains?
Thanks, I like Ubuntu Server as well. If it's good enough for Facebook (so I've heard, at least) it's good enough for me.

I currently run Ubuntu desktop 10.04, and several Ubuntu Servers in bridged VirtualBox vm's for development, which lets me simulate a multi-server production environment on my desktop.

However, I've been thinking about switching the desktop to Arch using Xmonad or i3, and KVM for the vm's (keeping Ubuntu Server).

Any experience running KVM on Arch? Assuming there's no issues with it.

PsyD Programs - A Brief Overview
The Cyborg in Us All
For the last 3 years, I was visiting a cooperative university where you work half of the semester as a regular employee of a company and studying the other half of the semester. During the theory semester, I was sleeping between 3 to 4 hours on weekdays, leaving home somewhere around 5:40 in the morning and sometimes arriving at home at 8:00 in the evening, eating, and then hitting the gym for one hour.

As long as I was able to get some sleep on the train commute, I was actually able to cope with that tiny amount of sleep pretty well, I think. Looking back at that time, it might very have been the most productive I had yet.

I felt sooo much better getting up at 4:30 in the morning than I feel now when I get up at 6 or 7 (or even later).
I can only echo this.

I was always staying up late before school, until 12-1 and waking up at around 7 on weekdays. When I got home I almost always took a nap, from half an hour to a full occasionally. On weekends I stayed up late too, but then I slept a lot longer so I got about 10 hours or more.

Now when me and my girlfriend lives together I've been forced to adjust and I often go to sleep at 10, read a bit before sleep and wake up after about 8 hours even on weekends. I feel a lot better now and I wouldn't want to go back to how I had it only a year ago.

I haven't really thought about sleep deprivation but in retrospect it kinda fits.
Yeah, it's a bit silly as I seem to remember it was already doable in old IE before they locked down how you could access parent/child windows and it never failed to annoy.

If anyone can remember the sites that used to have a pop 'remote control' window for video.

I'm also sure my old work used it for wizards.

Something only tangentially related to this, but neat nonetheless, and this seems like a good place to plug it: how to open a kensington lock with a toilet paper tube, some duct tape and a pen. Actually tried this once and it worked.

I think this is a good paper overall, but they're not taking the state of the art as their baseline. They say 5-10 us may be possible in a few years, but <4 us is already on the market: "In TCP testing, server-to-switch-to-server mean latency was as low as 3.6 microseconds." [1] (Perhaps the authors are unaware of OpenOnload because it came from industry.) Complaining that "normal" switches, NICs, and software are behind the state of the art doesn't seem like a topic of research.

Doesn't seem like horrible advice to me. Sure, if someone finds it, you're out your backup key. But unless the thief SAW YOU put it there (and you hid it a block away from your abode as instructed) how is a thief gonna establish the necessary link between the key and the lock it opens? Try it on every lock in the neighborhood? And a backup key costs what, $3-$4, and can be operated by anyone, neither of which are properties of a lockpick set.
Intel's Ivy Bridge Architecture Exposed
I find the author to be looking at ORM the wrong way, the way I see it: ORM just gives you basic features that you would probably write yourself, you still have need SQL for more complex stuff.

Basically it's just a standard way to do the basic stuff.

If you want optimized select queries, you can still write them, also inserts are optimal with ORMs.

I agree completely with you, but I recognize that person's sentiment that challenging kids and allowing them to excel is considered child abuse. This is a viewpoint found pretty much uniquely in the US, and I see it as a fascinating cultural development. The self-esteem movement is the cause. Anything that makes a child cry or even feel uncomfortable is considered de facto evidence of abuse. Also allowing your children to play in the yard unsupervised is child neglect, as are cases where a small child gets up in the middle of the night, unlocks the door and wanders down the street. We've even had parents arrested for this, charged with abuse, and placed in prison in the US. There's a "Free Range Children" movement that counters this thinking with reality checks that a child playing alone outside is not really highly likely to be abducted by pedophiles: according to statistics it's less likely to happen than being struck by lightning (and lightning strikes can happen while playing outside supervised.) Most "abductions" are non-custodial parents. Stranger abductions are extremely rare (a dozen a year) but almost exclusively teen girl kidnappings. Small children are almost never taken. Yes there are exceptions, just as sometimes people get struck by lightning.

Related to this idea of risk comparing the US to Russia I found this video that some Russian kids posted last week fascinating: http://www.youtube.com/watch?v=XjAMdbEXSdo There you will see four school kids, three boys and a girl, wearing street clothes, climb the cable of a fairly tall suspension bridge, while videotaping the whole thing. Meanwhile cars drive by hundreds of feet below. No one calls the police, the kids aren't arrested then placed in state care, the parents aren't arrested and charged with neglect. That's what would happen in the US and people would be on TV denouncing everything about this. Is what they are doing dangerous? Somewhat. The chance of falling is similar to that of playing on the monkey bars, only the potential injuries are clearly more severe. That said, children have died from monkey bar falls. Should climbing suspension cables be advocated or sold as an adventure holiday? I'd say not. I find it very interesting though that in Russia it's not interfered with. The kids choose to do it of their own free will and they are not harming anyone, they are assuming the risk themselves. Let them do it, why not. In the past, Americans accepted more risk, more crying, more stunts. People went to the moon, an intrinsically dangerous task. Russians tried to go to the moon as well. Many died trying. It was considered worth the risk, people took the risks themselves, and if they were hurt that was part of life.
Indeed. I was just thinking I could try it on the device my neighbor has: A very cheap android 2.2 tablet with a resistive screen and pen, no multitouch. Never mind, it can hardly run android apps.

The [Octopus project](http://lsub.org/ls/octopus.html) has an interesting take on gestures. When right-clicking, it pops up a circular menu where the direction one goes in determines the action. See http://lockerz.com/s/139588614 That might be something for touch tablets.

I daily use AcmeSAC on Mac & Win7 with a trackpad (and MagicPrefs for three finger middle click) and with a Wacom tablet and pen. Very nice for editing without RSI problems.
I live with something approximately close.

Having an office to go into and coworkers to be accountable to is the only thing that keeps me sane.
Nanotech can neither replicate nor kill us yet. It's not magic, and evolution has a huge head start on dealing with issues like powering it and self-replication. Devices at that scale are, generally, quite frail to things like stray cosmic rays or other background radiation causing them to break down.

And the space shuttles are dead; there will be no more of them. Horses, meanwhile, have survived for millions of years, so you're making the opposite point by mistake.
> What I really need is an alarm hooked up to a primitive EEG so that it can start the clock when I fall asleep, and set off an alarm after a programmable number of minutes. That way I could sleep for 6 hrs without ever being groggy. But even the cheapest EEG stuff I've seen connectable to a computer is not cheap.

There are various devices for sleep enhancement, e.g. "the sleep watch"[1]. I haven't tested any of them, though (nobody ships stuff to Russia).

Yep, true for me too, unless I self-medicate with nootropics, less than 9 hours don't do it for me.

That's actually my lecture that ClassMetric broke down in the blog post. From a (first time) instructor's perspective, I don't see the tool as a distraction to students. I'm not punishing students for using it, and students have another way to communicate to me that they don't understand something in lecture. I only lectured for one hour a week, the TAs spent the majority of the time with the students. In my case, Class Metric allowed me to touch on the big ideas of the week during my lecture, measure confusion on topics, and figure out how TAs should structure their discussions and labs to be the most useful to the most students. The message posting system also allowed TAs to participate directly during lecture as well, answering questions and addressing confusion as it appeared so students could better keep up with the lecture material. Yes, it may be distracting to have knowledge coming from two channels, but students can still refer back to that channel later when they are reviewing the whole lecture material.

There are three major and important reasons: for retirement, to provide a cushion, and to be able to capitalize on opportunity. If you save more now, you can retire earlier or maintain a higher quality of life. If you save enough to provide a nice cushion, you can ride out the bad times or worse (child sick, lose job, car falls apart...). Again, and perhaps most excitingly, being able to draw on a reserve lets you leverage opportunity.

This is not about debt. It's about making sure you have the ability and the freedom to live beyond the day to day.
Is Teaching MapReduce Healthy For Students?
I can't say I've ever encountered, or even heard of anyone encountering, such a candidate.

The parent post claims that there's some vast, undocumented sea of talented unemployed developers, but I am aware of no statistical documentation of such, and no anecdotes resembling your hypothetical situation. That the parent has a large chip on his shoulder about his age is obvious from his posting history, but in my experience if a dev of any age is having trouble finding work the reason is always that they're not nearly as talented as they think they are. 90% of the people in this industry are just plain bad at what they do.

But let's say it happened: would we give this hypothetical person a fair shake? I'd like to think so. His age is irrelevant. His experience is valuable. But why is COBOL his only listed skill? If that was the only tool at his mainframe job, that's all well and good, but the #1 thing I want to see out of candidates is a lot of evidence that they are keeping up with the industry and keeping their tool chest well stocked with cutting edge tools they're picking up on their own time. I want the people I work with to be autodidacts who can quickly and smoothly move from ruby to clojure to objective-c as a project evolves. 30 years at one tool doesn't scream self-motivated learner to me.

But maybe he could talk me around at the interview.
Keeps crashing my iPhone browser ironically
In 11th grade (1999), I learned how to program in Javascript from http://www.htmlgoodies.com/primers/jsp . I went through every single one of those documents / primers.

As zedshaw says, do every exercise, type every bit of code, etc.

After learning javascript, I went on to learn something more immediately useful. It took me about a month before I had built and completed my own local file search engine with jscript (windows scripting) and ms access. I altered my sleep schedule to 34/14 (awake 34 hours, sleep 14). If your mind is actively engaged in the learning, you won't need to sleep regularly. Sleep was the only limiting factor.

3 months after first learning javascript, I had rewritten my file search engine in perl and C, and upgraded my database from ms access to mysql. I didn't know much about perl and C, but I was happy to now "know" 3 languages and 2 databases.
JS has notorious optimization hazards such as holes in arrays (Array.prototype[1] = "ha ha"; a = [0,,2]; ... a[i] for i=1 must find the prototype element), prototype delegation in general, delete and default-mutability, plus the eval of old and 'with' (respectively reformed in modern impls and specs, and banned in strict mode).

These all add some cost in either runtime guards, static analysis burdens, or a mix.

A new language could leave out most of these, but it would still want inheritance. Then the question would be: how useful is mutability along the inheritance chain, i.e. shadowing -- even if you remove 'delete'.

Beyond this, a new language or a JS extension (this is what the Dash memo rules out as un-possible, without evidence) could allow pinning down the shape of objects, even to include machine types such as int32, etc. That would allow for big speedups on certain benchmarks.
I'm having the same problem.

> Try it on every lock in the neighborhood?

Yup, quite possibly. The return/effort ratio for doing that is pretty good. The thief doesn't need to get in the same day as s/he finds the key, after all.

In which case, although you may not be a sockpuppet in the literal sense, what you did is frankly not much better. Sorry to be the bearer of disagreeable news, but that's how it is.

It's not just that you'll get downvotes for this. I don't know about anyone else, but my opinion of the likely value of ClassMetrics went down when I saw your comment, and further down when it was confirmed that you were indeed basically spamming HN. That's probably not the outcome you were looking for.

[EDITED to fix a typo.]
So long as you understand "under the doormat" and "in the flowerpot" are not Clever Hiding Places, you can probably come up with some pretty good spots.

You can take advantage of logistics as well; for example, hide the key somewhere in/on your car. A potential thief would need to steal your key in advance, lest the key simply be gone when ever you're gone.

Ask HN: Hosting Django: Heroku, Gondor, or myself?
Hi,

I'm a web-developer, I love working with a django stack (django/postgres/south/redis/celery/etc), and I've deployed apps myself on ec2 or hosted on dotcloud.

I'd like to be able to iterate through some product ideas so I'm very price-conscious. Ideally I don't want to be charged 10x for hosting 10 web-apps, I want to be charged by traffic. For example if 1 app gets sticky and 9 suck, I shouldn't be charged much more than if I had 1 good app and 1 bad one.

Hosting on EC2 or Linode seems great for this, but I'm actually not super-comfortable with the sysadmin side of things, so I'd prefer to use a Heroku/Gondor or something similar.

Does anyone have any suggestions?

Thanks!
I doubt the 'tip of the spear' will consist of fleets of large, slow airships. The strategic value in lighter-than-air craft is in their ability to stay airborne for extended periods with relatively little control, and access areas unavailable to traditional aircraft.

Of course, these airships will likely not be able to the perform 'combat landings' to the extent the C130s can.
True. This is actually the v2 of the landing page, and I forgot to add that in.

Basically, I e-mail myself notes all the time. I know there are many note-taking apps out there, but I never end up using them efficiently because they force me to create a new habit.

cc:to me takes advantage of my pre-existing e-mail addiction to make notes fit into my routine.

Also because e-mail clients support html, I can send myself snips of a website with simple drag and drop.
Why should anyone should be allowed to arbitrarily use an institution's name as though they sponsored a publication, event, organization, etc?

I implemented a lot of statistics functions to learn how to program in a language. Some of the things I've learned on include:

* moving averages
* linear regression
* matrix operations
* matrix lu factorization
* polynomial interpolation.
* multiple linear regression
* cubic spline interpolation
* variance, covariance, correlation
* gamma function
* t-test, t-value calculations

One limitation of the above is that it doesn't explore all of a language's features. The above are mostly interested in array processing. There aren't any classes or generic types or what-have-you.

Grit Test

Yea, just come up with something that can be grouped to be among your favorites or something that simply makes for interesting conversation.
Love it - I find myself emailing myself notes and links several times a day, and this is a big time saver.

Two suggestions:

1) make a Chrome and FF browser extension for it, so you can get a first-class button on the browser (or be in the right-click menu). Bookmarklets are quick and easy, but I don't display my bookmarks bar in Chrome, so I have to go hunt for it. By contrast, my Bit.ly chrome extension has a cute little yellow fish button at the top of my browser all the time, and so gets mindshare and use every day.

2) The notes are sent without a subject line. Would recommend a subject something like "[cctome] First 30 or so characters of note..."
This metric seems to be just as flawed as total bitcoins transferred. Why should a bitcoin that hasn't been spend in a while be worth more than one that was spent yesterday? If someone sells something for bitcoins and then buys something else the same day, that seems like a great indicator of bitcoin activity but the second transaction is completely ignored by this metric.
