I'm one of the TAs (section leaders) for 106X this quarter. We get a pretty wide diversity of skill levels in the class, so it's tough to ensure that we challenge the experienced students while not scaring off everyone else.

However, the goal of 106X isn't to teach all of the complexities and nuances of algorithms (take CS161), fundamental principles of computing (take 103), or OS/low level understanding (take 107/140/143). Sure, we'd like students to think about these things, but we really want to make sure that students know how to program with

* Proper decomposition

* Sensible commenting/documentation

* Use of appropriate data structures/knowing when to employ recursion

If you want to get more "huh, that's cool", try taking 107 in the winter (Jerry is teaching that course as well).
IANAL but trying to read the law, it seems to be a rather blatant lex google.[1] They specifically state "search engine or similar services" should be prohibited from (in an extreme interpretation) linking to newspapers, if they do not pay. ( The rest of the law is probably just redundant, since it seems to reimplement copyright for a small subset of already copyrighted material.)

Isn't that always the case with mitochondria, since they only come from the mother?

Book Review - Implementing Responsive Design
Since Germany is a populous and wealthy country, Google has a strong commercial interest in not removing German content. It's hard to imagine what nefarious thing Google would force Germany to do this way.
Evidence is he is a raging "bath salt" addict. These are common symptoms. They will get worse for awhile if he de-toxes.
Wasn't that turned upside down by the Toyota way of doing it? I remember hearing an episode of This American Life about it. The difference being that it saves more money to fix the problem right the first time then continue the line rather than continuing the line at all cost and fixing later.

I believe it was http://www.thisamericanlife.org/radio-archives/episode/403/n... where they interviewed people involved with it.
Any insights you can share? I'm looking at this now, and it's not encouraging compared to dedicated hardware.

I think it's a simple mis-labelling. Zune's and Google's slices are reversed. Note that there are two '3%' segments, they just don't match the labels.

That said, it is quite sloppy.

I can sincerely believe these are crimes against humanity, and still be right. What I believe to be crimes against humanity is not going to affect xss in any way.

By your analogy, if Hitler says exercising is good, you will respond "why would you consider his opinion in the first place".

How not to "update" an iOS app
Well, you have something like 21 electrodes wound around the hearing nerve. Of those, usually four or so do not work. The rest is all you have available. Simplistically said, you can encode only 17 distinct frequencies.

There are some more intricacies involved, but the general message holds: Frequency resolution is severely impaired. Time resolution and loudness levels are diminished, too. In fact, many CI patients can not percieve music any more.

Funny enough though, they can usually enjoy music they knew from "before".

Still, it is a wonder of modern medicine to give hearing to people with nothing more than a working hearing nerve. CIs are true nerve-computer interfaces.
Not awfully surprising. It's a toy, not a Predator. Security likely was not a major design concern, and I don't really blame them. Probably even intentional to a degree, to make (owner-sourced) hacking easier.
The Inevitability of the Cloud
Mh, if I understand correctly the messaging system being tested is https://github.com/derekcollison/nats and it is not written in Go but in Ruby (+EventMachine). Or is there a Go version of NATS?

Also, this is only testing the time it takes the go client to write the messages to the socket, not the time the server takes to process the messages. So the benchmark would be the same with a noop server that reads and discards all incoming traffic. Am I wrong?
>..every year is something consumers want...

Consumers were pretty happy with PalmOS & Motorola Q until the iPhone came out. We, however, the populace of geeks who inhabit HN, should know better. There are many ways in which Android is pulling away from iOS. From automatic app updates, to account registration & syncing..to widgets & lockscreens. None of these are a fatal blow but all taken together start adding up to a significant advantage.

On the other hand, iOS smoothness & polish are still second to none. I'm not saying it's a bad mobile os at all. It's an amazing piece of software. I'm saying I wish it were evolving.. faster. Just look at the amazing update iTunes just received. Compared to the previous version, It's an order of magnitude faster on my laptop. I was hoping for a similar leap from iOS5 to 6. It didn't materialize.

Recently, I saw an Article on The Verge taking on the static weather app icon that hasn't changed since 2007 & how it's a metaphor for Apple's being overly careful & protective (or lazy, take your pick) of the UI it introduced with the first iPhone. I think that's valid criticism.

Full Disclosure : I carry two devices with me all the time. an iPhone 5 (iOS 6.1, beta 3) & a Galaxy Nexus (4.2.1) I've had every single iPhone since day 1, Every single iPad except for the 4 & the mini. i'm typing this comment on Macbook air.

T-Mobile CEO confirms the iPhone and the death of phone subsidies
My friend has a daughter who was born deaf and then she and her husband decided to implant her. It was a really hard decision but she was 4 and still not walking due to balance problems and because she didn't hear her surroundings. Well the decision payed off. She is 5 right now and she is walking and running and she started talking a few baby words, so the doctors are pretty sure she will be talking soon. I have been around in her life for about 4 years and I must say that since she got the implant she became a much much happier child.

What do you mean by better? More profitable? That's blatantly false given the financial industry. More honest? That's just tautological.

> Recently, two big news newspapers had to shut down and that print sales are declining is nothing new. I cant remember the last time I bought a newspaper and I am also pretty sure that although blogs/twitter/whatever are a good addition they cant replace classical media. There is definately a need for the discussion for new sources of incomes for classical paper based medias as ad sales from their online publication wont cut it.

... I like Clay Shirky's comment:

> Round and round this goes, with the people committed to saving newspapers demanding to know “If the old model is broken, what will work in its place?” To which the answer is: Nothing. Nothing will work. There is no general model for newspapers to replace the one the internet just broke.

and

The newspaper people often note that newspapers benefit society as a whole. This is true, but irrelevant to the problem at hand; “You’re gonna miss us when we’re gone!” has never been much of a business model.

I am not the author of the gist but quoting from it: "our work on a high performance NATS server in Go." Furthermore, the tests he shows are run using Go's testing tool (which tests go code). Finally, he discusses "no use of defer" a Go language feature not in Ruby. So yes I believe it is an implementation in Go.
This topic is covered in the Isaacson biography; Isaacson's recounting doesn't paint Jobs so black-and-white on the issue. the excerpt:

Jobs went on to urge that a way be found to train more American engineers. Apple had 700,000 factory workers employed in China, he said, and that was because it needed 30,000 engineers on-site to support those workers. “You can’t find that many in America to hire,” he said. These factory engineers did not have to be PhDs or geniuses; they simply needed to have basic engineering skills for manufacturing. Tech schools, community colleges, or trade schools could train them. “If you could educate these engineers,” he said, “we could move more manufacturing plants here.” The argument made a strong impression on the president. Two or three times over the next month he told his aides, “We’ve got to find ways to train those 30,000 manufacturing engineers that Jobs told us about.”

Hmm, you cannot make 2M read/write syscalls a sec. So what's the definition of a message here and through what transport medium does it go through?
Surely the combination of research and smart designers is better than either in isolation, though, right? Do you have evidence that the designers of the ribbon were not "smart"? Are you aware of a better design for surfacing hundreds of features? Clearly, standard menu bars weren't working. The combination of the ribbon plus the quick access toolbar seems quite elegant to me...

“To whom much is given, much is expected.” is an exciting quote to see Tim Cook get passionate about. Having an 11-digit cash hoard at your disposal could be an unbelievable force for good.

For your first question: maybe, there is "s = startServer(b, PERF_PORT, "")" in the code, but this could easily be an external call.
T-Mobile Finally Gets the Apple iPhone
I switched to Windows 8 last night. I added a start button to the interface like a lot of people. That aside, I really like the use of tiles for quick access to evernote and certain information.

Overall I would really enjoy the interface if I had a touch screen. In a sense it's a little too 'user friendly' which isn't as good for us technical people

This particular ford plant gets engines Just In Time from the foundry ~100km away, using a highway that has frequent traffic jams.

It was found that when a truck load of engines was late, the most cost effective thing to do was to crush the brand new engine-less cars, and crush the engines when they arrived rather than either stop the line, or try to shuffle the cars & engines in at a later time. It was mind-boggling, but the numbers were run many times in many different ways and it was true.
Check out 'Touchpal'. I've been using that instead.
The code sample suggests it's a network interface at localhost, but it's not 2M syscalls or connections. It's just one big buffered write and it doesn't look like they're waiting for responses to those messages - so essentially this might just be a (pretty good?) stream processing app.

That makes no sense. First, he's advocating private ownership of electrical infrastructure, not the elimination of it. Built by private interests doesn't equate to non-existence.

In case you collect logical fallacies, this is a wonderful example of "Argument from adverse consequences":

A

But A leads to B, and B is bad

Therefore, Not A

This is reasonable if you're deciding whether to pursue A as a course of action, but it is idiotic if you're trying to decide whether A is true or not. A will be true or false regardless of whether you like what it leads to.
Well said. Although I think part of the article is saying that as people, we shouldn't be afraid of stepping outside of our comfort zones to try something new, even if on the surface it doesn't immediately look like it's gonna be "greener pasture".

I think another thing to remember is that no matter how hard we try, it's not really possible to guarantee that our lives will always be "improving". Somewhere sometime we would all be better off learning to take the good with the bad - this will free us up to experiment and try new things without being completely reckless. As a result, I believe we'll all live more fulfilling lives.
Sorry, I need to correct that. I meant that shards are basically still primary / secondary with an arbiter for failover. We prefer horizontal nodes instead, like Cloudant, Elastic Search or Cassandra offers.

I don't think it's fair to attribute all of the recent Apple products to Cook. Most of those products, if not all, were probably well into the design and/or testing phase by the time Cook took over. In another 12-18 months, I think we can then start analyzing products to find Cook's DNA in them. At minimum, I'd say that the 2014 iPhone, iPad and Mac lines will be a much more accurate representation of Cook's product leadership.
Mathematical Formula For a Perfectly Decorated Christmas Tree

Outlook is probably one of the most complicated non-admin pieces of software that Windows users use, and I find it completely impossible to do real things in 2010 - in fact, it took me way longer than it should have to even figure out that I was running Outlook 2010.

There are conventions to any interface. In Windows, Help -> About will tell you what version of a piece of software you're using most of the time, but for some reason Outlook feels that I need to go to File -> Help -> Additional Version and Copyright Information.

Disregarding decades of convention because a handful of wankers with a whiteboard say so is a recipe for failure. I find LibreOffice far easier to use than newer versions of Microsoft Office precisely because their navigation isn't a convoluted wad of deuce.

There is a reason that Visual Studio, Visio, and Project don't have the ribbon interface - it's not better for anyone who actually knows how to use a computer. The ribbon interface was designed for a mythical group of people that hadn't ever used Windows-style context menus in 2005. Maybe as an emergent, intuitive interface for people who've never sent an email, the ribbon is great, but it's different than any other piece of software out there, and I've never met anyone who actually prefers it.
