If you have no haptic feedback and dynamically shifting context-sensitive layouts, touch-typing is very hard. You simply won't be able to achieve the efficiency of a scientific calculator like the HP 15C or 32S, and even approaching the usability of a graphing calculator for the simpler operations will be hard.

The potential usability gains for more complicated operations might be worth it for higher-level classes (and a good port of Geometer's Sketchpad would be invaluable), but I don't think it would help for a typical homework problem set unless it also had a good way to help you typeset the solutions you computed.

TL;DR: Mobile platforms can bring (Internet) technology to a global audience that is larger than any that we have seen. Smartphones represent a very small percentage of this audience, so there is more money in creating services that work on all mobile platforms, utilizing SMS/MMS.

Fukushima: What happened - and what needs to be done
Anecdotally, I've only actually been driven to piracy by DRM once. I bought "The Great Adventure Bundle 2010" from Telltale games, and one of the included games had a weird conflict between its DRM and something about many people's systems that rendered it unplayable. So I downloaded a cracked .exe and was able to play the game I had paid for.

Definitely feels wrong when the pirates get to have the better user experience.
I'm sure your father was saying the same thing forty years ago.
Most managers I know would love to have the ability to prune and rehire staff to rebalance teams and optimise skills, enthusiasm etc. However in many cases (particularly in big companies), managers have very little say in their headcount numbers - most of it being controlled by HR who in turn are watching the bottom line.

As a result, HR can often make it extremely difficult, if not impossible, to hire backfills or additional staff and hence managers quickly learn that it is better to retain a 60% effective person than have no-one at all.

This lesson is even further reinforced when managers are forced to sack staff to hit some corporate cost take-out target which means they have to cut staff regardless of the teams actual resource needs and without the 'low performers' in the team, you would have to cut the good performers.

It's a sad state of affairs, but one I've seen on so many occasions.
It's looked exactly like this at least since I last looked at it last week.

I think you're missing the point. Steve Jobs had a choice of 1000 things to focus on when making a computer and OS. You can't focus on everything, due to time and (brain) memory restraints.

So, because he took those classes, he was convinced to focus on typography as an important element to the OS. If he hadn't, it isn't as likely he'd have been illuminated to the benefits of good typography.

That is, unless you believe in some sort of determinism, where he was bound to fall in love with typography at some point.

Say what you want about the price, but the HP-12c remains one of the most useful and nicest pieces of hardware I have ever had the pleasure of owning.

That thing will last a lifetime too, they're tanks.
The idea is great but unfortunately the technology behind it is limiting. Since their highest pricing plan only allows for 10 simultaneous viewers it's not realistic option to embed it in a popular blog as a demo.
"Not everyone can learn though rote memorization. People learn in different ways."

That doesn't mean that current mathematics teaching methods take that in to account. Try looking in a current middle-school or high-school math textbook. I think you'll be surprised, and disappointed.

When I was learning high-school level math, I found that the quality and usefulness of a math textbook was inversely proportional to the probability of the public schools using it (and, perhaps not too coincidentally, the colorfulness of the textbook).

In recent years, my local schools tried to get away from a rote curriculum by replacing it with a curriculum that basically eschewed teaching, instead relying on "guided discovery" or something like that. It didn't help the standardized test scores or the students' mastery of what they were supposed to learn.
I know someone who did this same type of thing in Panama, except even the corporation can't be majority controlled by foreigners. So the Board of Directors of the proxy corporation is a bunch of locals who are paid to essentially quit at the behest of the foreign owner.

Actually using append only writing is very helpful for SSD drives. Overwriting a particular piece of data is very tricky for flash drives.

In fact, underneath the hood, flash drives use append only even when you are trying to overwrite something. For example, if you want to overwrite a byte at location X, the flash drive actually writes the new data at a different location Y and uses logical mapping to have the byte at location Y pretend it is the byte at location X. The initial byte at location X will eventually be "recycled" and initialized.

Since Flash does append only writing under the hood anyways, it is a better idea to do append only explicitly so that you get the advantages of append only (e.g., the ability to revert to older versions).
Loud, cold/hot. With the trends to making PUE count it can get quite uncomfortable in a hot aisle. The inefficient ones are more sweater territory...
Suppose, for example, an employee negotiates a package with a company, and part of that negotiation is for a stock package that the company estimates is worth X. Now, it seems to me that the estimate has to be a good-faith estimate in order for the negotiation to be valid.

That's where you have gone wrong. No private company (unless they are insane) will ever state a future value for a stock package - they will merely offer units of stock (and maybe state it in terms of a percentage of the company). The employee might try and calculate that value, and the company might state things like "based on our last funding valuation these shares are valued at $X", but that is very different to claiming they will be worth anything at any date in the future.

In startup companies, share options are usually granted using a vesting arrangement, which assigns a low value to the share options but doesn't allow
the employee to buy them until some point in the future (where presumably the share will be worth more than the option). If that point arrives, and the shares are worth less than the options then bad luck! (This situation isn't uncommon, and is known as "being underwater". It occurs in public companies, too. For example, Google revalued the options of its employees in 2008 after the Google share price fell substantially and a majority of its employees were underwater)

The situation is different for publicly listed companies of course, because there the stock actually is worth something. In that case the company really can give a value to the shares at that point in time.
That holds if you're a dynamic startup. Most of the money, and certainly most of the money to be conserved by avoiding taxes, isn't going through dynamic startups.
Is it notable, though? Serious question.

I mean, Twisted and Tornado have actual references. (Eventmachine does not, but whatever.)

Node currently has two, one of which is a linkbait-y post on readwriteweb, the other is an extremely meager wiki template page. Ergo, it isn't notable.

That looks interesting, but at least for the near future solutions like that aren't good for things you want other people to run without having to do a lot of work. That said, I'll definitely look into using that as I learn Clojure.
The potential for data/program corruption is much higher when it is closing down (think of what happens when the computer shuts down, or when the program is closed immediately followed by a shutdown. )
I'm not encouraging what I listed above. Quite the contrary, I find it to be awful. I don't learn through memorization. I learn programming well, chemistry well, math well. I can't remember or "learn" history for the life of me. At best, I might retain major concepts if I can relate them to me very personally, but even then it's usually very vague.

My comment was meant as critical not as praise for the current system. I think it's horribly ineffective as you note
Do you still see 3D with one eye closed?

Most people instinctively say "no". But the reality is that there are far more cues for depth than just stereoscopic vision. Someone with one eye still perceives depths by judging relative object sizes, changes in focus and subtle changes in objects when we move relative to the object.

Head tracking will almost certainly play a big part in coming 3D techs (with or without stereoscopic tech). Add to this eye tracking to adjust virtual focus, and you start to get "real" 3D. One day!
Sounds like someone isn't testing their code. "one would need to write tests to catch in ruby". You're damn right you need to write tests to catch problems in Ruby, as you should probably be doing anyways - in any language - in which case confidence gained from your test suite is almost entirely redundant to the confidence gained from successful compilation in a static language.

But if you're not testing your code, then the compiler is indeed a great dose of confidence.

I do, though, firmly agree with this:
"I wouldn't argue against the notion that ruby's expressiveness and use of functional paradigms might make up for it's lack of static typing, and ruby in the hands of a great programmer is pure pleasure, but most teams don't have just great programmers."

Ultimately things do depend quite a bit on the developer resources you have.
So you have to constantly move your head to have some 3D illusion, otherwise if you not moving your head it's just plain 2D. It would be more interesting to combine with stereoscopic 3D, but even with this we are still far from real 3D.

Unfortunately, you do have to replace the batteries every few years, so they're not perfect.

Very few. But I can easily imagine that a lot of the retired military test pilots and retired astronauts out there would be very happy to take this job. And it's not like they need to hire many... they could probably get away with three (one to fly White Knight, one to fly Spaceship Two, and one spare).
Okay, this was all in my undergrad computer architecture course from about 7 years ago. Of course we used a book co-authored by Patterson, so maybe that's why.
I carry a $20 Casio that's light and small enough to go unnoticed in my bag, while providing better tactile response than a smartphone calculator. For anything more substantial I break out MATLAB.

The problem with graphing calculators is that they're autistic. With MATLAB it's trivial to load a data file, run some calculations, generate plots, and export to PDF for use in a document. Graphing calculators are fine for working through problem sets in high school, but outside school they fall in an awkward gap between being too big and heavy to carry around and too limited for real work.

Johnny Lee's version was definitely cool, but it was more of a clever hack. It took advantage of the fact that the Wiimote is basically a very cheap IR camera, which normally tracks the IR light coming from the sensor bar. By using the Wiimote as a stationary camera, and wearing infrared LEDs on his face (attached to safety goggles, iirc) he could track the position of user's head. I'd imagine the Wii hardware would definitely be up to that task, as it is basically just the inverse of what it does already.

Also, if you really want to be impressed with the iPad's rendering capabilities, check out Infinity Blade. That will blow your mind.

Step 0: Practice public speaking

The single best way to become a "kick-ass" public speaker is to speak in public more often. Deliberate practice.

All the tips in the world won't help if you don't get up in front of an audience and practice just that: being in front of an audience and speaking to them.

How can you do this? Toastmasters (http://www.toastmasters.org/) is a fantastic group to join and is available all over the world. I swear by it and so do my friends who have also joined (I went from a nervous public speaker who dreaded the thought of public speaking to a nervous public speaker who _loves_ getting in front of an audience).
This sounds, in many ways, very similar to the data structure underlying Google's Bigtable (http://labs.google.com/papers/bigtable.html) and its descendants. Multi-version key/value store, data organized into a hierarchy of generations, each generation stored in large linear chunks, Bloom filters to minimize the number of generations consulted for a single-key fetch... it would be interesting to see a direct comparison, too bad the authors didn't mention Bigtable in their analysis of previous work.

I also wish the paper spelled out the data structures and algorithms in more detail. I did a little searching but couldn't find more information anywhere. Has anyone found a more complete writeup?
There is a second really important reason to blog, if you write software (and are any good at it). Blogging is a great way to improve your writing and the more senior you become the more you will find that your challenge is not just grokking things yourself but helping other people grok them. Almost all of the really stellar software engineers I worked with, like the senior people at Google, were excellent writers and constantly working hard to improve their writing.

A side note, if English is your second language don't despair. It's easier to rise above the mean than you think and all the good native speakers have achieved their skills by working really hard on it. You might not have enough lifespan to hit the literary top but more than enough to become a really efficient communicator.
Argh, and I was contemplating applying for a product manager role at google. After reading this i wont be applying anytime soon -it's been over 10 years since I studied data structures and algorithms.

Sure, especially if you nest the sets using a datatype indexable with an R-Tree index: http://explainextended.com/2009/09/29/adjacency-list-vs-nest...

However, nested sets is still very expensive to update which may be a deciding factor if your hierarchy is subject to frequent change (like, a folder-like structure with the folders being moved here and there) and you don't need to query for "all descendants" often.

An absolutely necessary feature for me is auto-discovery. Zabbix really has this down with recent versions. If your system has comparable templating/groups and the ability to autodiscover in IP ranges you'd be +1 on most solutions. If you then added better dashboards (ala Zenoss?) and the ability to acknowledge events from emails etc then you'd really have something I'd try out.

Here's the bar for me: If I spend a few solid days on zabbix per "server class" (ie: mysql, web server, etc) I can have everything I need automatically monitored with zero effort for me going forward (to ~1000 servers). That said, acknowledgement of alerts, etc is a huge pain in zabbix.

Inspiration vs. Working Hard: Why Working Hard Always Wins
In aggregate, sure.

Quickly flicking through my analytics reports, I'm seeing IE percentages ranging from 84% (on an investment management site) down to 11% (a designer furniture site).

It wouldn't surprise me at all to see a youth oriented and/or computer gaming oriented site even further skewed away from IE than my furthest outlier.
Human language tends to be arbitrary, and I believe that the opposite (specificity) is desirable in programming languages. Many people argue that the future of programming will involve dumbing things down as more and more people become programmers, and one way of dumbing things down is to use natural language. (I shudder at involuntary thoughts of COBOL.) Instead of dumbing languages down, I think it would be much more beneficial to raise the intelligence of the programmers. I hope that the future of programming languages tends toward mathematics, not human language.

Currently, I am often very happy with Haskell syntax for solving problems, when it is possible to define an implementation that is precise, concise, and easy to understand. For solving problems that do not easily map to Haskell syntax, using DSLs (Domain Specific Languages) to map from a representation designed for the problem in question to a Haskell representation still allows Haskell to be a good choice of language.
