Comment She never saw the computer? (Score 1) 94

That's about the silliest thing I've heard today. A television screen, even in 1984, was probably a computer monitor. Granted it was NTSC, but around that time most televisions were switched over to digital tuners (which are computers).

I mean, I'm a computer programmer, and I spend my day working in Visual Studio, vim, and NetBeans (depending on what I'm doing). By that logic, I never see a computer either, at least not the one I'm working on. I spend most of my day in an RDP session on a retired tradeshow 27" iMac. I have to touch xcode once in a while, but I mostly keep it for the real estate.

Comment quite a few browsers? (Score 5, Insightful) 246

Animated PNG support is terrible... see:

No IE, no Chrome, Opera dropped it when they went to Webkit, no iPhone, no Android...
looks like it's pretty much only available on 20%ish of desktop browsers and pretty much nothing mobile. You aren't going to get anyone to use it in a public-facing web application yet. Remember the days of "this site looks best in (Internet Explorer/Netscape/whatever)"... let's not do that again.

Maybe if the HTML 5 standard said that conforming user agents have to do this it would put a little more umph behind it. Of course, the standard seems to follow browser development in many cases now, not the other way around.

Comment I don't (Score 1) 329

I'm a QA analyst for a software company. My workplace is saturated with WiFi. My wife has a cheap-but-has-everything-she-wants HTC One V (Android ICS) with prepaid Virgin Moble. I live 0.75 miles from my home, which is also saturated with WiFi. I get by on just an iPod Touch 4, with vTok for calls between me and my wife. We have $7/mo voip service at home for a pseudo-landline, but I bet I could put a client on the iPod if I wanted to.

Comment Cost Benefit (Score 4, Informative) 736

Progress bars do not make sequences of actions complete any faster. In fact, they make them slower.

That being said, take for example an installer that must perform the following steps during an upgrade:

0. Figure out how many files need to be replaced.
1. Replace 30 files of varying sizes.
2. Add 10 files.
3. Update a half million rows inn a table with a million rows setting a column to a computed value based on some predicates.
4. Run a third party installation mechanism (MSM?) for a supporting library, etc.

Modern computers are time-sharing systems. Each process that involves computation is at the mercy of the scheduler in the kernel to give it the cycles it needs to complete. That means that even if you measure the time it takes to complete some process, it's not going to be the same a second time, because the installation process doesn't get undivided attention.

Steps 0 - 2 - you're at the mercy of the IO buses, hard disk, antivirus software interfering, etc.
Step 3 - What shape are the database statistics in? How efficiently can you apply the predicates? What does the distribution of the data look like? You can't tell this ahead of time...
Step 4 - Does this third party installer provide you some sort of metrics as it runs?

These are the sorts of problems to be overcome to do an accurate progress bar. In short, they aren't worth overcoming.

Comment Solemnity of Mary, Mother of God (Score 2) 157

I celebrate the new year by attending Mass for the Solemnity of Mary, Mother of God.

This isn't really "Good-old Gregorian January 1st". When Gregory XIII introduced the new calendar in the 16th century, new year's day was the Feast of the Circumcision of Christ, and that's the way the calendar was until the liturgical reforms of the Second Vatican Ecumenical Council restored the Solemnity of Mary, Mother of God to the 1st, which is when it had been celebrated in ancient times since the early councils established the dogma of Theotokos.

So, I think I'd rather say I celebrate the New-Fangled Gregorian January 1st.

Comment My e-reader killed its own market (Score 1) 333

I have an iPad2, which I use for all indoor reading with the Kindle and Bluefire apps. I also had, before the iPad2, a Sony PRS-300 and I still use it for outdoor reading. The iPad2 is already bordering obsolete, but the Sony still does what I want. It's only function is e-reading, and I just don't see how, except the battery being too expensive to replace, I would justify replacing it in the next couple years. When we get something like a piece of paper (a killer form factor) for e-readers, I will replace it.

I guess what I'm saying is that the market is declining because people already have them.

Comment Andi Graph (Score 1) 254

For that TI-8x look and feel...

I use Andi Graph. http://dougmelton.com/android/andie-graph/ . It's free if you already own a TI calculator. If you don't, you are morally obligated to purchase a TI calculator so that you can say you've paid for the software. It is exactly like using a real TI-8x calculator except the buttons are not tactile.

It runs faster than a real TI-8x on an HTC One V phone, which is a low-end ICS phone. If you want to run it on a PC, get the Android emulator from Google.

If you don't have your cable to rip the ROM from your calculator, you can find the ROM using Google. I don't think there is a version for iOS.

There are TI-83/83+/85/86 emulators for Android. You just load a TI ROM into them and you're done. Having tried it, here are the biggest problems:

1. Battery life sucks.
2. The touchscreen is a lousy keypad for a calc with that many buttons.

I know that many profs won't allow these devices during tests because of the potential for communicating with other people using them during the tests.

Apple will never allow these emulators on iDevices. They don't like people running arbitrary code in the walled garden. zShell anyone?

Moon

A Supercomputer On the Moon To Direct Deep Space Traffic 166

Hugh Pickens writes "NASA currently controls its deep space missions through a network of 13 giant antennas in California, Spain and Australia known as the Deep Space Network (DSN) but the network is obsolete and just not up to the job of transmitting the growing workload of extra-terrestrial data from deep space missions. That's why Ouliang Chang has proposed building a massive supercomputer in a deep dark crater on the side of the moon facing away from Earth and all of its electromagnetic chatter. Nuclear-powered, it would accept signals from space, store them, process them if needed and then relay the data back to Earth as time and bandwidth allows. The supercomputer would run in frigid regions near one of the moon's poles where cold temperatures would make cooling the supercomputer easier, and would communicate with spaceships and earth using a system of inflatable, steerable antennas that would hang suspended over moon craters, giving the Deep Space Network a second focal point away from earth. As well as boosting humanity's space-borne communication abilities, Chang's presentation at a space conference (PDF) in Pasadena, California also suggests that the moon-based dishes could work in unison with those on Earth to perform very-long-baseline interferometry, which allows multiple telescopes to be combined to emulate one huge telescope. Best of all the project has the potential to excite the imagination of future spacegoers and get men back on the moon."
