Comment WIFI + tethering (Score 1) 395

It hasn't failed me yet, and has the additional advantage of providing a sort of upgradability that's sorely lacking from most devices these days. I can swap out my carrier, or my cellular technology, without having to buy a whole new tablet. I just wish the rest of the components were as easily upgradable.

Comment I just went through this process (Score 1) 328

Not because I wanted to buy Android instead of a dedicated GPS, but because I've already got four Android phones in the house and didn't want to buy anything.

In my case, I'm going back-packing for 5 days; we have paper maps and compasses, but I want to bring my phone along and see how it does. I have a small, portable solar charger that I'm bringing as well. Here's what I've discovered:

First, I'm taking my Nexus One. I have to take the phone with me anyway; I just won't leave it in the car when we hit the trail. With the screen off most of the time, but with the GPS on and a tracking application running, I got about 7 hours of continuous running before the battery hit critical. All wireless was off; theoretically, the only things running during that time were the CPU and the GPS chip. I used the display for maybe 20 minutes during that whole time. I expect that, with some coddling, this amount of time would be serviceable -- and it'd certainly be a fair emergency device.

The Nexus One compass -- the magnetic one -- is way accurate! I walked around a bunch with a Suunto Global magnetic compass, and the Nexus kept up admirably!

I think I tried every free or demo GPS map program in the market, and the one I settled on was OruxMaps. RMaps and Maveric are interesting and have useful features, but OruxMaps turned out to be the easiest to build up maps of my destination with, and it provided all of the basic features that I wanted. It has a built-in map builder which takes a little fiddling to figure out, but is pretty easy to use once you do. I did this all over Wifi (which is going to be faster than cell data, anyway), so no cell plan is required (although a WAP and internet access still is).

The display is the biggest battery drain, obviously. With that on constantly, you're not going to get more than an hour of battery out of it. However, the Nexus is smaller than any GPS with a color screen that I've seen; attach enough external battery pack (through USB cable) to make it as big as your average Garmin, and I think the battery life would be comparable. As others have said, the quickest and easiest thing to do is just buy a dedicated GPS; you'll get less for your money, but if that's all he wants to use it for, I don't think it's worth the extra effort to set an Android device up as a dedicated GPS.

Comment Re:Swype. (Score 1) 161

Ditto. Actually, I was using ShapeWriter until Swype came out... they both have their nice points, but both of them are nice, and a lot of the time, I actually prefer them to hard keyboards.

ShapeWriter has a really clever capitalization mechanism that I miss in Swype. Often. Swype has slightly better matching. ShapeWriter will insert a space between a period and the next word; Swype doesn't (grrr!). ShapeWriter has an annoying feature where, if the text entry ends with punctuation, the editing of misspelled words doesn't work. Swype requires you to actually swipe over apostrophes to get them (it doesn't recognize "its" as potentially being "it's"). They both have "alternate" keyboards, but ShapeWriter's alternate is much more useful (bigger keys, focused on numeric entry) -- although, both make getting to some common keys (:, /) uncommonly difficult. For some reason, I find Swype much easier to use if I'm tap-typing -- and ShapeWriter is almost impossible to use for password entry (if you're like me and use mixed-case passwords), whereas Swype is useful.

They're both good. I don't know about Swype, but I get regular updates from ShapeWriter. I've been using Swype for the past couple of weeks; I think it annoys me less, but they're pretty darned close.

Comment Nice troll story! (Score 1) 836

It doesn't get any better than that. But feeding the trolls is fun!

I don't know about other people with 4 year CS degrees, but I took three years of calculus (in addition to numerous other math classes); is the poster suggesting that either vocational schools cram four years of math into a two year program, or that math isn't an important part of computer science? Probably the latter. Which would explain a lot of things I've seen in industry over the years, actually.

Comment SSD For Great Love (Score 1) 467

I've been running a Transcend 64GB SSD (ca. $200, PATA -- not high-end, definitely) in my laptop for 10 months. It's on all the time, except when I suspend it for transportation. It is running Ubuntu, and I've got a current uptime of 30 days. I'm a software developer; I download and install betas of OpenOffice, I upgrade Netbeans and Eclipse regularly, update and build software (including one work project that's over 1GB built), and generally trash the hard drive. I haven't had any trouble with it, at all.

I also installed an OCZ 64GB SATA SSD in my wife's laptop since mid-June (so, 4.5 months). Hers is more often in sleep mode than in use, since she has a separate, work, laptop. She uses it for writing, homework, browsing, and so on -- light duty. No problems there, either.

Neither laptop is configured to run /var/log or /tmp in RAM, or anything fancy. Both are configured with ext3 (although mine has a BTRFS partition, for play) with normal journalling.

I'm happy with mine. I don't notice the speed increase, if there is any; I mostly went this route to (a) reduce the heat, (b) reduce power consumption, and (c) reduce noise. My wife's Acer Timeline is particularly silent, as the CPU fan never comes on. I don't know if I'd put SSDs in my server; HDs are too ridiculously cheap, and I don't need extra speed for my modest music/file/web server uses. But, so far, I've been entirely satisfied with their reliability.

I do back both machines up nightly, just in case.

Comment Since when did quality become optional? (Score 3, Informative) 551

I keep seeing this "good enough" meme going around.  At a company meeting, recently, management was espousing the same crap.

I can only hope that these people are plagued with "50%-good" products.  50%-good tires, that blow out ocassionally, causing an accident.  Maybe Joel would like some 50%-good surgery, or a 50%-good pacemaker.  How about getting to fly in 50% good airplanes for the rest of his life?

I'm not surprised that most of this bullshit is coming out a culture in which Walmart was able to become the success it has.  We needed something for a weekend project recently and bought the materials from Walmart, because it was closest.  What poor quality crap.  It'll all need to be replaced in a year, contributing to landfill and wasted resources.  I'm not going purchase from Walmart any more, and I'm not going to spend money on half-baked, crap-quality software, either.

Word gets around about quality.  It's the American auto-maker's nightmare right now.  Ford, Chrystler, Chevrolet... they're all struggling to reverse decades of built-up public perception about poor quality, even when some of them are actually making fairly decent cars right now.  It isn't quite the same with software; Microsoft has been making crap software for, well, ever, and they're still dominant.  But I think that if you take the monopoly factor out of it, software companies *do* suffer from delivering half-assed product to their customers.

Comment Netbeans, GNU Screen, and Gobby (Score 1) 302

Netbeans has a decent collaboration editor. The only limitations that bother me is the inability to interactively diff (which makes code reviews more difficult), and the fact that there's no cursor tracking. This means that you can't, for example, highlight some code you're talking about and have the other person see it.

GNU Screen is, of course, always an option if you can use a command line text editor like vim or emacs.

Gobby is pretty decent, although it's a bit more limited as an IDE.

I've always preferred NetBeans for this sort of thing, although nothing yet satisfies all of my peer programming requirements. I need an editor that lets one person follow another, and take turns editing, not something that just lets two people edit the same file at the same time. I'd argue whether the latter is of any use at all.

Comment Re:In Space (Score 1) 512

There's a lot of truth in what you say, although it isn't limited to environmentalists. You could more accurately have said:

Reasonable people: ...
Unreasonable people: ...


There are many reasonable environmentalists, and alarmist technologists. I'm not sure that it's fair to claim that environmentalists are opposed to testing; do you have examples?

And, while I do agree that the gainsayers, in this case, are very likely being alarmist, I'd also like to remind you that history is just as full of things that go:

(supposedly) Reasonable people: Let's use this wonderful new "Asbestos" technology!
Environmentalists: No way! It's dangerous!
(supposedly) Reasonable people: Err, no it's not


(supposedly) Reasonable people: Let's use this wonderful new "chlorofluorocarbons" technology!
Environmentalists: No way! It's dangerous!
(supposedly) Reasonable people: Err, no it's not.


In many cases, we find many years that the "alarmists" were right, after all.

Submission + - A Visual Expedition Inside the Linux File Systems (jhu.edu)

RazvanM writes: "This is an attempt to visualize the relations between the Linux File Systems through the eyes of the external symbols their kernel modules use. An initial plot was presented before but this time the scope is much broader. The analysis is done on 1377 kernel modules from 2.6.0 to 2.6.29 but there is also a small dip in the BSD world. The most thorough analysis is done on Daniel Phillips's tree which contains the latest two disk-based file systems for Linux: tux3 and btrfs. The main techniques used to established relations between file systems are hierarchical clustering and phylogenetic trees. Some other things that are presented include a set of rankings based on various properties related to the evolution of the external symbols from one release to another and complete timelines of the kernel releases for Linux, FreeBSD, NetBSD and OpenBSD. In total there are 78 figures and 10 animations. Happy viewing and commenting!"

Comment Re:repeat of ogg? (Score 1) 361

Now, 5 years later I have a large collection of ogg files that are essentially useless. No one in the mainstream uses ogg, despite the superiority and price.

Weird. I started out the same, but I'm still ripping to Vorbis ogg. When I first started, I easily found the Cowon D2, which supported ogg. When I bought my Android G1, hey! Guess what? The native media player supported ogg, too. A quick Google search turns up this page, which lists no fewer than 59 flash based portable media players that will play oggs, and 38 hard-drive based portable media players that do, too. There are 5 smartphone platforms that support it (some of those through third-party apps for the phones). The last two DVD players I've bought have come with support for ... what? Playing oggs off data CDs.

There are many mainstream companies that support ogg. Some don't. "No one," however, is simply incorrect.

Submission + - Does Microsoft's Bing have Google running scared? (cnet.com)

suraj.sun writes: Microsoft may have developed a contender that threatens Google's Web search dominance.

In a story headlined "Fear grips Google," the New York Post reports ( http://www.nypost.com/seven/06142009/business/fear_grips_google_174235.htm ) that the launch of Microsoft's Bing search engine has so upset Google co-founder Sergey Brin that he has top engineers working on "urgent upgrades" to Google's service. Brin is said to be leading a team to determine how Microsoft's search algorithm differs from the closely guarded one Google employs. The tabloid also notes that it's rare for Google's co-founders to have such a hands-on involvement in the company's daily operations.

"New search engines have come and gone in the past 10 years, but Bing seems to be of particular interest to Sergey," an anonymous source described as an "insider" to the newspaper.

A Google spokesperson declined to comment on the level of Brin's involvement but did tell the newspaper that the company always has a team working on improving search.

While Microsoft has a long way to go before it makes a dent in Google's business, Bing may end up being the only true alternative to Google if Yahoo decides not to compete in the search market ( http://searchengineland.com/bartz-continues-torpedoing-yahoo-search-20705 ) over the next few years.
