A viable alternative to iPad for $300

September 4th, 2010 George Ou 13 comments

That’s the upcoming Archos 10.1″ tablet for $300 USD.  It looks like a very good alternative to the Apple iPad for the following reasons.

  • $300 is a lot cheaper than Apple’s entry level device of $500.
  • Speed.  Apple iPad’s killer feature is its speed.  These Android devices are finally catching up.  The PC and Mac OS can learn something from this.  Users care about speed.
  • Capacitive touch.
  • The accelerometer looks good, especially in the game demo.
  • Has an adjustable kick stand, something the iPad sorely needs.
  • Has a USB host, HDMI port, and SDHC slot built in.
  • You don’t have to install iTunes.

4th generation iPod touch pressures the android device market

September 2nd, 2010 George Ou 14 comments

Speaking as someone who would never install iTunes on his computer (which rules out Apple products for me), I can’t help but notice that the new iPod touch just made all the android mini tablets like the Ramos W7 or even the Dell Streak obsolete. There’s no 3G capability, but you can get a MiFi device that’s far more useful. The smoother UI in conjunction with the superior display is the killer feature of this phone, not to mention the iOS app store.
http://www.apple.com/ipod/

There might still be a market for 5″ and 7″ devices, but word has it that Apple is going to fill the gap between 3.5″ and 9.8″ soon.

I guess the good news is that the generic clone market is going to have to lower their prices if they want to be competitive.  The Ramos W7 android device costs $50 less than the entry iPod touch and it has an SDHC and HDMI slot as well as a larger 4.8″ LTPS screen which makes it a plausible alternative.  The big margin for Apple is the 32 GB and 64 GB models which you almost have to buy since there is no SDHC slot on the iPod and external readers like this are just plain ugly.  Still, Apple is putting the major squeeze on its competitors.

Realtek card reader drivers slow transfer rates 4 fold

July 23rd, 2010 George Ou 10 comments

I helped acquire an HP G72-250US 17.3″ with Core i3 notebook for a friend of my mother.  When I tested the SDHC card reader speed, I was shocked to find that read speeds would drop to less than 5 MB/sec after the first time read in Windows 7.  Once I uninstalled the software using CCleaner, the card continued to work but it would maintain its 20 MB/sec read speeds.

While I appreciate Realtek going to the effort of writing extra software, they really need better quality control.  I suppose I should be happy that at least this isn’t one of their silent data corruption bugs that I found a few years back.  The other thing that really bugs me is their massively bloated wireless network driver that forces you to install a bunch of extra wireless supplicants (like Cisco) on top of the Windows wireless client.  You’re forced to download a large EXE from Realtek which extracts and autoinstalls the driver without asking for permission.  I had to note the extract folder path and then uninstall the Realtek drivers, and then manually install the drivers from device manager by pointing it to the uncompressed installation folder.  It would be so much simpler if Realtek just provided the bare drivers.

HP needs to wise up and keep that software (and all the other crapware they install) off the system.  The PC industry needs to look in the mirror and ask themselves why Apple completely owns the $1000+ notebook market.

Piracy as a protest?

July 8th, 2010 Justin James 3 comments

Something that I have heard a number of times, is that people beleive that piracy (usually music) is justified as a way of protesting copyright laws that they disagree with. While I understand that they disagree with the laws themselves, the idea that piracy is a “protest” of some type is absolutely laughable. The fact is, a protest is pointless unless the people who can change what you are protesting (in this case, Congress, the RIAA, the record labels, the musicians, etc.) are aware of the protest. Simply copying a CD or firing up a BitTorrent client and downloading a song isn’t a “protest” no matter what you beleive about copyright law.

Look, I know the score with the record labels. I’m not going to debate it, because I really understand both sides to it and empathize with each one for different reasons. But when people try extending this to movies or software, it is just plain dumb. The economics around both give a lot more money to the people who put in the real work than the music industry. Let’s face it, the average programmer or even a gaffer on a movie set makes more than the average signed artist does. So don’t pretend that copying a movie or piece of software is even about something justifiable, because it isn’t.

If you want to have a true protest, try this: first, pirate the album. Next, look at the liner notes for the album, find out who the producer is, the songwriter, etc. Send them each a dollar or two (it’s more than they get in royalties), and a note explaining that you pirated the album that they worked on because you don’t think its fair that the record label is ripping them off, but at the same time, you don’t want to be the one ripping them off either, so you are including payment far above their royalties. Send the band or artist five dollars with a similar note, and encourage them to esell their music directly. Also let them know that you compensated the producers and songwriters as appropriate. Don’t worry about “studio musicians” because they got a paycheck to play and aren’t in the royalty game. If you’ve got a lot a nerve, write a letter to the record company explaining what you did as well.

And there you go. You accomplished your goal of having the music without giving any money to the RIAA or a record label, the people who can actually make the situation change (the artists, producers, and songwriters) are actually aware of your protest, and at the same time, you are not ripping anyone off.

I am sure there is an alternate approach that does the same thing. But the point is, if you claim that piracy is a “protest”, you need to get honest with yourself. You aren’t protesting anything, you are justifying ripping off the artists that you claim to love, because even though they see pennies on the dollar in royalties, they don’t see a cent when you pirate an album.

My experiments with Chrome, Opera

July 6th, 2010 Justin James 6 comments

I recently gave Firefox about a week of my life to see how I liked it. While I did not think it was perfect, it showed me that it is definitely worth exploring other browsers. So I decided to give Chrome a try, and then Opera. Chrome survived about a day as my default browser. To be honest, I really, really liked it… except for one huge problem: the tabs on the title bar. I work on two monitors, and the Web browser is almost always maximized on my main browser. About 20 years of computer use have trained me to click on title bars to switch applications, since they are larger than taskbar icons, and the application will not munge data or perform any actions when you do it. I also like to double click title bars to un-maximize. With Chrome, my behavior kept switching tabs and sometimes even closing them. Despite the fact that I really liked Chrome overall, this was a 100% deal breaker for me. So I gave Opera a download, and I saw that it took replicated this idiotic UI decision. I could force the tabs to be in their proper place, but only by also adding a useless toolbar above them, which was also unacceptable. As a result, Opera made it less than 10 minutes on my system.

Right now, I am back to using IE 8. I might give Firefox another week to see if I can deal with it, but it’s poor tab handling was driving me so nutty that all of the other things I liked about it were being overwhelmed.

My Firefox experiment

July 5th, 2010 Justin James 15 comments

At the advice of others, I’ve decided to give Firefox a one week trial (I’ve been an IE user since version 3 or 4 took me off of Netscape). I was willing to make the switch simply because IE is really, really slow. To be honest, the “usual suspect” list of reasons didn’t factor into the discussion for me:

  • Security – I think that once you turn off ActiveX for public sites (the IE default for a long time now), IE gets a lot more secure. Firefox has its share of security issues, and I think a switch for security gets you little advantage in the long run.
  • Stability – IE 8 has been rock solid for me. Even when Flash acts up, IE just closes the tab and if it keeps happening, IE stops it from loading on that page. Meanwhile, my Firefox using friends have been complaining about stability issues and memory leaks since version 1. In fact, it was a friend telling me that Firefox 3.6 really handles the crashing a leakages that encouraged me to try it out.
  • Add ons – From what I can tell, much of the problems that plague Firefox are actually problems with add ons. So for someone to tell me that I should move to Firefox for the add ons is really not a ringing endorsement.

For me, the user experience (UX) is everything, and IE 8 has been a good user experience. Firefox’s crashing and memory leakages have been showstoppers for me, the bad UX from those issues offset any positives. But with these issues solved, Firefox became a legitimate option for me. I am now at the end of a week of usage, and I’ve found a lot to like, and a lot to dislike. I am not sure if it is enough to convince me to make the switch permanent.

PROS

  • Speed – Firefox is noticeably faster than IE. I like that the most.
  • Form field handling – Some sites (Facebook, WordPress’ editor that I am using right now) do not handle vertical scrolling in IE properly, and they work fine in Firefox.
  • Spell checking – I love it.

CONS

  • Tab handling – Firefox may have invented tabs, but IE handles them much, much more nicely in terms of grouping them with colors and where newly opened tabs appear. I found an add on that seems to make the tabs better, but it does not work with the most recent versions of Firefox.
  • OneNote integration – IE’s “Send to OneNote” is much more useful than just printing to OneNote from Firefox.
  • Facebook – I hate to say it, but I use Facebook a lot. And it seems to work much better in IE than Firefox, other than the large textbox issue that I have in IE.
  • UI – The Firefox UI really reminds me of an X11 app, and that is not a compliment.
  • Accelerators – I got very used to the “accelerators” (especially “Map with Bing”) in IE, and I miss them in Firefox. Yes, there are similar items in Firefox via add ons, but they invariably use Google services when I prefer Bing (especially maps, where Google Maps have burned me too many times).

If I could give IE 8 the spell check and speed of Firefox, or if Firefox had the better tab handling and OneNote integration, I would be happy. For me, both browsers meet my needs on the really big UX stuff now (security, crashing, resource leaks), so the details are what are important. And right now, I don’t think either browser is so superior to the other than I won’t miss something from the other.

I think what I will do is give Chrome a similar one week trial, and perhaps Opera as well. While I am not convinced that switching browsers will revolutionize my life, I do spend enough time in one for it to make my life easier or more difficult.

iPhone 4 can’t actually hit full 802.11g speeds much less 802.11n

iPhone 4 Wi-Fi performance benchmarks

We were surprised to see that Anandtech only managed to get Wi-Fi performance of 7.2 Mbps downstream and 7.96 Mbps upstream using the SpeedTest.net app for iPhone OS. We ran our own tests and found that the iPhone 4 can sustain 20 Mbps over Wi-Fi. These are much better results, but they fall short of optimum 802.11g much less 802.11n.

Fix for 0x80072f0c error (502.3 – Bad Gateway) for reverse proxy to SSL with IIS

June 20th, 2010 Justin James No comments

I’ve spent most of a week struggling with this error. I set up IIS to reverse proxy to a backend server using the URL Rewrite module and the Application Request Routing (ARR) module. The first problem I encountered was that when using the “Reverse Proxy” wizard/template under URL Rewrite, it kept blowing up, giving me an error 500. The solution for this was to first go to “Server Variables” and add “HTTP_ACCEPT_ENCODING” as an allowed server variable. Next, I had to go into the configuration and set HTTP_ACCEPT_ENCODING to be passed to the destination server with an EMTPY value. You can’t do this direction from the configuration screen, because that demands a value. You can do it in web.config (or anywhere in the configuration chain). I did it by going to the “configuration editor” in IIS Manager to edit the value raw with no validation.

The next problem was much trickier. The reverse proxy template was able to handle carrying over SSL just fine to the backend server, but when I tried to access those links, it would blow up, giving me an error 502.3. Turning on detailed error reporting showed me an error code of 0x80072f0c and the text “HTTP Error 502.3 – Bad Gateway”. Full details showed more confusion under “possible causes”:

The CGI application did not return a valid set of HTTP errors.
A server acting as a proxy or gateway was unable to process the request due to an error in a parent gateway.

This made no sense to me at all. After hours of work on this issue, I finally found the problem. The virtual directory on the destination server (the one BEHIND the proxy) had been set to “Accept” client SSL certificates; this needs to be set to “Ignore”. While the site itself was set to “Ignore”, the virtual directory had been created with “Accept”, causing the problems.

Cheap HTPC mini trackpad and keyboard

June 16th, 2010 George Ou 2 comments

Note: Just trying out the video review format for the first time using my Canon Kiss X4 (Rebel T2i or 550D).  Maintaining focus and handling the product and talking at the same time presents its challenges, but I hope I can get used to it.  The depth of field is very shallow but at least you can see everything clearly with the exception of the darkened on/off switch.  I’m not sure if there’s any benefit to using 1080P for this video, but at least it makes the 360P and 480P and 720P version look very clean due to down sampling.

This is the iPazzPort bluetooth keyboard and trackpad. The name sounds funny where I can visualize a picture of a fat cat sitting on the couch with the caption “I can haz remote controlz?” But jokes about the name aside, this seems like a very viable product.

At $42 shipped from China (or $50 at buy.com), it’s the lowest price that I know of for a mini bluetooth keyboard/trackpad. Lenovo has something for $60 and Logitech has the DiNovo for $150.

The keyboard has a backlight for darker rooms and the keys offer some good tactile feedback while the trackpad and scrollbar work smoothly and accurately. It’s also a thin device with average build quality that feels pretty good in the hands overall.

BlueTooth paring was simple and you didn’t need any special drivers. Just push the button at the bottom and scan for it in the Windows BlueTooth user interface, then key in the pairing key and hit enter on the keyboard. The wireless range works well beyond 30 feet so it should work in any size living room.

The bottom part of this chassis feels slightly loose and the on/off button doesn’t glide on and off easily, but I’ve just left it in the permanent on position since the device goes to sleep on its own to conserve battery life. It has a lithium ion battery that recharges via the USB port, but I don’t know how long the charge lasts when I don’t bother turning the thing off. I’ll post an update on battery life days or weeks later when I need to recharge this thing.

Overall, this is a good form factor device that works well. If you need to control an home theater PC in the living room, I don’t think there is a more affordable option than the iPazzPort.

How to re-enable ISO 100 on Canon Rebel T2i

June 9th, 2010 George Ou No comments

After selling my Canon Rebel T1i on Amazon for $565 (minus a $47 commission for Amazon), I bought a Japanese branded “Canon Kiss X4″ camera known as the Canon Rebel T2i in the US market and 550D elsewhere last week off eBay.  Why would I do that?  Because the Rebel T2i has been “out of stock” for the last 4 months in most places with no end in sight and the few people who do have it on Amazon or eBay are selling it for $1000+ which is $200 more than the retail list price.

Update 11:45PM – Looks like Amazon and Newegg just got the T2i body in stock for $799.  I would have gone this route had I known, but I didn’t get a bad price on the Kiss X4 kit with lens for $830.  The risk I take is that there is no warranty the first year.

The Kiss X4 didn’t come with a warranty (though I’ve never had a Rebel SLR fail on me yet), but the $830 I paid for it including the standard lens kit wasn’t a bad price.  Of course now the seller is trying to point me towards an $80 3rd party warranty to which I am declining because my camera isn’t likely to fail in the first year.  The other problem is that the camera only comes with a Japanese manual but that can be solved by downloading the English manual in PDF format.

The image quality has been unbelievably good when you force it to manual mode and ISO 400 and below, but I was stuck at ISO 200 and above.  ISO 100 was simply not presented as an option and it was maddening.  I emailed Canon support and they replied to me the next morning with the answer.  It turned out that “Highlight Tone Priority” was enabled which requires ISO 200 and above. After disabling that feature, ISO 100 was available once again.

Note that you need sufficient light just like you do in photography, and it might be hard to use ISO 100 in a dim room because you won’t be able to achieve the minimum 1/30th of a second virtual shutter speed (physical shutter is locked open).  In automatic mode, the camera will adjust the ISO up automatically but in manual mode, the scene will just get dark and under exposed.  That’s actually a good thing because sometimes you want the scene to be dark.  It was getting annoying and unnatural in automatic mode where the camera would literally make everything look like daylight even when you’re shooting a night scene with existing light.  Manual mode also solved the erratic exposure problem which may have had something to do with the fact that I was using a third party 28-70 F2.8 lens from Tokina.

Automatic focus “works” but it is very noisy and very slow.  It hunts around and the camera still jumps to a high ISO even if you’re in “manual” mode.  Using manual exposure and manual focus solves all these problems and focusing is much smoother, more natural, and faster so long as you keep your eyes close to the LCD view finder so you can see the details accurately.

Here was the first short sample I shot and posted on YouTube.  Note that you can bump it to 1080P mode.  And yes, it’s the same little kitty all grown up.
