Blogger is not updating web pages correctly -> the fix

I've just discovered that nothing I've published since Dec 11th is appearing on the primary web page (front page) of Gordon's Notes.

My posts are all visible in Blogger, they are being published, they are appearing in the monthly indices, they show in my feeds, but the main page isn't displaying them.

Weird Blogger bug. I'll see if I can fix it by switching templates.

Update: It was easy to fix. I made some small edits to the most recent post that displayed on the main page, then saved it as draft. All the missing posts then appeared on the front page. I then republished the "bad" post and all seems well. If that hadn't worked I would have tried editing the oldest "hidden" post.

Macintouch - scanning tips

I'm reasonably good with a scanner, but I still appreciate these tips ...

Macintouch - Scanners

... Just to give an upper bound on the required resolution, standard 35mm film has a resolution of approximately 4000 lines per inch. Printed material is lower resolution, though I do not happen to know it off hand.

If you are scanning slides or negative, there is no point at scanning the film at more than 4000 pixels per inch; there simply is no additional information beyond that resolution.

For printing, a quick rule of thumb is the image resolution should be three times the printer resolution. If you have a 100 line per inch printer, then your image should be 300 pixels per inch after any size conversions (e.g. an image that will be 4x4 inches on a page should be 1200x1200 pixels for a 100 line per inch printer).

Note that on a typically 72 dpi monitor, the same image will only need to be 288x288 pixels)...

Microsoft's amazing WLW team also did Onfolio?!

I was happily scanning the release notes for the sure-to-excel WLW 2009 release when I came across a surprise note ...

Windows Live Writer 2009 RC released « whateverblog.

... On a more reflective note, this was the first full milestone (Beta to RC) we did without Charles Teague, our dev lead and voice of reason since the earliest days of Onfolio...

Onfolio is the only Windows app besides Windows Live Writer that I use and admire. I'm quite sad that Microsoft bought it only to kill it.

So one team did both products.

They must be Minnesotans.

I hope Microsoft is paying 'em very well!

Windows Live Writer news: 2009 and Blog This for Firefox 3.0

The really big news on one of my favorite apps from any vendor is that Joe Cheng has released a version of the "Blog This" add-on for Firefox 3. So we don't have to follow Joe's prior workarounds. Unfortunately it's in "sandbox mode" and won't be generally available until it collects a number of positive reviews.

So take a moment, register as a Firefox add-on tester, and contribute your five star review with a big thank you to Joe. My guess is he had to make time from his Microsoft duties to get this out.

In comparison, the announcement of a new version of WLW is a minor detail: Windows Live Writer 2009: Release Candidate. I mean, it's not like WLW 2.x was missing very much. The only WLW version news that would excite me would be a Mac version, which falls into the hell freezing category.

There's nothing in the features list I care about. Really, what I'd most like is a way to search against the titles of the post history list, and have other ways to manage the list of past posts. [See updates. Turns out the preview has some nice fixes to minor bugs and some great new features – like searching the list of retrieved past posts.]

WLW 2009 is bundled with "Windows Live Essentials", but I think you can choose which to install.

I'll wait for the release version. It's hard to improve on something as fine as WLW 2.x. Except, of course, by releasing the Firefox Blog This add-on.

Update: Joe commented that Firefox "Blog This" is a certified Microsoft product, not solely his project. Joe also tells us that the new version of WLW has the title search feature I wanted, implemented as filter.

Guess I'll have to test earlier than expected!

Thanks for the correction Joe, and thanks for your work and that of the WLW team.

Update 12/23/08: Blog This! is still stuck in the sandbox, so it needs more reviews. Works great, of course. WLW 2009 preview looks very good, so I’m glad I didn’t wait. I love the “filtering” feature – but I think it’s better than title filtering. I think it’s searching entire posts. They’ve also fixed the minor but annoying bug where the display of some labels/categories/tags for Blogger was truncated. The problem’s been long understood, but it wasn’t serious enough to justify a patch outside of this update. You have to uncheck a few things, but the new Windows Live installer will eventually agree to simply update WLW 1 and the IE toolbar.

I especially like slipstreaming SP 3 into XP Installs.

Reason over fashion: Yellow iPhone cases

I like my Clarifi case with macro lens, but since it turned my white iPhone black it's darned hard to find around the house.

Turns out, Reason is not quite dead. There are yellow iphone cases for sale. There's even a fire engine lime yellow-green case (several, actually) that would really make my phone easy to find.

I'm impressed.

The state of webcam-based low cost business videoconferencing

ver in Gordon's Notes, where I keep my ravings, I've opined on the root causes of the very slow development of useful and reliable low costs business videoconferencing.

Not for the first time, a solution seems to be almost in reach. It's been a longtime coming.

We've almost got reliable 640x480 (or more) 15fps point-to-point video with reasonably sharp edges and decent management of suboptimal lighting. That's enough to support facial expression tracking, and to enable sharing physical white boards.

Here's my summary of the state of the technology based mostly on my personal experience:

1. There are now reasonable quality USB 2 webcams, but focusing beyond 10 feet can be a real problem. Autofocus, even when it exists, is slow and unreliable.
2. Current webcams have very limited dynamic range. They seem to be tuned to keep from blowing out the high (right) end of histogram, so contrast extremes produce a lot of dark areas. Glare from reflected lights are a real problem. We need next generation sensors to improve the dynamic range.
   
3. Our CMOS (vs CCD) webcams have surprisingly good light sensitivity, even with small lenses and tiny sensors. I often find better results with relatively dim but indirect lighting.
4. I'd like to see some levels on the webcams to help with orientation. Oh, and a $%!$! tripod screw too. Velcro tape and black tape are most helpful, yeah, just like in the movies.
5. Relatively modern laptops seem to have just enough horsepower to do at least 640x480 at 15fps with the newest variants of adaptive h.264 compression. That seems to be the current practical limit.
6. Our networks are a problem. Attacks on BitTorrent seem to be taking out iChat, and possibly other video conferencing software. Comcast gets a lot of criticism; but it may be regional and it's not clear that DSL is always better. Comcast @Work may be better, but I have no real evidence yet. [see update]
   
7. Gmail based Google Video Chat (Vidyo technology) has given us the image quality we need on both XP and OS X. It hasn't, however, been very robust. [1] GVC is point-to-point, no multicasts. It also has voice quality that's sometimes excellent, but we prefer to use standard phone conferencing.
   
8. Stack Overflow likes Oovoo and Adobe Connect. Both have some multi-user support, but in our tests OOvoo had a lot of dropouts. On the other hand, we've had GVC issues as well.
   

I'll update this post as I learn more.

[1] Incidentally, Google's help forums are a waste of time. I think the XP to OS X connections have problems when a corporate VPN or firewall is involved, the XP to XP connctions seem more resilient.
