I have a Samsung ML-2010 laser printer for 4 years. You can find the post of it. the day before yesterday, when I want to print something, it did not work. I tried to fix it. All failed. The red and green lights kept blinking.

OK, it is time to get a new one, I thought. I checked Bestbuy, Stalples, Office Depot, Future Shop, etc. Compare the price and features from All-in-one laser printer to wireless printer. Color laser printer is not in my consideration.

I make the decision that Samsung ML-1915 is the right one for me.

Actually, I just need a laser printer for print only. Scan, copy are not necessary. Wireless is also not must have. I use DNS-323 as a printer server. All computers in my home can access the printer through DNS-323.

Samsung ML-1915 is on the market last Oct. Not a old product.

I have a WPMU installation used for years. One MU plugin I use is Ada WPMU Sitewide Feed.

Until Wordpress upgrade to 3.0. It has multi-site support internally. So, upgrade WPMU to WP 3.0.1.

The problem just found that Sitewide feed does not work any more.
No content in the feed.

I went to the author site of this plugin.

In the comment part, Brad Williams pointed the solution to fix this problem.

I do like to mod my Blog time by time. And also check the performance of website often.
Now, I find UI of one of the best testing sites is changed. It is WebPageTest.

The new look is clear and fast.
OK, the point is not his UI or performance. I am talking about my blog. How fast it is loaded and easy to navigate.

To optimize my blog, I implement to speed up.

0) Merge CSS files into one CSS file.
1) Use minify tool, or Yuicompressor from Yahoo,to minify CSS and JS files.
2) Use CDN, Amazon CloudFront, to serve some static files, including CSS, JS, Images.
3) Enable gzip for CSS and JS and Html.
4) Add longer expiry date for static files.

The testing result of David Yin Blog shown as blow.

I did the upgrade of my Asus O!Play last month.

It is great to have so many features on it and keep add new features when upgrading.

I have written a post about how to Upgrade O!Play firmware. It is helpful. Because I saw lots of people doing the search and landed on my post to get the guide of upgrading.

Let us see what is new in 1.29N firmware.

The previous post I wrote explain why 500 internal error happen when MovableType publishing.
At the last, I promise that I will tell you how to solve this problem without upgrading your sharing host to VPS.

KEY point: The 120MB memory limit is per user.

If you know that, the answer is simple.

In one Dreamhost account, you can create many, many users. So
Create a new user for Movabletype powered blog.

Because my blog is hosted on Dreamhost, the limitation of shared account is always bothering me.

About one or half years ago, any time I rebuild this blog, 500 internal error came out. I have to try a lot of time to rebuild, maybe 10% success.

I have no idea how to solve this problem. Previously I knew Dreamhost has CPU time limit. Later, they remove this limit. But they did have some limitation for shared account.

The following is the response from Dreamhost support.

It's being killed for requesting an amount of RAM (memory) that puts the
total usage for the account over the limit:

2010-08-05 10:58:17 procwatch2 INFO: Process(pid=28759, name='mt.cgi',
uid=davidyin(1659020), tty=None, cpu=49.7, rss=52068.0, vsize=102664.0):
kill for total RAM

That's from the process monitoring logs. It's likely the amount of data
it's needing to do its job isn't the problem, but your total usage is so
close to the limit, that's puts it over. In fact, you've got more than 10
thousand kills in the logs, so this is not an isolated occurrence. Your
total usage is hitting the RAM limit very often, so it's possible one or
more of your sites has a bit of high usage, and needs to be addressed to
reduce the occurrence of this. This article may help you track down
what's using the most memory:

You may be tired of deleting spams or spammer account from your site. Sometimes your site is in the list of spammer. And also most of time the spammer are coming from the following top 10 countries.

1. Korea
2. China
3. India
