There are several new features that I consider worthy of particular mention. First of all, there’s the addition of a V4L/DVB driver that adds support for USB Video Class devices; this means that most USB webcams, video cameras, video capture cards, etc. will now work fine with Linux.
Barriers have been enabled by default in ext4. This improves data integrity, as it gives a mechanism for ensuring that the transaction information has been written to the filesystem journal before the commit record can be written, along with the rest of the write operation. However, Andrew Morton stated that it can cause a 30% slowdown, and thus the reason that up to now it hasn’t been enabled by default on ext3 or ext4. The situation may not be as severe for ext4, however, as the barrier process for it is less time-consuming than it is for ext3.
Yes, another post entirely about this website, but I think you’ll find it useful should you ever need to fix your comments in Wordpress.
This morning, I had marked 25 of the most recent Wordpress comments as spam. I use Disqus for new posts, but old posts with comments still use the Wordpress mechanism.
In Wordpress, comments stay in the database when marked as spam. This is probably done to train the spam filters. What I had to do was permanently delete all of the real spam comments and then set all the good comments marked spam (as the only comments marked spam that are left are the good comments) as good again.
I have Disqus on Wordpress, and it is set to only replace Wordpress’s commenting system on new or other posts without pre-existing comments. Now that more posts were without comments when they were marked as spam, Disqus took them over.
Setting the flags in the comments table in the database that Wordpress uses only solved part of the problem. Disqus was still taking control of the comments.
In the posts table, there is a column that contains how many comments there are for the post. This was modified when I marked all those comments as spam. I wrote a short little PHP script to look through all the posts and see if the number of comments according to the posts table was the same as the number of comments for that post. If the two numbers were different, I would change the number of comments in the posts table to reflect the actual number of posts.
I might put up a modified version of the script later.
As the bandwidth [usage] on CodingExperiments increases, I’m being increasingly pressured by family and friends to put advertisements on CodingExperiments to either cash in or pay less for hosting.
I’m not a pro-advertising person at all, so I’ve always said that putting advertising on a tech site is pointless as everybody runs Adblock Plus now.
But now, I’ve lost. For one day it’s a week now, advertisements will be placed on CodingExperiments.com. I would ask that you do not disable Adblock Plus to click on them. Don’t do anything out of the ordinary. If I make no money in one day, I’ll go back to a nice, ad-free website.
UPDATE (June 13th): Except for four clicks on the first day, no clicks so far.
Please share your opinions about the advertisements in the comments.
and yes, Voyagerfan5761, there is a Disqus thread below.
