TechCrunch points out that even ex-Bloglines-founder Mark Fletcher twittered that Bloglines sucks:

Bloglines, please stop sucking. It’s been a couple weeks now. I don’t want to have to move to Google Reader. Sigh.

According to Michael Arrington, the major problem with Bloglines is that it doesn’t update feeds with any frequency. But that’s not the only thing; the site itself is slow, hard to navigate, and hasn’t been updated in literally years. Here’s the UI that’s been in use since at least 2006:

Ask, please update me to something modern!

The beta design that Bloglines has been cooking up is nearly entirely worthless; it takes a bad design, and essentially reduces the amount of on-screen contrast. It’s also still pretty slow:

Here’s an interesting, funny blooper from their homepage refresh (it looks like Ask, when they bought them, finally figured out the homepage was extremely ugly):

That’s right, the “screenshot” for their mobile bloglines interface is actually of an iPhone checking voicemail? What?? How is that possibly related to an RSS reader’s mobile interface…

Gizmodo has a new review of the Western Digital Sharespace 4TB personal NAS product that just came out, and it’s absolutely glowing:

Western Digital’s ShareSpace Storage is a steely, cubular vault of NAS with fast Gigabit ethernet that brings enterprise-level centralized storage down to the small business and deathcore nerd space.

For $999 you get 4TB of storage (2.66TB actually free w/ RAID5), sluggish transfer speeds (10.5MB/s writing and 12MB/s pulling data), three USB ports, and Gigabit ethernet. You could get a faster Drobo for $100 more. And, in my tests, the better looking Drobo gets 16MB/s, and is also hot-swappable. You can buy the enclosure and put in 1.5TB drives to get a 6TB rig if you are so inclined, something that’s less possible with the prepackaged WD NAS solution.

I’ve had bad experience with Western Digital internal/external hard drives; they just die on me (and all the friends I know) a lot. But, I don’t own a WD NAS, so if you have one, let me know your thoughts!

If you’ve thought about whether upgrading from WP Cache 2.0 to WP Super Cache is a good idea, hopefully this benchmark will convince you. I followed my instructions on benchmarking Wordpress with Apache Bench on four configurations of this blog’s main page to measure performance:

1. Without any caching plugins
2. With WP Cache 2.0
3. With WP Super Cache (no compression)
4. With WP Super Cache (compression enabled)

The results show that WP Super Cache is a clear winner, performing 225% better than the older WP Cache. Here is the raw data I gathered during the test:

No caching:
Requests per second: 22.81 [#/sec] (mean)
Time per request: 4383.559 [ms] (mean)
Time per request: 43.836 [ms] (mean, across all concurrent requests)
Transfer rate: 613.75 [Kbytes/sec] received

WP cache:
Requests per second: 872.30 [#/sec] (mean)
Time per request: 114.640 [ms] (mean)
Time per request: 1.146 [ms] (mean, across all concurrent requests)
Transfer rate: 23549.46 [Kbytes/sec] received

Super cache (no compression):
Requests per second: 1518.90 [#/sec] (mean)
Time per request: 65.837 [ms] (mean)
Time per request: 0.658 [ms] (mean, across all concurrent requests)
Transfer rate: 41150.81 [Kbytes/sec] received

Super cache (compression):
Requests per second: 1960.39 [#/sec] (mean)
Time per request: 51.010 [ms] (mean)
Time per request: 0.510 [ms] (mean, across all concurrent requests)
Transfer rate: 53108.70 [Kbytes/sec] received
