Downgrading the Toshiba Satellite U305-S5077 to XP
I had to assist in the downgrading of a Toshiba Satellite U305-S5077 to Windows XP from Windows Vista last night, and it turns out that Toshiba does not make this convenient or easy, despite it being totally in their power to do so.
Here are the drivers you need, with handy links (in most cases, to Toshiba's own site, which should have this information, but does not.)
Update:Some users have reported these drivers to be non-working for their systems. I don't know if this means that some U305's are using new devices since I created this post, or if it's user error (I suspect a little of both.) So, please do take all due precautions when using these drivers, even though the majority of respondents here have reported them as operational.
Update, March 20, 2011: I appreciate all the folks taking time to thank me for this couple hours' worth of work. It really has been interesting to hear from some of the 9,329 people who --to date-- have been helped by this post.
But, that said, please DO NOT expect "custom support"; I have no particular interest in Toshiba laptops, nor am I regularly engaged in technical support, and so I DO NOT know how to help you with your specific model. I just figured I'd put this post up, and help others as a side benefit of the time I invested working on this machine for my cousin. In short, beyond helping point you to these drivers, and in the one case, actually hosting it, I cannot help you.
Many of these drivers have been reported to work for other "U305" models, but I do not and can not make any particular claim or warranty as to their suitability for use in models different from the actual Toshiba U305-S5077 that I actually personally put my hands on back in January 2009.
So, without further ado, here's the drivers:
Bizarre Linux-WordPress-PodPress issue
As there are legions of pages out there on the various "blank page" errors in WordPress, I'll add my own experience here, in the hopes of helping others.
I run, on behalf of a client, a wide array of WordPress blogs using the excellent PodPress podcasting plugin.
Some of those blogs suddenly started experiencing the dread "blank page" error. The logs were unhelpful, reporting a 304.
The problem wound up being a bunch of MP3's (the podcasts) that another contact of the clients' had uploaded for them, that wound up in the /tmp partition.
One quick "rm -rf /tmp/*.mp3" and everything was good to go.
I hope this is helpful to others; I know how many blind alleys I stumbled down trying to properly troubleshoot this issue. In the end, I just happened to notice 100% utilization of /tmp as I was checking the RAM usage. Troubleshooting this error is unfortunately made more difficult by a wide range of red herrings.
Funny Unix/Linux Commands
Some of these seem to be platform-specific, but here's a funny look at some odd results you can get out of your shell: [link]
% cat “food in cans”
cat: can’t open food in cans
% nice man woman
No manual entry for woman.
% “How would you rate Quayle’s incompetence?
Unmatched “.
% Unmatched “.
Unmatched “.
% [Where is Jimmy Hoffa?
Missing ].
Defeat Caravan.Ru Comment Spammers
I'm seeing people coming here looking for help the same way I was trying a few weeks back.
I was operating under the mistaken impression that temporarily blocking Caravan.ru IP blocks would take care of the problem, but every time I lifted the block, they came right back, usually within seconds.
Here's what you do:
1.) Get APF. (Advanced Policy Firewall) It installs very easily.
2.) Edit /etc/apf/deny_hosts.rules using your text editor of choice. (vi, nano, etc.)
3.) Add the following netblocks to this file:
212.24.32.0/22
212.24.48.0/21
212.158.160.0/21
212.24.56.0/21
212.23.128.0/20
217.23.133.0/20
212.158.168.0/21
217.23.144.0/20
62.213.64.0/19
206.74.0.0/16
144.94.0.0/16
212.24.36.0/23
217.23.128.0/20
212.158.160.0/21
212.24.56.0/21
202.53.8.0/21
Restart apf by issuing this command: /sbin/service apf restart
That should do it!
Safari Available for Windows
If you're like me, and have had to develop websites for an Apple-oriented client, and you use a mix of WinXP and Linux, you are probably stoked by the fact that Apple has released a version of Safari for Windows users.
I remember one project I did where the turnaround time in communicating by e-mail, phone, and IM about differences between Firefox and Safari's rendering took a considerable amount of time, and I've always wanted my designs accessible to Mac users, so I'm pretty happy about this.
Banning entire countries?
Recently, I've been having major problems with zombie computers from a Russian ISP doing a lot of comment spamming. This has occupied a very large segment of my time across the last week, resulting in a very tired and very fed-up sysadmin.
Ordinarily, such spammers are comparatively polite; they hammer you from one or two IP addresses, which, when you block them, they move on.
Not these guys. Near as I can tell, they've got control of a large part of the entire Caravan.ru IP block(s), because everytime I'd ban an individual IP, or even an IP range, using hosts.deny or iptables, they'd just pop right back up on another IP range.
Caravan.ru seems to use a lot of non-consecutive IP ranges, which has made my work considerably more difficult. So, I decided just to ban Russia altogether for a few days. Here's the tool I used: [link]
