Green has become the color of choice for the protesters in Iran, red is quickly becoming the color shed.
In support of these protesters, and protesters from all around the world I have turned cryptohash.net green and created this banner:
Large PNG
Small PNG
Feel free to use and re-use these banners.
If any one can reach any Iranians who need a secure gateway to post news, videos, and twit – please contact me I have facilities to allow a small number of ssh users to do dynamic port forwarding (Socks 5 proxy).
Greetings.
Just thought I’d let you know that I spent a couple of hours making cryptohash.net a little faster, a little meaner and a little smaller.
Through the use of APC (Advanced PHP Cache) it now caches the generated page and all the functions pulled from mcrypt. using the tightest of tight css files I’ve reduced the download, and shrinking 3 whole bytes off the images was also achieved.
I was also thoughtful enough to provide a notice for the 500 odd IE6 users that have visited this month – STOP USING IT!
All in all the improvements mean the average page downloads in less then 6 seconds on a 56k modem
So for all your SHA/MD5/etc/etc/etc needs, feel free to pop on over to “cryptohash.net“http://cryptohash.net
I’m sorry but I find it immensely amusing that someone could be lazy enough to just use a signed 32 bit integer in a twitter app.
Seriously, even an unsigned 32 bit integer isn’t a good idea.
At last check, the current ID is 2,161,653,083 and the rate of twits is 156 twits per second. So lets do some simple math here.
Lets not bother with the signed 32 bit integer, and skip streight ot the unsigned 32 bit integer.
((2^32) – 2161653083) / (156 * 60 * 60 * 24) =
(4294967296 – 2161653083) / (156 * 60 * 60 * 24) =
2133314213 / 13478400 = 158.28 (days)
So, in less then 159 days the unsigned 32 bit integer will roll over…
Now, lets do the same math with an unsigned 64 bit integer
((2^64) – 2161653083) / (156 * 60 * 60 * 24 * 365.242199) =
(18446744073709551616 – 2161653083) / (156 * 60 * 60 * 24 * 365.242199) =
18446744071547898533 / 4922880455.0016 = 3747144428.99 (years)
I don’t think anyone will care about twitter in as little as 2 years, so a 64 bit unsigned integer will probably do the job, but you never know – people might start posting at 300 or even 600 twits per second.
Do your bit to save twitter, only twit when you absolutely need to!
Don’t know how many people who hit this site are actually local, but I thought I’d plug a local lan.

So, after 2 years of fighting the government (Specifically the incompetence of the Department of Education, Employment and Workplace Relations) I finally get some of the money owed to me by my previous employer.
Now I’m about to embark on another fight, how hard do you think it is to bring a girlfriend of three years to Australia for a 3 month visit on a tourist visa – fully sponsoring her, providing her accommodation, food, and money to spend here?
Well, after paying two $100 application fees, and providing cover letters, statutory declarations, and even an affidavit sealed with a law firm’s stamp promising she’ll return home – all we’ve got is two identical rejection letters.
I’m left wondering, does my $100 application fee become a bonus to whoever rejects an application?
I’m quote prepared to concede that my girlfriend’s situation in her country is not the best for supporting her case, I’m aware she has nothing but her family to return home to (which the Department of Immigration and Citizenship don’t seem to think is enough reason), but we’ve gone to a great deal of effort to explain our situation and make guarantee’s and promises (which have penalties in BOTH countries for breaking)
It’s my understanding that a reviewing agent has a degree of control over an application, to use his or her own judgment, then why are we getting carbon copied responses to these applications, I’m yet to confirm it, but I suspect it’s the same person denying us both times, power gone to ones head perhaps?
I mean, it’s not like she’s asking to immigrate here, she’s asking to visit, and the reason? To spend some time together, getting to know each other, before we move forward to the next step in the relationship. To take time planning and preparing – It’d be MUCH easier if I just flew there, married her and brought her back – that’s not the right way to do this though.
I’m sure if I threw enough money at the right person I wouldn’t have a problem bringing her over…
I’m getting a little tired of the government in this country and it’s various power hungry and money grubbing departments.
First it was the complete and total incompetence of the Department of Education, Employment and Workplace Relations, every single day I face the incompetence of the Department of Transport (and the government owned company Queensland Rail), now I face the incompetence and possible corruption of the Department of Immigration and Citizenship – Don’t get me started on the corruption of the Department of Child Services, or the incompetence of Minister for Broadband, Communications and the Digital Economy
