our Institute decided to upgrade the Exchange mail server to the latest version. Hence the mail server was shut down for approximately 2 days/48 hours (4th Dec evening to 5th Dec noon).
Poor bastards..it took them 2 days of complete shutdown, just to update their email server?
yeah, i saw "Exchange".. so what to expect? But still. They couldn't have installed in on a second server, and copied the configuration? Why two friggin' days of complete backup to upgrade some software from one version to another?
One of the few examples i've encountered is the PowerDNS converting from closed to open source. They simply found it easier to sell support for an OS product, rather than getting license fees for the closed one.
I too was hoping to hear more such stories. Anyone have some to share ?
Just thought you should know.. if you enable HTML mail in outlook, and write something fairly simple, you'll end up with 2 or 3 points in spamassassin. Things like "start but no end html tag", "no body tags", various illegal (non w3c) tags, lack of proper mine separations, attachments as "winmail.dat" instead of original files etc.. Outlook is a very very very crappy email client.
I work for a small webhosting company, and every single day we have to explain to people that their mail sent with Outlook, will never reach clients because they achive too much spam score, sometimes well over 10!
(Please note, i didn't say anything about the wiz-wiz presentation/sceduler stuff, just that it simply cannot write proper HTML mail)
Well, you mention $40. Tried buying Star Trek TNG on DVD ? Amazon retails them for just over $100/season. (including their 25 % discount). That would make me pretty poor if i'd buy the 7 seasons.
Perhaps Friends is cheaper as you say, but that's not true for all TV series.
When someone tries to charge something like $700 for some plastic material with IP produced in 87-94.. i think that's close to robbery. (Not that i can use that as an argument to steal it, but nevertheless, i understand those who do).
I think, the only reason Microsoft products are buggy, is because they have SO MANY USERS using them. Sorry to say it, but that comment is so full of s**t... Let me give you an example.
Quota manipulation tool in Windows 2003 Server. On a machine with (we have a few) over 500 users, you sometimes want to edit the quota for a certain user, say "john doe". If you start the program, all users are listed as:
{1:-30989-bb3s--fdslj-rubbhish::} something..
If you wait a few minutes, one or two entries might actually end up having that replaced by their real name. I've made the experiment, and I had to wait well over an hour before most of the entries were populated!
Now you say, you are supposed to search for them! Great idea, there is a "Find" function in the menu. Lets try and use it... oh wait.. it only searches in already revealed entries.
Ergo: when a customer calls and want to buy more quota, you cannot find the entries by less than waiting for well over an hour! The only workaround i've come up with so far is to enter that users home dir, find disk usage manually, sort the quota-list by usage, and start guessing.
Now how is that for crappy software ? Ok, you are correct that it's because there are many users on the system, but why the hell does it take 10 seconds for it to find the name of a single quota entry?
Some MS software is decent, but most of it is just plain friggin' crap!
If you are a lousy programmer and cannot read the code, here are some hints;-)
More seriously. Make sure you have Shockwave/Flash installed on the live cd's, or people trying out the browser experience will get pretty disappointed. (Visiting their favorite page, and it "doesnt" work.
Perhaps he is refering to "Applications" such as the "Nvidia Driver Software" for Linux? That has to be rebuilt/recompiled if you switch kernels, even when switching between 2.6.9-r1 to -r2 etc (Gentoo!).
Perhaps he is not talking about applications such as "Emacs" or "vim" ? (Or, he just finished his crackpipe:-)
But seriously, With a couple of exceptions I can think of. Namely the e-commerce shopping cart patent, there hasn't been much of a threat to smaller development houses.
Hm. i just implemented an e-commerce shopping cart and sold to a customer yesterday. Would that have triggered a patent infrigment?? You guys.. you need to fix your country, it seems broken ? What about the "land of the free", "the land of opportunity", "the american dream" ?.
Or perhaps, the american dream has switch to being able to sue one rich person or a company one during your lifetime, and becoming rich beyond expectations (unless you are sued by someone else persuing the dream...)
I've always hoped that I could work in the US a couple of my years, but i get more and more hesitant.
Except that I have yet to find the mystical "specials" page, where you can buy an Apple computer for something for less than $799. That site is spelled a bit differently:-)
Yea, i came to think of the xbox as well. Your argument is a bit flawed since it (the xbox) will only do twice as much if you mod it (bigger HD, xbmc etc). but still. Also, it does not have TV tuner built in.
The tech specs are exactly the same ? (celeron 733, 64 mb ram). Could they be built on the same hardware, but with an extra tv tuner card or something ?
I find this a bit confusing (not your post, but the issue you mention). You have TOS that does NOT allow you to listen to incoming ports? (ie, a server).
Could anyone please tell me what I'm supposed to do with something like 30Mbps/5Mbps if i'm not allowed to serve some ?
Is this to prevent stuff like bittorrent/gnutella/napster/direct connect ? (Its a bit strange if those are classified as "personal server" anyway).
The ISP's i know of (here in Scandinavia) encourage me to set up my own firewall system, use NAT (some even have linux faqs on how to configure iptables), and run servers. I pay for my bandwidth, why should I not be allowed to use it ? A game server, a web server, why not?. Of course, my TOS clearly states that I'm not allowed to do "commerce" on my DSL line, but that's a different thing... or is it ?
1. How to setup replication with different architectures including master/slave, master/slave/slave (another level), replication rings, dual master replication with slaves and more.
2. RAID (software vs. hardware), RAID types, IDE vs. SCSI. I know. I'm sure you've thought of these things already but most people will find something new here because there is a lot on it. It is quite dense.
What on earth does this have to do with MySQL specifically? And furthermore, if you dont know about _RAID_, and need to be told the benefits of SCSI/Raid, do you really think you need MySQL clustering ? Any PC/Server with enough ram will push queries like a maniac. Also, check #4...
3. Selection of an OS. Seriously. It actually compares threading models on OSes compared to performance with MySQL. This is great stuff.
Great, now that i've bought this book, i'm supposed to _CHANGE_ OS in my server farm, just to gain a few more queries/sec ?
4. Selection of a filesystem on an OS. Yes, nitty gritty. Includes talk about journaling vs non-journaling benefits and warnings.
Filesystems? Oboy, anyone who knows about SQL performance knows that if you access _DISK_ during execution, you are screwed anyway.
5. Load balancing mySQL. How to do this through a load balancer. Why and how it's different than load balancing web servers.
This seems like a decent chapter.
6. How to backup live using replication.
DOH! We are talking backup here, right? Backup means archiving a copy of the database. MySQL allows you to use the magic command "cp" (or scp, or rsync, or..) Best # so far...
7. I love this: Detailed information on how the replication system actually works. I love understanding the inner workings because then I know how/why things went wrong.
The updated node sends commands to the other machines to update as well. If something goes wrong, you could rollback the transaction.
8. The benefits of myISAM/InnoDB table types including how they store/retrieve data, the features available, etc.
This one could be interesting as well.
I dont mean to troll here, but most of those #s are either offtopic or irrelevant. To create a high-performance *SQL database, just have enough ram, ie, _NO_ disc access except for sporadic logging etc. Furthermore, it's title is "High Performance MySQL", so what we are interested in are what bottlenecks we might run into with MySQL specifically, not stuff like disc/raid. Tell me about some of the quirks with indexing, tell me how to tune threads, how to determine good from bad queries, how to monitor performance.
If you need clustering for some reason, just create a low latency backbone for master/slave connections. It's easy to configure, just read the docs.
it's ok.. he's getting punished via the slashdot effect right about now I guess you never read his previous article, "dual-head bandwidth setup", aka "Aviod the wrath of slashdot";-)
Even if it saves me $1 on my electric bill (it actually saves a bit more than that) it's beneficial. That's a beer, a burger, or $1 to go towards something else that's more important than being able to have Word open on one monitor and AIM on another. You pay for your electricity ?.. MAN, you need to phr3ak s0m m0r3!;-)
In some mathematic tasks, when performing math operations with large (>32bit) numbers, things are speeded up significantly. If you want to perform a sum(10,10) operation, its probably just as fast on 32 as on 64 bit CPUs (one CPU cycle). If you perform sum(3000000000,3000000000), you can do this on one cpu cycle on a 64 bit, but you probably need 2 or 4 cycles on a 32 bit. (2 or 4x faster). The dual FPU and 64 bit was the reason the systemX became the third fastest computer in the world.
Office 2004 is the Applized version of Office XP. More info here. Outlook is renamed Entourage btw...
And... it's probably more correct to say that Office XP is a Windowized version of Office 2004, since much development/innovation at Microsoft is implemented first at their Apple department in California (not in Redmomd like the rest of the stuff). As an example, they tried out a sidebar in IE for Mac. Dont think it ever made it to Windows...
I wouldnt say you are insane, just that you misread the PC/Mac stuff. Some apple software ends up on win32 though, like iTunes.
Considering how Apple treats it's customers that did not shell out the several hundred bucks for Apple care those guides are badly needed.
My PowerBook (a 550) had several dead pixels, and I reported this to my local apple reseller after 18 months. They told me to call apple support, so I did.
I talked for 5 minutes to a lovely girl on Ireland, she mailed me an "extended warranty" something paper, and then Apple (through my local store) replaced my screen for free. The warranty had expired 6 months ago, and they still did it for free.
The lovely irish girl only asked one question, "Were there any dead pixels on the screen before the warranty expired", and i (truthfully) answered yes. End of discussion.
Apple does take good care of non-Apple-care customers as well.
We (my company) have bought loads of dell servers the last year, and it's perfectly OK to buy them without Windows. We dont even buy them with Linux (RH), we buy them blank.
Is this different in the US, or is it just workstations you have to buy windows on ?
Better Iceland become the world's library than Vanuatuu, because that little island could just disappear in a typhoon and take all the servers and storage with it.
Well, Iceland has active vulcanoes, some which had recent, powerful eruptions. Perhaps not the best place after all ?

Hey, you can always run Wine or VMWare.

Gives you the feeling of running wintendo from time to time, to remind you never to do it

apple.com is very nice, imho. It is
Good looking (imho)
Light weight (for the times when you are not on broadband, support sites for instance is merely text)

It sell's Apple computers! (hihi)
