For me it was just getting my head around it. It's logical.
You have ten fingers at your disposal. I used no typing tutors or books or classes.
First, get your pointer fingers on the home keys. F, and J. You'll notice those keys have raised bumps, nubs, or generally feel different than every other key in some way. Line up the rest of your fingers on the keys next to them. Pinkys on A and ":". Rest of your fingers on the keys in between. You'll have a G and H staring back at you.
Next, get a piece of paper. Look at the keys around those "home position" keys. Figure out what keys out of the keys that are left are closest to each finger. Obviously, you'll hit G with your left pointer finger and H with your right pointer finger. Y and U with your right pointer finger and so on. There is an optimal finger for each key starting from that home position. Your pinkies end up hitting lots of keys.
Once you figure out what keys go with what finger, Start out slow, cheating by looking and type out:
The quick brown fox jumped over the lazy red dog.
Do it again and again and again and again. At some point you'll stop looking.
After that, concentrate on making a letter appear on the screen at random. Try to hit the A without having to look. If you can't, look. Then do it again without looking. Eventually you'll be able to type like you would on a typewriter without having to look for keys. Slowly work in the rest of the keys.
Pitfalls to avoid:
Get used to using the opposite hand to hit the SHIFT key for the other hand.
Learn to use the number keys above your letters instead of the crutch that is the number pad. You'll be much faster if you don't have to move your hands from the home position to hit numbers.
Take your time and don't get discouraged. Every little victory in the form of memorizing where a new letter is without having to look keeps you going.
I'm doing about 90wpm now. A lot of that has to do with spending 10 years on IRC before finally walking away for good. IRC is a great way to get really fast at touch typing.
I think I pretty much summed up that I was familiar with the environment that I live on, and that I'm not "stupid". I don't think you are either. Someone new to FreeBSD has every right to think the way you do. I'm just too "oldschool" to do everything "correct". Neither one of us are right. I just have a system based on an old way of thinking that works for me and the businesses I support. Traditional UNIX is FUELED by elitism. It is sad, but true. Back in the "good ole days" of UNIX, that sadly I'm old enough to remember, RTFM was the way things were done. Everyone had an attitude problem big enough to push a barge up the mississippi. The BOFH mentality. I try to filter as much of that out as possible. The problem is.... IT WORKS. That elitism inspired the right people to "fuck off" and do better and inspired the "wrong people" to just fuck off completely. There was no room for amatuer hour at the levels I've been at. If you sucked, you had better adapt quickly or perish for the sake of the enterprise. People like me are now a dying breed. My attention to detail is razor sharp because of years of competing with conflicting points of view. I survive because I continue to fight. Guys like me don't fit in well with the fortune 500. I preach things that HR reps are scared of. And I'm DAMN lucky to have the clients I have. Because I KNOW damn well what I'm talking about. That is the only thing that saves me. I still get to have my pride. I still get a fraction of the 300k+ paycheck I used to get for about 3 times the work. But I don't have to change. And I know what I'm talking about.
I would appreciate pointers to articles that show companies making a migration from any operating system to any BSD varient
And many more to get done. I doubt I'm going to inspire anyone to write an article. I do contract security/admin for a handful of mom and pop ISP's and smaller webhosting providers. I set a bunch of them up with FreeBSD initially when I found ancient slackware or debian. If they needed a new machine for something, I'd use FreeBSD. After a while they started noticing the FreeBSD machines were no trouble. I had some standouts that run redhat with plesk, cpanel, hsphere, etc. environments. A lot of them are getting hacked because it's ancient redhat. I'm getting a ton of new customers that want FreeBSD because they have ancient redhat/slack/debian (mostly redhat with plesk) and want something not only more secure, but easier to secure and keep that way. I can't be the only guy that does what I do. Lets wait a few months and see what the netcraft numbers say. There has been a rash of website hackings lately (mostly brazilian groups) that target old redhat systems. A lot of these smaller companys are using redhat 6, 6.1, 7.2, etc and have a guy that was just smart enough to install it but had no idea how to update it. A lot of them don't want to pay for up2date. FreeBSD is supported by Plesk, so it's a natural choice for a lot of customers. Some customers are sick of paying for Plesk so I migrate them to webmin/virtualmin/usermin. I'm not sure how netcraft tallies their numbers, but about 15,000 websites that resolve to about 500 unique IP addresses are now hosted on FreeBSD instead of Linux. I mostly serve the lowest tier providers though. We are talking joes chicken shack (one location) and about a billion bored housewives with crafts businesses or people who sell on ebay exclusivly. It's not like the big boys are calling me. But the biggest boys are already running FreeBSD according to Netcraft.
I cvsup nightly because it really doesn't matter. That and a lot of these machines are commercial webhosting platforms. One very tiny nightly cvsup is going to take a lot less time than a weekly or monthly update. If it's done nightly, chances are that any security update I hear about from freebsd-security-announce is already there. Also more likely any port with a security problem is upgraded also. That's why I cvsup nightly. I admin 300+ machines that are all facing the world. On each network, I cvsup ONE machine, then push the packages out to the other machines in the farm. In keeping with my "hands off, zero administration" approach, I prefer using cron'd rsync to keep a package directory updated instead of using nfs which is sometimes thought of as an acronym for "NO FUCKING SECURITY". My scripts then install my pre-approved packages from the local package directories on each slave machine. Editing/etc/default/make.conf is of little concern to me because I know the meaning of every single line in the file as I've been using FreeBSD since version 2.1.7. I suppose I could copy it to/etc and only put the differences in there, but it's really not that big of a deal. Rc.conf is something I don't mess with though. I do edit the one in/etc and leave the one in/etc/defaults alone. FreeBSD is kinda how I pay for my car and my house and my food. But hey, thanks for the tips!
I'm humbled. I used ports forever, even dabbled with portupgrade on FreeBSD and still was of the opinion that Gentoo portage was "better". If anything, I'd say they are neck and neck now. VERY good article. From someone that has to manage a whole bunch of FreeBSD machines, this article hit the spot. Now I'll just add portsdb -Uu and pkgdb -F to my nightly cvsup cron job. If you take the time to set up your cvsup stuff in/etc/defaults/make.conf, updating your sources and ports is as easy as:
cd/usr/src make update
To translate for Gentoo users:
emerge -upD world becomes:
portversion -L "="
and emerge -uD world becomes:
portupgrade -arR
Oh, and etc-update has always been:
mergemaster
Though mergemaster does kinda suck until you get used to it. Not that etc-update is an e-ticket ride either.
Even if you have a bible, that is such a waste. It's much better to just wait a day (I used to wait two) and visit reality. The contrast can be startling. If you positively can not and will not wait a day, shrooms or great hydro can fill the gap nicely. It's not like it's a living hell.
If I were you, I'd take advantage of the glut of unemployed coders and have someone make you a web-based frontend to a perl or C based backend solution for this problem. Perl would probably work fine. It's kinda what it's designed for. Something like this would be pretty damn easy actually. Then you could/would have an application that does exactly what you want it to do, and the source to make modifications down the road if you need it.
If they didn't update red hat, what makes you think they will for FreeBSD?
They won't for FreeBSD. *I* will. That's part of the lovin' they get from me. For a fee much smaller than they'd pay to re-redhat their entire network and the fortune they'd pay to keep plesk updated, I move everything to something that is not only more stable and completely free as in beer, but easy as hell to keep updated. Have you ever had to admin FreeBSD? Handling the security end of things is so easy that I charge next to nothing (reletively speaking) to monitor their FreeBSD machines that I install and keep them patched and updated. I haven't had one hacked in 3 years. They get a managed solution for less money and heartache. I write elegant scripts to automatically update 300+ machines remotely when there is a security issue.:) It's neat how you can put the same webhosting customers back on the same hardware with FreeBSD instead of redhat and plesk and then another 30 percent more.
The way they combined the animation style with the computer generated car chase scenes in the "Initial D" animated series was simply stunning. They should win an award.
I do contract work. A HUGE bulk of it lately has been doing security audits on companys running old redhat, old plesk, or both that have been hacked by shit brazilian hacker groups like "Hidden Wrestle" and "Securinos". They hang out on irc.brasnet.org all day looking for webhosts using old plesk and old redhat. It's an awesome excuse to migrate people to FreeBSD and webmin. I've done quite a lot of that lately. They freak when they see the cost of the latest plesk and enterprise redhat. It makes selling them on FreeBSD and webmin/horde/squirrelmail/usermin/virtualmin/etc. very easy. So as long as people insist on installing 2 year old redhat and plesk 2.5 and never updating it, I'll have plenty of work removing eggdrop and psybnc from machines, and migrating people to FreeBSD. I'm starting to look at BMW's again.
Man, trying to keep up with all the things you know nothing about is hard but I'll try.
NVidia can't provide hardware interface specs for their boards because they don't own the rights to do so. That's why they go out of their friggin way to make the best 3d drivers and experience for games and graphics for linux out of the kindness of their hearts on their time on their dime. It's not like they are making money doing it. Me and some other guys started a petition a while back, and after about a year they started paying attention.
I wouldn't say NVidia services the market in a limited way given they walked away the hands down performance winner in at least this poorly conducted benchmark. There are plenty of people that trust and use their products. It has a lot to do with driver quality. Don't fall into the pathetic fanboy trap that a lot of people have and start predicting their demise. They are highly diversified. the NForce mobo chipsets alone have made them a fortune. It was pretty nice of them to release Linux drivers for those too. It's not like they had too. They also didn't really have to bother releasing AGP support for other peoples cards either.
If you'd do a little bit of research into how SCSI works, and how it is manufactured, you'd probably understand why it is priced the way it is. You'd probably eventually understand why it's the only choice in a number of situations. Lets see you put together a 60 drive rack mount EIDE raid 5 solution. For a home user? EIDE or SATA is probably going to be fine. Someone doing massive amounts of graphics processing and realtime video editing? The drives are definitely going to end up being a bottleneck if they aren't fast as hell. Transfer and seek time. Raid 10 with 15,000 rpm drives dangling off of 3 channels doing reads and writes fast enough to keep up with the rest of your system. A friggin boatload of cache with speculative read ahead caching. Godlike control over every switch and variable you need to maximise throughput based on the size of the files you are working on. Basically, things you can't commonly do well with any IDE raid solution at this point.
Ahhh, you obviously don't know about the smokers network. See, the smokers at a company hang out outside. Being a smoker crosses all departments and classes. You are privy to information in other departments. You have instant contacts in other departments that other people don't have. You end up having more friends outside your department and doing social things with more people outside your department than the non-smokers. In every company I've been in, the smokers end up forming an incrowd that slowly rises through the company.
Actually, I've never heard of raid 10 being anything other than a bunch of raid 1 pairs with a raid 0 striped across them. I've also never heard of a raid 50 being anything other than a bunch of raid 5's with a raid 0 striped across them. Raid 10's are very common for news and mailservers. Perhaps we just run in different circles? I'm betting a lot of people knew exactly what I was talking about.
:) rsync is exactly what I use at the enterprise level. We use rsync to keep the data mirrored on another machine "waiting in the wings" so to speak in case something bad happens. To be more specific, we have a main machine that is only on a private address. All changes are triple checked on it. The data then propogates out to slaves with round robin dns. We run a DLT stacker on the main machine. I keep forgetting that most people don't run *NIX on their workstations at home. I really don't worry too much about worms, trojans, etc. RAID is more than enough data integrity for me. Worst case scenerio, I lose both my drives when lighting strikes my box or a meteor hits it. Then I have something new to bitch about. Then I start over. Yanno, it might not be a bad idea to start burning some of my crap on cd's thinking about it.
Kinda. If you are talking about raid 4 then you have an actual physical parity disk. With raid 5 there is no actual "parity disk" per sey. That's where idea of a "floating parity disk" came from. All the disks share the parity. There are advantages to raid 4 performance wise, but there are serious issues with overall data integrity if the unspeakable happens. Other than netapp, I don't know of anyone using raid 4 on purpose anymore.
Actually, that sounds a lot like the frankenmess I have thrown together now.:) I'm using an oil cooler instead of a heater core, some unknown aquarium pump with nothing on it but chinese characters, black electrical taped copper tubing, a truly strange fitting system I came up with using true-value hardware store parts, and aquafina with a dash of zerex. Instead of running a reservoir, I have a ton of extra tubing because I was lazy. I got a used swiftech waterblock for 10 bucks from a bud. I just wish for something "cool" looking that fits inside the case. I've been doing a lot of LAN gaming, and I'm getting sick of having to declock my system and put the heatsink back on.
Yup. That's what I mean. My bad. I personally prefer raid 10 with scsi, and raid 1 with IDE. You can get raid5 controllers pretty cheap on ebay. The 3 channel AMI ultragt 436 runs about 100-150 bucks and absoluteliy smokes for scsi. I think what you meant by redundant storage with Raid5 was the "floating parity disk" and having some hotspares set up. If you are going to go all out, I'm a big fan of raid 50 over raid 5. It's significantly faster at only a slight loss of drive space and fits neaty between raid 5 and 10 regarding reliability. Raid 10 is definitely the way to go if you are super paranoid and can afford it.
I guess if you're going to overclock it, then you'd want it cooler.
Exactly. Being able to dissapate more heat faster means you can push the voltage higher on the cpu. The higher you can push the voltage setting, the more stable the processor is at high overclock. If you can keep it all running very cool, you can get some seriously astronomical overclocks. I'm destroying a stock athlon 3000+ with a 40 dollar chip and about 65 bucks worth of crap I threw together for watercooling. The 3000+ is 270 bucks. My setup is also completely silent.
http://www.water-cooling.com/ Water cooling obliterates air cooling. I used to run a thermaltake slk800 with a 120mm fan wired to it with an adapter. It pushed 80cfm and kept my seriously overclocked athlon tbred 1700+ running at 38c at idle, and never over 48c at full load. With water, I haven't seen 40c yet under extreme load. I idle at 33c. And I have a crappy thrown together setup right now. There are guys that have never seen 27c.

For me it was just getting my head around it. It's logical.
You have ten fingers at your disposal. I used no typing tutors or books or classes.
First, get your pointer fingers on the home keys. F, and J. You'll notice those keys have raised bumps, nubs, or generally feel different than every other key in some way. Line up the rest of your fingers on the keys next to them. Pinkys on A and ":". Rest of your fingers on the keys in between. You'll have a G and H staring back at you.
Next, get a piece of paper. Look at the keys around those "home position" keys. Figure out what keys out of the keys that are left are closest to each finger. Obviously, you'll hit G with your left pointer finger and H with your right pointer finger. Y and U with your right pointer finger and so on. There is an optimal finger for each key starting from that home position. Your pinkies end up hitting lots of keys.
Once you figure out what keys go with what finger,
Start out slow, cheating by looking and type out:
The quick brown fox jumped over the lazy red dog.
Do it again and again and again and again. At some point you'll stop looking.
After that, concentrate on making a letter appear on the screen at random. Try to hit the A without having to look. If you can't, look. Then do it again without looking. Eventually you'll be able to type like you would on a typewriter without having to look for keys. Slowly work in the rest of the keys.
Pitfalls to avoid:
Get used to using the opposite hand to hit the SHIFT key for the other hand.
Learn to use the number keys above your letters instead of the crutch that is the number pad. You'll be much faster if you don't have to move your hands from the home position to hit numbers.
Take your time and don't get discouraged. Every little victory in the form of memorizing where a new letter is without having to look keeps you going.

Kinda. If you are talking about raid 4 then you have an actual physical parity disk. With raid 5 there is no actual "parity disk" per sey. That's where idea of a "floating parity disk" came from. All the disks share the parity. There are advantages to raid 4 performance wise, but there are serious issues with overall data integrity if the unspeakable happens. Other than netapp, I don't know of anyone using raid 4 on purpose anymore.
Actually, that sounds a lot like the frankenmess I have thrown together now. :) I'm using an oil cooler instead of a heater core, some unknown aquarium pump with nothing on it but chinese characters, black electrical taped copper tubing, a truly strange fitting system I came up with using true-value hardware store parts, and aquafina with a dash of zerex. Instead of running a reservoir, I have a ton of extra tubing because I was lazy. I got a used swiftech waterblock for 10 bucks from a bud. I just wish for something "cool" looking that fits inside the case. I've been doing a lot of LAN gaming, and I'm getting sick of having to declock my system and put the heatsink back on.
Yup. That's what I mean. My bad. I personally prefer raid 10 with scsi, and raid 1 with IDE. You can get raid5 controllers pretty cheap on ebay. The 3 channel AMI ultragt 436 runs about 100-150 bucks and absoluteliy smokes for scsi. I think what you meant by redundant storage with Raid5 was the "floating parity disk" and having some hotspares set up. If you are going to go all out, I'm a big fan of raid 50 over raid 5. It's significantly faster at only a slight loss of drive space and fits neaty between raid 5 and 10 regarding reliability. Raid 10 is definitely the way to go if you are super paranoid and can afford it.
I guess if you're going to overclock it, then you'd want it cooler.
Exactly. Being able to dissapate more heat faster means you can push the voltage higher on the cpu. The higher you can push the voltage setting, the more stable the processor is at high overclock. If you can keep it all running very cool, you can get some seriously astronomical overclocks. I'm destroying a stock athlon 3000+ with a 40 dollar chip and about 65 bucks worth of crap I threw together for watercooling. The 3000+ is 270 bucks. My setup is also completely silent.

Water cooling obliterates air cooling. I used to run a thermaltake slk800 with a 120mm fan wired to it with an adapter. It pushed 80cfm and kept my seriously overclocked athlon tbred 1700+ running at 38c at idle, and never over 48c at full load. With water, I haven't seen 40c yet under extreme load. I idle at 33c. And I have a crappy thrown together setup right now. There are guys that have never seen 27c.
The Ultimate Waterblock
Ultimate Pump
Ultimate Radiator
Two of these to cool the radiator at only 30db
Round it out with a Cool Reservoir and some tubing. Maybe toss in a GPU cooler. Plenty of pump to support it.
