I would wholeheartedly recommend a Mac to any senior.
Agreed, but I say a Mac because using one is a more rewarding experience and the presentation is done in a very simple way. I think I read somewhere that the life expectancy for a Windows user is like 10 years less than a Mac/Linux user:-P
where does this thought come from. Shareholders elect the board members which includes Al Gore, the CEO of Google and Steve Jobs himself. Since the shareholders are electing some pretty innovative folks to the board, I hardly see how Jobs is solely responsible. Honestly, it was the shareholders who brought him back.
Motorola. Basically, Motorola hadn't reported the amount of devices that they had sold so they couldn't be broken out from the other category. Note the -20% growth in the other category. That is all Motorola too.
You claim that disk fragmentation decreased stability, but you didn't actually cite an example of decreased stability.
Read my full post and you will see where I note that fragmentation makes the disk work harder and increases heat which can shorten the life of the drive. Yes, I don't have a case study of fragmentation causing disk failure, but in the case of moving parts, it is pretty common knowledge that more movement and more heat are causes of failures.
10GB's of small files several of which get deleted was the source of the fragmentation. The quantity and the distance between files was the point, but your point is also valid. The condition this place was in was largely due to the fact that data was not removed per any normalize bahavior(no FIFO or LIFO). It was largely dependent on a several hundred humans hitting an accept button. Some humans were really good about it, others would add a month delay.
I've never heard of a fragmented drive affecting machine stability.
Hear it now. I use to work at a digital invoicing company which used ext2 on linux. We were seeing extremely slow reads and writes to the disk. Now, in this environment, we were writing upwards of 10 gigs of data a day(spread amongst thousands of files). We would also delete 9 gigs of that daily. Compound this behavior over a couple of years and we were left with a heavily fragmented disk. The solution was simple... we re-wrote all the data.
Fragmentation has nothing to do with data integrity which is the only thing that would affect stability.
Wrong again, fragmentation makes the disk have to work harder. Think about it... the disk could read 10 bytes incrementing a byte at a time or it could be required to skip 20 gigs to read each byte(this is an over-simplification). This will increase wear and tear on the moving parts as well as extra heat. So, extreme fragmentation will likely decrease the life of your disks.
What US Legislation? Cell Phones are not required to have GPS and since when did the US market drive cell phone innovation? Europe and Asia drive cell phone innovation. Just look at the companies: Nokia, LG, Samsung, Sony Erickson... Motorola use to be a player, but they hardly matter these days.
but the whole reason why cell phones have GPS is so that emergency services can find you with more to go on than "um..I'm by some trees, there's a kinda funny looking rock next to me..."
When did that become the point? I didn't buy my iPhone with GPS for that feature. In fact, I have never called 911 in my life. I bought my iPhone for location based apps/services. Like Google Earth, Google Maps, etc... etc... etc..
Well, I'm going to assume the ext2/3 drivers are not buggy and then ask, why not just STOP fscking it if it bothers you that much?
Because in the case of a crash(yes... servers crash in the real world. Power outages happen... retards accidentally unplug it...). When a server goes down, I need it back up extremely fast. My time is valuable... I don't have 2 hours to devote to micro-manage an fsck. And don't tell me you don't have to micro-manage it. In Solaris, it will try its best to fix it, but drop you into single user mode to force fix some errors.
So really, WHY is it running so often that it bothers you in the first place?
Because I use to maintain a few hundred machines. At that scale, something is always broken or ready to break.
it just doesn't matter THAT much for most applications
well... run an fsck against ext2 and ext3 and tell me it doesn't matter. For an admin, speed, reliability, recoverability... are all major concerns. On Solaris, I love ZFS because of the functionality like snapshots and exports. I also got burned by the IDE/100% CPU driver bug on Sparc hardware. Admins need to be aware of what they are running and what limitations exist. I honest don't give a damn about mp3 encoding speed, but the capabilities and maturity of a filesystem have to be considered.
Seriously... one of the nice things about Windows, OSX, Solaris is that they get a new filesystem once every 5-10 years. The safest thing to do for Linux is to be a generation behind. I would not run ext4 until btrfs came out. Why be the admin that gets screwed with early bugs and future incompatibilities...
Ok... after much reading. I can authoritatively say that we are living in a sandbox. And that the development of Java finally gives us a language in which to describe it.
Perhaps because:
A) They don't pay taxes
B) They don't own land
C) They don't have families
D) They don't have any interaction with most laws (from cars to copyright)...and so on...
Maybe we need a country and people that believe in statements like:
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the Pursuit of Happiness.
If you are looking for something fun... take in some old junk.
How about an older CPU and some memory. You would even bring a mouse and ask the class if anyone knows what it is. Someone will of course. ADD needs things to keep them interested. I would even take some pictures of a datacenter and explain that their are entire buildings full of nothing but computers.
Don't underestimate 4th graders. They use computers, they play games, and actually quite intelligent.
The problem is that there is no reason to assume that just because a machine is making a DNS query it intends opening a TCP connection to port 80 (or 443).
Most things that don't use HTTP are going to be saved in a config file somewhere or configured once. For instance, if you are going to use ftp, you will bookmark the ftp server. Same thing for IRC, usenet, SMTP, POP/IMAP. Basically, most DNS errors will be generated from web browsers since most people type in the address and everyone knows that end-users two finger type.
The people doing this had better have made sure that the machine serving these ads can cope with being bombarded with random IP traffic:)
I know you put a smiley, but non-port 80 traffic should never hit these 404 serving machines. It should be cut-off at a firewall. Even if it wasn't, this is a consumer service and I highly doubt that much random IP traffic will be generated that isn't HTTP. While we are on this subject, this could also give them places to expand to. Why not an Ad Serving FTP, SMTP, SSH, Telnet... servers that disconnects you after the ad. Brilliant!
Probably not fair to label the parent Flamebait. It is an honest observation and actually a good topic of discussion.
As a person who use to be into the DIY solutions... It just isn't worth it anymore. From 97-2006 I hosted my own domain, had an irc server for a few years, mail all through the years... you know... geek stuff. I was proud of every bit of it.
Unfortunately, I grew past that stage and went onto bigger and better things and didn't need to be bothered by the latest sendmail, apache, webmail exploit. Google Apps gives me the ability to offload that to Google and not have to worry about it any longer(although they don't offer an IRC Server yet).
As far as slashdot... I think the popularity of the site has changed the demography of its users. Slashdot users are not the small, proud group of nerds they once were.
Now, I whored out gmail for two reasons. 1. It works. 2. Some of us want to devote our time to other things.
So ignoring the most obvious free solution is a good idea. Google is popular for a reason. Setting up Google Apps takes about 10 minutes, you don't even need to host your domain(you can do it with just access to DNS) and it never goes down. Enabling POP/IMAP takes only a few minutes and you are done. The only reason not to use google apps is if you are paranoid about people looking at your emails. If that is the case then you should be setting up Postfix or Sendmail.
The average user is not going to know that they have been hijacked and they won't necessarily know which window is doing it. The clipboard hijacker could even wait until you copy a url before modifying it.

yup, very much about time. All of us sysadmins in Java shops have been hitting the 4 GB maximum for awhile. Java really does love the memory

because he is a producer of the film?
The last time this happened, it went from lush jungle to desert within 200 years, possibly within a human lifetime. Must have been quite a shock.

Which is why the title is misleading because it doesn't reflect the damage that ASFs do, but implies that MP3s are dangerous.
