9 + 1 Ways ISPs Screw You Over

by Jett on Nov.18, 2009, under Computers, Internet, Technology

Happened across an interesting / simple explanation for those who don’t know how ISPs screw their customers, and thought I would add another way ISPs screw over their customers.

You can read the first 9 ways here: 9 Ways ISPs Screw You Over.

10.  ISPs advertise speeds in a way that only people who have an understanding of how data is stored can translate.  For example, lets say you pay for a “10 meg” connection, thats not actually 10 Megabytes per second you’re capable of, its actually 10 Megabits.  Now, there’s quite the difference between Megabits and Megabits, but not so much a difference in the acronyms.  MBps is for Megabytes and Mbps is for Megabits.  The real issue here is if you pay for a 10 Megabit per second connection, your maximum transfer rate is only going to be 1.25 Megabytes per second (there are 8 bits in a byte).  Thats also theoretical, you can very rarely actually achieve the theoretical bandwidth provided by your ISP, unless you’re trying to load their homepage or hit a url that they detect doesn’t exist and throw you a page full of ads.

I’ve been a long supporter of transparency from ISPs, but we’re likely never to see that up here in Canada – at least not until the CRTC cracks down and decides we, the consumers, need some competition and not more monopolies.

Sun buys MySQL, Oracle buys Sun…

by Jett on Apr.22, 2009, under Computers, Servers, Unix

So, big news of the week, Oracle just bought Sun Microsystems for some ridiculous amount of money ($7.4 billion in cash).  Aside from the obvious moanings of how I wish I had $7.4 billion in cash just sitting around so I can buy up companies like playing monopoly, this deal has me (and likely a number of other people) wondering about the future of MySQL now that its going to be owned by Oracle.

I’ve been reading up on the topic a lot, and it seems as though no one’s really talking about whats going to happen with Sun’s newest acquisition.  I can’t say I’m not just a little concerned, since all of our work here at MRX is powered by MySQL databases.  Thats not to say I’m afriad of Oracle, just its both expensive (as in not free) and complex.  I’d argue, so complex that not many people out there who know Oracle are looking for work.

One interesting point I did find when reading up on the topic that I didn’t really know, is that Oracle does own a number of other database systems including TimesTen, Berkeley DB open source, as well as InnoDB.  However, none of these directly competes with Oracle, whereas MySQL does.  So, the question is, do they monitize MySQL to a lesser degree than Oracle (while maintaining some form of stripped down free version), do they drop MySQL alltogether and provide some form of migration path to Oracle 11g, or do they simply let both co-exist and continue monitizing Oracle.

If I had to guess, I’d say they will likely monitize MySQL to a lesser degree than Oracle, probably in the form of support contracts mostly, and still continue to provide a free open source version of MySQL.  Obviously they would charge for any new features they decide to add to MySQL along the way.  Probably very similar to Redhat Enterprise’s business model – seems to be successful for them.

Ubuntu Jaunty Jackalope

by Jett on Apr.21, 2009, under Computers, Servers, Unix

So, I just upgraded to Ubuntu Jaunty on two of my VMs here at the office.  I know its not set to come out in a final release for a few days, however, we’re in the process of migrating to a fully virtualized system, and unfortunately Intrepid has some issues with iSCSI connections.  Namely if you try and shut down the machine, it’ll hang because it tries to disconnect the drive before its unmounted and then just throws errors.

Anyway, as per usual, the upgrades went more or less flawlessly – minus a few symbolic links that needed to be re-created.  Since I don’t have GUIs on these machines (waste of resources on servers if you ask me), a quick:

sudo apt-get update
sudo apt-get install update-manager-core
sudo do-release-upgrade -d

And about half an hour later and I was all upgraded.  No more iSCSI disconnection problems, and one new feature I’ve found that actually changed my whole workflow when it comes to servers.  That being the inclusion of screen-profiles, a sort of profile manager for screen allowing you to create default screens that open when you log in, as well as status bars, clocks and notifiers.  If you haven’t heard of it, I’d highly recommend you check it out.

Microsoft ads… someone’s missing the boat

by Jett on Apr.17, 2009, under Apple, Computers

Okay, so I’ve seen a number of ads promoting both Vista and Low-cost PCs coming out of Redmond recently.  Not that I watch much TV, so either they’re just being targeted to the TV I do watch, or they’re on all the time, all over the place. Now that said, I am a Apple fanboy, I’ll admit it, I love most Apple products, that said though, I am willing to criticize them where I believe they’ve missed the boat (ahhmm, AppleTV and Codecs).

In any case, there are two types of ads I’ve seen, one that features children using Vista to do fun stuff with photos.  Okay, they’re cute, and Vista works for children, I get it.  Thing they forget to mention is that those computers had better be locked down and never connected to the internet, unless of course you want to be exposing your 8 year old child to random porn popups while they’re looking at photos of their dogs.  The other type being the ones where people are sent out looking for low price laptops and pass over Macs because they’re either too “cool” or too “expensive”.  Both of which are silly propositions to make, since if you were to compare hardware in any recent apple laptop to an equivalent Dell or HP, you’ll come out at about the same price (last time I did it, I think I was $50 in).

Now again, I’d like to caution that I really enjoy Apple’s – I work on one all day – that said, I grew up on PCs and when I finally did make the switch after working at Barking Dog Studios, I decided that the platform fit me much better.  What I’m really trying to say is that someone at Microsoft should take a good hard look at your advertising campaign, and perhaps give it a once-over to remove all the BS you’re pushing on people.  Or better yet, instead of spending millions on an advertising campaign, build a product that works and works well that people will want to spend exhorbitant amounts of money on.

A Brief History of CPUs: 31 Awesome Years of x86 | Maximum PC

by Jett on Apr.14, 2009, under Computers

Fun article for a bit of Tuesday morning nostalgia.  My personal favorite quote in the whole article:

In the beginning, Intel created the 8086 and its first 16-bit microprocessor.
And Intel said, Let there be x86: and there was x86.
And Intel saw the x86, that it was good.

Its amazing to think that in only 31 years we have come so far as a technologically advanced species.  Just stop to think for a minute, 30 years ago, not a single person in the world could even begin to imagine the depth and breadth of information we have at our fingertips, real-time communication without boundaries or borders.

Always amazes me to some extent.  Anyway, here’s the original article if anyone’s interested.

Bluetooth 3.0 prepped for launch on April 21 – Ars Technica

by Jett on Apr.13, 2009, under Computers

Interesting article on Bluetooth 3.0, I haven’t really been following it – however, it seems as though somehow Bluetooth 3.0 are going to be creating temporary (hopefully secure) wireless networks for transmitting data.

Bluetooth 3.0 prepped for launch on April 21 – Ars Technica.

I’m curious though, how do they intend on dealing with frequency crossover from actual wifi networks.  In my experience, bluetooth networks are horribly prone to interferance and hopefully that doesn’t translate to the new specification.

Converting Raid-1 to Raid-5

by Jett on Jul.25, 2008, under Computers, Servers, Unix

So, I happened across this article today, written by a Scott Wallace, I’ve copied the text here in case his site goes down for whatever reason. Note, I haven’t tried this as of yet, but in the future when I fill up my drives, I’ll likely be able to just buy another 500 gig drive and convert my raid-1 array to a raid-5 array instead of having to buy another 3 whole drives.

Enable/Disable Ubuntu Remote Desktop from the Command Line

by Jett on Jul.23, 2008, under Computers, Servers, Unix

Further to my previous postings about Ubuntu and VNC, which seems to have been the most popular page on my blog for a while, I happened across this post from Sam Lesher this morning on how to enable Ubuntu’s built-in remote desktop from the command line. The built-in remote desktop uses VNC, and so kind of eliminates the need for any form of VNC Server setup.

Sam Lesher » Ubuntu 7.04 – Enable/Disable Remote Desktop from the Command Line

To enable remote desktop from the command line, issue this command:

$ gconftool-2 -s -t bool /desktop/gnome/remote_access/enabled true

To disable remote desktop from the command line, issue this command:

$ gconftool-2 -s -t bool /desktop/gnome/remote_access/enabled false

Unfortunately, this only works if you have previously configured remote desktop with a password, which would in theory require physical access to the machine.  That being said though, I want to set it up remotely, and so to add to Sam’s guide, I’d like to add that you can X-Forward a gnome session through SSH which will allow you to change this option.  I’m working on a how-to which I will post shortly.

A salut to an old friend

by Jett on Jul.21, 2008, under Computers, Servers

Well, its been a long time coming, but tank has finally died. For those of you who no not its saga and history, you are sorely missing out. Though, as with any computer system, especially one containing my whole television collection as well as all my backups, it will rise again. Not after some serious modification though.

As it would appear, the motherboard finally died, the system simply refused to boot if any SATA drive was plugged into it – obviously a problem. I went out to the local computer shop and picked up a new motherboard, processor and ram. Specially, I got myself an ASUS M3N78-EMH HDMI motherboard, and I know, I have absolutely no use for an HDMI motherboard, but it fullfilled my main requirements of being under $100 and having more than 4 sata ports (specifically it has 6), bringing my total available sata connections up to 8 (I have a PCI card).

So, I get it all home, rip apart tank – dust off as much as I possibly can, and I go to town unpacking, reconfiguring the case and generally getting everything set up. So, I’m sitting there going through the checklist, processor mounted… check, processor fan mounted… check, ram mounted… check, hard drives plugged in… check, *CRAP*… well, it would appear my 4 year old Thermaltake power-supply is only a 20-pin, and this new motherboard is a 24-pin. Now this is at 9:30pm on a Sunday night… no computer supply shops are open.

So, just a quick note to anyone looking to upgrade, check your freaking PSU before you buy a new motherboard!
