Firefox 2.0 Update To Remove Phishing Detection

TeacherOfHeroes Re:People on older distros (351 comments)

Firefox 3 relies on the Cairo (svg) and Pango (typesetting) libraries, which are included with and used by newer versions of the GTK (I thought it was >= 2.8, but meh). Especially when using older linux systems (like RHEL4) to which you do not have root access, trying to build all of the updated libraries in a little bottle just to run firefox 3 is a pretty tall order. IIRC, when I tried, I had to start at glibc and work my way up - I never did get it to work properly.

Firefox 2.0 Update To Remove Phishing Detection

TeacherOfHeroes Re:Will anyone notice? (351 comments)

I use neither firefox nor windows, so I don't know for sure, but wouldn't the automatic updater have upgraded most of those people to Firefox 3 when it was released?

If that is the case, then the only people impacted by this would be those who deliberately refused the upgrade.

Windows Drops Below 90% Market Share

90^2 is 8100 (and 10^2=100 for a total of 8200) - maybe the GP just got the 8 and 1 reversed

Greenpeace Slams Apple For Environmental Record

TeacherOfHeroes Re:Flawed study (271 comments)

As I understand it, these ratings are, in large part, a way to help environmentally conscious consumers buy green products. By not disclosing that information, they make this impossible for consumers to do accurately. Reducing their scores for not cooperating is about the only means they have to pressure the companies into being more consumer-frieldny in this matter. While it may be flawed as a study, it functions correctly as a guide to buying products you know to be environmentally-friendly.

Think if it a different way: If you showed up for a university exam or a job interview, and refused to disclose what you knew about the subject in question, wouldn't *you* expect to get low marks, too? If you in fact knew a great deal about the subject, you could claim that the exam/interview was a flawed study, but the fact of the matter is that you refused to participate, and in this case you don't get the benefit of the doubt.

Samsung Mass Produces Fast 256GB SSDs

TeacherOfHeroes Re:Fuzzy math (280 comments)

I think you may have the Giga/Gibi lables confused. Depending on your definition of Gigabyte, Gigabytes are either the same size or smaller than Gibibytes

A Gibibyte is 2^30 (1,073,741,824) bytes. This is the only definition that exists for this term.
A Gigabyte traditionally also means 2^30 bytes, however 'Giga' is actually a base-10 prefix for 1000^3 (as used in the metric system), and therefore has a second menaing of 1,000,000,000 bytes (slightly less than 2^30 bytes).

Hard drive makers were quick to jump on the fact that they could advertise their drives as larger than they were by exploiting this double definition. If anything, what we should want is for hard drives to actually by labeled in Gibibytes to remove the manufacturer's ability to short-change customers.

Since gigabytes are the same or smaller than gibibytes, claiming that it can hold 10 x 25 Gigabyte movies gives us no guarantee that it will be properly, non-deceptively labeled.

Samsung Mass Produces Fast 256GB SSDs

TeacherOfHeroes Re:Fuzzy math (280 comments)

This is somethat that a lot of people tend to overlook, either because they don't understand how a hard drive works, or because they don't stop and think about it. Loading programmes, especially ones which rely on libraries, translation files, multimedia, etc... at other locations on a disk would greatly slow down a HDD in comparison to an SSD.

Contrasted with SSDs, which are pretty much random access devices, in order to read each of those files from an HDD, there are basically 3 time factors to consider.

1. Seek time. The time it takes to move a reader head to a specific track (ring of data on a platter). Assuming that there is only this read taking place, you can pretty much assume that the reader head moves from its current location to the correct spot on the disk right away. Things are not always this pretty, though.

2. Rotation time. On average, you will have to wait half a rotation for the correct spot on the disk to spin around to the reader heads. There may be algorithms designed to mitigate this by reading even as it waits. In case the read is large enough to span a significant portion of the track, it can append that buffered data later, but I don't know if this is done or not.

3. Read time. This is the amount of time required to read the data off of a single track, and can take up to 1 rotation of the platter to complete.

So while the GP has a point in that people need to be careful about what kinds of statistics they believe, he/she glosses over the fact that reading a single piece of data with an HDD is hardly a random access, constant time operation (or linear time for n pieces of data).

City Sues To Prevent Linking To Its Website

TeacherOfHeroes Re:Did the editor read the last paragraph? (429 comments)

If /. wants to pontificate about censorship they should do it in the cause of a more upright citizen.

Isn't the whole point of free speech that people should be free to say what they'd like especially when others find it distastful or inappropriate?

Its not really freedom if you're only allowed to say tasteful things, is it?

Ubuntu To Pay for Upgrades To the Free Software User Experience

TeacherOfHeroes Re:Gnome + KDE (546 comments)

I disagree. I seriously hate KDE.

KDE is dysfunctional, overwhelms me with options, looks like shit (well, that can be themed, but...) and just generally sucks.

If Gnome had been chosen instead and as much time had been spent on polishing Gnome as Mandrake/Mandriva has spent on polishing KDE, we would not have this discussion.... Mandriva (i.e. Gmandriva) would already rule the desktop.

Sadly, I see more and more development time wasted on supporting / trying to polish KDE into something usable instead of just throwing the towel into the ring and going with Gnome.


Sorry if this offends your sensabilities, but I just couldn't resist, and I think that is pretty much sums up the silly debate between KDE and Gnome users who are both happy with their own choices.
