I love how 1 MB of RAM is 1048576 bytes but 1 MB of storage is now 1000000 bytes of storage

Makes perfect sense. RAM is addressed with a N address lines, giving access to 2^N cells, so base 2 makes sense. For everything else, base 10 makes more sense, especially when you're talking about speeds.

simply because the hard-drive industry decided that they could make more money by using the same term

Really... You do realize that disk sectors, file systems, etc. are all Base-2? Base-10 makes no sense whatsoever. In fact, there is a movement back to base-2 for storage sizes as the industry moves away from magnetic media to memory based storage (SSD).

I would argue that using Base-2 vs Base-10 for CPU speed is irrelevant. CPU speed is only useful when comparing CPUs that have the same architecture and are in the same family. Even then, people only look at which one has the higher number. If it was a useful indicator of processing power, then we wouldn't use CPU benchmark applications to compare between Intel and AMD CPUs or between different Intel CPUs, etc.

They didn't make more money because everybody was doing this.

If you take a chocolate bar and make it 10% smaller but charge the same price then your margins and profits go up. That's what the hard-drive manufacturers did by simply changing the definition of MB. Granted, it was a one time thing. But they did get a nice surge in profits around the time that they made the changeover.

Just because you don't like the term doesn't make it wrong. Highjacking SI prefixes and changing their meaning is wrong and has led to countless problems.

And historical meanings shouldn't be changed simply so that marketing speak can be used to sell less at the same price.

I love how 1 MB of RAM is 1048576 bytes but 1 MB of storage is now 1000000 bytes of storage, simply because the hard-drive industry decided that they could make more money by using the same term, change the historical meaning in the computing industry from base-2 to base-10 (essentially downsizing the actual storage), and charging the same amount.

Either convert totally to GiB, MiB, etc. for everything computer related or stick with the old convention. It's when you are mixing the two in a particular context (i.e. computers) where you run into problems.

It is interesting that Google is making 75% of mobile ad revenue on the Apple platform ($9 billion) vs Android ($3 billion).

I wonder if this is because advertisers are paying more for ads on the Apple platform or if its because people who have Android phones are not using the smart features as much as Apple users. It's likely a bit of both.

The Amiga Workbench was multitasking - the first of its kind for "microcomputers" and it was the bread and butter of airport displays, sports announcers annotating where basketball or football players were moving on the field, and real-time "video toaster" displays for TWO DECADES after.

It was only in the late 2008-9/2010+ timeframe that Windows replaced Amiga displays for those things for realtime video annotations.

So yes, the Amiga did it first better. (Grandparent was right)
The Amiga did it for longer than anyone (sorry, Parent)

So sorry the mods are like 15-20 years old and are bored by history and facts.


It was outclassed even at the time it was being used for Babalon 5 by Pentium PCs and Macs. Amigas were only used for the first season...

I interviewed with SpaceX for a senior-level software position last year, and was offered the job but turned it down on logistical grounds.

I did indeed have to take the tests mentioned here, and did have to interview with Musk himself as the final step. However, he did not ask me this brain teaser question. In fact, he specifically said he doesn't ask brain teaser questions because they are dumb.

Nor would he likely ask such a well-known and old brain teaser anyway. This seems like one of those things erroneously attributed to "Bill Gates" over the past 20 years because he is famous and smart, and fits people's preconceptions.

This seems like a question that Musk may have asked one person one time and it became part of his story.

My Dad used to ask us kids stupid brain teasers like these. Every time we would give him the answer while rolling our eyes. Maybe he was getting us ready for a job at SpaceX. (grin)

That said, I use PuTTY when I find myself stuck with a 'doze box (usually when having to show a 'doze user something on a *nix box from his machine), or when I find myself in a datacenter with only a shitty old laptop and no other useful means of getting some RS-232 love (because let's face it, HyperTerminal sucks donkey balls).

I use a free program called mRemote v1.50 as it integrates Putty, RDP, VNC, Citrix, etc. into one console. It's a good tool as you can organize your connections using folders. As a network architect, it's nice to be able to connect to network devices by site. It has a few bugs, such as screwing up the sort order, but nothing major.

There is a newer version out called mRemoteNG 1.72. The last update was from the end of 2013 and it looks like the project is on hold for whatever reason.

It does what I need it to do and that's all I ask of any tool...

If it sounds too good to be true, then it probably is. All that talk about pirates getting free Windows 10 upgrades? Not happening.

Since when it is "good" to reward pirates, and to who (other than pirates!) it sounded "good"?

The Security community, maybe... Not all Pirates are smart Pirates. Some end up getting scurvy (trojans, spyware, etc) as a result of their pirating ways.

So, it's our fault that the Russians can't successfully launch a Russian rocket from a Russian launch site?

Interesting theory, that.

It's rocket science....

It's possible that they aren't able to get certain parts from their standard outside supplier and are forced to use local, Chinese, or black market parts due to the embargo. All you need is one part that isn't manufactured to the right quality or specification...

No, just no....

Store the documents in their original format.

There are many possible reasons why you shouldn't mess with the originals such as formatting, legal implications, loss of content because one format supports stuff that the other doesn't, etc.

The only way that I could see this working is if you converted everything to an open format but kept copies of the originals and linked to them. But if the plan is to dump the original documents, then it just isn't worth it....

Many if not all of my fellow musician friends actually stop being such fucking snobs as they mature and realize just how well conceived a lot of pop music is.

i do not think that word means what you think it means...

Most Pop music, music on the top 40, is very formulaic and overly processed. I agree that some of it is actually produced well and will a lot of talent. But those tend to be few and far between in the top 40.

Comment: Re:Not Wireless (Score 1) 75

This is not exactly wireless... It is not "hard wired' in that you don't plug in a cable. The technology uses a system of electric strips of alternating polarity and a pattern of contact pickups on the device to connect to the strips. It is cool, and should be much better than wireless in terms of efficiency.

Exactly. This is a wired technology. The device needs to make electrical contact with the charging pad strips. Just because it doesn't require a traditional cable or plug doesn't change that fact. The open dots alliance page actually refers to it as "wire-free" technology, referring to the fact that you don't need a cable. The article writers are misunderstanding the technology and substituting wireless for cable free.

It would be interesting to see just how this technology works. After all, you won't be able to just toss a device on it. It looks like you will have to place it. Also, you won't be able to place devices in different orientations unless they are connected to differing circuits as the +/- would be reversed for one of them.

Finally, since these are electrical contacts, they will likely be subject to wear, breakage, corrosion, etc.

I agree. There is a distinct lack of discussion that outlines where Hadoop shines versus a RDBMS and these other tools. I did some reading and it seems like a database system does better with data that is organized and has a distinct relationship between data sets. Hadoop and parallel processing seems to work better for data that is highly unstructured and for which you need to delve deeply to find relationships and create adhoc reports.

Some have mentioned that one of the reasons for interest in Hadoops decline is that it is expensive. There are always newer tools being released that may cost less just to gain market share. The question is, as always, are they actually better products?

I also agree that different problems require different solutions. Unless you are taking specifics, it becomes very difficult to produce a valid debate over the technology that would produce what is required. It's like arguing the merits of MS Excel vs. MySQL without knowing what the requirements are.

I very rarely complain that a story doesn't belong on Slashdot, but this time I will, because this is probably the least Slashdot-worthy story I've seen yet.

This is not news for nerds. This does not matter.

This could be worth of Slashdot if were were discussing the science, the need for proper scientific method, etc. But , much like sports reporters, a lot of people are blowing by this because the bias is that sports and science do not mix.

- It's interesting that the scientific firm used to back up the findings of the report once produced reports that second hand smoke didn't cause cancer
- It's interesting that the report relies on the Refs remembering the starting PSI values. We know just how unreliable memory is
