Given that the Mac community are more concerned over Photoshop than databases its not really suprising that they haven't concentrated massively on transactionally written files (lots of small writes) and may have chosen to focus on optimizing the writing of big files and the maths and graphics processing that goes with graphics work.
Sure its interesting to compare the Mac OSX with Linux on the same tin and see where one is faster than the other, and sure it might mean that Mac OSX Intel is going to be poor at running MySQL too....
But in terms of a fair evaluation and "no more mysteries", what they haven't covered is why transitions in the GUI are so much smoother than those achieved by Linux or Windows...
And this is the problem with the way the US legal system is going. Murder by a juvenille becomes a death penalty offence, and hey look another felony should have them tried as an adult and another.... etc etc etc until we have 12 year olds being tried for fraud because they lied to their parents about tidying their room to get their pocket money.
Its a more fundamental question than small potatoes, its about whether its right to EVER try juvenilles as adults.
They are also XML files, which can be understandable in plaintext.
This is the single biggest myth about XML, the idea that its "understandable" in vi. XML documents can be insanely complicated beasts, try looking at a BPEL document for a great example. XML documents can also have binary in them (for instance images) and of course if you don't have the schema to go with the document then you don't know the constraints on the structure and order of elements. MS could use (and I think does) XML to describe their documents, if however they keep the schema secret, use binary imports or just create massively complex multi-namespace documents then it will still be as closed as ever.
Always can theoretically get cracked. This doesn't mean that they always HAVE been cracked.
With DRM, the guy gets to take the "sign" home for a few weeks at a time, until he can manage to crack it -- and once he does, you don't have any clue that he's done it.
Which is why we should expect two tier DRM to become a standard pretty soon, first level to "protect", second level to "inform", so sure you can crack the protection, but it then sends a message to inform. Of course some people will be able to detect this, but how many? Next time you use MS Media Player and it "connects to server" how can you be sure its not informing MS of violations?
And before anyone bleats about "civil rights", this is the same as those car trackers that get activated when a car is stolen. If you don't steal something then it doesn't inform, if you break the seal it then informs.
People who see digital audio as a free lunch are the people ensuring that the goverment restricts liberties for everyone.
With everyone chasing multi-core rather than clock-rate this isn't really a suprise. If you want to run 4 cores on one die you clearly need to reduce the power consumption of each of those cores over what is done today.
It clearly helps with laptops, which of course will be multi-core themselves in a year or so.
What an odd day it will be when I start ordering either a "2-way" or "4-way" laptop.
The PDA will integrate all types of communications including voice, data and web
Riiight, so its sort of a SMARTPHONE then? Sure PDAs could be a threat, but its probably worth focusing more on something that everyone already has and which is has all this functionality already, as well as a digital camera etc.... the ubiquitous mobile phone.
Developing, and then requiring, a "secure" PDA for all your people and then being "suprised" when information leaks via their mobile phone with the 1GB Flashcard, 2 Mega-pixel camera and Broadband 3G connection doesn't sound like a plan for tomorrow.
I put my aged PII 400MHz home computer over to Linux a few years ago (well 2002 actually) and since then my Wife has suffered not a single case of having to reboot using the plug-socket, not a single crash and not a single failed application.
Until she got her iPod... so now we are buying a new PC, just so she doesn't have to use my work machine for iTunes.
My mother had an horrific attack of the virii which has meant I had to do a complete re-install of windows, and I've lobbed SUSE onto the other partition to help the recovery next time. My mother has elected to use SUSE to access the internet, and just go into Windows when she has to use the software from work.
My wife does email, internet, work processing and accounts, pretty much the same as my mother. BOTH have faired perfectly well with Linux (SUSE), with less hassle to me than on Windows.
And here is the kicker... installing Windows on a SATA drive was a pain in the arse, my mothers machine having no floppy drive and Windows not being able to detect the SATA (even in an SP2 install) SUSE 9.3.... had no issues and went straight on.
I couldn't WORK on Linux yet... but for the majority of INTERNET users who just want EMAIL, a browser and OpenOffice.... it really doesn't matter.
It is fairly obvious that exposure to sexually explicit material, violant video games, horror movies and some of the kind of lyrics in rock music will affect people, especially young people who are still developing their brains and the bits that help them control this stuff.
Of course the stats are WAY down on the victorian era where child prostitution was common and violence against children and by children was an everyday occurence.
You might as well say that all this new information is leading to less world wars.
Back in the "old days" it was the Waltz, then there was the Tango, the Charleston and then...
1950s OH MY GOD THE WORLD IS OVER, Rock and Roll... our children are being corrupted 1960s OH MY GOD, ELVIS is such a good boy, but those BEATLES 1970s TV is KILLING my Children 1980s HORROR MOVIES are KILLING my Children 1990s NIVARNA are forcing Children to top themselves
And of course now its Video Games which are forcing Children into a life of violence.
This is just another great "Aunt Sally" for politicians and "academics" to debate and get money from. If it wasn't this they'd be battering on at Cartoons for glorifying violence (there is nothing in Doom III worse than the violence of Tom and Jerry or Roadrunner). The young are ALWAYS being corrupted in the minds of the elders, and what corrupted them in their youth is now seen as innocent.
And have you noticed... its always the over 40s who start wars... something must be making them do it.... I blame mugs of hot chocolate.
And lets not forget when Marge banned "Itchy and Scratchy"
Now I like SVG, but this is like having the Microsoft PDC talk about the future of Windows... its hardly a balanced view on the future. Its like a Windows v Linux review funded by Microsoft.
Don't get me wrong its interesting stuff... but in general the view here is from the position of SVG being the only answer, and that is currently far from being a certainty.
Why aren't we all HIV positive yet? The disease is still very confined. Back in the 1980s AIDS was going to break out "real soon now". 20 years on the only time AIDS deaths increase is when a new disease is reclassified as AIDS related & we start looking for HIV in conjunction with it...
Education, Condoms, Blood testing. One of the reasons that AIDS hasn't exploded in the West is that people headed the warnings and started using Condoms. There are programmes with drug addicts to ensure they get clean needles, education of teenagers in using condoms etc etc
Why is the disease profile so very different in third world countries?
First culprit has to be the wonderful folks in the Vatican who forbid the use of Condoms and have a large degree of control in the 3rd World. The US Goverment is beginning to match the Vatican by trying to promote celibacy as a primary driver rather than tackling the problem in situ with a piece of latex.
Second up of course is plain poverty and lack of education.
I just meant to present the observation that from a pure physical standpoint, force is the only way to ensure certain actions are stopped
Which of course explains why you only listen to judges because of the guns.
Force can only reliably be used to prevent someone from doing something (and by 'something' I mean something over which the subject has direct physical control)
Again completely contradictory to what you said previously as clearly the judiciary has no direct physical control over either the army or you.
It works in Sport as you can choose to do specific things, for instance during the BBCs coverage of Wimbledon you had a choice of 6 different matches, and a similar choice at the Open. On Sky Sports you get a choice of several different camera angles, touchline, behind the goal, focused on a player etc, as well as several audio lines. Its interesting stuff and is used a bit, when it will really come of age is when its properly PVR'ed and you can cut your own replay scene of what ever you want and from the various feeds available.
You could also imagine "24" being done as a single broadcast with those little windows as seperate feeds... so to be really hard-core you could just follow one character and try and work out WTF is happening.
People in the US in particular seem to forget that the only real way to enforce anything is with force.
Errr its a nice attempt at a troll but you let yourself down here... the US is the FIRST nation to enforce by force... and the last to resort to justice.
And of course the last to learn that actually it doesn't work.
"You can lead a horse to water but you can't make it drink"
Its a little to scary to think that this isn't a troll and there are people this moronic who might be allowed to vote.
280,000 records, even for MySQL, isn't that much and indicates that performance is being driven down either by tiny hardware or more likely...
1) Badly optimised queries 2) Poor index selection and maintainance 3) Generally poor schema design
It might also be that queries should be cross table with sub-queries(not a MySQL strong point).
9/10 poor database performance is due to bad database design.
Why do it yourself?

DHTML Utopia
·
· Score: 4, Interesting
The challenge with Ajax, and complex DHTML is that a slight error produces big problems. Its a shame that the book doesn't look at the tooling approaches for instance the Ajax plug-in that Sun have released (via Open Source). DHTML and these active elements can be great, but as a practice I'd be more inclined to have a few people invest time in developing components that the majority of people can use, rather than having lots of people trying to understand the complexities, and buggering it up.
Interesting technology, but too easy to use REALLY badly. It would have been nice if the the book had covered how to build SOLUTIONS using DHTML, rather than focusing on how an individual can use it.
In it, he argues that in ten years the desktop OS will become obsolete in favor of a Web based one, and that content on the web will be automatically customized according to the device being used to access it (PDA, smartphone,etc).
Of course it will, just like there is only a market for 4 computers worldwide.
So we will all have smartphones with the power of today's desktops, and desktops with the power of today's supercomputers... but will just use them as a web-browser.
Some people are thick about the future, and those who repeat that the future will be the mistaken predictions of the past (Network Computers anyone?) wins a double muppet award.
Now the idea that a users "context" will follow them around independent of their own device is interesting, and more complex, than having a "big central server" solution and also means that it can adapt and add services from the user to the network.
But that sort of idea would require imagination rather than reading a Larry Ellison speech from the 90s on the web.
The power of computers keeps going up, a key question is how to harness that computational power, not to limit it to rendering pixels.
The finance industry does the most of EVERYTHING in the IT industry. The most Linux, the most Windows, the most COBOL etc... what the IT sector in finance REALLY excels at however is doing "cool stuff" with new technology....
When Linux really gets big is when those with more concerns buy into it... people in Manufacturing for instance, or in supply chains. Paid less, but normally with a better understanding of what it takes to build a system that lasts 20 years.
Linux is definately making it in those sectors, and that is better news IMO than the Finance sector.

It's not like they murdered someone

I just used MD5 as my encryption mechanism and the files will NEVER be recovered.
This "joke" such as it is was based on a real world experience where the "smart" IT chap at a company I helped had in his words...
"Tried a number of different compression and encryption approaches and MD5 consistently gave the smallest files"
I asked if they had ever done a recovery, and strangely they had not... it was fun watching them try.
