He's loading the page off a local drive. Use iCab to grab a quick mirror of the site to your local machine, then try it.. If IE on your g4 is still taking 10-20 seconds, you better find a new browser or return the machine to Apple!!
For a quick comparison.. iCab loads and renders the main/. page in under 3 seconds on my little G3/400 PowerBook (bronze w/OS 9.1, 384MB RAM, and 100baseT).. For reference: Netscape Communicator 4.75 takes about 2 seconds, and IE 5.0 takes between 2 and 3 seconds..
For this test, I took a 370kb page from Slashdot page. I saved the page out, rather than use it on the site, since comments could be added on the site which would skew the results.
Slashdot uses a lot of tables on the pages which can take a while to render, so what better test for a browser. Obviously this is a pretty extreme test as most pages are nowhere near as big.

WTF!!! 34 seconds to render/.? iCab on my mac is probably the slowest rendering browser out there right now (on a fat pipe, on a modem it rocks) and it renders the main page almost instantly! Please tell me this is simply a function of the low cost hardware that was used.. If not, I'll stick to OS X.. What am I talking about?, I'll stick to it anyway, but I'll feel bad for all you linux users out there..
How about SUN (a slick client os to compliment solaris on the servers)? or Apple (Mac OS X still needs some help)? or Dell (help grease the wheels between them and MS)? or maybe SONY (combine with the PS2 and you've got one slick little machine)?..
Dresses won't necessarily stop anything.. They'll just increase the applications from Scottish programmers. Seriously, dresses could be very comfortable..
Yep! And I'm still wondering why the school decided to upgrade the 486 machines in my lab to PIII 800's (the data streams in at one rate and the IBM Aptiva's handled it perfectly).. It all comes down to Marketing! If you're going to show off the lab to perspective students, you need new hardware.. Dumb!
Hey guys! There are a lot of people throughout the world trying to model combustion with the goal of improved efficiency.. Madnia at SUNY UB is pretty good (a little close-minded) but he's not the only guy out there this sort of work...
For those who haven't read much about CFD (Computational Fluid Dynamics) here's a little overview.. DNS (Direct Numerical Simulation) solves the equations of motion for a flow to obtain information for all the scales (wavenumber information).. The problems with DNS include restrictions on Reynolds number, limited run time (very few statistically independent samples), and domain size. I believe that currently the largest DNS that has been performed was on a 1024^3 element grid.. Unfortunately, it still really isn't fine enough to deal with a Reynolds number beyond a few hundred (many practical flows have Re #'s ~1e6+).. To model higher Reynolds number flows many researchers have moved to LES (Large Eddy Simulation) type approaches, where the equations are solved directly for scales above a certain range, and the subgrid scales are handled using a variety of models. LES has a handful of problems too.. The big problem when using LES for combustion work is that a large percentage of the mixing that these researchers need to manipulate in order to improve their efficiency occurs in the subgrid scales that they're modelling...
but FACE IT, who has a 20 gig drive in their laptop?
I do! As does the guy in the office next door, and the one down the hall, and the two upstairs, and Oh wait... The guy on the other side of the room has a 30GB drive in his.. 20GB drives for notebooks are pretty cheap, and the performance increase over a 1-2 year old 4-6 GB drive is phenomenal..
Sounds pretty slick. I just downloaded the script and took a look.. I'd be curious to see the results from your GPS enabled version.. Is there a way to measure the signal strength? I might be nice to record signal strength and location simultaneously.. With this info at a few points (interferance/reflections from buildings could make things a little tricky) you should be able to solve for the location of the hub/base station and then determine an optimal location to access said network (a park bench, cafe/coffee shop table, etc.)..
The DVD Player included with Mac OS 8.6 took advantage of the Hardware decoder. The versions of the DVD player that ship with Mac OS 9+ are all software based. This sucks because my little PBG3 used to be able to display a movie without touching the cpu.. Battery life has dropped, and the playback is not as smooth..
won't buy into Apple's mostly-proprietary hardware anyway
I'm really tired of comments like this.. As far as I can tell, the only proprietary ports on the iBook are the A/V port, the airport card slot, and the power adapter port.. USB, FireWire, ethernet, modem, and video out ports are pretty standard...
The iBooks are small, light, and extremely well built. I've heard a number of people say that they think the fit and finish of the iBook is better than the TiBook.. Add to that the lack of software written to take advantage of the Altivec unit on the G4, and the iBook makes a great choice.
How many seconds does it take to download a few kB rc5 blocks from a big university pipe? (lets be generous and say 5sec or $2.95)... Now how long does it take between downloads? I haven't run an rc5 client in a few years but I seem to recall something like 1Mkeys/sec for a keyspace containing 2^32 keys that's a little over an hour (70 minutes/block).. So I can complete ~20 blocks/day or ~$60.. To rack up $500k would require something like 170,000 blocks or 8500 days.. The questions are: how long did he work there? and how many machines was he running on? With that info and a better estimate of the cpu type/speed and average data transfer rate you should be able to tell if the numbers make sense...
The answer to this, of course, was open-source Linux. Now who is MS's biggest competitor? If you read *any* tech news, you know that it sure as hell isn't Apple or IBM.
Are you sure about this? There are a lot of folks out there talking about Mac OS X, and how it's combination of an opensource (FreeBSD derived) belly and dPDF based interface are very impressive... Now let's imagine for a moment that the iMac2 (running IBM chips) arrives in three weeks and Apple throws a couple engineers at the OpenOffice project, a few more at DV apps (FC Pro, DVD Studio, DVD Player, etc. ), a few at audio apps, and what do you get... You get a pretty formidible challenger to MS..
You don't honestly think that Linux is the answer to MS in the business world at this point do you?..
Wait to see what happens at MacWorld.. There are a lot of rumors floting around, but I wouldn't be surprised to see a silent iMac with a G4 and an integrated flat panel display..
It's easy.. Embed something like a piezo actuator into the structure. As the piezo element is strained it will generate a voltage.. Now make the structure a couple hundred yards long and let it orbit the earth.. Each time it orbits the earth it undergoes a thermal cycle associated with passing through the earths shadow. If the structure is designed like a big bimetallic strip the thermal cycle will induce and oscillation.. Pow! Electricity via structural vibrations..
The shedding frequency of the flow from the bridge approached the natural frequency of the bridge. As this occurred the bridge began to oscillate. Once the bridge begins to move the frequencies will lock, and increasing the or decreasing the flow velocity passing over the bridge will alter the magnitude of the forcing, but the forcing will always be positive. About two years ago I helped an undergraduate ME student set-up an experiment to look at the potential for extracting energy from a low-speed flow using a simple sring mounted cylinder.. He saw that once the cylinder began to move he could up the flow velocity and watch the amplitude of the oscillations increase to a maximum.. Similarly, he could reduce the velocity to a point below where it would begin oscillating..
Apparently I must be one crack.. I think $899 for a 500 MHz PPC G3 with 128MB RAM, a DVD drive, built-in 100Mbit ethernet, modem, firewire, usb, speakers, monitor, and no noisy fans is a pretty descent deal for the average home user. If you want to throw linux on it, go right ahead. I'll choose OS X. It ships with the machine, supports the hardware, and will run legacy Mac OS and Windows (via virtual pc) apps..
I took a look at 0.9.1 yesterday for OS X (fizzila) and it couldn't handle the authenticated SMTP, so I can't use it as a replacement for mail.app on OS X. With mail.app I can send and recieve email through mac.com which is very slick..
The idea that mozilla is shrinking isn't too surprising. As each developer attempts to fix bugs, or improve performance, the code should get tighter. However, claiming that the app is shrinking based on those numbers is pretty silly. A 500kB gain, and 1.3MB dip over 7 entries makes it difficult to say anything more than the app is of order 10MB. Give it a few more iterations, and then take another look.
The PowerPC camp has something of an advantage over Intel in terms of there SIMD extensions.. Namely, the only large company shipping their processors is Apple and Apple is involved in both the compilers and OS for the machines they ship.. Now how does this help? Well, let's look at OS X.. If I develop a code that dynamically links to Apple's libraries and those libraries are written to take advantage of the AltiVec unit, then my app should see an immediate speed-up.. I don't need to do anything crazy, I just need Apple to construct their installer to check the processor type and install libraries optimized for the 2-3 processors they support..
It may also be worth mentioning, that this could probably be done with glibc, but it will be more difficult to support optimized libraries for the umpteen million processors out there..
I haven't read the liscense but if the 'shared source' is only available for reference purposes, and developers are not allowed to USE the 'shared source' in their opensource projects then this could cause problems.. One of the advantages to never seeing your competition's hand is that you can argue quite easily that your code provides a similar functionality without using the same code. By allowing developers to study their routines, Microsoft is poisoning the pool of coders that could construct a 'clean-room' version of their products..
The MS apps for OS X are all Carbon based apps. Therefore, the developers could use a handful of apps such as MetroWorks CodeWarrior, MrC/C++ (from Apple), or ProjectBuilder (Apple/gcc).. I'm sure these are all the same tools that the MS has been using for years...
