" he must try to delete the images associated with David Lynch's 1984 version of Dune from the public's consciousness "
This means no Dune, at least for me. And I actually don't want to forget Lynch's version - it is one of the best movies I ever saw (first time when I was 12 or 13 years old).
IMHO some remakes are not meant to exist. This might be just one of those [ Another one would be a Cronenberg's Existenz remake ].
What will happen ? Probably some high-speed movie with state-of-the-art photography and visual effects, a typical Hollywoodesque movie made for profit. Not a real movie, from my perspective, a movie that I'd go and watch.
Pretty much all of assemblers I know work the same way (despite syntax). You can also add macro functionalities to some, using external preprocessors. So, if anyone can elucidate me, how does this MASM differ from NASM ? And how does its syntax differs from NASM and AT&T ? I use AT&T syntax a lot (gas), embedded in gcc (for microcontrollers). Do I get any real benefit by using other variants? If so, which benefits ? Alvie
Funny enough, if I do search in Bing for that I get a Japanese page as first hit, and second a Wikipedia page depicting.... "666 is the natural number following 665 and preceding 667". This was actually what I was looking for, not any number of the beast... Sorry google, you're a fail.
typesafe ? Is not C++ type safe ? Where did you read about C++, while listening to some podcast ? Get real man. Read the specs, use it.
Memory safe ? What is exactly this concept of "memory safe" ? Having a GC that does not have a clue of what the programmer wants to do ? To have a such dumb programmer that expects that memory allocations can be entirely managed by other layers ?
Get real. You ain't getting anything better than C++ for the time being.
Oh, sorry. I guess I can run VBscript and Java on this 16kb ROM/2kb RAM controller I have here... or then not.
There's not a single line of useful code there - just reverse engineered (decompiled) py code, which by itself does absolutely nothing.
I don't even think they're bothering to log whoever gets this code (if they can do it in the first place). I did download it to check some "technical" issues and to see how they managed to do it - but it doesn't have a single line of code of the engine - just the usual scripting that one game client has. I'd prefer to look at Unreal Tournament VM (the one who executes UnrealScript) than to this piece of crap (crap cause it is not functional, and cause its not documented).
Transformers are highly efficient (>80%), but only work with AC. Power electronics work with DC, but are less efficient than transformers
Don't forget that most AC-DC converters (like 110V->9V) are in fact DC-DC converters. The AC power is rectified immediately and then a switched DC converter is used, which can achieve efficiencies of more than 98%, using very small transformers, coils and capacitors.
I don't see AC transformers for a long time now. Only SMPS.
use OS X, not PCs So, Apple hardware is not a PC (as in Personal Computer) ?
Anyway, OS X now runs on intel platforms also. Still you might have a point there.
About being easier to have web apps as cross-platform apps, that is not necessarily true. You don't have cross-platform, but you have cross-browser. Even Java fails to some extent to be fully cross-platform. It's sometimes better to use some toolkits like wxWindows or similar.
And web apps do not mean you will need permanent internet access - your employer can have some server that allow you to work even without internet access.
If a device is capable of doing DMA it will need comparatively little time from the CPU to be serviced (bigger transfers can happen while the CPU is off doing other things as opposed to have the device generating interrupts all the time that the CPU has to service before any more data is transferred because some temporary buffer is full and needs moving).
True, but, as you don't have multiple port RAM, you won't be able to access RAM (or you will interrupt the DMA process). Hence, you will rely on the I/D cache - so bigger caches (and presumabilly filled) will help you on the DMA process.
I am not sure on x86 whether the arbiter gives priority to CPU or DMA bursts.
There are drawbacks for all the systems. Once we have dual port SDRAM (if we will ever) there *might* be possible to have the CPU reading the memory (maybe paged/bank based) while the DMA writes on another one.
I am a proud owner of a 3.5G card (HSDPA) and I have some notes about its usability.
I live in Portugal, and not even 3G is accessible in every zone. Lately the cell companies have been improving the access points, and at least I can now connect using 3G in almost everywhere (even in the mountains).
Some things good about this tech:
* I have network access everywhere in my country, in those places I have cellular phones (that means 90+% of the country). It ranges from plain GPRS (64kbit),UMTS (384kbit) and HSDPA (1.8Mbit) - which I am using right now. Some providers are now deploying 3.6Mbit, but coverage and signal strength is not very good atm.
* It automatically switches between the three technologies.
The bad things:
* I never got more than 1.2Mbit. * Low signal strenghts are prone to noise and to packet loss. * Some cards have bad firmwares and crash all the time (mine doesn't so far).
I currently pay about 39 per month. Its slightly lower than I used to pay for 4Mbit ADSL. And I can use it everywhere, and at every time.
My country is about the size of Indiana, so full coverage is not so hard to obtain.
Much more essential for the world's daily operation than these cool kids' PCs, and tied directly to the wallets, by the minute, of most people with any money.
The point is these laptops are meant for people with no money at all.
About whether is essential, I can tell you: What is essential is to give children (who often don't even have anything to eat) the opportunity to technologically advance. You would be surprised to see how many children in the 21th century will die eventually without even knowing what a computer is. And I am not saying necessarly that they will die young.
The "world's daily operation" is a quest for survival. Some don't survive.
Quoting The Hunger Site: About 24,000 people die every day from hunger or hunger-related causes. This is down from 35,000 ten years ago, and 41,000 twenty years ago. Three-fourths of the deaths are children under the age of five.
Either you have high bandwidth you you have low latency, TCP speaking.
But pings are ICMP, not TCP, so that does not directly apply.
Ping slowdown (slow rate) in OS/X its probably a rate limit. To prevent DoS attacks.
I bet OS/X fails horribly transferring files over noisy links, or in high congestion situations, but nowadays we don't use those noisy links anymore (we do congestion tho) so that makes some sense.
No one has spoken yet about ECN. That can play a major role too in window scaling.
My point is simple: what you get is what you tune your OS for. I know Linux/BSD can be fine-tuned. I believe M$ Windows can too, but I'm not sure.
Still my first post was only to enlighten what TCP and sliding window protocols were all about. Some more issues arise when dealing with high bandwidth transfers, such as interrupt congestion at CPU bus, DMA, layer-2 aware NIC cards, and so on...
For example, 10Gbit cards are here, but that makes at 64bit a speed of 312Mb between peripheral/memory and memory/cpu. Pretty high. At 32bit/transfer makes 624Mb/sec... half of a FSB running at 1GHz.
I remember "freezing" NT4 just by flooding it over a 100Mbps link with IGRP packets. The mouse froze completely.
Take a truck. A huge one. Fill it up with recorded DVD's and send it over a hundred miles distance.
You'll have huge bandwidth.
But wait, somehow a DVD got lost in transit. What now ?
You have to phone back and have a taxi to pick it up and deliver the missing DVD.
As you need the last DVD, you'll have to wait. Your bandwidth decreases.
It's pretty much costly for you to do so if you miss a DVD.
So you decide to take only a hundred DVD's per truck and using multiple smaller trucks. But somehow none is missing this time, so you spent a lot of money for the extra trucks.
But you know that does not really solve the problem. Window Scale just allows you to "adjust" your window further than the 64Kb. Also a packet loss with a large window has some dramatic consequences, and to address that is not easy.
Second large windows degrade what we call "fair queuing" mechanisms: splitting bandwidth over multiple TCP/SWP connections. Large windows cause a lot of congestion.
(...) It becomes clear that TCP can not utilize the full bandwidth because after having transmitted a window of data, it must wait until the acknowledges come back from the receiver. Because the delay is the same as on the normal speed link, there is a long pause between sending the last segment of the window until a new window is opened by the acknowledments.
(...) You don't need Java to get program portability.
So true.
I remember a few years ago I was called to attempt fixing Y2K bugs on one SVR4 that ran proprietary software - intel-based UNIX (DYNIX). There were concerns that the OS would not handle Y2K well, so we had to find an alternative.I chose Linux for the job. Why? It was free, and it supported iBCS.
Most people never heard of iBCS. I used iBCS to successfully run all native DYNIX binaries under Linux with basically no hassle (had some trouble setting the printing system though).
Also most people are not aware that Linux supports several personalities.
At IBM, we took a two hour class on how to respond to ISO 9001 auditors. I'm not kidding.
I also took some classes for an ISO9001 audit. I know how they are.
And we didn't know what the process was, they never told us, we just were to point them to Timmy. And Timmy didn't know, Timmy was supposed to point them to... ad nauseum. ISO 9001 is nothing.
Well let me ask you:
You ever had an SQA person or the like (Software Quality Assurance) working with you?
Did you (and your managers) review periodically the project plan to ensure it was on-time, on-effort and on-budget?
Because it did not work with you (and your superiors) does not mean it does not work with other companies.
You still have to follow a good Quality Policy. Certification is only a small part of it. The least important, IMHO.

This issue is somehow similiar to Heisenberg's Uncertainty Principle. You cannot get maximum bandwidth and minimum latency.
Linux can respond faster if it has to. OS/X doesn't do that because it does not want to.
It can also respond slower:
$ cat
250
Tune it as you wish.
Yes, I had some beers today, and what?
Surely.

I've all those TCP "flavours" available. Some are good for high-speed links, some for high-latency, some for low-congestion and so on.
There are some other issues around that may arise if you have some other "active" node in between the endpoints (such as routers). But you know that.
