If you have to run handreds of calculations on an array with millions of records then neither Java or Python are good - you better do it in some database system, b/c you need just memory management (which is good today in both Python and Java, Python's results are just more compact) - in that case you'll need data management and thus you need DBMS.
But if your calculations (even simple, like Hello+World) are from separate OS processes, then Java is out of picture. As many people noticed, startup time of JVM is long and class loading is very slow. Python is still ok. Although my tests show TCL has the best performance for such class of tests. Among scripting languages - there are resons to write fork-based listeners on C.
There was also a desire to get out of European politics and detach from England
In other words, it didn't made them different from today's separatists: Kurds in Turkey and Iraq, Basks in Spain, Chechens in Russia. No need to remind Yugoslavia. The difference is that back then separatists were probably about 1% of population of the country (the part to be separated) or even less (99% were Indians).
The extermination came later as the United States moved towards its darker days.
Is the extermination over in United States? How about concentrational campuses for American Japanees in the time of WWII? And how about H1B - the "famous" slavery of 21st century?
Considering that compiling Java into a native executable would seriously improve its performance (and remove the JVM requirement), I wonder why the memo doesn't discuss that possibility?
Java has been designed originally as "compile once, run everywhere".
Well, we all know that it is not true and there is a bunch of code out there that works only on Windows, without serious bugs at least. Also, {J|W|E}AR packages still require some OS-specific packages allowing them to be deployed (for example, RPM on RedHat). So, a developer still has to take care about OS the application will work.
I agree, "cross-platform" idea of java has failed by many sides. Sun begin to realize that scripting langugaes also have many adventages (memory consumption, development time) against comiled one.
Personally, I was always wondering, why not let Java code to be scripted (like Python or Perl), byte-compiled (like it is today) and native compiled (like C++, not like JNI). But that isa my personal point. Deep inside Sun they have to count their political and marketing strategic mistakes. They cannot "fix" them as it won't be a "fix" - that won't be Java anymore. All they need is to either re-write the idea of Java completely (too expensive, especially keeping the backward compatibility) or to give Java up in favor of Python (politically difficult).
Yes, that's right. MS Windows is the highest priority for them. They do it for money, not for fun. And money comes in Java sales from Windoes, not from Solaris.
However, most of problems mentioned in the article are the same on all other platforms. For example the size of "Hello world" program (including RE) and how it grows with complexivity is a real Java problems. Check you memory for even small real-world (10 users, shopping cart with a catalog in SQL) application with EJB (JBoss), no EJB (just Tomcat servlets) and Zope. 250MB vs 75MB vs 15MB.
Java has been developed at time when CEOs/CTOs/COOs/CFOs have been counting fundings, not expenses and profits. When the buzzword had more priority than real features and problems in any technology choices. The time of "golder rush" is over, cool down. Now it's time to think. Sun begins to think. I hope it's not too late.
If the govenment gives Amnesty, then that only encourages more people to overstay or cross the border illegally.
Such thinking is the best illustration of the program of protection against a "cockroach infestation", something that has alwasy been the highest priority for immigration services in U.S.
I don't know about you, but I've left USA because I don't want to wear the "cockrach" stamp all my life and listen "our fathers have been dying to free this country". Well, "to free" from whom? From American Indians, which many nationalities have been just extincted thanks to "freedom fighter"?
I know, many americans have still good brains and sould, clear from TV propaganda. But many are already lost cases. They are just eating-sleeping-working voters and all those immigration changes are to take their votes, not to make any security.
Besides, what makes them think that new tech will help to trace a suicide terrorrists? I don't think that any suicide terrorrist has any plans to come to USA more than once - at least not at this life:)
The getting older by itself does not imprve quality of doing work. Let's call things traight.
Testing - that what's used to filter out components for space programs.
Compare, fo example, Compaq uses very thorough testing of memory stick, which are no fifferent then you buy everywhere. At the end of testing it is certain that sticks work, they have exactly the same latency and other parameters and generally they work exactly as they supposed to. No "plus-minus". That testing is a part of very high price of Compaq computers.
So, time, bby itself, does not make things better. However, time is essential for testing. But what time? No one test anything in real-time mode. Instead, you have specially designed intensive testing procedures involving extreme temperatures ad various radiation levels.
Another thing to know is that any testing is not enough to kill the last chance of failure. What you do is redundancy. You don't have one computer making some function, instead you have three of them doing exactly the same. Then you have the voting system (also redundant) comparing the output of each and making the decision to which of them to trust.
It was a short explanation. In reality you have to build more complicated schema. I don't know what is used by NASA. Perhaps they do what they can on such modest budget.
Or perhaps they should use more experience of russian former space engineers working in America for projects where "citizenship" is not required:)
Right. Two months of C++ debugging in VC and finally your robot will run at scheduled time and press all those COM buttons in various GUI programs. And all was needed is few scripts piped in a single command line.
First paragraph: Japan plans to spend about 1 billion yen (US$8.3 million) funding Asian software developers working on the open-source Linux operating system for consumer electronics goods
...
Last paragraph: In December, Sony Corp (news - web sites). and Matsushita Electric Industrial Co., both major Japanese electronics makers, said they will jointly develop a Linux-based system for digital consumer electronics.
And no even single mentioning of BSD.
My friend from Japan told me once, if they take OSS they prefer Linux and PostgreSQL, not BSD and not MySQL. Japan engineers do not work with dead software.
Somehow I am sure that I was modded down by Solaris zealots - only Solaris zealots could mod as a troll the post correcting the parent by saying that Solaris is more intended for Linux users rather than for Windows one. I wonder what will be a meta-moderation of that mod.
So, you are saying that today % of people picking up M$OS is higher than a year ago?
Again, it's not consistent with a big noise from Apple and Linux news sources. I don't like marketing noise, but I don't think that Wallmart and other are ignoring those statistics when offering pre-installed Linux desktops.
Something is telling me that all those %-numbers are somehow "fishy".
Blackdown is "Java Linux" thing - read their home page.
And you may want to improve your web surfing skills. Because, in 10 seconds from the first (home) page I found that they still have Java for Linux/PPC.
Dispite all the marketing fluff and bluff, Sun doesn't like Linux, that's why Sun's JVM works flawlessly (mostly) only on Windows and Solaris.
And that's the reason why many Linux user prefer Blackdown JVM.
By the way, Sun's Linux JVM is not for Linux - it's only for Linux/x86. Blackdown's version of Linux JVM is for most of working Linux platforms: x86, PPC, Sparc, Arm.
I don't see any politics driving people to prefer Linux vs Solaris on their PC servers and desktops around the world.
Sun may declare that they want Windows users, but in fact usually non-Windoes users are smart and/or free enough to choose operating systems. Therefore, Sun wants Linux (as well as BSD) users to switch to Solaris.
There are three evils for Linux: Microsoft, Apple and Sun. Not sure which is worse.
The decision of sending more robots and less humans to do the orbit job will actually help a lot to many small and mid size companies working with robot technologies. At the end, it may give the impulse to computer industry and it should help to economy after all.
I hope that space craft doesn't need all candy-whistles of MacOSX. All it needs that the OS will just work. And I hope they'll use Linux for it. Thus it might be the highest admitting of the fact that Linux is not only Linux/x86 - it works also on other platforms!
No connection to Columbia tradegy. Just thinking would it be better to use PPC on Space Shuttle and ISS instead of out-dated old Pentiums? I knwo that G{3|4} has much better heat/performance ration than Intel P{3|4}. And I know that NASA prefer old models of Intel chips. Now Iwonder, has G3 or G4 been ever considered to fly?
And this case just adds the oil: perhaps whole PB motherboards can fly, not only Motorolla chips.
I know some small kiosk vendor, who used to build their products on old PB motherboards. Unfortunately, they have mostly moved to Intel notebook motherboards because many customers want wintel-compatible 3rd-party applications. If not that - they would still prefer Apple powerbook motherboards to mount on street walls.
The key to the nickel and phosphorous coating's blackness is that its surface is pitted with microscopic craters.
Pitting the surface with microscopic black holes will make it even blacker.
Besides, it will absorb everything (including matter, not only energy!) very well - good for cleaning industry.
two thing to solve before: how to make microscopic black holes (perhaps in a process of cold fusion?) and how to keep them together (perhaps with dark matter?).
Wait a minute, what is the color of dark matter? Is it black or it's grey a bit?
I guess the high competition in my area (GTA) has allowed the customers a little bit more freedom. In fact, my provider will give minor tech support for most routers and hubs.
I canceled Sympatico within "30 days money back guarantee" b/c of two reasons:
bad policy about the single PC connected;
proprietary client (BTW, no Linux version so far) enforcing that bad policy;
I found Rogers Cable much more friendly who even doesn't change DHCP leased IP address often.
But what I would really love would be a broadband ISP with permanent IP for a reasonable (read: affordable) price. Any advise in context of GTA?
You can boot from USB Zipe (or other USB disk) if BISO supports it. I guess Dell's BIOS does. Besides, AFAIK Dell usually delivers IDE (or ATAPI?) Zip, which is bootable.
But what was really missed a couple of year ago was a universal drive compatible with both Zip and floppy. But since all vendors today supports deliver their software/drivers mostly on CD or Web or both, floppy is obsolete and redundant.
With CD-RW on each box Zip is redundant too. By the way, most of vendors do not support Zip for mass delivery of their software/driver. So, Zip is obsolete too.
I remember that Microsoft kept 14% of SCO's stock that time. Then it was a problem of allowing M$ guys to sit on the board meeting and to spy in Unix strategies. perhaps that's why they have sold Xenix to SCO. Anyway, they have been kicked from SCO board meeting and later (not sure when) sold SCO stock.
I don't think there could be any legal agreement to keep MS from Unix business. The only legal thing I can recall about it would be Unix trademark (now own by SCO as well). But I don't think that the trademark will restrict some specific company (MS) of using it (legally!) in a same way as other can.
The only thing I recall about any restriction for MS from using Unix is the public claims of MS itself swearing of not using it. But that belongs to M$ and M$ is the only one who is capable to change it:)

And if it's not enough, then what would be the difference in price to upgrade your plan?
I would just add two states.
If you have to run handreds of calculations on an array with millions of records then neither Java or Python are good - you better do it in some database system, b/c you need just memory management (which is good today in both Python and Java, Python's results are just more compact) - in that case you'll need data management and thus you need DBMS.

BTW, in Russia many planes has such doors. That's the real life.
In other words, it didn't made them different from today's separatists: Kurds in Turkey and Iraq, Basks in Spain, Chechens in Russia. No need to remind Yugoslavia. The difference is that back then separatists were probably about 1% of population of the country (the part to be separated) or even less (99% were Indians).

Whose is that OS/comapny that lost desktops to Microsoft?
Appla claims it's getting more and more desktop users, especially switchers from Microsoft. There are many news about Linux begins to get on desktops.
So, who else I missed? Whose users switched to Microsoft? SGI? Palm? Non-computerized desktop users?

All right. Just keep your motherboard working in a fridge. But warn your wife to avoid placing some chicken on a top.
