I have been given many, many mod points lately, and I spared them on mostly indifferent discussions. I wish I had mod points now; since there is no "FUD", an "overrated" would do fine.
254 (2^8 - network - broadcast) usable addresses per class C network. Where this 251 comes from?
I've got the 192.168.1.42 address, and I have started two connections to 10.1.1.1, specified by the following two tuples:
(192.168.1.42,17890,10.1.1.1,80) and
(192.168.1.42,17890,10.1.1.1,22).
One of them is a connection to a FTP server, the other is a connection to a SSH server. Both are valid, both are NATted fine, both work, even if the local port is the same. Learn what is the key to the NAT state table. Hint: it's not just an "external port number".
I won't dispute the parent's math; I'm too flabbergasted to even continue. I'm sure further on others, too, dispute the parent's post.
Devote some disk space from each machine by creating empty files of the desired size (in W98 workstations, create many 1 GiB files). Write a simple Python (or whatever) that allows the devoted space to be treated as a remote device (elementary control requests and read, write operations in block sizes, whatever that block size may be). Consolidate on a Linux machine, write a little more code using LUFS to connect to these remote devices and build soft raid devices (md-raid, evms, whatever). Make sure that you distribute your subvolumes as evenly as possible among the available remote devices. Create a filesystem on the mega-device. Share (NFS, SMB).
WoW... it appears you Penguins are just 'reinventing the Microsoft Wheel' (same w/ ZFS fans really) - Microsoft's already been there, & DONE that, & it works. [DFS, that is]
A great post. Now, help me to understand its relevancy in relation to TFA:
In a network, there are 100 desktop computers, each with 30 GiB spare disk space. Using DFS, how can I:
create a device / network share / thingie with 3 TiB free space
store a 1 TiB single file on it.
Thanks in advance, Anonymous Coward. Your posts has been most useful so far. Be a good chap and keep up the good work.
Quoting from the ALA post you linked to:
Now sure, you could just shrug it off and say that since IE6's inaccuracies were well-documented, these developers should have known better, but you would be ignoring the fact that many developers never explicitly opted into "standards mode," or even knew that such a mode existed. This sentence is the basic argument I can find in the complete post that can be considered as justifying your "DOCTYPE was flawed from the beginning", or Gustafson's "The DOCTYPE switch is flawed" (the sentence is a round-up of the previous numbered list where "2. IE6's rendering behavior was not updated for five years, leading many developers to assume its rendering was both accurate and unlikely to change." existed).
I can be accused of quoting out of context, but anyone can read Gustafson's post. I fail to accept the logic: "A switch (DOCTYPE) came into existence; its use suggests that the page developer knows what they're doing. Yet, many developers didn't know what they were doing as they used it, and for that, a specific tool is to blame, a very common tool that failed to understand the switch. Ergo, the switch mechanism is flawed."
I'm sure someone can help me understand this logic. Please do.
Actually, there is a very simple and most scientific way to know whether the interviewee is a good programmer (also applicable to whether your girlfriend just had an orgasm): ask them to answer under oath.
I would love to see a multi-core ARM 11 with lots of cache and a GPU-like appendage for heavy number-crunching. It would be low power, fast and could easily run most programs I use daily.
I totally agree. The EeePC and the XO could both have an ARM processor. If only no-one (esp. ASUS) cared for compatibility with the Wintel world...
Windows 1.0 also had a taskbar with active (minimized) apps.
You are talking about the desktop. The desktop contained all active and minimized (observe that parentheses around "minimized" are missing in my text:) applications. These icons were covered when any application ran.
The same fate that will happen to GDDR 6, 7 and 8.
The formula for GDDR versioning is 2^n+1, to avoid confusion with PCIe rates (2^n).
(Did I make it sound plausible enough? I'm interested in quitting programming and becoming the first marketing-decisions-to-laymen communications engineer.)
Now, I am a python programmer and it's a great language, but this type of application would best be handled by a lower level language (I think). Python is great when you need to bang stuff out quickly, or expect to be continuously making code adjustments, but at a (small) sacrifice in performance (which is negligible in a network-limited application). In other words, the exact opposite of priorities than for a mail server (stable well thought out code (note to self: python does not support buffer overflows, too), running as fast as possible (which would be a problem if the python mail server ran on a 4 year old or older machine)).
There. Now it's correct.
If I may summarise: a mail server is not computation-intensive. Give me €100,000 (€100*10^3) for a year, and I will prove my point that python is fast enough (eg compared to postfix) on current hardware for a mail server; of course, we would sign a contract with specific details mutually agreed upon, and if by the end of the year the program wouldn't cover the contract terms, I would give you back your money.
OTOT (on the other tentacle), think of the uses in sex. Satisfaction guaranteed for a female partner no matter what your penile size (or even its existence).
Like I said, I was of the same opinion like you and that was the one case that I was contradicted. I forwarded to that sysadm (hopefully his email address is still valid, haven't had contact with him for some time) the link for the article, he might reply himself or back to me; if the latter, I'll copy the text here.
You do well calling bullshit on "anyone reading slashdot already has 4GB or more", however you shouldn't be so absolute in your next statement:
desktop versions of 32 bit windows do not support more than 4GB of physical address space meaning ram usable to the OS is limited to some figure below that (exactly how much depends on the exact hardware configuration).
Since I hope that you neither omit Windows 2000 and Windows XP from the "desktop versions of 32 bit windows" set, nor are you ignorant about PAE, I have to assume that you talk about incompatibilities with drivers that make Windows report a little more than 3 GiB or RAM available even if there are more; I was of the same opinion as you are, yet a sysadm at a client site shut me up by showing me a system with 6 GiB of memory running WinXP. It was a Dell blade server, can't remember which model though. System properties showed 6 GiB of memory installed. And yes, it felt and was sluggish-- but it had more than 4 GiB of usable memory.
Because, "ubiquitous" as Flash may be, it's not part of "standard" web browsing.
JS is managed by Firefox code, therefore there is a built-in setting whether to enable it or not.
Flash is managed by an extension; it's the Flash extension's (or another extension's, as in the case of Flashblock) job to offer a toggle setting.
I thought it was obvious, but, well, obviously it wasn't. Just imagine a freshly installed Firefox without any Flash plugins installed; the power-user wannabe looks at the settings, checks the "Enable Flash" checkbox, and then writes a post in their blog complaining about the useless setting in Firefox ("I enabled Flash in the Settings, but still could not see any Flash content!!1")
And if you work at Canonical, you don't have to download anything, you take the CD/DVD with you leaving the office.
In the middle of a discussion about finding a non-overloaded server, I suggested to use torrents. Others, too, did as I did. For many people it wasn't obvious that they could download Gutsy through torrent.
May I assume that your own useful suggestion is "get on I2" instead? If yes, do you have info on cost/time needed? If I apply for I2 now, will I get on I2 and download the ISO image in less time than starting a torrent now?
My bad. The info I provided was given to me by a technician in a TV station, and it's quite possible he was talking about the media only (which he showed me) and I misunderstood him.
You do know that Betamax is alive and well, and still used for quality archival purposes in many TV stations around the world, in cases that digital backups are not considered worth it, don't you?

For many, many people, version 2 is much more readable (mind you, this is very simple LISP code). And since you're going to indent correctly your code (either by hand or with the help of an editor), why not make indentation matter? Now you come back explaining why LISP code is perfectly readable by you (irrelevant to my reply) and refuting the value of readability in anyone's code (irrelevant to reality).
The action your metaphor describes is stealing, but the metaphor itself is not correct.
You don't have to pay the ice-cream, as long as you withstand a guy that is shouting and flashing lights at you while you're at the ice-cream stand, and another guy that hands over leaflets to you. These guys are the ones that pay your ice-cream. Also, they might notice (or not, unless they compare their clientèle with the ice-cream seller's one) whether you wear sunglasses, earplugs and refuse to accept the leaflets.
Now, this is closer to the issue at hand.
Banning Firefox is not a solution, since there were (and are and will be) options to avoid advertisements; think proxies (corporate or personal, like WebWasher). I use Firefox, and used to use AdBlock, but I quit; I decided to manage my hostperm.1 file by being very strict, allowing things on a need basis. I now see the occasional advertisement. I don't mind. However, I won't stop using FlashBlock (it gives me a choice), and won't let any site run its scripts unless I trust it.
The thing is, I find it fair to give a little (mind the world, "little") percentage of my bandwidth for advertisement purposes, even if most of the ads are aesthetically unpleasant. However, I want to spread the message to advertisers: "Keep your voice down, stop using those flashes, don't force dozens of leaflets in my throat." BTW, I like Google ads. They have been useful to me once or twice.
