So I've traditionally known "the fourth dimension" to be something like time.
I don't consider time to be the fourth space dimension. In a space dimension, you can move back and forth, and the spatial relationship is not restricted to a relationship of cause and effect. We don't know if it's possible to move back and forth in time yet, but we do know that the time dimension has a cause and effect relationship, therefore it cannot be a space dimension.
Miegakure seemed to invent non-natural transposed states of the environment that I, for the life of me, could not understand. How did I know which blocks would appear and disappear leaving only shadows? How do I know how far to go in a fourth dimensional direction? Must the player explore the available transposed states before planning their movements along all four dimensions? So that they can construct an interleaved solution?
I'd say the puzzle is way easier in the fourth dimension because you have one more degree of freedom. Two objects that appear to juxtapose or collide in the lower three dimensions is still collision-free if you consider the fourth. Similarly, although our vision is only the projection of three dimensions to a two dimensional plane, we still understand that an object that appears to be in front of or behind another object doesn't necessary mean the two occupy the same space. If you look at it this way, you can actually play Miegakure with 2D graphics, which would probably be easier.
What might be puzzling in the Miegakure game is the direction of gravity in the fourth dimension. The preferably easiest configuration is to let the gravity to have no effect.
There should be a MacGyver episode where he uses the self-destructing USB swiss army knife as a detonator of some explosives he concocted in order to escape some thug...
I thought the text-only ads from Google will not allow an advertiser to embed Javascript. Not sure about their newer Flash ads which can embed ActionScript, but one would think Google will be more careful with that. Maybe it is possible that Google still unknowingly redirects you to a malware page after you click on an ad, but the pie chart in TFA does not show Google DoubleClick (probably an insignificant amount under Others). In addition, Google may use the automated method behind stopbadware.org to determine whether an ad is clean or not. I'd be surprised if they're not already doing that.
What is interesting is, although the chart does not show Google, the article still lumps Google Ads to their headline. Why? It's more catchy to sling mud on Google? What kind of irresponsible journalism is that?
Drop the anti-social networks, and you will have less unsigned int friends
I thought these social networks give you complex and irrational friends. I don't very much care about transcendental relationships. I'd rather like my friends be all natural, thank you very much.
I've seen insanely illegible handwritings from a student's exam, but they did not claim dysgraphia for which they would be granted the ability to use a laptop, so I graded the handwritten exam. It makes me wonder, how messy does your handwriting have to become in order to qualify as dysgraphia? Furthermore, does messy handwriting alone qualify for it? I saw a sample of dysgraphia on Wikipedia, and I'd say the dysgraphic one is still comparatively legible. My own handwriting could be worse. But the sample is also a semi-memoir of her experience, documenting the mental distress for writing by hand. Does dysgraphia qualification also require the presence of mental distress?
And do you think dysgraphia can be overcome by practice? What would it take to make calligraphy fun?
Not to mention, currently all they do is to extract the timing of notes and the velocity of an existing performance from an old recording, and then play it using a player piano. Their technology doesn't play new pieces. From TFA:
As things stand now, Zenph’s technology looks at actual old recordings to find out how a performer played a certain song, and is not capable of figuring out how a musician would play a new part.
All they do is digital signal processing, not artificial intelligence.
Floppy disks had 40 tracks, numbered 0 through 39. But most floppy disks do have enough surface for one or two extra tracks, numbered track 40 and on. If you format it, you could store extra data on it outside of the file system. This is how some DOS games did copy protection because diskcopy ignored the extra tracks and assumed they did not exist.
The very first logical sector of a hard drive should hold the master boot record and partition table. If your hard drive was never partitioned by you, it would hold a default partition table that shouldn't be hard to guess. If you destroyed the partition table, your OS would not recognize the file systems on it, but you should see the device in the disk management utility which would offer you to partition and reformat the drive. If you guessed the partition table right and write it back, you'll get all your filesystems back.
However, logical sector is different from physical sector. Logical sectors are the numbering accessible by software. Physical sector is only meaningful on the platter. Hard drives have been known to hold reserves of physical sectors so it can map out bad sectors to good ones. The drive could theoretically elect to store such mapping in a physical sector, where the first physical sector holds a root mapping.
I just want to make sure, the data recovery company is talking about firmware in the first logical sector, or the first physical sector?
What leaves me speechless is that the SciPhone must represent more work and more value – and more capability – than its £25 asking price, just in terms of cost of development and production. Just about the only way to be stupider than incurring Apple’s wrath with a forgery, is to grossly undervalue the technology you use as part of that forgery. It’s a bit like making a forged pound coin by melting down gold sovereigns
It actually seems to be a very useful device, sold dirt cheap only because the manufacturer couldn't get over the guilt that they're selling counterfeiting iPhone. Now, I only wish they would design and market a legitimate brand to compete with Apple.
Recursion and inductive reasoning is typically not self-learned, but once you learn it, it's much easier to reason about your program's correctness when you write recursive functions than when you use for-loop or while-loop. Recursion is also key to understand divide and conquer algorithms. Not many people understand that modern computers are designed to run divide and conquer algorithms well. That's because the memory hierarchy exploits locality of reference, which is a property observed from running divide and conquer algorithms. That's because programmers tend to divide a problem into smaller subproblems, and focus on one subproblem at a time.
Furthermore, I would add data structure to this list as well. Many people advocate learning about running time using the big-O notation (you can analyze space usage such as stack depth using big-O as well), but data structure is a big motivation behind the big-O notation.
I also only had to do it once---you can put that into a shell script afterwards with a single letter name if you like---also in my spare time. The total time I spent is less than yours. You still haven't proven your case whether you achieved significant reuse of your code.
I'm not just saying this to win this argument, but I'm making the point that only needing to do things once doesn't necessarily afford you to do it the hard way. Employers who agree with me will hire C#, Java, Python, Ruby, Perl, shell script programmers. Try to find one who agrees with you.
If you were to process terabytes of EBCDIC conversion, it's now a different matter. I guarantee you will be able to write converter in assembly language or C that runs faster than iconv. It's only when you have to do large scale EBCDIC conversion will you be able to justify the time spent writing a highly optimized and specialized solution.
Out of laziness? If you count the number of keystrokes you type to assemble hex2asc.com, asc2bin.com and ebcdicde.com, I think it's pretty clear I have far fewer keystrokes to type. I don't even think you can obtain comparable number of keystrokes if you just enter the machine code with dw. Maybe you can assemble machine instructions in your head, but I can do it quick and not so dirty. You're obviously a smart chap, but when you reach a certain age, all you care about is to get things done in the least amount of time, so you can move on to work on much more interesting problems than character set conversion.
You make your fast-cgi process run for 100 requests and then exit. This way, you reap 99% of the performance benefit of fast-cgi, sacrificing only 1% of performance penalty in order to counter memory leak.
We're talking about C++ as a CGI script. Who cares about memory leaks that only last for the duration of an HTTP request, which is a fraction of a second? The real problem with memory leaks is when you have a long-running process like single-process web browsers.
Davis said privacy law prevents her from identifying the TSA employee. The law prevents her from disclosing what sort of discipline he might have received..... She said privacy laws prevented her from saying if he was fired or left on his own.
It seems that privacy law nowadays are used to protect just the agents of the government, not the people. Ironically, privacy laws are protecting the same agents whose job duty is to violate the people's privacy. I find this even more outrageous than what the TSA employee did to that poor girl.
I currently have a phone number connected to a SIP address, but it only works from POTS lines because my SIP provider operates a SIP to POTS bridge. With this proposal, anyone can operate one trivially. You will just need to get an e164 number assigned to you and configure the DNS entries to point to your Asterisk (or whatever) server.
VoIP providers are in the business of running the bridge, which duplicates the functionality of telephone number to IP address mapping like ENUM. You configure the bridge to route calls to your SIP server, and it all works as intended. What makes you think a POTS provider would be willing to route calls over e164.arpa lookup? If they were to implement something new, might as well ask them to implement dialing by URI.
I also don't see why you want a telephone number to redirect to some URI that the phone might not be able to interact with (say, a landline phone dialing a number that maps to an e-mail address). If the phone understands the URI, just enter the URI directly to the phone. I don't even remember phone numbers anymore, but have much better luck with e-mail addresses and IM screen names.
The ENUM proposal is essentially asking for DNS lookup as a public service run by government or other regulatory bodies. First of all, as you said, why don't we just use names? And second, I'm not sure we want public DNS run by government or regulatory bodies. We already have community-run free DNS service such as http://freedns.afraid.org/ or commercial free service like http://www.dyndns.com/ or http://www.zoneedit.com/. If you're worried that free services would go away, a lot of domain name registries are also offering DNS service at nominal fee, and they would be less likely to vanish. Several people can share the cost of a domain.
All people need to do is to find creative uses of domain names. I think this is the hard part.
Now imagine if every person in an IT-related job went on strike for two weeks. The world would end.
I think the irony is that, if you were a good IT person, and you go on a strike. The system you maintained would be in such a good shape to keep running for another year. Then when something goes wrong, the world ends. But the problem is, nobody can afford to be on strike for a year.

Paste your hex code above to standard input. Out comes ascii in standard output.
I'm afraid all the job postings are looking for C# programmers, not people who can write assembly code. :(
Brits might prefer to say "nitwit" instead of "dumbass."
