I am planning to quit my job and study algorithms full-time for one year. Can anyone give me some advice?

It is worthy of praise.

Answer by Sunling Yang:

Hey I actually quit my job 2 months ago, studied full-time and am now working at Google so it can be done!

My situation so you can gauge how much it applies to you: I was working at a startup as a software engineer with really long hours and quit for the same reason: wanted to leave and needed time to interview. I had a CS master's and before that I was in Physics, so I spent a month drilling CS fundamentals as I wasn't one of those people that started programming at 8 years old (more like 21). It was time well spent in my case as I really like all things CS (hence the career switch) so I had a lot of fun by myself studying, but I don't recommend being jobless for more than 2-3 months, as the loneliness and the lack of a constant routine can become chaotic (I was lucky to have a bunch of awesome friends that spent time with me on their days off and I tried really hard to always keep a routine of studying 10-5 and after a month I was interviewing regularly), not to mention after 2-3 months the lack of employment starts to look bad on your resume to employers.

All the factors that made it work:

1. I knew that I was okay in Algorithms being from a Physics background and I was weak in Object-Oriented Design, actual coding in general, and systems. So I worked through every problem in Cracking the Code Interview and some of the problems in Coding Interview Questions (some of the solutions might not be correct but they made good coding exercises). I would implement the code in Python and Java and run them in term and Eclipse to make sure the code actually runs correctly. This is crucial for Google and Amazon as they look for right-off-the-bat working code. Another really good book with good questions is Algorithm Design Manual by Steven Skiena. Also Programming Pearls by Jon Bentley really put everything in focus for me: why interviewers are so obsessed with anagrams and palindromes, what each different sort is good for, etc. I also crawled through the Design Patterns (Gang of Four) book and got to the bottom of dependency injection. Not sure whether that helped with solving the problems but it definitely made me a better programmer.

2. I had a practice partner for white-board sessions. One of my past coworkers was also looking for a new job so we took turns practicing white-board sessions for a month. This was crucial for me as I used to freeze before the white board and write all over the place. My coworker also recommended several key systems papers to me: Bittorrent (p2p), Google BigTable, Google GFS, Google Spanner, and Amazon Dynamo, and they were useful for system design questions (Google didn't ask me any, as they considered me to be junior-level, btw, but Amazon did). The swapping tips and the comaraderie really kept me from freaking out about not having a job for the first time since I graduated college.

3. Another reason why I went for this nuclear option of "quit first, find job later" was that I was already recruited by Facebook and Tumblr at the time and I was confident about finding a job even if those fell through. I ended up not advancing up either company, btw, but my applications to Google, Amazon, and LinkedIn went through and I did interview with them, so FB and Tumblr ended up being good practice. So my advice is to interview with a bunch of other companies first so you get some practice explaining to interviewers what you are doing on the board, giving the elevator speech about your resume, etc. There was a downside to spacing out the interviews though: I ended up waiting to hear back from Google and having to postpone responding to Amazon and could not properly bargain for a better salary, but at least I got the job so it's not the worst situation.

All in all, if you do decide to carry out this plan you probably don't need 1 year, and if you can find a support group it is highly recommended. Best of luck!

Which is the best out of these three formats: MP3, AAC, or AIFF?

Answer by Lancy Spears:

There is no the best one, but is the most suitable one for you.
The differences of the three:
MP3 (MPEG-2 Audio Layer III)
Filename Extension: .mp3
Format Type: Lossy Compressed
When Internet file-sharing boomed into popularity with Napster and the iPod, the MP3 cornered the market for one reason: it had a small footprint. Without broadband connections, it was impractical at the time to share file sizes larger than the MP3 standard 2 – 3 Megabytes.
And that preference has stuck for some time now even though MP3 does not have nearly the same amount of quality as WAV or AIFF files. But despite this growing base of people using higher quality formats, there are still those who prefer the MP3 — whether out of nostalgia or quality, who knows.
What does this mean for you?  Well, the MP3 format uses compression which actually removes data from a song using complicated algorithms. The reason for removing this data is to save space and make the file smaller.
So, if you have a slower internet connection or limited hard drive space, MP3 could be your file format of choice. If you’re worried about quality loss, don’t fret too much about it. While, yes, there is a noticeable drop off in sound quality, MP3 files fall square under the “good enough” umbrella.

AIFF (Audio Interchange File Format)
Filename Extension: .aif or .aiff
Format Type: Uncompressed
In terms of file size and quality, AIFF and WAV formats are fairly interchangeable. For you techno-junkies, the AIFF format results in an uncompressed PCM (pulse-code modulation) file meaning it still has relatively large file sizes, but maintains a higher quality of sound.
In fact, if you check out some of the free stock music on this site, the AIFF files and WAV files have similar file sizes as WAV also uses PCM.
Again, AIFF files offer a lot of flexibility in editing, copying, changing file formats, and other post-production activities. They are the Apple/Macintosh equivalent of WAV files, though both Windows PCs and Apple Macs will recognize either format.
Reblog from Which Audio File Format is Right For You?.

Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. Designed to be the successor of theMP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates.[2]
AAC has been standardized by ISO and IEC, as part of the MPEG-2 and MPEG-4 specifications.[3][4] Part of the AAC known as High Efficiency Advanced Audio Coding (HE-AAC) which is part of MPEG-4 Audio is also adopted into digital radio standards like DAB+ andDigital Radio Mondiale, as well as mobile television standards DVB-H and ATSC-M/H.
AAC supports inclusion of 48 full-bandwidth (up to 96 kHz) audio channels in one stream plus 16 low frequency effects (LFE, limited to 120 Hz) channels, up to 16 "coupling" or dialog channels, and up to 16 data streams. The quality for stereo is satisfactory to modest requirements at 96 kbit/s in joint stereo mode; however, hi-fi transparency demands data rates of at least 128 kbit/s (VBR). The MPEG-2 audio tests showed that AAC meets the requirements referred to as "transparent" for the ITU at 128 kbit/s for stereo, and 320 kbit/s for 5.1 audio.
AAC is the default or standard audio format for YouTube, iPhone, iPod, iPad, Nintendo DSi, Nintendo 3DS, iTunes, DivX Plus Web Player and PlayStation 3. It is supported on PlayStation Vita, Wii (with the Photo Channel 1.1 update installed), Sony Walkman MP3series and later, Sony Ericsson; Nokia, Android, BlackBerry, and webOS-based mobile phones, with the use of a converter. AAC is also supported by manufacturers of in-dash car audio systems[when?][vague].

Is a person who has spent a couple of months or years in prison ever able to come back to normal life?

Answer by Terry Lee:

Yes.  I spent 51 of my 71 years locked up in California.  But the same stubborn independence that led me to reject the laws of society also helped isolate me from the toxic effects of more than a half-century of confinement. 
Some guys in the slammer let their brains be completely washed, rinsed and set in jailhouse concrete.  But not me.
Never did the tattoo bit, swaggered around, carried a shank or pumped iron to obtain a Tweety Bird physique (although I did run the second marathon at Folsom State Prison).  I just did my time as problem free as possible by following a few basic rules.  Like never snitch, always pay your debts promptly — or avoid borrowing or lending altogether — never provoke the lunatics (among the keepers and the kept), and always be helpful and courteous but firm.
One big advantage I had was that, as a former engineer, I did a lot of repair work.  Fixed radios, TV sets, Walkmans, earphones, watches, CD players and so forth.  Was usually the most skilled repair tech in whatever prison I was incarcerated.  As such, my position was similar to that of a piano player in a rowdy, 19th century saloon of the Old West.  On the wall above these hard to find musicians was often a sign that said, "Please do not shoot the piano player."
In a similar way, prison shot callers told everybody, "Don't fuck with the fix-it man."
As a result, I had carte blanche in the highly polarized prison environment to move among all races and even mediate small conflicts.  Some guards at certain prisons allowed me to operate a repair shop out of my cell in order to make their jobs easier.  That is, by repairing items they accidentally broke during shakedowns.
As I pointed out in a TV Guide article, cell TV sets had a certain tranquilizing, or "electronic babysitter" effect, and so the guards found that
the more TVs that remained in good working order, the fewer problems they had to deal with among the prisons' captive TV audience.
I finished a final 26-year term on December 31, 2010 and at age 67 — highly embarrassed over life choices — decided not break any laws.  Simple as that.  Had been in all kinds of counseling sessions and group therapy meetings for decades.  I wrote hundreds of pages of therapy assignments which impressed doctors and social workers. 
But for me, all the psychobabble and overthinking and eloquent dissertations didn't matter as much as a stubborn resolve to go straight.
I remember walking into a supermarket shortly after I got out and looking around, feeling rather disoriented but fascinated with the simple acts of people selecting merchandise and paying for it at cash registers.  In the old days, when shoplifting was my most compulsive form of theft, I'd be scheming at length on how to sneak various items out of the store. 
But now, as I watched the everyday people in the supermarket function like a microcosm of society, I thought, Hey, I can do this too!  It's not that hard!  I can be just like everybody else!
