   Maybe you can have an implementation of shared-memory model that is "predictable" (transactional). But I failed to see how that solves the synchronization problem shared-memory model exposed to at large-scale system. On the other hand, GPGP

   Process migration (moving instance) is not easy. In the simplest level, you still want to have some kind of naming/binding scheme such that the migration will be transparent in application layer (well, DNS, maybe). Besides, with your propos

   He can use __attribute__ to enforce noinline: http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html Though these flags are gcc specific (works in clang as well). I found it to be tremendously useful in some cases.

   I feel these days, we as developers are on a death race for high-performance on every consumer device with all these extensions, new languages. And it does impose a problem to library writers: how can I make my library reliable and fast on

   I created this framework to automate tests in ccv: http://github.com/liuliu/ccv . Now it is a very "weak" framework comparing to others. The highlight is: simple and pure C. Granted, some hacks are needed to complete this job. But I hope t

   Redis is single-thread one-process program. Since the execution only happens when EXEC command received, such scenario cannot exist.

   I am eager to replicate your attribute method but haven't got much time to do so. Very excited to know that you are on Hacker News too. My impression is that "verification" problem is already a leap forward comparing to "identification" pro

    I don't see another obvious advantage of Redis over Tokyo Cabinet other than the nicer complex data structure support. I use Redis for several projects and for me it serves well. Particularly, I know the limit of Redis and can predict how m

    Since you are here, what do you think would be a suitable data-structure for SHA'ed key (the first 64-bit) associative array? I implemented a simple tries structure (no compressing at all) to handle this, but constantly struggled that maybe

    Here is my problem with web browser's default form element: inconsistent in their size. For every browser, the default size of form elements varies a few pixels, and that causes the difference in subsequent layout etc. I guess that is the m

    Why having no schema in your ORM is a good thing? I can understand that having dynamic schema on your DB probably will enable you to quickly change columns, indexes and so forth. And I understand that having an object that you can plug what

    I have no knowledge on circuit design, but you should play carefully with randomness. For most algorithms, 1% imprecision with normal/uniform distribution may not be a big deal. But if the distribution is irregular, you may have some troubl

    That's correct. But I noticed a bigger problem: you passed in [x,y] where x is from w to 0 and y is from h to 0. But in your indexing code of grid_1d, it is pos[0] * w + pos[1] which translates to x * w + y. however, since x is from w to 0

    by liuliu 16y ago

    There is a problem in the code that causes the grid_1d implementation to dynamically increase array size on demand. In the test case, it looped over from w to 0, and then from h to 0, thus, the scanline size is (w + 1). In the grid_1d impl,

    I implemented this yesterday mainly because my object models take a lot of repeated pattern for redis interaction. Since redis is not a relational-based database, it won't take care of any kind of relationship between models. In that perspe

    I don't know. It feels like with this line, the job will be run at 7, 14, 21, 28, 35, 42, 49, 56, thus, between 56 and the next 7, you will have 11 minutes interval. Not that familiar with crontab, I may be wrong here.
