I think most of what is good/unique about clojure doesn't come from being lisp though. For example - its concurrency constructs, seq/lazy-seq abstraction, persistent data structures that work with seq, java interop, etc. Being a lisp doesn'

I think I might like this actually. Chrome was a good start to reducing the wasted vertical space in the browser compared to earlier versions of firefox. Combining the address bar and tabs into one line is the next logical option, it might

The paper does mention this: As an example, radon concentrations are known to ﬂuctuate seasonally, as has been noted in Ref. [10], and it was suggested that the decay of 222 Rn could lead to a seasonally dependent charge distribution on the

After having worked at the company I'm at for several years, I've seen quite a few mediocre programmers flounder at the same level for quite a while, none of them particularly improving. I think the same things that keep someone from improv

Most phones do issue a warning if ciphering isn't enabled. On some you may be able to force it to require it. But keep in mind that this is only applied on the radio interface anyways (and GSM encryption is so broken you shouldn't be relyin

I know there are several conversion functions for a USIM to be able to authenticate on a 2G network, but I didn't think it was possible for a 2G SIM to register on a 3G network. Can you explain this more thoroughly?

One of the best things about vim for me is (for example) the command cib. This deletes everything from your cursor forward to the first "(", and everything after to the first ")", then places you in insert mode. How do you do that in your e

Ug... I'm fairly disappointed... His conclusions: - Separating a cold thread from its underlying hot thread is not without performance overhead... Of course cache misses dominate performance. This is basically the first vector that work ste

I haven't read his thesis, but more and more languages/environments are moving to two-level scheduling being the dominant way to get performance. When I read through it later I'll be interested to see how his results are applicable to the s

There is a self tuning linear algebra library called ATLAS. When building, probes various things about your computer, things like L1/L2 cache, if you have fused multiply/add, etc. It uses these to output very highly tuned matrix kernels in

"2. Loop-invariant strlen() GCC does this optimization, because strlen is a "built-in function:" one that gcc recognizes and optimizes specially. Disabling built-ins with -fno-builtin defeats this optimization." No, it does it because strle

Exceptions aren't the only solution though. Conditions/restarts in common lisp seem to be a more powerful but similar alternative. One problem with exceptions is that they can only be one deep. Ie. if you are executing the code invoked by h

I think this is probably true too, that they didn't want to have a separate operator just to reassign a reference. I think it could have been made to work, but just wasn't worth it. Fortran for example has this - pointers in fortran behave

Linked lists are a particuarly poor example though. It is just as easy to make them without null pointers as with null pointers: struct list_node { list_node *next; }; struct list { list_node sentinel; }; IE. A circular linked list.

In rust there is no global mutable state. All mutable state is local to a process. This means that GC happens per task (similar to erlang) instead of per process. This emphasizes safety over performance. You can still drop into C to get bac

Staying calm while thinking through a solution is a pretty useful trait to be hiring for - not just for programmers either. What happens when the shit hits the fan and everything is core dumping left and right - do you really want someone w

I read ithat paragraph as he hoped to build a Polywell, if he could get the money (unlikely). Which would mean that what he built is just a regular fusor.

When you send packets of data out of your phone, there are several layers that are added onto your IP packet. Here is a basic diagram of the different nodes in the RAN and CN and which layers they operate on: UE<->NodeB (Uu): <y

The MSC is part of the core network, and it handles circuit switched calls/data, the SGSN is also part of the core network, and it handles packet switched data. When AT&T is telling you not to use your femtocell for data, it isn't just

Yes, but in an article on copy elision, it doesn't really make sense to talk about small objects because it really doesn't matter if they are copied or not. Pass them by value anyways. What are you referring to about the sorted function - t

Yep, what the author fails to account for is that even locally run projects have a chance of complete failure, and huge budget overruns. It isn't that outsourcing created the problem, poor project management likely created the problem - and

I can understand that interacting with the REPL inside an emacs session might be better than what you can get in vim (haven't tried either yet - I just use a separate REPL session). But is there anything particular about emacs the editor th

Of the tangible features that they list as motivation: - Build libraries for inclusion in IDEs, command line tools, and other analysis tools - gdb seems to have it http://sourceware.org/gdb/papers/libgdb2/libgdb_toc.html - High perf

So basically they want to a debugger as good as gdb, but BSD licensed. I think if this actually matures into something decent, the competition will be good for both projects.

Some times in clojure I've found it easier to express a sequence recursively, rather than iteratively. Using lazy-seq is not only braindead simple for this - just wrap the whole function in it, it is the only way to keep your stack use from

I find this kind of testing incredibly useless. All he did was take the implementation of update-all and do the same thing again for the test! Basically all he is doing is checking that clojure's map function works. When your unit test says

Interesting, when I solved the problem originally on my own, I got to the exact same solution just with different variable names and braces. I suspect that this is probably the most common way to solve it.
