Is there an SQL for files? I mean, something like, SELECT linenum, line FROM file 'whatever.txt' WHERE line LIKE %foo% AND so on SORT BY line ASC LIMIT 10.

This isn't something that I need, I'm just curious whether anything like it might exist.

Well, they're defining it this way:

FastPath Single - Decodes directly into one macro-op in microprocessor hardware.
FastPath Double - Decodes directly into two macro-ops in microprocessor hardware.
Microcode - Decodes into one or more (usually three or more) macro-ops using the on-chip microcode-engine ROM (MROM).

But I don't see how you could code LEAVE in less than 3 ops and I don't see why you'd proscribe against 'microcoded' instructions as a blanket recommendation anyway. It's not a very useful distinction at that granularity.

I haven't had time to look through the thread, so sorry if this has been asked before. What is the best language to learn for the sake of having programming knowledge? Is there one language that is more extensively used, or perhaps one that will help you better understand programming in general? I've taken a course in C and one in C++; should I learn more about them or try something different?

Internet Janitor: May 17, 2008; "That isn't the appropriate trash receptacle."

EF: Do you intend to do anything practical, or are you more interested in programming from a theoretical/puzzle solving perspective?

In my highly opinionated... opinion:
Lisp weenies would probably suggest Scheme is a great language for learning about programming from a high-level, abstract standpoint.
Java and C# are great general-purpose languages with libraries for drat near anything, but you often have to type a lot, and there are tons of awful examples online.
Python, Ruby, Perl and PHP are all more generally of the philosophy that common tasks should have short, cryptic solutions, to varying degrees of insanity.
Forth is fun if you like the idea of coding in assembly but making loops out of branches gets old too quickly.
C and C++ are useful if you see yourself going into the industry, but probably more trouble than they're worth if you just want to have fun.

Yeah at this point I wouldn't learn C/C++ unless there is an intrinsic career reason to do so (e.g. a job) or a specific academic one. I learned both long ago and haven't used them in... ten years? ANSI C especially was helpful from a structure/discipline standpoint, but you can get that from other interpretation-light languages.

If you just want to screw around I'd suggest something in .NET if you don't have a problem with Microsoft. If you want to go deeper Java is a good choice, though with many frustrating/ineffable compromises. If you want a job quickly, sadly, PHP/ruby/etc. might be a good way to go.

I'm far from a professional and don't have the background to make any assertions about this, so I'm curious about what you mean here WRT Python?

When I was first "learning programming" a few years ago, I stopped and started with a few different languages, but finally stuck with it once I tried Python because I found it amazingly un-cryptic.

If you're willing to sink a shitload of time into it, I would really recommend working your way through SICP. It's going to be awhile until you get far enough into it that you'll be able to talk to people about programming "in general," though.

Python owns. Don't believe that guy who said it was cryptic -- at the core of the Python philosophy is making things clear, explicit, and obvious.

IMO, you shouldn't learn just one language. Learn a whole bunch at the same time! Pick two really different languages (for me, this was C++ and Python), and work through Project Euler or something -- when you figure out how to do something in one language, figure out how to do it in the other one. Try to understand what makes the two implementations different, try to think about what kind of design choices the language designers faced, etc. To be a good programmer you have to be able to think of things from several different angles at once, and working with multiple languages and trying to understand the WHY of them is good practice for that.

I don't "get" Agda. I'm doing exercise 2.2 of Dependently Typed Programming in Agda and I'm completely stuck.

quote:

Remember tabulate and _!_ from Section 2.4. Prove that they are indeed each other's inverses.

(a) This direction should be relatively easy.
code:
lem-!-tab : forall {A n} (f : Fin n -> A)(i : Fin n) ->
            tabulate f ! i == f i
lem-!-tab f i = {! !}

(Here are the definitions of tabulate and Fin and _!_)

code:

data Nat : Set where
  zero : Nat
  suc  : Nat -> Nat

data Fin : Nat -> Set where
  fzero : {n : Nat} -> Fin (suc n)
  fsuc  : {n : Nat} -> Fin n -> Fin (suc n)

_!_ : {n : Nat}{A : Set} -> Vec A n -> Fin n -> A
[]        ! ()
(x :: xs) ! fzero    = x
(x :: xs) ! (fsuc i) = xs ! i

tabulate : {n : Nat}{A : Set} -> (Fin n -> A) -> Vec A n
tabulate {zero} f = []
tabulate {suc n} f = f fzero :: tabulate (f o fsuc)

data _==_ {A : Set}(x : A) : A -> Set where
  refl : x == x

To me, it seems like the proper way to do this is to wave my hands and cry "refl!" and hope that the unifier figures it out. I don't get how to actually do this though.

I can't promise you the exact Agda syntax right now as I don't have a compiler handy, but I'll walk you through the proof skeleton I'd use.

You have a function to tabulate, and a bounded index. Pattern match on the index.

If the index is zero, you're asking if tabulate f ! fzero == f fzero. This is a trivial consequence of the definitions of tabulate and !, and the unifier should handle it. For that case, simply provide the proof refl.

If the index is nonzero, you're asking if tabulate f ! (fsuc i) == f (fsuc i). This is nontrivial. If you walk the definitions of ! and tabulate slightly, you are asking if tabulate (f o fsuc) ! i == f (fsuc i). Consider g = f o fsuc. You can recurse using lem-!-tab g i to show that tabulate g ! i == g i. You need to show that g i can replace f (fsuc i), but because that's a trivial proof the unifier can handle it.

So your final proof should look something like this:

code:

lem-!-tab : forall {A n} (f : Fin n -> A)(i : Fin n) -> tabulate f ! i == f i
lem-!-tab f fzero = refl
lem-!-tab f (fsuc i) = lem-!-tab (f o fsuc) i

Yeah if you're EE you're probably going to be stuck with ANSI C for life if you're doing programming/design, just so many embedded systems. For a laugh check out the Coding Horrors thread, where the recent mantra is 'EEs are the world's second worst programmers (after dedicated academics)'.

Python is pretty neat, and relatively low investment to learn.

Oh sure, I didn't mean to imply it wasn't good for anything else.

My own question: I've got a collection of flat surfaces in 3-dimensional space that form the facets of some arbitrary polyhedral solid with nothing "weird" about it (although it's not necessarily convex).

Now, my geometry library can assemble them into a representation of the solid that I can then perform boolean set operations on, which is what I eventually need. The problem is that it can only do this if they're all oriented the same, i.e. applying the right-hand rule to each of their vertex series yields vectors that all point the same way relative to the interior of the solid. (Alternatively, it will only work if there are no duplicate directed edges.) Unfortunately, I'm going to have to enforce this myself, but I can't think of an elegant way to do it. All I can think of is manually examining the set of directed edges and flipping the order of a surface if I encounter any duplicates, but that feels kind of brute-forcey. (Fortunately, I can get away with that - I won't encounter more than about twenty surfaces so performance isn't a huge issue.)

That's how I was trying to prove it. It turned out my problem was that tabulate f ! i == f i should be (tabulate f ! i) == f i.

Visual Basic question, I'm using Visual Basic 2008 express edition. I am trying to figure out how to see when a mouse button is clicked anywhere on the screen but I'm running into a brick wall I guess. I see there are nice functions like SetCursorPos and GetCursorPos that can set/get xy coords easily. I see the mouse_event function that can let me send clicking events. How do I receive buttondown/buttonup events even if my form isn't visible or under the mouse cursor? I've been trying to make sense of the SetWindowsHookEx but then I see documentation that says it doesn't work globally?

Thanks, I was thrown off by things saying global hooks weren't supported in .net
This worked perfectly, I just had to shut off the Close button and put my own exit button in.. the code I found for a low level mouse hook did override the finalize function to insert a command to shut down the hook.. but for some reason when I hit the close button it would freeze my mouse and the program for a few seconds. Doing it myself in my own exit button works perfectly though. Weird as hell.

All well, I can count mouse clicks now which makes me happy.

# ? Oct 9, 2011 05:34

Sedro: Dec 31, 2008

My guess is closing the window kills the message loop, so your callback is no longer accessible by Windows. The finalizer runs eventually and your hook gets released. That is one of the dangers of hooks- if your process stops responding, input stops working.

You should have some event like OnClosed where you can stick your cleanup code. Generally you want to use the finalizer as a last resort, especially for critical cleanup. Check out the disposable pattern.

# ? Oct 9, 2011 06:42

Nullsmack: Dec 7, 2001; Digital apocalypse

It merits further experimentation. I think at one point I followed someone's code to make a "are you sure you want to exit" box show up when you close the form.. but before it did show up, the finalize code ran to unhook the low level mouse hook and caused the program and my mouse to hang for a few seconds. Might just be stuck with having my own exit button unless I can figure out how to have the regular close "X" button setup to work like my exit button. It's not a big deal either way.

Ration: Dec 3, 2005; My mile could not pump the plumb

SQL Question:

I have a google maps API (v3) query dumped to an XML.

I have two tables. I'm calling a query to select all elements of one table and a few of the second.

The second table contains a "rating" field. There are multiple entries and I have the two tables linked by ID.

The two tables correspond, everything is fetching correctly, but it outputs the field "rating" as multiple entries. This causes me to have duplicates with (potentially) different output.

AVG will be the solution! So, I implemented the AVG(rating) AS ratingavg.

It is giving me the average of the entire table, as opposed to the results from the above search. I do not need the entire table to be averaged, just the ratings that apply to the query. How can I accomplish this?

I'm assuming that I'll have to use a case... but I'm clueless as to how to work it out. Google has failed me.

In short: I need the AVG(rating) of the resulting query, not the entire table.

code:


<?php
require("mydbshit.php");

function parseToXML($htmlStr) 
{ 
$xmlStr=str_replace('<','&lt;',$htmlStr);

AVG() is called an aggregate function. Aggregates run over the entire dataset, unless you tell the database system how to the rows in the intermediate result set are related in groups.
(Other aggregate functions are COUNT, MIN and MAX.)

You need to add a GROUP BY clause to your query:

code:

SELECT markers.name,
       markers.id,
       markers.address,
       markers.lat,
       markers.lng,
       markers.sname,
       markers.tele,
       markers.url,
       comments.page_id,
       AVG(comments.rating) avgrating
FROM   markers,
       comments
WHERE  markers.id = comments.page_id
GROUP  BY markers.id

This tells the database system that all results with the same marker-id forms a single group, and aggregates must be performed over those groups.

You may also want to read up on joins, what you probably want to do here is not an inner join (as you are getting now) but more likely a left join, where even markers without comments are included in the result set.

I've been learning Ruby- both for Rails and other frameworks like it, and as a general scripting language. It's my first language period, and I've been enjoying it. But one thing I can't seem to find is any sign that people actually use the language for something -other- than Rails. Is Ruby just overshadowed by its best-known framework, and I'm not seeing the people using it otherwise? Or is it legitimately a one-trick pony, only otherwise useful for quick scripts? :v:

Ruby is known almost exclusively to the general programming-language-aware public as the language Rails is implemented in. But there's plenty more. For example, looking on GitHub (https://github.com/search?type=Repositories&q=language%3Aruby), I see:

homebrew, a package manager for Mac OS X
blueprint, a CSS framework
jekyll, a static site generator
chef, a systems integration thinger

In that search you'll undoubtedly notice that the proportion of Rails-related projects vastly exceeds any other group, but don't let that discourage you on Ruby. And (while it's in early stages) there are Ruby apps in the Mac App Store.

Specifically:

This is the first assignment we had to do for my XML class this semester, and I feel like I really shouldn't be creating a new XPathNav/Doc/NodeIterator in each function, but I'm not sure where the best/proper place to put it is.

edit; Hmm. When I first typed out that application, I typed everything out so that it'd all be executed in the button click handler, and it works fine. When I seperated it out into 3 different functions, the popItems function doesn't work properly. There are 3 items in the XML file, and when the popItems functions runs it only prints out the first of the three. Not really important- I can just ask my professor next class, but this struck me as really strange.
