  • Interpreters: How much simplification?

    - by Ray
    In my interpreter, code like the following x=(y+4)*z echo x parses and "optimizes" down to four single operations performed by the interpreter, pretty much assembly-like: add 4 to y multiply <last operation result> with z set x to <last operation result> echo x In modern interpreters (for example: CPython, Ruby, PHP), how simplified are the "opcodes" for which are in end-effect run by the interpreter? Could I achieve better performance when trying to keep the structures and commands for the interpreter more complex and high-level? That would be surely a lot harder, or?

  • Player & Level class structure in 2D python console game?

    - by Markus Meskanen
    I'm trying to create a 2D console game, where I have a player who can freely move around in a level (~map, but map is a reserved keyword) and interfere with other objects. Levels construct out of multiple Blocks, such as player(s), rocks, etc. Here's the Block class: class Block(object): def __init__(self, x=0, y=0, char=' ', solid=False): self.x = x self.y = y self.char = char self.solid = solid As you see, each block has a position (x, y) and a character to represent the block when it's printed. Each block also has a solid attribute, defining whether it can overlap with other solids or not. (Two solid blocks cannot overlap) I've now created few subclasses from Block (Rock might be useless for now) class Rock(Block): def __init__(self, x=0, y=0): super(Rock, self).__init__(x, y, 'x', True) class Player(Block): def __init__(self, x=0, y=0): super(Player, self).__init__(x, y, 'i', True) def move_left(self, x=1): ... # How do I make sure Player wont overlap with rocks? self.x -= x And here's the Level class: class Level(object): def __init__(self, name='', blocks=None): self.name = name self.blocks = blocks or [] Only way I can think of is to store a Player instance into Level's attributes (self.player=Player(), or so) and then give Level a method: def player_move_left(self): for block in self.blocks: if block.x == self.player.x - 1 and block.solid: return False But this doesn't really make any sense, why have a Player class if it can't even be moved without Level? Imo. player should be moved by a method inside Player. Am I wrong at something here, if not, how could I implement such behavior?

  • Spritegroups and colorkeys

    - by Fristi
    I have a problem using spritegroups in pygame. In my situation I have 2 spritegroups, one for humans, one for "infected". A human is represented by a blue circle: image = pygame.Surface((32,32)) image.fill((255,255,255)) pygame.draw.circle(image,(0,0,255),(16,16),16) image = image.convert() image.set_colorkey((255,255,255)) An infected by a red one (same code, different color). I update my spritegroups as follows: self.humans.clear(self.screen, self.bg) self.humans.update(time_passed) self.humans.draw(self.screen) self.infected.clear(self.screen, self.bg) self.infected.update(time_passed) self.infected.draw(self.screen) Self.bg is defined: self.bg = pygame.Surface((SCREEN_WIDTH, SCREEN_HEIGHT)) self.bg.fill((255,255,255)) self.bg.convert() This all works, except that when a red circle overlaps with a blue one, you can see the white corners of the bounding box around the actual circle. Within a spritegroup it works, using the set_colorkey function. This does not happen with overlapping blue circles or overlapping red circles. I tried adding a colorkey to self.bg but that did not work. Same for adding a colorkey to self.screen.

  • Self hosted Netvibes alternative [on hold]

    - by Jens
    I am looking for a self-hosted alternative to part of the Netvibes functionality. It should act as feed reader, show my mail inbox, a list of bookmarks and maybe the weather forecast. I wish to move away from Netvibes since I don't care to share my browsing habit, and certainly not my mail password, with another person or company. I am certainly willing to invest some time in setup, maybe up to writing a plugin for a solution that does not fulfill all my requirements. Dou you have suggestions on where to look?

  • Cloud hosting vs self hosting price

    - by yes123
    I was looking at some cloud hosting price. Consider an entry level self hosted server: PRICE: 40€ ---------- CPU: i5 (4x 2.66 GHz) RAM: 16GB hard disk: 2TB Bandwidth: 10TB/month with 100Mbps Now consider an equivalent on a cloud structure... (for example phpfog) PRICE: 29$ -------------- RAM: 613MB (LOL WUT?) CPU: 2 Burst ECUs Storage: 10GB (WUT?) Basically with cloud, to have the same hardware of your entry level dedicated server you have to pay 300-400€... Is it normal? I am missing something?

  • Do you think code is self documenting?

    - by Desolate Planet
    This is a question that was put to me many years ago as a gradute in a job interview and it's kind of picked at my brain now and again and I've never really found a good answer that satisfies me. The interviewer in question was looking for a black and white answer, there was no middle ground. I never got the chance to ask about the rationale behind the question, but I'm curious why that question would be put to a developer and what you would learn from a yes or no answer? From my own point of view, I can read Java, Python, Delphi etc, but if my manager comes up to me and asks me how far along in a project I am and I say "The code is 80% complete" (and before you start shooting me down, I've heard this uttered in a couple of offices by developers), how exactly is that self documenting? Apologies if this question seems strange, but I'd rather ask and get some opinions on it to gain a better understanding of why it would be put to someone in an interview.

  • Multitenant Self-Service Provisioning Anwendung

    - by Ulrike Schwinn (DBA Community)
    Oracle Multitenant ist eine neue Datenbank-Architektur, die seit Oracle Database Version 12c zur Verfügung steht. Konsolidierungen, schnelles und vereinfachtes Patchen, Provisionieren und Klonen einer Umgebung sind nur einige Vorteile, die sich aus diesem neuen Konzept ergeben können. Die Idee dahinter ist, dass sich mehrere Datenbanken nicht nur Ressourcen wie Hauptspeicher und Hintergrundprozesse teilen, sondern auch eine gemeinsame Verwaltung ("many as one") möglich ist. Oracle Multitenant ist natürlich auch eine ideale Grundlage für "Database as a Service", weil damit eine neue Datenbank in kürzester Zeit erstellt werden. Daher steht seit September auf OTN der Download einer einfachen, intuitiven Weboberfläche für Multitenant Self-Service Provisioning zur Verfügung. Was steckt dahinter? Wie funktioniert die Installation? Welche Anwendungsmöglichkeiten gibt es? Diese Fragen und weitere Informationen sind Thema des aktuellen Tipps. Mehr Informationen dazu gibt es hier.

  • Releasing an open source project without getting embarrassed

    - by Hopeful
    I've been working by myself on a fairly large open source project for quite a while and it's nearing the point where I'd like to release it. However, I'm self-taught and I don't really know anyone who could adequately review my project. A few years ago, I had released a small bit of code which pretty much got ripped apart (in a critical sense) on the forum where I released it. Even though the code worked, the criticism was accurate but brutal. It prompted me to begin searching for best practices for everything and in the end I feel that it made me a much better developer. I've gone over everything in my project so many times trying to make it perfect that I've lost count. I believe in my project and think it has the potential to help a lot of people and I feel like I've done some cool things in interesting ways with it. Still, because I'm self-taught, I can't help but wonder what gaps exist in my self-education. The way my code was ripped apart last time isn't something I'd like to repeat. I think my two biggest fears with releasing my project that I've poured countless hours into are being absolutely embarrassed because I missed some patently obvious things because of my self-education or, worse, releasing it to the sound of crickets. Is there anyone who has been in a similar situation? I'm not afraid of constructive criticism, so long as it is constructive and not just a rant on how I screwed up. I know there is a code review site on StackExchange, but it's not really set up for large projects and I didn't feel like the community there is large enough yet to get good feedback if I were to post parts of my project piecemeal (I tried with one file). What can I do to give my project at least some measure of success without getting embarrassed or devestated in the process?

  • Self-hosting vs. Budget hosting - What are the economics?

    - by cdonner
    My current hosting provider (shared Linux, unlimited domains, < $10 per month, with about 20 sites) has been giving me a lot of grief lately. I am contemplating to just ditch them and repurpose the old Sun V20z that is sitting in my basement rack, and move the hosting in-house, literally. My math goes as follows: my company pays up to $80 a months for my home internet service, which would cover the upgrade from currently Fios to Comcast business internet with 5 static IPs. So this comes free. running the server will cost me about $180/year at the current rate of approx. $.2/kWh my time is free So, it seems that the my net cost of doing this would be about $80 anually, plus the work that goes into setup and maintenance. I will have to get email hosting somewhere, which I do not want to do myself. On the other side of the balance sheet, I'd likely get better uptime than my provider based on recent stats, will not get suspended and don't have to spend hours with customer support. Overall, I am not convinced. Has anybody actually done that? What was your experience, and did it pay off?

  • Self-referencing anonymous closures: is JavaScript incomplete?

    - by Tom Auger
    Does the fact that anonymous self-referencing function closures are so prevelant in JavaScript suggest that JavaScript is an incomplete specification? We see so much of this: (function () { /* do cool stuff */ })(); and I suppose everything is a matter of taste, but does this not look like a kludge, when all you want is a private namespace? Couldn't JavaScript implement packages and proper classes? Compare to ActionScript 3, also based on EMACScript, where you get package com.tomauger { import bar; class Foo { public function Foo(){ // etc... } public function show(){ // show stuff } public function hide(){ // hide stuff } // etc... } } Contrast to the convolutions we perform in JavaScript (this, from the jQuery plugin authoring documentation): (function( $ ){ var methods = { init : function( options ) { // THIS }, show : function( ) { // IS }, hide : function( ) { // GOOD }, update : function( content ) { // !!! } }; $.fn.tooltip = function( method ) { // Method calling logic if ( methods[method] ) { return methods[ method ].apply( this, Array.prototype.slice.call( arguments, 1 )); } else if ( typeof method === 'object' || ! method ) { return methods.init.apply( this, arguments ); } else { $.error( 'Method ' + method + ' does not exist on jQuery.tooltip' ); } }; })( jQuery ); I appreciate that this question could easily degenerate into a rant about preferences and programming styles, but I'm actually very curious to hear how you seasoned programmers feel about this and whether it feels natural, like learning different idiosyncrasies of a new language, or kludgy, like a workaround to some basic programming language components that are just not implemented?

  • Collabnet Subversion and Self Signed Certificates

    - by Robert May
    We installed Collabnet as our subversion server recently.  This is the first time that we’ve used it.  In general, it seems pretty good, but we ran into a problem with it.  People were getting the following error in Tortoise: OPTIONS of ’https://xxxx.xxxxxxxx.xxxx/svn/xxxxx’: SSL handshake failed: SSL error code – 1/1/336032856 (https://xxxx.xxxxxxxx.xxxx) The odd thing is that for some people, it worked, for others, it didn’t!  I also couldn’t find anything useful out on the internet. We had checked the Subversion Server should serve via https option in the settings, and all of the ports were open, etc. This option causes a self signed certificate to be used. What we discovered: Tortoise must use the same url as is in the Hostname field on the General settings for collabnet or you’ll get this error.  Basically, some people were using https://svn.xxxxxxx.xxxxx and others were using https://computername.xxxxxxxx.xxxx.  Because the host name said used the computer name version, the whole thing broke.  By changing the host name to the svn version, which is what they should be using, the problem went away.  The users do get the “Accept Certificate” prompt, but we can live with that!

  • How can I use domain masking without having self referral in Google Analytics

    - by Cdore
    I have one old domain that points to a website's server's ip (let's call it www.oldsite.com). I have a new one, www.newsite.com, that is set up to be forwarded to a specific page on the website. Due to the way the host of newsite.com places the website in a frame, in Google Analystics, the newsite.com is listed as a source rather than the source they were at before hand, causing a self referral. A solution is to edit the code of the iframe as I looked up, but there's no way to really edit the host's masking source code of course. Another solution I did previously was have www.newsite.com point to the address that www.oldsite.come pointed to. It solved the analytics problems, but in exchange, the url masking no longer worked. In the address bar, it came up as www.oldsite.com. Is there a way to make me have url masking and be able to forward to agree with google analytics? The server of the website is hosted on a cloud server, if this is anymore information.

  • Self-imposed lockout from program

    - by Alex
    I'm plagued with a lack of willpower. I recently started looking for solutions, and came across a program for macs called SelfControl which completely blocks one's access to a given set of websites for a given period of time (you can delete the program/restart your computer/do almost anything and it will still block those sites for the specified time period, and doesn't require a password to do it.) Unfortunately, there are no windows analogues. The one that comes the closest is Cold Turkey. It has the functionality whereby you set a time in the future, specify a list of websites (or programs - eg explorer, firefox, chrome) and you are blocked from accessing them for the whole duration. No password can undo it, no system reboot, etc. The problem is that the program is a buggy piece of garbage, and in order to ensure that you're not locked out from websites forever, you have to run an uninstaller which is just an exe file accessible at any time which completely defeats the purpose of a self-imposed program lockout. I want to make a better version of that program, or find a simple way to prevent access to a given set of programs over a given period of time with no way around it. I've only taken a few introductory courses in java (math major), but the internet is really having a negative effect on my studies, and the only way I can do work is to eliminate all distractions. What do I need to learn in order to make a program with the following properties: Given a set of .exe files, and a time in the future , this program will prevent access to the given .exe files until current time = given time restarting the computer doesn't interfere with the program, one can't uninstall the program until current time = given time, one can't create another instance of the program to block itself I don't care how much programming knowledge i need to acquire in order to make this program, so please give me a specific list of things that I need to study in order to make this happen, or if something like this exists, then please let me know.

  • What is the proper way to handle non-tracking self tracking entities?

    - by Will
    Self tracking entities. Awesome. Except when you do something like return Db.Users; none of the self-tracking entities are tracking (until, possibly, they are deserialized). Fine. So we have to recognize that there is a possibility that an entity returning to us does not have tracking enabled. Now what??? Things I have tried For the given method body: using (var db = new Database()) { if (update.ChangeTracker.ChangeTrackingEnabled) db.Configurations.ApplyChanges(update); else FigureItOut(update, db); db.SaveChanges(); update.AcceptChanges(); } The following implementations of FigureItOut all fail: db.Configurations.Attach(update); db.DetectChanges(); Nor db.Configurations.Attach(update); db.Configurations.ApplyCurrentValues(update); Nor db.Configurations.Attach(update); db.Configurations.ApplyOriginalValues(update); Nor db.Configurations.Attach(update); db.Configurations.ApplyChanges(update Nor about anything else I can figure to throw at it, other than Getting the original entity from the database Comparing each property by hand Updating properties as needed What, exactly, am I supposed to do with self-tracking entities that aren't tracking themselves??

  • Python beginner having trouble running code

    - by Protean
    For some reason this code will not seem to run in the interpreter. When I hit F5 nothing happens, not even the debugger seems to recognize it. I assume it has something to do with the class, as when removed the interpreter seems to recognize the rest of the code. Please tell me what I am doing wrong. Edit: I have restarted the interpreter multiple times, any other piece of code I try to load runs fine, just this one is having trouble. print ('Why won't this work?') class sorting_class: def __init__(self): self.order = ['a', 'b', 'c', 'd'] self.globali = 0 self.orderi = 0 self.sortedlist = [] def sort(self, array): carry, leave = [] for arrayi in array: print ('run', arrayi) if self.order[self.orderi] == arrayi[self.globali]: carry.append(arrayi) else: if self.globali != 0: leave.append(arrayi) return carry, leave def srt(self, array): globalii = 0 carry, leave = my.sort(array) while len(self.sortedlist) != len(array): if len(self.carry) == 1: self.sortedlist.append(carry) arrayt = leave self.globali = 1 self.orderi = 0 carry, leave = my.sort(arrayt) elif len(self.carry) == 0: if len(self.leave) != 0: arrayt = leave self.globali = 1 self.orderi += 1 my.sort(arrayt) else: self.arrayt globalii += 1 self.orderi = globalii self.globali = 0 my.sort(arrayt) self.orderi = 0 else: arrayt = carry carry = [] self.globali += 1 carry, leave += my.sort(arrayt) my = sorting_class() x = ['ac', 'bc' ,'ab', 'da'] my.srt(x)

  • Code Golf: Shortest Turing-complete interpreter.

    - by ilya n.
    I've just tried to create the smallest possible language interpreter. Would you like to join and try? Rules of the game: You should specify a programming language you're interpreting. If it's a language you invented, it should come with a list of commands in the comments. Your code should start with example program and data assigned to your code and data variables. Your code should end with output of your result. It's preferable that there are debug statements at every intermediate step. Your code should be runnable as written. You can assume that data are 0 and 1s (int, string or boolean, your choice) and output is a single bit. The language should be Turing-complete in the sense that for any algorithm written on a standard model, such as Turing machine, Markov chains, or similar of your choice, it's reasonably obvious (or explained) how to write a program that after being executred by your interpreter performs the algorithm. The length of the code is defined as the length of the code after removal of input part, output part, debug statements and non-necessary whitespaces. Please add the resulting code and its length to the post. You can't use functions that make compiler execute code for you, such as eval(), exec() or similar.

  • python __getattr__ help

    - by Stefanos Tux Zacharakis
    Reading a Book, i came across this code... # module person.py class Person: def __init__(self, name, job=None, pay=0): self.name = name self.job = job self.pay = pay def lastName(self): return self.name.split()[-1] def giveRaise(self, percent): self.pay = int(self.pay *(1 + percent)) def __str__(self): return "[Person: %s, %s]" % (self.name,self.pay) class Manager(): def __init__(self, name, pay): self.person = Person(name, "mgr", pay) def giveRaise(self, percent, bonus=.10): self.person.giveRaise(percent + bonus) def __getattr__(self, attr): return getattr(self.person, attr) def __str__(self): return str(self.person) It does what I want it to do, but i do not understand the __getattr__ function in the Manager class. I know that it Delegates all other attributes from Person class. but I do not understand the way it works. for example why from Person class? as I do not explicitly tell it to. person(module is different than Person(class) Any help is highly appreciated :)
