  • Is it common practice to hire third parties to do code reviews for contractors?

    - by blueberryfields
    I recently observed some contract offers which included a "code review by third party" clause - the contract would not pay out fully until the code review was completed and it received a pass. I was surprised, especially considering that these were fairly simple, and small-scale contracts (churning out vanity apps for the iPhone). Is this kind of third-party code review a common thing to run into when contracting out as a programmer?

  • Konami Code on WordPress

    - by ninjaboi21
    Hey SuperUsers, I would love to get a Konami Code trigger on my WordPress blog, but I really have no idea how to implement it... For those of you who have no idea what Konami Code is, here is a link: http://en.wikipedia.org/wiki/Konami_Code It's a series of steps a user can use on a site and something pops up, user defined. What I would love to, is if someone tries the Konami Code on my website, everything shall fade away and some text shall appear instead. How do you do that? Here's an example of it: zeno.name Thanks in advance!

  • Code review process when using GIT as a repository?

    - by Sid
    What is the best process for code review when using GIT? Current process: We have a GIT server with a master branch to which everyone commits Devs work off the local master mirror or a local feature branch Devs commit to server's master branch Devs request code review on last commit Problem: Any bug in code review are already in master by the time it's caught. Worse, usually someone has burnt a few hours trying to figure out what happened... So, we would like To do code review BEFORE delivery into the 'master'. Have a process that works with a global team (no over the shoulder reviews!) something that doesn't require an individual dev to be at his desk/machine to be powered up so someone else can remote in (remove human dependency, devs go home at different timezones) We use TortoiseGIT for a visual representation of a list of files changed, diff'ing files etc. Some of us drop into a GIT shell when the GUI isn't enough, but ideally we'd like the workflow to be simple and GUI based (I want the tool to lift any burden, not my devs).

  • how to speed up the code??

    - by kaushik
    in my program i have a method which requires about 4 files to be open each time it is called,as i require to take some data.all this data from the file i have been storing in list for manupalation. I approximatily need to call this method about 10,000 times.which is making my program very slow? any method for handling this files in a better ways and is storing the whole data in list time consuming what is better alternatives for list? I can give some code,but my previous question was closed as that only confused everyone as it is a part of big program and need to be explained completely to understand,so i am not giving any code,please suggest ways thinking this as a general question... thanks in advance

  • Optimizing BeautifulSoup (Python) code

    - by user283405
    I have code that uses the BeautifulSoup library for parsing, but it is very slow. The code is written in such a way that threads cannot be used. Can anyone help me with this? I am using BeautifulSoup for parsing and than save into a DB. If I comment out the save statement, it still takes a long time, so there is no problem with the database. def parse(self,text): soup = BeautifulSoup(text) arr = soup.findAll('tbody') for i in range(0,len(arr)-1): data=Data() soup2 = BeautifulSoup(str(arr[i])) arr2 = soup2.findAll('td') c=0 for j in arr2: if str(j).find("<a href=") > 0: data.sourceURL = self.getAttributeValue(str(j),'<a href="') else: if c == 2: data.Hits=j.renderContents() #and few others... c = c+1 data.save() Any suggestions? Note: I already ask this question here but that was closed due to incomplete information.

  • Where is the bottleneck in this code?

    - by Mikhail
    I have the following tight loop that makes up the serial bottle neck of my code. Ideally I would parallelize the function that calls this but that is not possible. //n is about 60 for (int k = 0;k < n;k++) { double fone = z[k*n+i+1]; double fzer = z[k*n+i]; z[k*n+i+1]= s*fzer+c*fone; z[k*n+i] = c*fzer-s*fone; } Are there any optimizations that can be made such as vectorization or some evil inline that can help this code? I am looking into finding eigen solutions of tridiagonal matrices. http://www.cimat.mx/~posada/OptDoglegGraph/DocLogisticDogleg/projects/adjustedrecipes/tqli.cpp.html

  • Is "send us a page with code" a typical interview requirement?

    - by acm
    Recently I was asked to show "a page with code" for a job interview. Being mainly a back-end programmer, and that's the position I applied for, I first said to the person I was talking to exactly that: PHP is executed at the server and therefore not visible by just giving a "page". However, following their desire, I sent links to the pages I've worked on before. Obviously they couldn't see anything except for the HTML, CSS, JS... They said it was not enough, they could not see the PHP. Understanding that they probably just wanted to know my skills and/or interest I sent them my Stack Overflow profile. Among all my questions and answers, most of them with code, certainly the PHP is there. But it seems this is not what they wanted. Well, I don't have any code put together that I can simply publish for someone to see. And I would never do it for the code I have deployed, obviously. So my question is/are: What does "send us a page with code" mean? What should I send? Is this a typical interview requirement?

  • How to verify the code that could take a substantial time to compile? [on hold]

    - by user18404
    As a follow up to my prev question: What is the best aproach for coding in a slow compilation environment To recap: I am stuck with a large software system with which a TDD ideology of "test often" does not work. And to make it even worse the features like pre-compiled headers/multi-threaded compilation/incremental linking, etc is not available to me - hence I think that the best way out would be to add the extensive logging into the system and to start "coding in large chunks", which I understand as code for a two-three hours first (as opposed to 15-20 mins in TDD) - thoroughly eyeball the code for a 15 minutes and only after all that do the compilation and run the tests. As I have been doing TDD for a quite a while, my code eyeballing / code verification skills got rusty (you don't really need this that much if you can quickly verify what you've done in 5 seconds by running a test or two) - so I am after a recommendations on how to learn these source code verification/error spotting skills again. I know I was able to do that easily some 5-10 years ago when I din't have much support from the compiler/unit testing tools I had until recently, thus there should be a way to get back to the basics.

  • Would there be any reason not to use github (or any open source hosting site) for my code?

    - by Jetti
    So I just created my first github repo and started to wonder if there would be any reason why somebody shouldn't post their code. I don't mean the obvious, such as code that is IP of somebody else or any other possible legal situation; I'm talking about a newbie posting their own, albeit terrible, code. I've heard several times on this site that one of the things that a some of the hiring managers do is check out the person on Github (or similar site), so what if the code is lacking? Would the position desired matter? (ex Junior Developer vs Senior)?

  • How to make code-review feel less like a way to *shift* the responsibility? [duplicate]

    - by One Two Three
    This question already has an answer here: How do you make people accept code review? 33 answers Sometimes it seems to me that people ask for code-reviews just so they would be able to say "Xyz reviewed my code!"(1) when something broke. Question, is that ever the case? (Or is it just my imagination) If it is, how do I handle this? (1): What s/he really meant: It's Xyz's fault or something along those lines.

  • Optimizing Python code with many attribute and dictionary lookups

    - by gotgenes
    I have written a program in Python which spends a large amount of time looking up attributes of objects and values from dictionary keys. I would like to know if there's any way I can optimize these lookup times, potentially with a C extension, to reduce the time of execution, or if I need to simply re-implement the program in a compiled language. The program implements some algorithms using a graph. It runs prohibitively slowly on our data sets, so I profiled the code with cProfile using a reduced data set that could actually complete. The vast majority of the time is being burned in one function, and specifically in two statements, generator expressions, within the function: The generator expression at line 202 is neighbors_in_selected_nodes = (neighbor for neighbor in node_neighbors if neighbor in selected_nodes) and the generator expression at line 204 is neighbor_z_scores = (interaction_graph.node[neighbor]['weight'] for neighbor in neighbors_in_selected_nodes) The source code for this function of context provided below. selected_nodes is a set of nodes in the interaction_graph, which is a NetworkX Graph instance. node_neighbors is an iterator from Graph.neighbors_iter(). Graph itself uses dictionaries for storing nodes and edges. Its Graph.node attribute is a dictionary which stores nodes and their attributes (e.g., 'weight') in dictionaries belonging to each node. Each of these lookups should be amortized constant time (i.e., O(1)), however, I am still paying a large penalty for the lookups. Is there some way which I can speed up these lookups (e.g., by writing parts of this as a C extension), or do I need to move the program to a compiled language? Below is the full source code for the function that provides the context; the vast majority of execution time is spent within this function. def calculate_node_z_prime( node, interaction_graph, selected_nodes ): """Calculates a z'-score for a given node. The z'-score is based on the z-scores (weights) of the neighbors of the given node, and proportional to the z-score (weight) of the given node. Specifically, we find the maximum z-score of all neighbors of the given node that are also members of the given set of selected nodes, multiply this z-score by the z-score of the given node, and return this value as the z'-score for the given node. If the given node has no neighbors in the interaction graph, the z'-score is defined as zero. Returns the z'-score as zero or a positive floating point value. :Parameters: - `node`: the node for which to compute the z-prime score - `interaction_graph`: graph containing the gene-gene or gene product-gene product interactions - `selected_nodes`: a `set` of nodes fitting some criterion of interest (e.g., annotated with a term of interest) """ node_neighbors = interaction_graph.neighbors_iter(node) neighbors_in_selected_nodes = (neighbor for neighbor in node_neighbors if neighbor in selected_nodes) neighbor_z_scores = (interaction_graph.node[neighbor]['weight'] for neighbor in neighbors_in_selected_nodes) try: max_z_score = max(neighbor_z_scores) # max() throws a ValueError if its argument has no elements; in this # case, we need to set the max_z_score to zero except ValueError, e: # Check to make certain max() raised this error if 'max()' in e.args[0]: max_z_score = 0 else: raise e z_prime = interaction_graph.node[node]['weight'] * max_z_score return z_prime Here are the top couple of calls according to cProfiler, sorted by time. ncalls tottime percall cumtime percall filename:lineno(function) 156067701 352.313 0.000 642.072 0.000 bpln_contextual.py:204(<genexpr>) 156067701 289.759 0.000 289.759 0.000 bpln_contextual.py:202(<genexpr>) 13963893 174.047 0.000 816.119 0.000 {max} 13963885 69.804 0.000 936.754 0.000 bpln_contextual.py:171(calculate_node_z_prime) 7116883 61.982 0.000 61.982 0.000 {method 'update' of 'set' objects}

  • Good way to backup code projects

    - by rkmax
    I work as a developer, and I have many projects for most of them use GIT for versioning the code, I have some projects that are not code such as interfaces sketches, idea, etc.. currently I have a disorder with the backups before Dejadup used, but the downside comes when I want to restore my backups from Windows. Periodically change of operating system (Windows or Linux). my question is which is better, copy each folder (project) directly to my external disk or create a repository (git - bare init) for each project I need or should do?

  • Multiline code in Word 2007

    - by WaelJ
    I am using word 2007 and am inserting code into the document. I have a style with a fixed-width font and light grey background and all, and I use Notepad++ for syntax highlighting. My problem is with a "line" of code that is too long to display, so is there a way to auto-insert an arrow symbol at the beginning of a such lines to indicate that it is the same line (kind of like hyphenating, except on long lines instead of long words) So for e.g. something like this: public static void foo(String abcdefg, Boolean 123, ?String xyz)

  • What is a good program for storing "chunks" of commonly used source code

    - by Rob Wiley
    I've looked at CodeLocker (poorly styled and relatively unflexible, but free) and Source Code Library (Overzone software - very nicely styled, looks flexible, but very expensive - $80). Ideally, I'm looking for a relatively simple, inexpensive program (not an online website) that I can save text data (source code) with a title and keywords, maybe even a description. It would also have some type of search functionality.

  • Inline code from iPhone keyboard [closed]

    - by lc
    When I'm writing a post here or on any of the sister sites (especially SO), I want to use the backquote for inline code blocks. Now, as far as it looks, there doesn't seem to be a backquote (backtick) on the iPhone keyboard. Under the single quote key, I've found two curly/angled quotes, but those (’ and ‘) don't seem to do the trick... So, how do I create an inline code block from iPhone/Safari?

  • [Python] Tips for making a fraction calculator code more optimized (faster and using less memory)

    - by Logic Named Joe
    Hello Everyone, Basicly, what I need for the program to do is to act a as simple fraction calculator (for addition, subtraction, multiplication and division) for the a single line of input, for example: -input: 1/7 + 3/5 -output: 26/35 My initial code: import sys def euclid(numA, numB): while numB != 0: numRem = numA % numB numA = numB numB = numRem return numA for wejscie in sys.stdin: wyjscie = wejscie.split(' ') a, b = [int(x) for x in wyjscie[0].split("/")] c, d = [int(x) for x in wyjscie[2].split("/")] if wyjscie[1] == '+': licz = a * d + b * c mian= b * d nwd = euclid(licz, mian) konA = licz/nwd konB = mian/nwd wynik = str(konA) + '/' + str(konB) print(wynik) elif wyjscie[1] == '-': licz= a * d - b * c mian= b * d nwd = euclid(licz, mian) konA = licz/nwd konB = mian/nwd wynik = str(konA) + '/' + str(konB) print(wynik) elif wyjscie[1] == '*': licz= a * c mian= b * d nwd = euclid(licz, mian) konA = licz/nwd konB = mian/nwd wynik = str(konA) + '/' + str(konB) print(wynik) else: licz= a * d mian= b * c nwd = euclid(licz, mian) konA = licz/nwd konB = mian/nwd wynik = str(konA) + '/' + str(konB) print(wynik) Which I reduced to: import sys def euclid(numA, numB): while numB != 0: numRem = numA % numB numA = numB numB = numRem return numA for wejscie in sys.stdin: wyjscie = wejscie.split(' ') a, b = [int(x) for x in wyjscie[0].split("/")] c, d = [int(x) for x in wyjscie[2].split("/")] if wyjscie[1] == '+': print("/".join([str((a * d + b * c)/euclid(a * d + b * c, b * d)),str((b * d)/euclid(a * d + b * c, b * d))])) elif wyjscie[1] == '-': print("/".join([str((a * d - b * c)/euclid(a * d - b * c, b * d)),str((b * d)/euclid(a * d - b * c, b * d))])) elif wyjscie[1] == '*': print("/".join([str((a * c)/euclid(a * c, b * d)),str((b * d)/euclid(a * c, b * d))])) else: print("/".join([str((a * d)/euclid(a * d, b * c)),str((b * c)/euclid(a * d, b * c))])) Any advice on how to improve this futher is welcome. Edit: one more thing that I forgot to mention - the code can not make use of any libraries apart from sys.

Like the RTL mapping for memory related operations which is done in a compiler at the time of target code generation, where and how exactly is the same done for io operations? How are the appeoaches different for processors supporting MMIO and I/O mapped I/O? Are there any optimizations done for the io operations in compilers?

  • How to simply this logic/code?

    - by Tattat
    I want to write an apps that accepts user command. The user command is used in this format: command -parameter For example, the app can have "Copy", "Paste", "Delete" command I am thinking the program should work like this : public static void main(String args[]){ if(args[0].equalsIgnoreCase("COPY")){ //handle the copy command } else if(args[0].equalsIgnoreCase("PASTE")){ //handle the copy command }/** code skipped **/ } So, it works, but I think it will become more and more complex when I have more command in my program, also, it is different to read. Any ideas to simply the logic?
