  • MySQL Student database beginner SQL employment expectations

    - by sammysmall
    Background, Student pursuing BSIT degree, employer expectations, entry level. I would like to solicit opinions from this forum as to what your professional expectations are as regards an entry level position in working in the database realm... I see many job opportunities that require a minimum of 2 or more years experience, how does one go about obtaining this experience (I have tried very hard to maintain a minimum 3.70+ GPA) but have ZERO work experience in this field... I spend non school time working in VB and SQL to try and increase my proficiency. I have considered postponing my job search until I obtain certifications from brainbench etc... Any criticism and or advise is welcomed... Again I have no experience in database other than undergrad work in class. Thank you for your time sammysmall

    - by jonydep
    i have this in the superview: mySubView = [[MySubView alloc] init]; [self addSubview:mySubView]; [mySubView release]; then at some point later, in the sub view, this: [self removeFromSuperview]; when i debug it, i notice that the dealloc for the subview is never called, even though i'm fairly sure the reference count should be 0. any ideas why this might be? thanks.

    - by onurozcelik

  • iPad app store visibility

    - by Jameson
    So I created my iPad app and submitted it to the store, the app is called photogoo. I now have the iPad and I am finding that it is not possible to browse to the app in any way, confirmed by the zero downloads from yesterday. It is only possible to find by searching.. I also noticed that the apps in entertainment were being listed alphabetically and stopped at "F" Am I really being excluded because my app starts with the letter "P" or is it possible there is some reason that I am not being listed under "all apps"?

  • Java bitshift strangeness

    - by Martin
    Java has 2 bitshift operators for right shifts: >> shifts right, and is dependant on the sign bit for the sign of the result >>> shifts right and shifts a zero into leftmost bits http://java.sun.com/docs/books/tutorial/java/nutsandbolts/op3.html This seems fairly simple, so can anyone explain to me why this code, when given a value of -128 for bar, produces a value of -2 for foo: byte foo = (byte)((bar & ((byte)-64)) >>> 6); What this is meant to do is take an 8bit byte, mask of the leftmost 2 bits, and shift them into the rightmost 2 bits. Ie: initial = 0b10000000 (-128) -64 = 0b11000000 initial & -64 = 0b10000000 0b10000000 >>> 6 = 0b00000010 The result actually is -2, which is 0b11111110 Ie. 1s rather than zeros are shifted into left positions

  • is_tarfile() returns True for a blank file

    - by Zachary Young
    Hello all, I am testing some logic to handle a user uploading a TAR file. When I feed a blank file to tarfile.is_tarfile() it returns True, which is not what I am expecting: $ touch tartest $ cat tartest $ python -c "import tarfile; print tarfile.is_tarfile('tartest')" True If I add some text to the file, it returns False, which I am expecting: $ echo "not a tar" > tartest $ python -c "import tarfile; print tarfile.is_tarfile('tartest')" False I could add a check at the beginning to check for a zero-length file, but based on the documentation for tarfile.is_tarfile(name) I think this is unecessary: Return True if name is a tar archive file, that the tarfile module can read. I went so far as to check the source, tarfile.py, and I can see that it is checking header blocks but I do not fully understand how it is evaluating those blocks. Am I misreading the documentation and therefore setting unfair expectations? Thank you, Zachary

  • How to improve my Python regex syntax?

    - by FarmBoy
    I very new to Python, and fairly new to regex. (I have no Perl experience.) I am able to use regular expressions in a way that works, but I'm not sure that my code is particularly Pythonic or consise. For example, If I wanted to read in a text file and print out text that appears directly between the words 'foo' and 'bar' in each line (presuming this occurred one or zero times a line) I would write the following: fileList = open(inFile, 'r') pattern = re.compile(r'(foo)(.*)(bar)') for line in fileList: result = pattern.search(line) if (result != None): print result.groups()[1] Is there a better way? The if is necessary to avoid calling groups() on None. But I suspect there is a more concise way to obtain the matching String when there is one, without throwing errors when there isn't. I'm not hoping for Perl-like unreadability. I just want to accomplish this common task in the commonest and simplest way.

  • Django: Password protect photo url's?

    - by MikeN
    From my Django application I want to serve up secure photos. The photos are not for public consumption, I only want logged in users to have the ability to view them. I don't want to rely on obfuscated file id's (giving a photo a UUID of a long number) and count on that being hidden in my media folder. How would I store a photo securely on disk in my database and only stream it out to an authenticated session?

  • extract payload from tcpflow output

    - by Felipe Alvarez
    Tcpflow outputs a bunch of files, many of which are HTTP responses from a web server. Inside, they contain HTTP headers, including Content-type: , and other important ones. I'm trying to write a script that can extract just the payload data (i.e. image/jpeg; text/html; et al.) and save it to a file [optional: with an appropriate name and file extension]. The EOL chars are \r\n (CRLF) and so this makes it difficult to use in GNU distros (in my experiences). I've been trying something along the lines of: sed /HTTP/,/^$/d To delete all text from the the beginning of HTTP (incl) to the end of \r\n\r\n (incl) but I have found no luck. I'm looking for help from anyone with good experience in sed and/or awk. I have zero experience with Perl, please I'd prefer to use common GNU command line utilities for this Find a sample tcpflow output file here. Thanks, Felipe

  • Return number of matches from c# dictionary

    - by Rickard Haake
    Hello! I have a dictionary with non unique values and I want to count the matches of a string versus the values. Basically I now do dict.ContainsValue(a) to get a bool telling me if the string a exists in dict, but I want to know not only if it exists but how many times it exists (and maybee even get a list of the keys it exists bound to) Is there a way to do this using dictionary, or should I look for a different collection? /Rickard Haake

  • UITableView: moving a row into an empty section

    - by Frank C
    I have a UITableView with some empty sections. I'd like the user to be able to move a row into them using the standard edit mode controls. The only way I can do it so far is to have a dummy row in my "empty" sections and try to hide it by using tableView:heightForRowAtIndexPath: to give the dummy row a height of zero. This seems to leave it as a 1-pixel row. I can probably hide this by making a special type of cell that's just filled with [UIColor groupTableViewBackgroundColor], but is there a better way? This is all in the grouped mode of UITableView UPDATE: Looks like moving rows into empty sections IS possible without any tricks, but the "sensitivity" is bad enough that you DO need tricks in order to make it usable for general users (who won't be patient enough to slowly hover the row around the empty section until things click)

  • After playing a MediaElement, how can I play it again?

    - by Edward Tanguay
    I have a variable MediaElement variable named TestAudio in my Silverlight app. When I click the button, it plays the audio correctly. But when I click the button again, it does not play the audio. How can I make the MediaElement play a second time? None of the tries below to put position back to 0 worked: private void Button_Click_PlayTest(object sender, RoutedEventArgs e) { //TestAudio.Position = new TimeSpan(0, 0, 0); //TestAudio.Position = TestAudio.Position.Add(new TimeSpan(0, 0, 0)); //TestAudio.Position = new TimeSpan(0, 0, 0, 0, 0); //TestAudio.Position = TimeSpan.Zero; TestAudio.Play(); }

  • php if clause inside foreach not retrieving data correctly

    - by Mike
    Here's my issue: In my controller, I want to grab user input from a form. I then parse the input, and compare it to database values to ensure I'm grabbing the correct input. I simply want to match the user's answers to the question, grab the user ID, the question ID, and then determine if the answer applies to a multiple choice or checkbox question, or something else. I take those values and insert them into the answer table. Ignore the waiver stuff. I'll test that once I get the answers input correctly. // add answers and waiver consent records try { $answerArray = array(); $waiverArray = array(); // retrieve answers, waiver consents, and the question ID's from form object foreach ($formData as $key => $value) { $parts = explode("_", $key); if ($parts[0] == 'question') { array_push($answerArray, $value); } if ($parts[0] == 'waiverTitle') { array_push($waiverArray, $value); } } $questions = new Model_DbTable_Questions(); $questionResults = $questions->getQuestionResults($session->idEvent); foreach ( $questionResults as $qr ) { if ($qr ['questionType'] == 'multipleChoice' || $qr ['questionType'] == 'checkBox') { foreach ( $answerArray as $aa ) { $answerData = $answers->addAnswer ( $lastUserID, $qr ['idQuestion'], null, $aa ); echo count ( $answerData ) . ', ' . $qr ['questionType'] . ', ' . $aa . '<br />'; } } else { foreach ( $answerArray as $aa ) { $answerData = $answers->addAnswer ( $lastUserID, $qr ['idQuestion'], $aa, null ); echo count ( $answerData ) . ', ' . $qr ['questionType'] . ', ' . $aa . '<br />'; } } } } catch (Zend_Db_Statement_Exception $e) { $e->getMessage(); throw $e; } From my test data, I expect to get 2 records that match the multiple choice and checkbox criteria, and 1 record for text in the ELSE clause like this: 3, checkbox, 1 3, multipleChoice, 1 3, text, question_2 What I get is a 3x3 Cartesian product, 3 question elements each with the 3 possible answers like this output from the echo statements: 4, checkBox, 1 4, checkBox, 1 4, checkBox, question_2 4, multipleChoice, 1 4, multipleChoice, 1 4, multipleChoice, question_2 4, text, 1 4, text, 1 4, text, question_2 I've tried placing the IF clause inside the inner foreach, but I get the same results. I've been staring at this problem for way too long and cannot see what I'm doing wrong. Your kind assistance would be greatly appreciated. Please let me know if my request requires more clarification.

  • Winforms application hangs when switching to another app

    - by joseluisrod
    Hi, I believe I have a potential threading issue. I have a user control that contains the following code: private void btnVerify_Click(object sender, EventArgs e) { if (!backgroundWorkerVerify.IsBusy) { backgroundWorkerVerify.RunWorkerAsync(); } } private void backgroundWorkerVerify_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e) { VerifyAppointments(); } private void backgroundWorkerVerify_RunWorkerCompleted(object sender, System.ComponentModel.RunWorkerCompletedEventArgs e) { MessageBox.Show("Information was Verified.", "Verify", MessageBoxButtons.OK, MessageBoxIcon.Information); CloseEvent(); } vanilla code. but the issue I have is that when the application is running and the users tabs to another application when they return to mine the application is hung, they get a blank screen and they have to kill it. This started when I put the threading code. Could I have some rogue threads out there? what is the best way to zero in a threading problem? The issue can't be recreated on my machine...I know I must be missing something on how to dispose of a backgroundworker properly. Any thoughts are appreciated, Thanks, Jose
