  • What is the aim of software testing?

    - by user970696
    Having read many books, there is a basic contradiction: Some say, "the goal of testing is to find bugs" while other say "the goal of the testing is to equalize the quality of the product", meaning that bugs are its by-products. I would also agree that if testing would be aimed primarily on a bug hunt, who would do the actual verification and actually provided the information, that the software is ready? Even e.g. Kaner changed his original definiton of testing goal from bug hunting to quality assesement provision but I still cannot see the clear difference. I percieve both as equally important. I can verify software by its specification to make sure it works and in that case, bugs found are just by products. But also I perform tests just to brake things. Also what definition is more accurate?

  • Java, LDAP: Make it not ignore blank passwords?

    - by Steve
    I'm maintaining some legacy Java LDAP code. I know next to nothing about LDAP. The program below basically just sends the userid and password to the LDAP server, receives notification back if the credentials are good. If so, it prints out the LDAP attributes received from the LDAP server, if not it prints out an exception. All works well if a bad password is given. An "invalid credentials" exception gets thrown. However, if a blank password is sent to the LDAP Server, authentication will still happen, LDAP attributes will still be returned. Is this unhappy situation due to the LDAP server allowing blank passwords, or does the code below need to be adjusted such a blank password will get fed to the LDAP server in such a way so it will get rejected? I do have data validation in place. I took it off in a testing environment to solve another issue and noticed this problem. I would prefer not to have this problem underneath the data validation. Thanks much in advance for any information import javax.naming.*; import javax.naming.directory.*; import java.util.*; import java.sql.*; public class LDAPTEST { public static void main(String args[]) { String lcf = "com.sun.jndi.ldap.LdapCtxFactory"; String ldapurl = "ldaps://ldap-cit.smew.acme.com:636/o=acme.com"; String loginid = "George.Jetson"; String password = ""; DirContext ctx = null; Hashtable env = new Hashtable(); Attributes attr = null; Attributes resultsAttrs = null; SearchResult result = null; NamingEnumeration results = null; int iResults = 0; int iAttributes = 0; env.put(Context.INITIAL_CONTEXT_FACTORY, lcf); env.put(Context.PROVIDER_URL, ldapurl); env.put(Context.SECURITY_PROTOCOL, "ssl"); env.put(Context.SECURITY_AUTHENTICATION, "simple"); env.put(Context.SECURITY_PRINCIPAL, "uid=" + loginid + ",ou=People,o=acme.com"); env.put(Context.SECURITY_CREDENTIALS, password); try { ctx = new InitialDirContext(env); attr = new BasicAttributes(true); attr.put(new BasicAttribute("uid",loginid)); results = ctx.search("ou=People",attr); while (results.hasMore()) { result = (SearchResult)results.next(); resultsAttrs = result.getAttributes(); for (NamingEnumeration enumAttributes = resultsAttrs.getAll(); enumAttributes.hasMore();) { Attribute a = (Attribute)enumAttributes.next(); System.out.println("attribute: " + a.getID() + " : " + a.get().toString()); iAttributes++; }// end for loop iResults++; }// end while loop System.out.println("Records == " + iResults + " Attributes: " + iAttributes); }// end try catch (Exception e) { e.printStackTrace(); } }// end function main() }// end class LDAPTEST

  • Telerik OpenAccess ORM and the XML Metadata Source

    We all know that Telerik OpenAccess ORM has a completely new face with the Q1 2010 release so it is about time to start blogging about some of the features and improvements that the new Visual Designer brought along.  Today I will talk about one of the most notable changes in the new version of OpenAccess ORM and that is the XML only mapping. You all know that so far with the previous versions of the product the mapping information was defined by a mix of XML configuration files and CLR attributes. After a lot of customer feedback and thorough thought we decided to make the XML and the attributes as two separate and self-contained sources of metadata information about your model. You can choose one based on your personal preferences. I will start with a brief overview over the new XML mapping definition. Unlike previous versions, where all ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Looking for feedback on design pattern for simple 2D environment

    - by Le Mot Juiced
    I'm working in iOS. I am trying to make a very simple 2D environment where there are some basic shapes you can drag around with your finger. These shapes should interact in various ways when dropped on each other, or when single-tapped versus double-tapped, etc. I don't know the name for the design pattern I'm thinking of. Basically, you have a bunch of arrays named after attributes, such as "double-tappable" or "draggable" or "stackable". You assign these attributes to the shapes by putting the shapes in the arrays. So, if there's a double-tap event, the code gets the location of it, then iterates through the "double-tappable" array to see if any of its members are in that location. And so on: every interactive event causes a scan through the appropriate array or arrays. It seems like that should work, but I'm wondering if there's a better pattern for the purpose.

  • Classless tables possible with Datamapper?

    - by barerd
    I have an Item class with the following attributes: itemId,name,weight,volume,price,required_skills,required_items. Since the last two attributes are going to be multivalued, I removed them and create new schemes like: itemID,required_skill (itemID is foreign key, itemID and required_skill is primary key.) Now, I'm confused how to create/use this new table. Here are the options that came to my mind: 1) The relationship between Items and Required_skills is one-to-many, so I may create a RequiredSkill class, which belongs_to Item, which in turn has n RequiredSkills. Then I can do Item.get(1).requiredskills. This sounds most logical to me. 2) Since required_skills may well be thought of as constants (since they resemble rules), I may put them into a hash or gdbm database or another sql table and query from there, which I don't prefer. My question is: is there sth like a modelless table in datamapper, where datamapper is responsible from the creation and integrity of the table and allows me to query it in datamapper way, but does not require a class, like I may do it in sql?

  • Which MIME type to compress? and what If I omit the `type` attribute from the HTML?

    - by rockyraw
    Per my request, my webhost had turned mod_deflate ON. In my Cpanel I now have an "Optimize Website" button. Inside that menu I could either choose: "Compress all content" or "Compress the specified MIME types" with the following default MIME types: "text/html text/plain text/xml" Which option should I choose and why? If I choose option 2, which types should I add (is there a recommended list with the exact way they should be written)? According to Google recommendations, I have omitted the type="text/css" attributes from all CSS references, as well as the type="text/javascript" attributes from all script references. Would this hinder the "gzipping" process?

  • BSOD Before Windows Will Loads - Graphics Related

    - by Brian
    Alright deep breath here: (Windows 7 Home Premium 64 bit btw) Today I installed Star Craft 2 Beta. After trying to log in, it had some issues where it said my device stopped working (referring to my video device I have to imagine). After I force quit the game there were some random "hot" (various colors if i remember correctly) pixels on the screen. I decided to reboot and try again with similar results. I figured that maybe my display drivers could stand to be updated (I don't frequently update them as I don't often run into problems). I went out to nVidia's website and grabbed the latest drivers for Windows 7 64 bit GeForce 9 series. (I have SLi-ed 9800 GTs). Everything seemed to install fine and I performed the restart. This is when things went from bad (can't play SC2 beta ;) ) to worse (can't boot into windows!). Initially the very first splash screen - I think it's the bios splash screen - had lines of colored pixels covering it. It then displayed a screen that had lots of "(" on it. After that it showed the normal windows 7 splash screen as if it were going to load into Windows. Before getting much further, it BSODed on me. It was a 0x0000003B stop error. At nvlddmkm.sys. A little digging let verified that this was a problem with an nVidia graphics device, not a real shocker. Windows decided it would try to help me diagnose the problem, which it's only answer to was a System Restore, which did nothing to alleviate the problem. I was able to boot up fine in safe mode and was not able to roll back the driver, however I did uninstall the driver and reboot. I still had the graphical anomalies during the first two screens (same colored "."'s and weird "("'s), but there was NOT a stop error. Windows loaded up, found a default driver for the device and installed it and I restarted to let it load - and had yet another BSOD Stop error. Repeat driver uninstall, this time I reloaded the same version (I think it's possible that I was running a 32 bit version or a vista versus windows 7 version, but I don't have that information handy) of the nVidia driver from their website. Restart, same anomalies, same Stop Error. I am at a loss - At this point all I can think is that the firmware for the Video cards got fried or there's actual damage to the cards which I sincerely hope is not the case but the sooner I know the better. Any insight into what I might be able to do to troubleshoot/fix this problem would be most helpful. Attached below is a dump from DxDiag.

  • Problems with ipsec betwen Cisco ASA 5505 and Juniper ssg5

    - by Oskar Kjellin
    I am trying to set up an ipsec tunnel between our ASA 5505 and a Juniper ssg5. The tunnel is up and running, but I cannot get any data through it.

  • Proper 16:9 video size for non-HD 4:3 video (for youtube/vimeo)

    - by Xeoncross
    Since High Definition video came out on all the online sites it has changed the default aspect ratio of the player from 4:3 to 16:9. This means that for people posting SD video you have to resize some of your videos to get them to fit right. For example, NTSC DVD quality (aka 480i/p) is 720x480 pixels (width x height). However, low-end High Definition (720i/p) is 1280x720. Resolution Chart Anyway, now that the video players are built for HD you will find that uploading standard quality videos will result in videos that are "letter boxed" which means they have extra black bars on the top and bottom (or sides). Correct me if I'm wrong, but in order to get a 720x480 video to fit a box that is designed for HD the best practice would be to crop some of it off so that it fits as 720x404 since: 16/9 = 1.78 (1.7777777777778) 720/405 = 1.78 405x1.78 = 720.9 The same would stand for 640x480 (old TV quality) video that would need to be 640x360 correct? I'm asking because I'm not sure about all this and whether this is the proper way to fix these letter-boxing/display problems.

  • LASER x Deskjet Printer

    - by Mike
    I am about to buy a color printer. I had a b&W laserjet printer in the past but since then I use deskjet for decades. I need a printer that can deliver high quality as these photo deskjet printers but I am tired of paying ink that costs $9,000 per gallon of ink (1 gallon = 3.785 liters = 300 cartridges = $9,000). So, I was pondering about buying a color laser, but I am not sure if these printers can deliver the same quality and worth the investment in terms of toner consumption. I remembered that my old laserjet printer was able to print 1100 pages per toner cartridge. The deskjet printers I have can print 500 pages per cartridge. Price by price, 2 deskjet cartridges have more or less the same cost as one toner cartridge and in theory prints almost the same. I am not sure if this is true for color lasers. What you guys can tell me about quality, toner cost and cost per page using laser or deskjet. Does it worths the change? Remember that a deskjet printer costs $50 and a laser printer costs $200. thanks.

    Currently we're trying to set up an IPsec VPN between a Cisco ASA Version 8.0(4) and a CentOS Linux server.

  • How come my Intel 520 180GB SSD performs extremely poorly?

    - by Willem
    I recently installed a new Intel 520 series 180GB SSD in my brand new MacBook Pro. The system is as follows: Model: MacBook Pro 15-inch, Late 2011 (MacBookPro8,2) Processor: 2.4 GHz Intel Core i7 Memory: 16 GB 1333 MHz DDR3 Graphics: AMD Radeon HD 6770M 1024 MB Software: Mac OS X Lion 10.7.3 Main Drive Bay: Intel 520-series 180GB SATA-3 (6GB/s negotiated link) SSD (Firmware: 400i) [80GB free] Optical Bay: Toshiba 5400 RPM 750GB SATA-2 HDD Trim: Enabled (according to Trim Enabler App) And here are the speeds I'm getting: Read: 412 MB/s Write: 186 MB/s What have I done wrong? Results expected: Read/write both 500MB/s I have seen benchmarks with lesser SSD:s (SATA-2 even) outperform my write-speeds by far. Also, Intel 520 SSD:s are supposed to be the top class of SSD:s. Trim Enabler report: This looks a bit odd compared to screenshots from their site: These is the defined S.M.A.R.T attributes (taken from Intel): And here are my S.M.A.R.T attributes read using smartctl tool from smartmontools: They don't seem very compatible. I'm going to try and look for a S.M.A.R.T attributes reader tool for OS X which might support Intel 520 series.

  • Fix Video timelines

    - by Josh
    So, I have been going through and riping all of my DVD's and it seems that the way to get the highest quality out of these is to have DVD Shrink de-encrypt, rip, and decompress, the DVD's. After that I usually end up with a high quality (high size) set of .vob files in a classic DVD structure. Then I use a python script that I wrote to automate the process of finding the title sequence and then combining all of the title sequences' .vob files together into one file(similar to the "copy /b" command in windows), and then changing the extension to .mpg (a more widely supported format then .vob). This allows me to get a high quality rip in about 40 min. The problem comes in playing the files. I need all of the ripped dvd's to play on my media computer using windows media center but windows media center (and vlc for that matter) all think that the video files are anywhere from 5 min. to 0 min. which is not a problem (the video will still play all the way through) but if you want to pause it, when it is unpaused the video will start all the way over (Also fast forward and rewind don't work). I suspect that it is something wrong with the way the timeline is encoded in the video file, various forums on the internet recommended using virtualdub to fix the errors. But when I try to open the file virtual dub says that the file is not in mpeg-1 encoding and may be in mpeg-2. Is there any way to fix this? PS: I am aware that there was a similar question but it hasn't had any activity for 2 months and is dealing more with wmv files.

  • Optimal video resolution and encoding for recording games for YouTube?

    - by Rookie
    I want to record video from games, therefore I cannot use very large video resolution, but I still want to make the large video view to look as sharp as the original encoded video before upload. I tried to use YouTube's recommended 854x640 resolution, but it wasn't possible with h264 and the encoding software I used (Handbrake) converted it to a width of the nearest multiple of 4, which I think is a limitation of the h264 format. The video I encoded was sharp and fine quality, but when I uploaded it to YouTube, it lost a lot of quality and the preferred large video view looks almost as bad as a 320p video. I tried to wait a few days but it never got sharper (in case it didn't process it completely yet). So, which resolution and encoding options I should use, if I want the large video player to have the sharpest possible video, retaining the original video quality as good as possible? I noticed that recording with 640x480, the video was sharper than with 1280x720, so I'm not sure what im doing wrong here; both were h264. Is it anyhow possible to prevent YouTube from re-encoding the videos? I just wonder how people can make so sharp videos, while mine are all blurry after upload, but before upload they looked fine. I also tried YouTube's suggested bitrates with h264, but it didn't work any better.

  • Mavericks permission issues with Windows Server deduplicated shares

    - by dmohlmaster
    We have a number of 10.9-10.9.3 - Mavericks - machines installed throughout our facility. Much of the user content is pulled from shares stored on our Windows Server 2012 fileservers with deduplication enabled. I have found that files newly written or unoptimized are able to be accessed without issue - read, written, modified, etc. Once the file gets optomized/deduplicated and Windows adds the P & L attributes - sparse and symlink - the Macs running Mavericks begin to have access issues. Once the files get deduplicated, users begin receiving read access errors when copying files (see error1 below). This happens when copying to folders within the current folder tree or copying somewhere to the local system. If you 'stop' the copy operation and retry a few more times, it may eventually work for the specific instance but fail again later. I am however, able to copy these files without issue via the terminal. Other systems running 10.7 do not experience the same issues and are able to access file server resources without issue. Many of the systems having issues are newer and thus not able to be downgraded to 10.8 or 10.7. I have tried finder replacements such as Pathfinder but the results are the same. I know this is at least similar to the issues many Mac users are already experiencing and posting about but I haven't seen it directly linked to deduplication and the attributes written by Windows server. Has anyone seen this issue? Have any solutions been found? Error 1: When copying files after the PL attributes have been set by deduplication. "One or more items can't be copied to "Foler" because you don't have permissions to read them. ******************************************' Via the system.log, I am also seeing the following error when accessing these deduplicated file shares. The reparse point tag listed below is "IO_REPARSE_TAG_DEDUP" Reported error: "smbfs_nget: filename.ext - unknown reparse point tag 0x80000013"

  • Moving hidden files/folders with the command-line or batch-file

    - by Synetech
    Question Does anyone know of a way to move files and folders that have the hidden, system, or read-only attribute set from the command-line or a batch file? (No, stripping the attributes first is not an option since there is no practical way to know which attributes were set in order to re-set them after the move.) (Failed) Attempts Using the basic move command does not work with items with the hidden or system attribute set and for some reason, it does not have switches to specify attributes like the dir and del commands do. I tried using a utility I wrote that uses the shell’s file operation function, but that requires using start /w to prevent the batch file from running on ahead, and it complains about long-filename support for some reason. I tried using robocopy, but it first copies the files and then deletes the originals instead of simply moving the source (which results in a frustrating delay, even with the excessive output redirected to nul). (Surprisingly it seems that few people have ever needed to move hidden files from the command-line. All I could find was this one person who abandoned the attempt.)

  • How to convert JPEG JFIF files to JPEG Exif format?

    - by tigrou
    I recently put the SD card of my camera in a Windows 7 PC and start browsing pictures on it. I noticed some were not aligned correctly and use rotate feature included in Windows Photo Viewer in order to view them as I wanted. What I didn't know is that when rotate feature is used, it also overwrite the picture when pressing next or previous button resulting in a possible loss of quality (which is in my opinion a bad idea, app should at least warn user of what will happened when using such a feature). After that, I re-inserted the SD card back in my camera and bad surprise happened : the rotated picture could not be previewed anymore. Instead, i got a black screen saying "Incompatible JPEG format". Other files (untouched) are still working ok. To try to understand what happened I opened a JPEG file from camera and one generated on windows 7 in a hex editor. Here is the difference : The camera JPEG files have a Exif tag in them (with 0xE1 in header). Other JPEG files (Windows 7) have first a JFIF tag in it, followed by a Exif tag (with 0xE0 in header). So if i understand it well, both are JPEG files, but using a different internal format. Here is my question : is it possible (using some tool) to convert JFIF files to Exif format ? I understand that original camera files have been reencoded and thus lose some quality (getting originals back is impossible). What i want know if convert them from JFIF back to Exif (without a second loss of quality if possible...)

  • What is the bash syntax to create a new directory in the directory above?

    - by mozerella
    I aim to make a script for mogrify. The mogrify command will resize images in a directory and put the resized images into a directory on the same directory level, with the same name as the work directory, but with a suffix (_a). The new directory will be moved to another collection later on. Something like this, #!/bin/bash mkdir ../n_a for file in *{.JPG|.jpg}; do mogrify -path ../n_a -resize 1200x1200 -quality 96;done I'm guessing ../ denotes the parent dir when working in a child directory, but I need help here. Edit: "n" needs to be replaced with the syntax for the working directory name. Sorry there was a typo as well third script line, should have read n not x Edit2: This script does exactly what I need and it's silent. #!/bin/bash DEST="../${PWD##*/}_a" mkdir -p $DEST mogrify -path $DEST -resize 1200x1200 -quality 96 *.jpg *.JPG thanks to vgoff for the correct PWD syntax and cesareriva http://www.cesareriva.com/archives/722 for showing me the DEST function. Something else: ${PWD##*/}_a is not caring for spaces in the directory name and the script fails. An empty dir is created in the same dir as the images. Found it out now, it needs quotations on the $DEST too, presumably to help mkdir create the dir with a space in the name, and mogrify to write the files to the right place, like this #!/bin/bash DEST="../${PWD##*/}_a" mkdir -p "$DEST" mogrify -path "$DEST" -resize 1200x1200 -quality 96 *.jpg *.JPG

  • ASA 5505 VPN setup. VPN works but still unable to reach devices in the inside network.

    - by chickenloop
    I've setup a Remote Access VPN on my Cisco ASA 5505. I'm able to connect to my ASA via my phone or the Cisco client, but I'm unable to reach devices in my inside LAN when connected via VPN. The setup is the following: Inside Network : 10.0.0.0/24 VPN_POOL: 172.16.0.0/24 Outside Network: 192.168.1.0/24 ASA is not the perimeter router, there is another device on the 192.168.1.0/24 network which is connected to my cable provider. Obviously UDP port 500 and 4500 are forwarded to the ASA's outside interface. Everything works perfectly, besides the VPN stuff. Config: interface Vlan1 nameif inside security-level 100 ip address 10.0.0.254 255.255.255.0 interface Vlan2 description Outside Interface nameif outside security-level 0 address 192.168.1.254 255.255.255.0 object network VPNPOOL subnet 172.16.0.0 255.255.255.0 object network INSIDE_LAN subnet 10.0.0.0 255.255.255.0 Then the exempt NAT rule. nat (inside,outside) source static INSIDE_LAN INSIDE_LAN destination static VPNPOOL VPNPOOL I don't think that the problem is with the VPN config, as I can successfully establish the VPN connection, but just in case I post it here: group-policy ZSOCA_ASA internal group-policy ZSOCA_ASA attributes vpn-tunnel-protocol ikev1 split-tunnel-policy tunnelspecified split-tunnel-network-list value Split-Tunnel default-domain value default.domain.invalid tunnel-group ZSOCA_ASA type remote-access tunnel-group ZSOCA_ASA general-attributes address-pool VPNPOOL default-group-policy ZSOCA_ASA tunnel-group ZSOCA_ASA ipsec-attributes ikev1 pre-shared-key ***** Any ideas are welcome.
