  • Curating projects of deceased friends

    - by Ant
    A very good friend of mine, and an avid programmer, recently passed away. He left nearly 40 projects on BitBucket. Most of them are public, but a few of them are marked as private. I've decided to take on curation duties for the projects rather than leave his work to disappear. If you have been in the same situation, what did you do? Did you open-source everything? Continue development? Delete it all? I'm very interested to hear other people's experiences. There are a few reasons why some of the projects are marked as private (private projects on BitBucket are visible only to invited users and the original creator): One of them is an iOS web app that was free in the app store. I've had to remove the app from the store as I'm shutting down his web sites as a favour to his widow. However, I've already made the app public under the GPL v3 (he was a big GPL supporter). One of them contains proprietary code. It can't be open-sourced. Others are very much work-in-progress. I don't know if he intended to make them into hosted, paid services or if he wanted to give the code away under an open-source licence when they were finished. Here's a list of the private projects: Some kind of living cell simulator that uses SBML along with Runge-Kutta and Euler algorithms to do... something. There's a fair amount of code here but I don't know what it does or how far along it is. No docs. An accountacy application; it seems to have a solid DB design behind it but there's little code on top of that. A website whose purpose is to suggest good restaurants. Built on yii. Seems to have a lot of code but I'd need to set up a WAMP stack to see how far along it is. A website intended to host memorials to people who suffered from the same problem he was. Built on Joomla. I'm not sure how much of the code is just Joomla and how much is custom; again, I'd need to get Joomla running to find out. I'd just introduced him to Mercurial and BitBucket. All of the private projects are single commits of codebases he wasn't using version control with/was previously using SVN. I don't have the SVN repositories so I can't see the commit logs.

  • ODEE Green Field (Windows) Part 2 - WebLogic

    - by AndyL-Oracle
    Welcome back to the next installment on how to install Oracle Documaker Enterprise Edition onto a green field environment! In my previous post, I went over some basic introductory information and we installed the Oracle database. Hopefully you've completed that step successfully, and we're ready to move on - so let's dive in! For this installment, we'll be installing WebLogic 10.3.6, which is a prerequisite for ODEE 12.3 and 12.2. Prior to installing the WebLogic application server, verify that you have met the software prerequisites. Review the documentation – specifically you need to make sure that you have the appropriate JDK installed. There are advisories if you are using JDK 1.7. These instructions assume you are using JDK 1.6, which is available here. The first order of business is to unzip the installation package into a directory location. This procedure should create a single file, wls1036_generic.jar. Navigate to and execute this file by double-clicking it. This should launch the installer. Depending on your User Account Control rights you may need to approve running the setup application. Once the installer application opens, click Next. Select your Middleware Home. This should be within your ORACLE_HOME. The default is probably fine. Click Next. Uncheck the Email option. Click Yes. Click Next. Click Yes Click Yes and Yes again (yes, it’s quite circular). Check that you wish to remain uninformed and click Continue. Click Custom and Next. Uncheck Evaluation Database and Coherence, then click Next. Select the appropriate JDK. This should be a 64-bit JDK if you’re running a 64-bit OS. You may need to browse to locate the appropriate JAVA_HOME location. Check the JDK and click Next. Verify the installation directory and click Next. Click Next. Allow the installation to progress… Uncheck Run Quickstart and click Done.  And that's it! It's all quite painless - so let's proceed on to set up SOA Suite, shall we?

  • I want to start using TDD. Any tips for a beginner?

    - by Mike42
    I never used an automated test mechanism in any of my projects and I feel I'm missing a lot. I want to improve myself, so I have to start tackling some issues I've been neglecting like this and trying Git instead of being stuck on SVN. What's a good way to learn TDD? I'll probably be using Eclipse to program in Java. I've heard of JUnit, but I don't know if there's anything else I should consider.

  • Which devices is my app working on

    - by Woojah
    My team is developing an app that will work on about 100 (or more) different android devices. We are having trouble testing it since we are not sure how to verify if it works on all the different devices. Can anybody suggest some best practices, a testing framework, or some sort of way to give us feedback on how to test our app and/or get feedback from our users so they can tell us the problems they are having?

  • Error when trying to start Apache after installing SSL cert

    - by chris
    I am trying to install an SSL certificate, and I get the following errors: AH02241: Init: Unable to read server certificate from file /path/my.crt SSL Library Error: error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag SSL Library Error: error:0D07803A:asn1 encoding routines:ASN1_ITEM_EX_D2I:nested asn1 error (Type=X509) AH02312: Fatal error initialising mod_ssl, exiting. Here's the process I followed: I generated my private key with: openssl genrsa -out my.key 2048 I created the CSR with: openssl req -new -key my.key -out my.csr I provided the CSR to our IT department, and they returned a crt - it starts with -----BEGIN CERTIFICATE----- My ssl.conf has (my.example.com matches the Common name used during the generation of the CSR): <VirtualHost my.example.com:443> SSLEngine On ServerName my.example.com SSLCertificateFile /path/my.crt SSLCertificateKeyFile /path/my.key </VirtualHost> I do not have SSLCertificateChainFile or SSLCACertificate file set. The private key starts with ----BEGIN RSA PRIVATE KEY----- The csr starts with -----BEGIN CERTIFICATE REQUEST----- I have verified that both: openssl rsa -noout -modulus -in my.key openssl req -noout -modulus -in my.csr produce the same output. I cannot figure out how to verify the crt - trying both x509 and rsa produce an error. Should this process have worked? Can I verify that my.crt matches the key somehow?

  • How to set up the CNAME in DNS zone record to work with Unbounce

    - by Lirik
    I'm trying to run split testing on some landing pages I "designed" with Unbounce, but it requires that I set the CNAME record for my domain/sub-domain and I'm having trouble figuring out what is the right way to do it. My host is arvixe (www.arvixe.com) and their customer support has failed to help me for the past 5 days (I spoke to them multiple times). I followed the directions for setting the CNAME record and I was able to set the CNAME record, but I'm consistently unable to verify that the CNAME record is set up correctly. I followed the instructions on Unbounce to verify the CNAME record for my sub-domain (beta.devboost.com) and here are the results: No records found reverse lookup smtp diag port scan blacklist Reported by ns1.SNARE.arvixe.com on Thursday, November 10, 2011 at 5:49:57 PM (GMT-6) Here is my DNS zone record from the control panel of my host (last record, CNAME unbouncepages.com): Is there something wrong with my DNS Zone Record? What's the right way to do this? Update: I also have a CNAME record for beta in my root domain (devboost.com): I've updated my sub-domain record now: I've removed most of the other DNS records and I've removed the beta label for the CNAME record: Is that correct? Is there anything else I need to do?

  • How to avoid lftp Certificate verification error?

    - by pattulus
    I'm trying to get my Pelican blog working. It uses lftp to transfer the actual blog to ones server, but I always get an error: mirror: Fatal error: Certificate verification: subjectAltName does not match ‘blogname.com’ I think lftp is checking the SSL and the quick setup of Pelican just forgot to include that I don't have SSL on my FTP. This is the code in Pelican's Makefile: ftp_upload: $(OUTPUTDIR)/index.html lftp ftp://$(FTP_USER)@$(FTP_HOST) -e "mirror -R $(OUTPUTDIR) $(FTP_TARGET_DIR) ; quit" which renders in terminal as: lftp ftp://[email protected] -e "mirror -R /Volumes/HD/Users/me/Test/output /myblog_directory ; quit" What I managed so far is, denying the SSL check by changing the Makefile to: lftp ftp://$(FTP_USER)@$(FTP_HOST) -e "set ftp:ssl-allow no" "mirror -R $(OUTPUTDIR) $(FTP_TARGET_DIR) ; quit" Due to my incorrect implementation I get logged in correctly (lftp [email protected]:~>) but the one line feature doesn't work anymore and I have to enter the mirror command by hand: mirror -R /Volumes/HD/Users/me/Test/output/ /myblog_directory This works without an error and timeout. The question is how to do this with a one liner. In addition I tried: set ssl:verify-certificate/ftp.myblog.com no This trick to disable certificate verification in lftp: $ cat ~/.lftp/rc set ssl:verify-certificate no However, it seems there is no "rc" folder in my lftp directory - so this prompt has no chance to work.

  • curl FTPS with client certificate to a vsftpd

    - by weeheavy
    I'd like to authenticate FTP clients either via username+password or a client certificate. Only FTPS is allowed. User/password works, but while testing with curl (I don't have another option) and a client certificate, I need to pass a user. Isn't it technically possible to authenticate only by providing a certificate? vsftpd.conf passwd_chroot_enable=YES chroot_local_user=YES ssl_enable=YES rsa_cert_file=usrlocal/ssl/certs/vsftpd.pem force_local_data_ssl=YES force_local_logins_ssl=YES Tested with curl -v -k -E client-crt.pem --ftp-ssl-reqd ftp://server:21/testfile the output is: * SSLv3, TLS handshake, Client hello (1): * SSLv3, TLS handshake, Server hello (2): * SSLv3, TLS handshake, CERT (11): * SSLv3, TLS handshake, Request CERT (13): * SSLv3, TLS handshake, Server finished (14): * SSLv3, TLS handshake, CERT (11): * SSLv3, TLS handshake, Client key exchange (16): * SSLv3, TLS handshake, CERT verify (15): * SSLv3, TLS change cipher, Client hello (1): * SSLv3, TLS handshake, Finished (20): * SSLv3, TLS change cipher, Client hello (1): * SSLv3, TLS handshake, Finished (20): * SSL connection using DES-CBC3-SHA * Server certificate: * SSL certificate verify result: self signed certificate (18), continuing anyway. > USER anonymous < 530 Anonymous sessions may not use encryption. * Access denied: 530 * Closing connection #0 * SSLv3, TLS alert, Client hello (1): curl: (67) Access denied: 530 This is theoretically ok, as i forbid anonymous access. If I specify a user with -u username:pass it works, but it would without a certificate too. The client certificate seems to be ok, it looks like this: client-crt.pem -----BEGIN RSA PRIVATE KEY----- content -----END RSA PRIVATE KEY----- -----BEGIN CERTIFICATE----- content -----END CERTIFICATE----- What am I missing? Thanks in advance. (The OS is Solaris 10 SPARC).

  • Zscaler. Certs, cookies, and port 80 traffic

    - by 54's_lol
    So I work at HQ for a large company that shall remain nameless. We use Zscaler and I had to roll out a 2048 cert per zscaler's request. People around me at work dont understand the technology and think that the cert's are what is allowing internet connectivity. From my understanding(and please chime in) is the cookie located C:\Users\$$$$$$4$$\AppData\Roaming\Macromedia\Flash Player#SharedObjects\Q3JQJQJV\gateway.zscaler.net\zscaler.swf here that gets created when you provide your creds the first time you use the browser. The cert's are just simply a way of inspecting the SSL traffic as zscaler had no way of doing this before without them. They are essentially using the classic MITM attack to parse your SSL traffic. Gmail is smart enough to recognize this as you get a warning. My question is this, is there a product or service that I can use to verify my web browser when at home(I.E. off company network) isn't still getting routed to zscaler's cloud? If i do a tracert that will work fine. It's the port 80 and 443 web traffic zscaler and my company is after. I would like to verify that when I'm off their premise that my web traffic is using only my isp and the path to whatever content I'm searching for. Do the cert's i'm pushing and browser authentication do something behind the curtain that forces web traffic to get routed to zscaler? I searched quite a bit and would very much like to know if I'm ever off company scrutiny. I do know zscaler offers the service to force the scenario im asking about. Can I prove how my web traffic is getting routed? Thanks for any insight. I've been a fan for a long time and your guy's kung fu is very strong:-)

  • CVSROOT problem because of username string

    - by jatanp
    Hi, I have always been SVN user but currently I have to use CVS as the source repository. I am quite new to CVS and really got confused many a times (reason being I always tried to access CVS like SVN !) However now I am really stuck in one problem wherein I am not able to do any cvs operations through cygwin. Actually I have checked out the code using WinCVS and while doing that it created the CVSROOT as following, :pserver;username=<user_name>;password=<pwd>:<serverip>:/cvs/repository However whenever I try to use cvs command in cygwin (after setting CVSROOT variable using export) it fails with following error: cvs update: Unknown option (`username') in CVSROOT. cvs update: in directory .: cvs update: ignoring CVS/Root because it does not contain a valid root. cvs update: Unknown option (`username') in CVSROOT. cvs [update aborted]: Bad CVSROOT: `:pserver;username=<user_name>;password=<pwd>:<serverip>:/cvs/repository'. However the command works fine, if invoked through dos command prompt. I got to know that on DOS prompt, cvs command is provided by CVSNT whereas in cygwin it's some different package. Please let me know where I have made a mistake and how it can be corrected ! I need cvs to work inside cygwin for some scripting purpose.

  • Problems configuring an SSH tunnel to a Nexentastor appliance for use with headless Crashplan

    - by Rob Smallshire
    Problem I am attempting to configure an SSH tunnel to a NexentaStor appliance from either a Windows or Linux computer so that I can connect a Crashplan Desktop GUI to a headless Crashplan server running on the Nexenta box, according to these instructions on the Crashplan support site: Connect to a Headless CrashPlan Desktop. So far, I've failed to get a working SSH tunnel from from either either a Windows client (using Putty) or a Linux client (using command line SSH). I'm fairly sure the problem is at the receiving end with NexentaStor. A blog article - CrashPlan for Backup on Nexenta - indicates that it could be made to work only after "after enabling TCP forwarding in Nexenta in /etc/ssh/sshd_config" - although I'm not sure how to go about that or specifically what I need to do. Things I have tried Ensuring the Crashplan server on the Nexenta box is listening on port 4243 $ netstat -na | grep LISTEN | grep 42 127.0.0.1.4243 *.* 0 0 131072 0 LISTEN *.4242 *.* 0 0 65928 0 LISTEN Establishing a tunnel from a Linux host: $ ssh -L 4200:localhost:4243 admin:10.0.0.56 and then, from another terminal on the Linux host, using telnet to verify the tunnel: $ telnet localhost 4200 Trying ::1... Connected to localhost. Escape character is #^]'. with nothing more, although the Crashplan server should respond with something. From Windows, using PuTTY have followed the instructions on the Crashplan support site to establish an equivalent tunnel, but then telnet on Windows gives me no response at all and the Crashplan GUI can't connect either. The PuTTY log for the tunnelled connection shows reasonable output: ... 2011-11-18 21:09:57 Opened channel for session 2011-11-18 21:09:57 Local port 4200 forwarding to localhost:4243 2011-11-18 21:09:57 Allocated pty (ospeed 38400bps, ispeed 38400bps) 2011-11-18 21:09:57 Started a shell/command 2011-11-18 21:10:09 Opening forwarded connection to localhost:4243 but the telnet localhost 4200 command from Windows does nothing at all - it just waits with a blank terminal. On the NexentaStor server I've examined the /etc/ssh/sshd_config file and everything seems 'normal' - and I've commented out the ListenAddress entries to ensure that I'm listening on all interfaces. How can I establish a tunnel, and how can I verify that it is working?

  • openssl client authentication error: tlsv1 alert unknown ca: ... SSL alert number 48

    I've generated a certificate using openssl and place it on the client's machine, but when I try to connect to my server using that certificate, I error mentioned in the subject line back from my server.

  • Mplayer no sound when playing some movies

    - by Ivan Peevski
    Ok, that's a bit of a strange problem, that somehow crept into my system. It used to work fine. Here is the problem as far as I can identify it. When I try to play certain video files with mplayer, there is no sound. As far as I can tell, it is only an issue with ac3 and dts sound tracks (using the ffmpeg decoder). Mplayer says: ========================================================================== Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders AUDIO: 48000 Hz, 6 ch, s16le, 1536.0 kbit/33.33% (ratio: 192000->576000) Selected audio codec: [ffdca] afm: ffmpeg (FFmpeg DTS) ========================================================================== [AO_ALSA] Playback open error: Device or resource busy Failed to initialize audio driver 'alsa' Could not open/initialize audio device -> no sound. Audio: no sound (similar with ac3 sound, but using the ffac3 audio codec). Trying different audio output (-ao oss/pcm/sdl) doesn't fix the problem. The strange thing is that if I play these files directly with ffplay, they work fine. mplayer sound with mp3/ogg is fine My alsa configuration is standard (no /etc/asound.conf or ~/.asound*) OS: Linux Gentoo Mplayer: 1.0_rc4_p20100213 (SVN-r30554-4.3.4) FFMpeg: 0.5_p20601-r1 (SVN-r20601) Any other information I can provide?

  • LTO 2 tape performance in LTO 3 drive

    - by hmallett
    I have a pile of LTO 2 tapes, and both an LTO 2 drive (HP Ultrium 460e), and an autoloader with an LTO 3 drive in (Tandberg T24 autoloader, with a HP drive). Performance of the LTO 2 tapes in the LTO 2 drive is adequate and consistent. HP L&TT tells me that the tapes can be read and written at 64 MB/s, which seems in line with the performance specifications of the drive. When I perform a backup (over the network) using Symantec Backup Exec, I get about 1700 MB/min backup and verify speeds, which is slower, but still adequate. Performance of the LTO 2 tapes in the LTO 3 drive in the autoloader is a different story. HP L&TT tells me that the tapes can be read at 82 MB/s and written at 49 MB/s, which seems unusual at the write speed drop, but not the end of the world. When I perform a backup (over the network) using Symantec Backup Exec though, I get about 331 MB/min backup speed and 205 MB/min verify speeds, which is not only much slower, but also much slower for reads than for writes. Notes: The comparison testing was done on the same server, SCSI card and SCSI cable, with the same backup data set and the same tape each time. The tape and drives are error-free (according to HP L&TT and Backup Exec). The SCSI card is a U160 card, which is not normally recommended for LTO 3, but we're not writing to LTO 3 tapes at LTO 3 speeds, and a U320 SCSI card is not available to me at the moment. As I'm scratching my head to determine the reason for the performance drop, my first question is: While LTO drives can write to the previous generation LTO tapes, does doing so normally incur a performance penalty?
