• Running 12.04 as a gateway - resolvconf, dhclient and dnsmasq integration

  - by Adam

  I have a gateway server which is set up originally with Ubuntu desktop 12.04 - perhaps a mistake, I don't know, something to bear in mind. I ripped out network-manager and now want to get resolvconf, dhclient and dnsmasq to play well together. dhclient gets the gateway's eth0 WAN ip address and the ISP DNS name server from the modem. dnsmasq needs to serve dhcp to the rest of the lan on eth1 and acts as a DNS cache both for the lan and for the gateway machine. I also set up iptables as a firewall. Right now, the gateway's /etc/resolv.conf shows only name server = 127.0.0.1 which is correct AFAIK. However I don't think that dhclient is giving dnsmasq the ISP DNS name server nor is dnsmasq picking up the OpenDNS and Google name servers I specified in /etc/network/interfaces - at the moment look-ups, i.e. ping or surfing, don't work unless I manually edit /etc/resolv.conf to put in an upstream name server like 8.8.8.8 So I removed the resolvconf package. Now I'm not getting dhcp on my lan and I'm not able to do DNS look-ups on the host itself - I can surf and ping on the net, but not 127.0.0.1. Where do I go from here? This setup with the config for dhclient and dnsmasq, and the same resolv.conf and hosts files worked on my old debian box.

• How to get a Sun Ray to load a firmware from elsewhere

  - by vdiozguy

  I run a Sun Ray/VDI demo environment internally within the company - and because it's not a public service, I need to tell my Sun Rays to connect to it directly so that I don't get redirected to the corporate servers. To get any new Sun Ray to connect to *my* setup I usually pull out my laptop so that the Sun Ray can load the new version of the F/W along with the permission to pull up the management GUI via STOP-S.But there is a better way if you have another Sun Ray server handy:1) allow your Sun Ray to connect to the default corporate server2) log in to a "regular" session, that is a Solaris or Linux desktop on the Sun Ray server itself3) in a terminal, utswitch to your server (/opt/SUNWut/bin/utswitch -h myserver)4) again, login to a regular session there5) in a terminal,  issue "/opt/SUNWut/lib/utload -S myserver -w"6) Watch your firmware load and wait7) the Sun Ray will reboot and connect to the first server again. Repeat steps 2-48) issue "/opt/SUNWut/lib/utload -S myserver -f SunRay.enableGUI"9) Press STOP-S and be merryNOTE: I'm sure there is even yet a better way - this is totally unsupported, most likely a figment of my imagination. In any case, this post will self-destruct in BOOM.

• Oracle Enterprise Manager 12c Configuration Best Practices (Part 3 of 3)

  - by Bethany Lapaglia

  <span id="XinhaEditingPostion"></span>&amp;lt;span id=&amp;quot;XinhaEditingPostion&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; This is part 3 of a three-part blog series that summarizes the most commonly implemented configuration changes to improve performance and operation of a large Enterprise Manager 12c environment. A “large” environment is categorized by the number of agents, targets and users. See the Oracle Enterprise Manager Cloud Control Advanced Installation and Configuration Guide chapter on Sizing for more details on sizing your environment properly. Part 1 of this series covered recommended configuration changes for the OMS and Repository Part 2 covered recommended changes for the Weblogic server Part 3 covers general configuration recommendations and a few known issues The entire series can be found in the My Oracle Support note titled Oracle Enterprise Manager 12c Configuration Best Practices [1553342.1]. Configuration Recommendations Configure E-Mail Notifications for EM related Alerts In some environments, the notifications for events for different target types may be sent to different support teams (i.e. notifications on host targets may be sent to a platform support team). However, the EM application administrators should be well informed of any alerts or problems seen on the EM infrastructure components. Recommendation: Create a new Incident rule for monitoring all EM components and setup the notifications to be sent to the EM administrator(s). The notification methods available can create or update an incident, send an email or forward to an event connector. To setup the incident rule set follow the steps below. Note that each individual rule in the rule set can have different actions configured. 1.  To create an incident rule for monitoring the EM components, click on Setup / Incidents / Incident Rules. On the All Enterprise Rules page, click on the out-of-box rule called “Incident management Ruleset for all targets” and then click on the Actions drop down list and select “Create Like Rule Set…” 2. For the rule set name, enter a name such as MTM Ruleset. Under the Targets tab, select “All targets of types” and select “OMS and Repository” from the drop down list. This target type contains all of the key EM components (OMS servers, repository, domains, etc.) 3. Click on the Rules tab. To edit a rule, click on the rule name and click on Edit as seen below 4. Modify the following rules: a. Incident creation Rule for metric alerts i. Leave the Type set as is but change the Severity to add Warning by clicking on the drop down list and selecting “Warning”. Click Next. ii.  Add or modify the actions as required (i.e. add email notifications). Click Continue and then click Next. iii. Leave the Name and description the same and click Next. iv. Click Continue on the Review page. b. Incident creation Rule for target unreachable. i.   Leave the Type set as is but change the Target type to add OMS and Repository by clicking on the drop down list selecting “OMS and Repository”. Click Next. ii.  Add or modify the actions as required (i.e. add email notifications) Click Continue and then click Next. iii. Leave the Name and description the same and click Next. iv. Click Continue on the Review page. 5.  Modify the actions for any other rule as required and be sure to click the “Save” push button to save the rule set or all changes will be lost. Configure Out-of-Band Notifications for EM Agent Out-of-Band notifications act as a backup when there’s a complete EM outage or a repository database issue. This is configured on the agent of the OMS server and can be used to send emails or execute another script that would create a trouble ticket. It will send notifications about the following issues: • Repository Database down • All OMS are down • Repository side collection job that is broken or has an invalid schedule • Notification job that is broken or has an invalid schedule Recommendation: To setup Out-of-Band Notifications, refer to the MOS note “How To Setup Out Of Bound Email Notification In 12c” (Doc ID 1472854.1) Modify the Performance Test for the EM Console Service The EM Console Service has an out-of-box defined performance test that will be run to determine the status of this service. The test issues a request via an HTTP method to a specific URL. By default, the HTTP method used for this test is a GET but for performance reasons, should be changed to HEAD. The URL used for this request is set to point to a specific OMS server by default. If a multi-OMS system has been implemented and the OMS servers are behind a load balancer, then the URL in this section must be modified to point to the load balancer name instead of a specific server name. If this is not done and a portion of the infrastructure is down then the EM Console Service will show down as this test will fail. Recommendation: Modify the HTTP Method for the EM Console Service test and the URL if required following the detailed steps below. 1.  To create an incident rule for monitoring the EM components, click on Targets / Services. From the list of services, click on the EM Console Service. 2. On the EM Console Service page, click on the Test Performance tab. 3.  At the bottom of the page, click on the Web Transaction test called EM Console Service Test 4.  Click on the Service Tests and Beacons breadcrumb near the top of the page. 5.  Under the Service Tests section, make sure the EM Console Service Test is selected and click on the Edit push button. 6.  Under the Transaction section, make sure the Access Logout page transaction is selected and click on the Edit push button 7) Under the Request section, change the HTTP Method from the default of GET to the recommended value of HEAD. The URL in this section must be modified to point to the load balancer name instead of a specific server name if multi-OMSes have been implemented. Check for Known Issues Job Purge Repository Job is Shown as Down This issue is caused after upgrading EM from 12c to 12cR2. On the Repository page under Setup ? Manage Cloud Control ? Repository, the job called “Job Purge” is shown as down and the Next Scheduled Run is blank. Also, repvfy reports that this is a missing DBMS_SCHEDULER job. Recommendation: In EM 12cR2, the apply_purge_policies have been moved from the MGMT_JOB_ENGINE package to the EM_JOB_PURGE package. To remove this error, execute the commands below: $ repvfy verify core -test 2 -fix To confirm that the issue resolved, execute $ repvfy verify core -test 2 It can also be verified by refreshing the Job Service page in EM and check the status of the job, it should now be Up. Configure the Listener Targets in EM with the Listener Password (where required) EM will report this error every time it is encountered in the listener log file. In a RAC environment, typically the grid home and rdbms homes are owned by different OS users. The listener always runs from the grid home. Only the listener process owner can query or change the listener properties. The listener uses a password to allow other OS users (ex. the agent user) to query the listener process for parameters. EM has a default listener target metric that will query these properties. If the agent is not permitted to do this, the TNS incident (TNS-1190) will be logged in the listener’s log file. This means that the listener targets in EM also need to have this password set. Not doing so will cause many TNS incidents (TNS-1190). Below is a sample of this error from the listener log file: Recommendation: Set a listener password and include it in the configuration of the listener targets in EM For steps on setting the listener passwords, see MOS notes: 260986.1 , 427422.1

• Can't complete dropbox installation from behind proxy

  - by Mark Jones

  Problem: My PC on campus sits behind a proxy (requiring authentication) and I can't setup Dropbox. I am convinced that this is a proxy issue as I can't setup Ubuntu one either (but I don't use Ubuntu One so that is not a problem). I have looked at the Ubuntu One fix but it seems to be to modify settings explicitly related to Ubuntu One. I can install the nautilus-dropbox package (compiled from source and from .deb package from website and from software centre) but once I click OK from the "Dropbox Installation" dialog box (prompting me to download the proprietary daemon) the installation just freezes with the OK button pressed. When I look at its process in System Monitor its waiting channel is inet_wait_for_connect. I have set the following proxy directives thus far: Added mj22:**@proxy.waikato.ac.nz:80 information to network proxy settings under network in settings. Added http_host and http_port variables under gconf-editor-system-proxy Added 'host', 'authentication_password' 'authentication_user' and ticked 'user authentication' and 'use_http_proxy' under gconf-editor-system-http_proxy Added export http_proxy="http://mj22:**@proxy.waikato.ac.nz:80/" to /etc/bash.bashrc Added Acquire::http::proxy "http://mj22:**@proxy.waikato.ac.nz:80/"; to /etc/apt/apt.conf (which is what I imagine is letting Software Center retrieve packages). (where ** is my password) I have also added the equivalent ftp and https lines for the above entries. I get the internet fine and Software Centre can download packages but thats it. Related issues: The software centre can't fetch reviews (but can download packages). When trying to add an online account in Gnome 3 a dialog pop up appears with "Error getting a Request Token: Cannot connect to proxy (proxy.waikato.ac.nz)" Updates: After some time (10mins ish) Dropbox shows an error dialog box that reads: Trouble connecting to Dropbox servers. Maybe your internet connection is down, or you need to set you http_proxy environment variable. Is there a way I can see what environment variables are currently set?

• What are the packages/libraries I should install before compiling Python from source?

  - by Lennart Regebro

  Once in a while I need to install a new Ubuntu (I used it both for desktop and servers) and I always forget a couple of libraries I should have installed before compiling, meaning I have to recompile, and it's getting annoying. So now I want to make a complete list of all library packages to install before compiling Python (and preferably how optional they are). This is the list I compiled with below help and by digging in setup.py. It is complete for Ubuntu 10.04 and 11.04 at least: build-essential (obviously) libz-dev (also pretty common and essential) libreadline-dev (or the Python prompt is crap) libncursesw5-dev libssl-dev libgdbm-dev libsqlite3-dev libbz2-dev More optional: tk-dev libdb-dev Ubuntu has no packages for v1.8.5 of the Berkeley database, nor (for obvious reasons) the Sun audio hardware, so the bsddb185 and sunaudiodev modules will still not be built on Ubuntu, but all other modules are built with the above packages installed. Python 2.5 and Python 2.6 also needs to have LDFLAGS set on Ubuntu 11.04 and later, to handle the new multi-arch layout: export LDFLAGS="-L/usr/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH)" For Python 2.6 and 2.7 you also need to explicitly enable SSL after running the ./configure script and before running make. In Modules/Setup there are lines like this: #SSL=/usr/local/ssl #_ssl _ssl.c \ # -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ # -L$(SSL)/lib -lssl -lcrypto Uncomment these lines and change the SSL variable to /usr: SSL=/usr _ssl _ssl.c \ -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ -L$(SSL)/lib -lssl -lcrypto Python 2.6 also needs Modules/_ssl.c modified to be used with OpenSSL 1.0, which is used in Ubuntu 11.10. At around line 300 you'll find this: else if (proto_version == PY_SSL_VERSION_SSL3) self->ctx = SSL_CTX_new(SSLv3_method()); /* Set up context */ else if (proto_version == PY_SSL_VERSION_SSL2) self->ctx = SSL_CTX_new(SSLv2_method()); /* Set up context */ else if (proto_version == PY_SSL_VERSION_SSL23) self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */ Change that into: else if (proto_version == PY_SSL_VERSION_SSL3) self->ctx = SSL_CTX_new(SSLv3_method()); /* Set up context */ #ifndef OPENSSL_NO_SSL2 else if (proto_version == PY_SSL_VERSION_SSL2) self->ctx = SSL_CTX_new(SSLv2_method()); /* Set up context */ #endif else if (proto_version == PY_SSL_VERSION_SSL23) self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */ This disables SSL_v2 support, which apparently is gone in OpenSSL1.0.

• Hot fix published for TFS2010 upgrade issues

  - by jehan

  Microsoft has released a hot fix for the issues that are identified after the migration of TFS2005/TFS2008 servers to TFS2010. The issues are related to Merging and Labels: ·         Labels that were created before the upgrade are entirely empty.  Labels could be also have incorrect contents. ·         The merge wizard in Visual Studio does not display all valid merge targets for a given source path/branch. ·         During merging, merge candidates are shown for changes that were already merged prior to the upgrade. If you have not yet upgraded to TFS 2010, the hotfix is now available and is highly recommended to be applied before configuring your team project collections. Because this hotfix applies to the upgrade of version control content, it must be applied after TFS 2010 setup is complete, but before configuration is started.  At the end of the setup experience, the Success screen is shown indicating the completion of the installation.  Normally, users will continue on to the configuration part, but in this case, the user need to cancel the configuration part by un-checking the “Launch Team Foundation Server Configuration Tool” box, which will enable the Cancel button. After exiting setup, the hotfix executable can be run to update the upgrade steps. Once the hotfix is installed, the TFS Configuration Wizard will need to be re-launched from the Start Menu to complete the upgrade process.    The hotfix has been published on MSDN Code Gallery – you can find it here: http://code.msdn.microsoft.com/KB2135068   If you have upgraded to TFS2010 and facing any of the above issues, then checkout this KB for Resolution: http://support.microsoft.com/kb/2193796/en-us

• Websockets through Stunnel is giving random bytes.

  - by user16682

  I have several servers set up for a web application that I am developing. One is a load balancing server, and I'm running a php WebSockets server on this balancer. The website that I am developing on uses ssl, so I have my WebSockets running through a wss uri connecting directly to the balancer, where I have set up stunnel4 to decrypt all traffic at a certain port and re-rout it to my php WebSockets server. This works fine when it comes down to connecting to my server. That's not the problem. The problem occurs when I try to send data to the server. Occasionally when I try this, stunnel does not appear to be decrypting the data properly. I get garbage characters in my termanal running the server: what appear to be completely random bytes. This can sometimes go on for several consecutive messages that I send before abruptly working again. It is very erratic and unpredictable. Sometimes I refresh the page, and all the messages work perfectly. Sometimes the WebSocket connects and I have to wait 5-10 seconds before any messages I send are interpreted properly by the server. Other times I can't send any messages at all, because they all end up as garbage. I believe this is a stunnel problem, but I am not certain. Does anybody have any experience with this? I would like a more predictable server if I can get it. Some more information: This occurs extensively in Chrome, not quite as much in FireFox, and never in Safari. The php server I am using is phpws http://code.google.com/p/phpws/ -- On the WebSocket connection, this server would sometimes detect that the header was only 1 byte in size, the first byte of the WebSockets header. I had to modify the server to flush the buffer ever time this occurred so that it would reliably connect.

• Versioning millions of files with distributed SCM

  - by C. Lawrence Wenham

  I'm looking into the feasibility of using off-the-shelf distributed SCMs such as Git or Mercurial to manage millions of XML files. Each file would be a commercial transaction, such as a purchase order, that would be updated perhaps 10 times during the lifecycle of the transaction until it is "done" and changes no more. And by "manage", I mean that the SCM would be used to not just version the files, but also to replicate them to other machines for redundancy and transfer of IP. Lets suppose, for the sake of example, that a goal is to provide good performance if it was handling the volume of orders that Amazon.com claimed to have at its peak in December 2010: about 150,000 orders per minute. We're expecting the system to be distributed over many servers in order to get reasonable performance. We're also planning to use solid-state drives exclusively. There is a reason why we don't want to use an RDBMS for primary storage, but it's a bit beyond the scope of this question. Does anyone have first-hand experience with the performance of distributed SCMs under such a load, and what strategies were used? Open-source preferred, since the final product is to be FOSS, too.

• Database Schema Usage

  - by CrazyHorse

  I have a question regarding the appropriate use of SQL Server database schemas and was hoping that some database gurus might be able to offer some guidance around best practice. Just to give a bit of background, my team has recently shrunk to 2 people and we have just been merged with another 6 person team. My team had set up a SQL Server environment running off a desktop backing up to another desktop (and nightly to the network), whilst the new team has a formal SQL Server environment, running on a dedicated server, with backups and maintenance all handled by a dedicated team. So far it's good news for my team. Now to the query. My team designed all our tables to belong to a 3-letter schema name (e.g. User = USR, General = GEN, Account = ACC) which broadly speaking relate to specific applications, although there is a lot of overlap. My new team has come from an Access background and have implemented their tables within dbo with a 3-letter perfix followed by "_tbl" so the examples above would be dbo.USR_tblTableName, dbo.GEN_tblTableName and dbo.ACC_tblTableName. Further to this, neither my old team nor my new team has gone live with their SQL Servers yet (we're both coincidentally migrating away from Access environments) and the new team have said they're willing to consider adopting our approach if we can explain how this would be beneficial. We are not anticipating handling table updates at schema level, as we will be using application-level logins. Also, with regards to the unwieldiness of the 7-character prefix, I'm not overly concerned myself as we're using LINQ almost exclusively so the tables can simply be renamed in the DMBL (although I know that presents some challenges when we update the DBML). So therefore, given that both teams need to be aligned with one another, can anyone offer any convincing arguments either way?

• Development environment to manage multiple Oracle databases

  - by jkohlhepp

  I am in an enterprise environment where we have applications that need to run against multiple Oracle databases. Developers may need to manage multiple vintages of these databases to support different test data or diagnose bugs against different versions of the code. Right now, we have a limited set of test environments set up on "real" Oracle servers within the data center. We juggle these among development and QA groups and there is a lot of conflicts and inefficiencies that arise because of it. I am taking a look at Oracle Express Edition which would allow me to spin up a local Oracle database. This is similar to the workflow I most often see with SQL Server. Devs work on their location machine until they are ready to integration and then they push their DB changes to integration / QA environments. However, from what I read it seems that Oracle XE only supports one database instance at a time. So if I have an application that utilizes two different databases, I can't have both of them running on my local machine. Is that correct? Does Oracle Standard or Personal editions get around this limitation? If I had one of those installed locally, how difficult would it be to get multiple databases working on the same development machine? How do dev shops handle developing against Oracle where they need to be using several different Oracle instances for their applications?

• Leadership does not see value in standard process for machine configuration and new developer orientation

  - by opensourcechris

  About 3 months ago our lead web developer and designer(same person) left the company, greener pastures was the reason for leaving. Good for them I say. My problem is that his department was completely undocumented. Things have been tough since the lead left, there is a lot of knowledge both theoretical knowledge we use to quote new projects and technical/implementation knowledge of our existing products that we have lost as a result of his departure. My normal role is as a product manager (for our products themselves) and as a business analyst for some of our project based consulting work. I've taught myself to code over the past year and in an effort to continue moving forward I've taken on the task of setting my laptop up as a development machine with hopes of implementing some of the easier feature requests and fixing some of the no brainer bugs that get submitted into our ticketing system. But, no one knows how to take a fresh Windows machine and configure it to work seamlessly with our production apps. I have requested my boss, who is still in contact with the developer who left, ask them to document and create a process to onboard a new developer, software installation, required packages, process to deploy to the productions application servers, etc. None of this exists, and I'm spinning my wheels trying to get my computer working as a functional development machine. But she does not seem to understand the need for such a process to exist. Apparently the new developer who replaced the one who left has been using a machine that was pre-configured for our environment, so even the new developer could not set up a new machine if we added another developer. My question is two part: Am I wrong in assuming a process to on-board and configure a new computer to be part of our development eco-system should exist? Am I being a whinny baby and should I figure the process out and create a document on my own?

• Strategy for managing lots of pictures for a website

  - by Nate

  I'm starting a new website that will (hopefully) have a lot of user generated pictures. I'm trying to figure out the best way to store and serve these pictures. The CMS I'm using (umbraco) has a media library that puts a folder on the server for each image. Inside of there you can have different sizes of that same image. That folder has an ID on it and the database has additional information for that image along with the ID of the folder. This works great for small sites, but what if the pictures get up to 10,000, 100,000 or 1,000,000? It seems like the lookup on the directory would take a long time to find the correct folder. I'm on windows 2008 if that makes a difference. I'm not so worried about load. I can load balance my server pretty easily and replicate the images across the servers. The nature of the site won't have a lot of users on it either, but it could have a lot of pics. Thanks. -Nate EDIT After some thought I think I'm going to create a directory for each user under a root image folder then have user's pictures under that. I would be pretty stoked if I had even 5,000 users, so that shouldn't be too bad of a linear lookup. If it does get slow I will break it down into folders like /media/a/adam/image123.png. If it ever gets really big I will expand the above method to build a bigger tree. That would take a LOT of content though.

• .Net search engine architecture and technology choice

  - by shrivb

  I am in the process of designing a search engine for an asp.net site. The site currently uses Microsoft Indexing Server to index and search content which range from simple text files to MS documents to PDFs. MIS is also used to crawl File servers. MIS in tandem with Index Server Companion crawls for content from external sites. I intend to replace MIS with the indexer/crawler I am trying to build. Since my platform is completely on the Microsoft stack, I cant afford to have a Java application server. Thus, Solr, and effectively, SolrNet is ruled out. With this being the context, I have couple of questions. 1.Technology choice I had done my initial investigation and looked at Lucene.Net. There seemed to be 2 issues in using Lucene.Net. First being, it cant crawl external content. There doesn't seem to be a direct port of Nutch in .Net. Second, since it is just an indexer, it cant parse various document types. The parsing is left to the developer. So, what would be best technology choice on the .Net platform to achieve indexing & crawling? Are there any .Net open source libraries available for document parsing? 2.Architectural pattern Is there any general architectural pattern or best practice that needs to be followed in designing such a search engine? Thanks in advance.

• We Found 100 Manufacturing Heros That Focus on Innovation!

  - by Stephen Slade

  There’s a good piece written by Ann Grackin of ChainLink Research on the Manufacturing Leadership 100 Awards program held recently in Palm Beach Fl, Apr 30-May 3, 2012.  This article (link below) highlights the summary of the Summit with specific focus on manufacturing innovation.  There were several informative keynotes and sessions from industrial leaders who are leveraging the latest tools and technologies to make better decisions. Ann writes that she was a panelist with Cindy Reese, SVP, Worldwide Operations, Oracle; and Steven Tungate, VP/GM, Supply Chain & Innovation, Toshiba America Business Solutions about Factories and Supply Networks of the Future. Ann writes “So what are these manufacturers doing? Significant rationalization of the supply base (Toshiba, especially, has this issue since they have a long history of many acquisitions), streamlining production to increase productivity, and looking for lower-cost countries for manufacturing….  No doubt firms have global customer bases, so they need to be present in these markets. However, a low-cost-country manufacturing source does introduce more risk in the supply chain. And that was discussed. Quality, security, and intellectual property protection were the critical global manufacturing issues also discussed. “Cindy (Reese) told a fascinating story about Oracle’s acquisition of Sun and the supply chain that was subsequently created. Here was one of the key points: Although Oracle sells on a global basis, they now do their own factory-installed software. This keeps potential ‘factory-installed malware’ from getting into the servers at contract manufacturers, and prevents pirated software. In this way, Oracle ensures that they deliver the quality and security people expect”.

• Free Team Foundation Service a Boon for Play Projects

  - by Ken Cox [MVP]

  My ‘jump in and sink or swim’ learning style leads me to create dozens of unbillable ‘play’ projects in Visual Studio 2012.  For example, I’m currently learning to customize the powerful auction/fixed price/classifieds software called AuctionWorx Enterprise.  I make stupid mistakes as I grasp a new API and configure projects. It’s frustrating to go down a rat hole and discover the VS IDE’s Undo doesn’t reach back to a working build from the previous weekend. Enter Visual Studio’s Free Team Foundation Service.  Put your play projects into the free source control and check in (or shelve) a snapshot before embarking on something risky. (I already use Discount ASP.NET’s Team Foundation Server hosting for client projects so there’s zero TFS/VS learning curve for me and first class GUI support.) TFS is free right now for teams of five or fewer. I’m not naive enough to expect ‘free’ to last forever. So, it’ll be interesting to see how much Microsoft intends to charge in 2013 for TFS. In the meantime, why not grab some free source code storage? BTW, it’s weird to realize that Microsoft is backing up my junky little playtime code on three physically-distinct servers every day - and taking incremental backups every hour.

• Session state provider and atomic operations

  - by vtortola

  Hi, I've been thinking about this and it is blowing my mind... How does a session state provider properly works internally? I mean, I tried to write a custom session state provider based on Azure Tables or Blobs, but quickly I realized that because there is no way to ensure an atomic operation or establish a lock, race conditions are suitable to happen when several web servers do operation on that shared information. I know that there is a SQL Server Session State Provider (SQLS-SSP) and people is happy with it, so I guess that it's using some kind of transaction isolation level in order to accomplish some degree of concurrent safety, like checking is the data is lock (a simple column), locking it if not and returning the data in an atomic operation, but is that so? what does happen if the data is lock? does it returns an error? block the call for a while? returns it in read-only fashion? Cloud computing paradigms could be somehow new, but webfarms have been here for a while, so as I'm pretty new on it... do you recommend any good lecture about the topic? Thanks.

• Does ssh key need to be named id_rsa?

  - by dustyprogrammer

  I have come across this problem a couple of times when creating build servers with keyed authentication. I was wondering if anyone else has experience this. I have a couple of keys for my current user that may connect to different machines. Let say machine1 and machine2. I have pasted my public key into their respective authorized_keys file. The first one I have named the first key id_rsa and the second key bender. When I try to connect to bender I get the following output with my verbose ssh connection debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: /home/bozo/.ssh/.ssh/identity debug1: Trying private key: /home/bozo/.ssh/.ssh/id_rsa debug1: Trying private key: /home/bozo/.ssh/id_dsa debug1: No more authentication methods to try. Permission denied (publickey). It only offers the id_rsa key, as you can see above. Is this correct? If so why? How do I get it to offer more keys? I know it is a problem I see intermittently, because I at home I have multiple keys without much trouble. I would also appreciate a overview on how the pub and private keys interact with the client and server. I thought I had a pretty decent idea, but apparently I am missing something. Please and thank you.
