• SharePoint 2010, Cloud, and the Constitution

  - by Michael Van Cleave

  The other evening an article on the Red Tap Chronicles caught my eye. The article written by Bob Sullivan titled "The Constitutional Issues of Cloud Computing" was very interesting in regards to the direction most of the technical world is going. We all have been inundated about utilizing cloud computing for reasons of price, availability, or even scalability; but what Bob brings up is a whole separate view of why a business might not want to move toward the cloud for services or applications. The overall point to the article was pretty simple. It all boiled down to the summation that hosting "Things" in the cloud (Email, Documents, etc…) are interpreted differently under the law regarding constitutional search and seizure than say a document or item that is kept in physical form at a business or home. Where if you physically have it stored someone would have to get a warrant to search for it or seize it, but if it is stored off in the cloud and the ISV or provider is subpoenaed for the item then they will usually give access to the information. Obviously this is a big difference in interpretation of the law and the constitution due to technology. So you might ask "Where does this fit in with SharePoint? Well the overall push for this next version of SharePoint is one that gives a business ultimate flexibility to utilize the Cloud. In one example this upcoming version gracefully lends itself to Multi Tenancy so that online or "Cloud" hosting would be possible by Service Providers. Another aspect to the upcoming version is that it has updated its ability to store content outside of the database and in a cheaper commoditized storage facility. This is called Remote Blob Storage (or RBS) which is the next evolution of External Blob Storage (or EBS). With this new functionality that business might look forward to it is extremely important for them to understand that they might be opening themselves up to laws that do not need a warrant to search or seize their information that is stored in the cloud. It will be interesting to see how this all plays out in the next few months. Usually the laws change slowly in comparison to technology so it might be a while until we see if it is actually constitutional to treat someone's content on the cloud differently as it would be in their possession, however until there is some type of parity that happens or more concrete laws regarding the differences be very careful about what you put in the cloud.

• Social Technology and the Potential for Organic Business Networks

  - by Michael Snow

  Guest Blog Post by:  Michael Fauscette, IDCThere has been a lot of discussion around the topic of social business, or social enterprise, over the last few years. The concept of applying emerging technologies from the social Web, combined with changes in processes and culture, has the potential to provide benefits across the enterprise over a wide range of operations impacting employees, customers, partners and suppliers. Companies are using social tools to build out enterprise social networks that provide, among other things, a people-centric collaborative and knowledge sharing work environment which over time can breakdown organizational silos. On the outside of the business, social technology is adding new ways to support customers, market to prospects and customers, and even support the sales process. We’re also seeing new ways of connecting partners to the business that increases collaboration and innovation. All of the new "connectivity" is, I think, leading businesses to a business model built around the concept of the network or ecosystem instead of the old "stand-by-yourself" approach. So, if you think about businesses as networks in the context of all of the other technical and cultural change factors that we're seeing in the new information economy, you can start to see that there’s a lot of potential for co-innovation and collaboration that was very difficult to arrange before. This networked business model, or what I've started to call “organic business networks,” is the business model of the information economy.The word “organic” could be confusing, but when I use it in this context, I’m thinking it has similar traits to organic computing. Organic computing is a computing system that is self-optimizing, self-healing, self-configuring, and self-protecting. More broadly, organic models are generally patterns and methods found in living systems used as a metaphor for non-living systems.Applying an organic model, organic business networks are networks that represent the interconnectedness of the emerging information business environment. Organic business networks connect people, data/information, content, and IT systems in a flexible, self-optimizing, self-healing, self-configuring, and self-protecting system. People are the primary nodes of the network, but the other nodes — data, content, and applications/systems — are no less important.A business built around the organic business network business model would incorporate the characteristics of a social business, but go beyond the basics—i.e., use social business as the operational paradigm, but also use organic business networks as the mode of operating the business. The two concepts complement each other: social business is the “what,” and the organic business network is the “how.”An organic business network lets the business work go outside of traditional organizational boundaries and become the continuously adapting implementation of an optimized business strategy. Value creation can move to the optimal point in the network, depending on strategic influencers such as the economy, market dynamics, customer behavior, prospect behavior, partner behavior and needs, supply-chain dynamics, predictive business outcomes, etc.An organic business network driven company is the antithesis of a hierarchical, rigid, reactive, process-constrained, and siloed organization. Instead, the business can adapt to changing conditions, leverage assets effectively, and thrive in a hyper-connected, global competitive, information-driven environment.To hear more on this topic – I’ll be presenting in the next webcast of the Oracle Social Business Thought Leader Webcast Series - “Organic Business Networks: Doing Business in a Hyper-Connected World” this coming Thursday, June 21, 2012, 10:00 AM PDT – Register here

• Getting mysql row that doesn't conflict with another row

  - by user939951

  I have two tables that link together through an id one is "submit_moderate" and one is "submit_post" The "submit_moderate" table looks like this id moderated_by post 1 James 60 2 Alice 32 3 Tim 18 4 Michael 60 Im using a simple query to get data from the "submit_post" table according to the "submit_moderate" table. $get_posts = mysql_query("SELECT * FROM submit_moderate WHERE moderated_by!='$user'"); $user is the person who is signed in. Now my problem is when I run this query, with the user 'Michael' it will retrieve this 1 James 60 2 Alice 32 3 Tim 18 Now technically this is correct however I don't want to retrieve the first row because 60 is associated with Michael as well as James. Basically I don't want to retrieve that value '60'. I know why this is happening however I can't figure out how to do this. I appreciate any hints or advice I can get.

• Map Caps-Lock to Control in Windows 8.1

  - by Eric Huang

  Before the Windows 8.1 update, I was able to map Caps-Lock to Controls through the type of registry tweak in this post: Remapping a keyboard key in windows 8.1 However, after updating to 8.1, my tweak no longer works. What I had done was Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout] "Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,1d,00,3a,00,00,00,00,00 Windows 8.1 may have changed how it interprets the keyboard layout registry, I'm guessing. I'm an avid emacs user, so this problem is a life-or-death scenario for me.

• About Load average in htop, how to decide if it's still doing ok?

  - by Joe Huang

  I use 'htop' to monitor my web server. It's recently quite loaded and the Load average is showing something like this: Load average: 3.10 2.56 1.63 I searched the web about these numbers and I found an article about it: http://blog.scoutapp.com/articles/2009/07/31/understanding-load-averages In the article, it says if I have 2 CPUs, 2.0 means 100% CPU utilization. And my VPS has two CPUs, so what does 3.1 mean? How could it exceed 100% CPU utilization? And from these numbers, does it mean I should be wary about the loading now? But the performance seems totally fine, and this is a managed VPS, the hosting company has not notified me any warning about it. During day time, Load average always show these high numbers... here is another snapshot while writing. Load average: 3.03 2.77 1.97 Load average: 0.41 1.29 1.60 <---- 5 more minutes later So I am wondering how much room left for this site to grow in current configurations? What kind of proactive actions I should take in advance? I don't want to wait until the server bursts. Thanks.

• What do you use to loadbalance IPv6 services?

  - by Michael Renner

  Hi, the current Linux software environment for IPv6 load balancing looks a bit grim. IPVS has rudimentary support for IPv6 but it's far from complete. NAT for IPv6 seems to be a no-go. Are there any other projects which aim for this goal? Does the IPv6 support in other OS look better? Are there any commercial products which have been successfully used in production environments with non-trivial load patterns? Or is it just that the time for IPv6 hasn't come... yet? ;) best regards, Michael

• bash disable line wrap without truncation

  - by Eric Huang

  I am using a template heavy library in c++ and need to understand the template errors. Reading line wrapped template errors is a serious pain. Is there a way to disable line wrapping in bash without also truncating the output. Additionally, is there a way to do horizontal scrolling on the output. I have seen this answer, how to make bash not to wrap output?, but the output is truncated. The solution doesn't have to be bash targeted, if there is method for this using another shell, tmux, piping make output to another program, compiling from within vim, etc, I'll use it. (Except for copy-pasting into gedit)

• Windows 7 Locking up Randomly

  - by Michael Moore

  I've got a Windows 7 machine that is locking up randomly. It can be in the first thirty seconds, or it can be hours later. There is nothing specific I can find that is running when it happens. When it locks, the screen doesn't change, but nothing moves. The waiting icon stops, the mouse stops, keyboard doesn't work, etc. I've even tried the crash on ctrl-scrl registry hack, and it won't even dump the kernel. I've run hardware diagnostics on the RAM and it doesn't find any problems. I would think it is a hardware issue, but on this exact same machine, I can run 64 Bit Ubuntu and it has zero problems. I've even tried reinstalling Windows7 from scratch, and it still happens. Anyone have any ideas? Any good diagnostic tools to recommend? Thanks! Michael

• Secure copy in Linux

  - by Michael

  Hi all, I wanna simpy exchange 3 directories to a collegue's home directory (I dont have write access to that one) from my home directory, probably using secure copy if possible. I am not good with Linux command line, so I am not sure how to do that and I would very much appreciate it if somebody could help me a bit out with this. I guess it should look something like that scp -r /home/user1/directoy1 /home/user2/directoy1 scp -r /home/user1/directoy2 /home/user2/directoy2 scp -r /home/user1/directoy3 /home/user2/directoy3 Do I need to specify the login name of my collegue so that the files can be copied when he enters his password?

Thanks in advance... Michael

• Virtual hosting in Varnish with individual vcl files for configuration

  - by Michael Sørensen

  I wish to use varnish to put in front of an apache and a tomcat on the same server. Depending on the ip requested, it goes to a different backend. This works. Now for most of the sites the default varnish logic will work just fine. However for some specific sites I wish to use custom VCL code. I can test for host name and include config files for the specific domains, but this only works inside the individual methods recv etc. Is there a way to include a complete set of instructions, in one file, per domain, without having to manage separate files for subdomain_recv, subdomain_fetch etc? And preferably without running seperate instances of varnish. When I try to include a file on the "root level" of default.vcl, I get a compilation error. Best regards, Michael

• How to setup server to accept pem(private RSA key) login w/o password like EC2?

  - by Chandler.Huang

  I am manage a group of VM and I need to setup all vm create a ssh tunnel to a specific host A. One way to do this is append public key of each VM to host's authorized_keys, but I guess I have to do the append each time i create a VM. So I am trying to config host A to accept pem or private key login without passowrd, just like EC2, client can use "ssh -i PEM" to login host A. But I have tried in vain for hours. I create a rsa public/private key and let VM use the private key to login, no matter what I do, host a still ask for password. Is there anything I missed ? Thanks.

• Does it make a difference to read from a file instead of from MySQL?

  - by Joe Huang

  My web server currently is quite loaded. And I have a PHP file that is accessed very often remotely. The PHP file basically makes a MySQL query and returns a JSON formatted string. I am thinking to use a Cron job to write the necessary data into a file every 15 mins, so the PHP file doesn't make a MySQL query, instead it reads from the file. Does it make a difference? I mean to alleviate the server loading (CPU/MySQL) a bit?

  Hey, I have the eventual goal of determining that a particular database on a particular server with particular credentials is running, but I would settle, at this point, for the ability to check and see if a server is actually up on the network.

• jQuery jFlow plugin. How can I have more than one on a single page?

  - by Michael

  Hi, I'm using a very lovely and simple plugin called jFlow that gives me a basic content slider etc. However, I can see no documentation or help on how to get two (or more) on one page at the same time working seperately from one another. At the moment, if I set two up, they almost combine as one, despite having a different configuration from one another. Any help would be great, thanks. Michael.

• simple yet secure encrypt / decrypt asp to asp.net

  - by Michael

  First post here. I have a asp/vb6 web app that logs in a user I want to encrypt the users identity field and pass(querystring) it to a asp.net app and then decrypt it to do a db lookup. I've google'd it of course and found rot13, not secure enough. I've also found some hits on MD5 / RC4 but did not find any good examples of encrypt / decrypt. Thanks, Michael

  - by Michael Ruepp

  Hy everybody, I have two targets in one Project in Xcode. One is a foundation tool which i need in the resources Bin of the other Target, which is a Bundle App. I am not able to add the Target one into the Copy Bundle Resources Build Phase of the Bundle App. Do I need to use a Copy Files Build phase and put the File out of the build/Release Folder into it?
