• Turn O&M Operations into Optimized Projects with Oracle Primavera

  - by mark.kromer

  Oracle enterprise project portfolio management with Primavera is much more than optimizing project performance and eliminating project failure on new projects, capital programs, etc. A very common use case that we see is small-scale frequent and recurring projects based on on-going operations and maintenance. As opposed to assigning resources to various activities when you are building a new network infrastructure, for example, Oracle has teamed-up the Primavera and eBusiness Suite teams to provide direct integration for work orders from Oracle's Enterprise Asset Management (eAM) system to populate into Primavera P6 project schedules. So now that your network infrastructure build-out project is complete, planners and operations managers can use the world-class what-if and scheduling capabilities in Primavera tools to assign work orders, maximize resource utilization and to reuse templates for typical O&M operations in Primavera and share that back to the operations teams using eAM for maintenance. Also, large-scale maintenance operations related to large assets in the asset lifecycle will include phase-outs, shutdowns and turn-arounds which are classic maintenance projects, as opposed to building something new, that Oracle Primavera with Oracle e-Business Suite provides full coverage to optimize your ALM processes in your business. Read more about these new capabilities from Oracle in the ERP space from the Oracle eAM data sheet.

• More Tables or More Databases?

  - by BuckWoody

  I got an e-mail from someone that has an interesting situation. He has 15,000 customers, and he asks if he should have a database for their data per customer. Without a LOT more data it’s impossible to say, of course, but there are some general concepts to keep in mind. Whenever you’re segmenting data, it’s all about boundary choices. You have not only boundaries around how big the data will get, but things like how many objects (tables, stored procedures and so on) that will be involved, if there are any cross-sections of data (do they share location or product information) and – very important – what are the security requirements? From the answer to these types of questions, you now have the choice of making multiple tables in a single database, or using multiple databases. A database carries some overhead – it needs a certain amount of memory for locking and so on. But it has a very clean boundary – everything from objects to security can be kept apart. Having multiple users in the same database is possible as well, using things like a Schema. But keeping 15,000 schemas can be challenging as well. My recommendation in complex situations like this is similar to a post on decisions that I did earlier – I lay out the choices on a spreadsheet in rows, and then my requirements at the top in the columns. I  give each choice a number based on how well it meets each requirement. At the end, the highest number wins. And many times it’s a mix – perhaps this person could segment customers into larger regions or districts or products, in a database. Within that database might be multiple schemas for the customers. Of course, he needs to query across all customers, that becomes another requirement. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Building an intranet

  - by WernerCD

  I'm researching for a project I'm going to be doing at work on the side... I work for a small hospital and we recently upgraded all the browsers inside our intranet to IE8 (Goodbye 6 :). We have a small, obsolete intranet built by someone who isn't a web designer... functional enough, but annoying to maintain and really sparse. What I'm wanting to do... is use a good framework. I'm looking for suggestions... I'm looking for something Windows IIS based. I'd love windows authentication - with the ability to delegate sub-sections of the website to managers. Right now it's my job to add/update/delete anything from the site... I'd like something not complicated that can be delegated to non-technical people. Like... the Cafeteria Manager should be able to update the menu without putting a ticket into me. She'd log into her computer, open the intranet (which would use her windows log-on to identify her) and have elevated privileges to edit her section of the intranet. If I have to "extend" a good framework to get Windows Authentication, I'll do it... but I'd prefer it to be baked in. What are some good frameworks, tools and places to start? While this isn't a "Huge" project... it's going to be bigger than the basic stuff I've done before and I'd like a good place to start.

• MS Marketing Strategy

  - by Aaron Kowall

  I found this week’s Windows Phone 8 event interesting.  Not just because it looks like some fantastic new features in the new OS but because of the wait for release.  If I were a Nokia shareholder (which I am not) I’d be very unhappy with MS announcing that Windows Phone 8 will NOT work with current hardware.  So, there are some very nice Lumia devices that are now end-of-life that have arrived relatively recently at carriers and retailers. I understand that MS needs to demonstrate progress against iOS and Android and that there is some Windows 8 tie-in that they are trying to capitalize (and MS IS still all about Windows).  However, it’s a bit of a kick to partners that have invested in the platform with pretty decent devices (Samsung, HTC and of course Nokia). Personally, I’m still using a Samsung Foucs.  I was seriously considering upgrading to a Lumia 900 (we just got Lync mobile available) but will now wait it out until new devices arrive with Windows 8.  If MS had waited to announce, I would happily have upgraded to the Lumia and when I found out it couldn’t be upgraded then that would be a gamble I took and lost and I’d live with it.  Now, however, I can see the future and know that waiting is the better option for me so that is 1 sale Nokia will miss out on.  Based on some chats I’ve seen on mobile forums I’m certainly far from the only one. I’m sure glad I’m not in charge of marketing at MS.  There are tough decisions to be made there and I’m pretty sure you piss somebody off regardless. Technorati Tags: WP8,Lumia,Nokia,Samsung

• How much a programmer should read in order to keep himself updated? [closed]

  - by anything

  There are lots of technical books available. Below are few links which lists some good books If you could only have one programming related book on your bookshelf what would it be and why? What non-programming books should a programmer read to help develop programming/thinking skills? Best books on the theory and practice of software architecture? http://stackoverflow.com/questions/1711/what-is-the-single-most-influential-book-every-programmer-should-read ... and the list can go on and on and on. It will be really difficult to read all of the above mentioned books. I am not sure if its even possible for anyone to do that. Even if you filter it based on one's area of interest or work, list is still very large. .. and the technology keeps on changing (even more books :-( ) So, my question is how much a programmer should read lets say per year? How much hours one should put in such activities to keep oneself up to date? How do we find out the time required? PS: Average programmer reads less than one book per year (Code complete). What about the good programmers?

• Mutt: apply command to all tagged messages

  - by mrucci

  From the mutt manual: Once you have tagged the desired messages, you can use the tag-prefix operator, which is the ; (semicolon) key by default. When the tag-prefix operator is used, the next operation will be applied to all tagged messages if that operation can be used in that manner. But it seems that I can only execute commands that are already bound to a specific keyboard shortcut. For example I can use ;d to delete all selected messages. What if I want to apply an "unbound" command (such as purge-message)? I have also tried using something based on :exec tag-prefix or :push tag-prefix without success.

• SharePoint 2013 Licensing Simplified

  - by Sahil Malik

  SharePoint 2010 Training: more information Before I begin, let me preface this by saying, I don't work for Microsoft, I don't sell SharePoint, this is merely my understanding of the SharePoint 2013 licensing model. As always, before making any money decisions based on the below, talk to your Microsoft rep. The below is just my understanding, you are responsible for any decision you may take. With that aside, here is how I understand SharePoint 2013 licensing. Note that everything below is for on-prem SharePoint only. Also it goes without saying that you need to purchase windows server and SQL server licenses etc. on top of what you read below. The Basics. You need to buy two things - the SharePoint server, and CALs. SharePoint server comes in SharePoint foundation, standard and enterprise. CALs can be either enterprise or standard, and they can be bought as CALs for SharePoint or a CAL suite which includes exchange and lync. CALs can also be purchased and user CAL or device CAL.

• Taskbar Disappears Over Remote Desktop Connection When Outside Local Network

  - by CMikeB1

  I've got a machine on my home network running Windows Server 2012 (Based on Win8) and rather than attach a monitor I remote desktop in and it works fine on my local network. The problem is, when I try to access it from outside my local network the taskbar disappears completely. When I minimize an application rather than minimize to the taskbar it simply closes the window as small as it can as if the taskbar never existed (see photos at ). I've messed with the connection properties (show/hide desktop background, etc.) with no luck. I've used the following methods to remote in and they all are fine when on the local network and taskbar-less from outside: Remote Desktop Connection on Mac Remote Desktop Connection on Windows Jump Desktop on iOS using RDP To access the computer from outside my local network I'm using a Linksys router and mapping to the server IP, port 3389.

• How to make TortoiseHg pull certain branch only?

  - by mark

  I have cloned the default branch of a big repository and now I wish to pull from the server using the TortoiseHg client. However, TortoiseHg proposes to pull from all the branches. Is it possible to instruct it to pull from the current branch only? So far I have seen suggestions to: Setup a hook on the client side to reject pulls from unwanted branches Check incoming revisions in TortoiseHg and only pull the ones belonging to the current branch Use the Mercurial ACL extension to deny access to all the branches, but the current one. I dislike all of these solutions, since all of them are client based. In all of them TortoiseHg actually pulls all of the branches (even in the second, where the pulled revisions are arranged into a bundle presented in the incoming revisions view) Is there an hg pull -b BRANCH equivalent in TortoiseHg? Thanks. EDIT I know how to do all of this using the Mercurial command line client - hg.exe. This question is specifically about the TortoiseHg GUI client.

• Directing Multiple ccTLD's to 1 gTLD with a country specific subdirectory?

  - by Pascal Van Opzeeland

  We have multiple ccTLDomains and are thinking about how to best combine these into one. We want to do this to focus our link building efforts. We are running a website through which we offer a software-as-a-service. Therefore we could potentially sell to any country in the world. However, Germany is our most important market. We currently have a .com, .de, .nl. and .pl domain. All these domains have a high amount of unique content pages. What we are planning is to change everything to .com with language-based subdirectories, so .com/en/, .com/de/, etc. I have two questions concerning this issue: 1) How much of an advantage does a ccTLD have over a gTLD with country specific subdirectories in search rankings? So let’s say .de versus .com/de/? 2) How could we best redirect the visitors of our old ccTLD’s to our gTLD’s subdirectories? We would like to loose as few search engine rankings as possible. Thank you for your help.

• Outlook 2010 search stopped working with Exchange 2007

  - by Steve Hiner

  The quick search feature in Outlook 2010 used to work fine. We switched the computers over from a workgroup so that they are on the domain with our new server. We then copied all the email from the old PST file into the new Exchange based folders. Since we did that 3 of the 4 computers can't search email using Outlook's awesome search boxes. One of them works perfectly fine. Any idea what might have happened? There are only 5 users on the network and it's a pretty burly server for such a small network, I can't imagine the server is still indexing their mail. Is the quick search something that has to be turned on or might it be related to the permissions change from a non-domain user to a standard domain user?

• Unique string values in range

  - by Dean Smith

  I have some spreadsheets where there are large number of cells that have essentially been used for free text. There is a finite set of values for this free text and most, if not all repeat. eg. A B C D 1 Monkey Gorilla Cat Dog 2 Dog Cat Gorilla Gorilla 3 Dog Dog Dog Cat There are probably 50 or so different cell values spread over multiple sheets and hundreds of rows and columns. I need to analyse this data and count occurancies, which is not a problem other than getting a list of unique values to start with and this has been driving me up the wall. What is the best way to produce this list. So from the above we would have Monkey Dog Cat Gorilla In order of preferred solutions, as this will need to be done monthly.

• Choosing the correct network protocol for my type of game (its Wc3 Warlock style)

  - by Moritz

  I need to code a little game for a school project. The type of the game is like the Warcraft 3 map "Warlock", if anyone doesnt know it, here is a short description: up to ten players spawn into an arena filled with lava, the goal of each player is to push the other players into the lava with spells (basically variations of missiles, aoe nukes, moba spells etc) http://www.youtube.com/watch?v=c3PoO-gcJik&feature=related we need to provide multiplayer-support over the internet, for that reason I am looking for the best network protocol for this type of game (udp, tcp, lock step, client-server...) what the requirements are: - same/stable simulation on all clients - up to ten players - up to ~100 missiles on the field - very low latency since its reaction based (i dont know the method wc3 used, but it was playable with the old servers) what would be nice (if even possible, since the traffic might be too big): - support for soft bodies over the network (with bullet physics), but this is no real requirement I read several articles about the lock step method used for RTS games, this seems to be great, but does it fit for real-time action games too (ping-related)? If anyone has run into the same problems/questions like me, I would be very happy about any help

• How to limit access to Exchange 2003 Mobile Actviesync server by user?

  - by micilin

  So I was asked to set up an Exchange Activesync mobile gateway. That's done. It's a separat eExchange 2003 front-end server configured for SSL, and I've put an off-domain ISA server in front of it. Now I'm being asked to limit which users can connect to it. By default an Exchange front-end server allows any user who has a mail account to connect to the front -end server. So I'm looking at the permissions on the various IIS sites/apps on the server, but I know that it's easy to break Exchange Front-end server perms. So I've got the following in IIS: Exadmin Exchange EchWeb Microsoft-SErver-ActiveSync MobileAdmin OMA And a couple of others that I dont think are relevant. Can I change the permissions on one of these to restrict who can connect to Activesync? As a bonus: Can I do it in a way that does not affect ordinary browser based Exchange Access? Thanks in Advance!!

• What's a good tool for collecting statistics on filesystem usage?

  - by Kamil Kisiel

  We have a number of filesystems for our computational cluster, with a lot of users that store a lot of really large files. We'd like to monitor the filesystem and help optimize their usage of it, as well as plan for expansion. In order to this, we need some way to monitor how these filesystems are used. Essentially I'd like to know all sorts of statistics about the files: Age Frequency of access Last accessed times Types Sizes Ideally this information would be available in aggregate form for any directory so that we could monitor it based on project or user. Short of writing something up myself in Python, I haven't been able to find any tools capable of performing these duties. Any recommendations?

• 64 bit Windows 7 + 32 bit windows XP dual boot?

  - by Mick

  I have purchased an i7 based PC pre-installed with 64 bit windows 7 (home premium). Unfortunately some third party 32 bit software that I need to use is not working properly (see stackoverflow.com for details). I am now torn between the plan of installing windows XP 32 bit or making it dual boot. Which option do you think will give me the least problems? And if the answer is dual boot, then can you point me to a good guide for how to do it, preferably a guide specifically for my two OS's created in this order (i.e. 7x64 first). EDIT: the performance of my 32bit programs is critical so am concerned about any kind of 32bit XP "emulation".

• Nagios and rrd on a old server

  - by Pier

  I have an old server (P4 based) on which nagios (and all the other tools to monitor) is running. In the last few weeks we are seeing a strange behavior. In the /var/spool/pnp4nagios (where temporary files are stored before getting processed by pnp4nagios daemon) we have many files like perfdata.1274949941-PID-18839 and we get an error in npcd.log: [05-27-2010 11:17:46] NPCD: ThreadCounter 0/15 File is perfdata.1274951306-PID-27849 [05-27-2010 11:17:46] NPCD: File 'perfdata.1274951306-PID-27849' is an already in process PNP file. Leaving it untouched. Sometimes some graph are not drawn. The server is pretty loaded (around 5-6 normally) and i suspect that npcd goes in timeout and leave those files behind. What could I do (apart from change the server)? Few infos about the system: centos 5.5 nagios 3.2.1 pnp4nagios 0.6 (from sources) Thanks

• Multitenancy in SQL Azure

  - by cibrax

  If you are building a SaaS application in Windows Azure that relies on SQL Azure, it’s probably that you will need to support multiple tenants at database level. This is short overview of the different approaches you can use for support that scenario, A different database per tenant A new database is created and assigned when a tenant is provisioned. Pros Complete isolation between tenants. All the data for a tenant lives in a database only he can access. Cons It’s not cost effective. SQL Azure databases are not cheap, and the minimum size for a database is 1GB.  You might be paying for storage that you don’t really use. A different connection pool is required per database. Updates must be replicated across all the databases You need multiple backup strategies across all the databases Multiple schemas in a database shared by all the tenants A single database is shared among all the tenants, but every tenant is assigned to a different schema and database user. Pros You only pay for a single database. Data is isolated at database level. If the credentials for one tenant is compromised, the rest of the data for the other tenants is not. Cons You need to replicate all the database objects in every schema, so the number of objects can increase indefinitely. Updates must be replicated across all the schemas. The connection pool for the database must maintain a different connection per tenant (or set of credentials) A different user is required per tenant, which is stored at server level. You have to backup that user independently. Centralizing the database access with store procedures in a database shared by all the tenants A single database is shared among all the tenants, but nobody can read the data directly from the tables. All the data operations are performed through store procedures that centralize the access to the tenant data. The store procedures contain some logic to map the database user to an specific tenant. Pros You only pay for a single database. You only have a set of objects to maintain and backup. Cons There is no real isolation. All the data for the different tenants is shared in the same tables. You can not use traditional ORM like EF code first for consuming the data. A different user is required per tenant, which is stored at server level. You have to backup that user independently. SQL Federations A single database is shared among all the tenants, but a different federation is used per tenant. A federation in few words, it’s a mechanism for horizontal scaling in SQL Azure, which basically uses the idea of logical partitions to distribute data based on certain criteria. Pros You only have a single database with multiple federations. You can use filtering in the connections to pick the right federation, so any ORM could be used to consume the data. Cons There is no real isolation at that database level. The isolation is enforced programmatically with federations.

• Proxying/Tunneling IPSec traffic via netcat or SOCKS?

  - by MattC

  I have a client that is using a SonicWall router as their VPN concentrator. I downloaded the client software and set up the router as a peer. My issue is that my company uses a dual DMZ setup, meaning we have an interior firewall, then a bunch of DMZ servers, then an external firewall, then finally the telco router. In this setup, the interior firewall has no way to communicate with the exterior firewall since they are on two totally separate subnets. The communication occurs through the servers that straddle the networks. In this case, I need some way to forward the ISAKMP/IPSec traffic from my desktop out to the Internet. My usual trick of using netcat on the intermediate proxy server doesn't work here since it's not TCP/UDP traffic as far as I can tell. All of my previous experience with VPN's have been using SSL-based VPN's which are clearly very easily proxy-able. Any help would be appreciated, thanks!

• Working with lots of cubes. Improving performance?

  - by Randomman159

  Edit: To sum the question up, I have a voxel based world (Minecraft style (Thanks Communist Duck)) which is suffering from poor performance. I am not positive on the source but would like any possible advice on how to get rid of it. I am working on a project where a world consists of a large quantity of cubes (I would give you a number, but it is user defined worlds). My test one is around (48 x 32 x 48) blocks. Basically these blocks don't do anything in themselves. They just sit there. They start being used when it comes to player interaction. I need to check what cubes the users mouse interacts with (mouse over, clicking, etc.), and for collision detecting as the player moves. Now I had a massive amount of lag at first, looping through every block. I have managed to decrease that lag, by looping through all the blocks, and finding which blocks are within a particular range of the character, and then only looping through those blocks for the collision detection, etc. However, I am still going at a depressing 2fps. Does anyone have any other ideas on how I could decrease this lag? Btw, I am using XNA (C#) and yes, it is 3d.

• How to configure a static wildcard subdomain with dnsmasq.

  - by Prody

  I have a network behind a NAT with a few machines. The machines are: router - NAT, dnsmasq, forwarding - directly connected to the inet server - which runs ssh, www and some other stuff clients - which do stuff on server I also have mydomain.com. server.mydomain.com is pointing to my connection's IP (single IP), which is the router, which forwards ports to server. Server, has a httpd running, which serves different sites based on vhosts. So I have site1.server.mydomain.com, site2.. The problem is that all the traffic is going thru the router, and when I check logs I always see the router's IP for everything (so it's hard to see who is running the script with the while(1)). I would just ServerAlias site1.server.local, but most of the sites have a root URL saved somewhere on top of which other URLs are built, so I can't do that. The solution for me would be telling dnsmasq somehow to answer to *.mydomain.com with server's IP. Is this possible somehow?

• Choosing a monitoring system for a dynamically scaling environment: Nagios v. Zabbix

  - by wickett

  When operating in the cloud and scaling boxes automatically, there are certain monitoring issues that one experiences. Sometimes we might be monitoring 10 boxes and sometimes 100. The machines will scale up and down based on a demand. Right now, I think the best solution to this is to choose a monitoring solution that will instantiation of targets via calls to an API. But, is this really the best? I like the idea of dynamic discovery, but that is also a problem in the cloud seeing that the targets are not all in the same subnet. What monitoring solutions allow for a scaling environment like this? Zabbix currently has a draft API but I have been unable to fund a similar API for Nagios. Is there a similar API for Nagios? Anyone have any alternate suggestions besides Nagios and Zabbix?

• Prompt for user group when logging into OSX domain

  - by mattdwen

  When a user is a member of more than one group, when logging in to a 10.6 machine, it shows a prompt asking for what group to apply settings for. We're using the groups to mount different shares, e.g. Production and Accounts, based on user membership. Often, a user is a member of more than one group, and needs all the drives available. The Open Directory server is running 10.6 also. Is there a way to skip this prompt and apply settings for all groups. I can foresee that there may be conflicts between group settings, but perhaps a priority can be set too? Or is this totally the wrong way to go about this?

• Cloning from a given point in the snapshot tree

  - by Fat Bloke

  Although we have just released VirtualBox 4.3, this quick blog entry is about a longer standing ability of VirtualBox when it comes to Snapshots and Cloning, and was prompted by a question posed internally, here in Oracle: "Is there a way I can create a new VM from a point in my snapshot tree?". Here's the scenario: Let's say you have your favourite work VM which is Oracle Linux based and as you installed different packages, such as database, middleware, and the apps, you took snapshots at each point like this: But you then need to create a new VM for some other testing or to share with a colleague who will be using the same Linux and Database layers but may want to reconfigure the Middleware tier, and may want to install his own Apps. All you have to do is right click on the snapshot that you're happy with and clone: Give the VM that you are about to create a name, and if you plan to use it on the same host machine as the original VM, it's a good idea to "Reinitialize the MAC address" so there's no clash on the same network: Now choose the Clone type. If you plan to use this new VM on the same host as the original, you can use Linked Cloning else choose Full.  At this point you now have a choice about what to do about your snapshot tree. In our example, we're happy with the Linux and Database layers, but we may want to allow our colleague to change the upper tiers, with the option of reverting back to our known-good state, so we'll retain the snapshot data in the new VM from this point on: The cloning process then chugs along and may take a while if you chose a Full Clone: Finally, the newly cloned VM is ready with the subset of the Snapshot tree that we wanted to retain: Pretty powerful, and very useful.  Cheers, -FB

• Software solution from the 2000's, should I attempt to patch or remake the whole thing?

  - by ShadowScripter

  I was sent out to discuss a system that a certain company is currently using and what should be done with it. The company manufactures various carton displays. This system was developed to keep track of clients, orders and prices. Lots have happened since the system was created and the system is now, as the manager described it, "locked up" and "problematic", which I translate as "not dynamic" and "unstable". Some info about the system It was developed around the year 2000 Fairly small system, 2-5 users, 6 forms, ~8 tables with average quantities of data Built on early Visual Basic, forms created with the drag and drop design. Interface is basically just a window with a menu and some forms Uses MSSQL database (SQL2005 server) to store data and ODBC driver to query, data was migrated from excel before this system, and before excel it was handled, calculated and written by hand and paper Users work in Microsoft XP environment (and up) Their main problem is that they can't adjust and calculate prices, can't add new carton types etc, correctly anymore because they can't (or rather, they don't know how to) touch the data on the server. I suggested 3 possible solutions Attempt to patch the current system Create a fresh new interface (preferably similar environment, VB.net or VB based) Bring it back to an Excel solution, considering it is such a small system There might be more options, but these are the ones I could think of. My questions are What should I recommend and why? What is or could be the pros and cons of these alternatives? Are there other (possibly better) alternatives?
