  • Isometric Collision Detection

    - by Sleepy Rhino
    I am having some issues with trying to detect collision of two isometric tile. I have tried plotting the lines between each point on the tile and then checking for line intercepts however that didn't work (probably due to incorrect formula) After looking into this for awhile today I believe I am thinking to much into it and there must be a easier way. I am not looking for code just some advise on the best way to achieve detection of overlap

  • Change kernel used by Ubuntu Server on boot

    - by Tim Fountain
    I have a VPS running Ubuntu server 12.04. A while ago, my host installed an alternative kernel (one of Amazon's EC2 kernels) to fix a boot issue I was having. Now, 2 Ubuntu releases later, this kernel (2.6.31-302-ec2) is still being used even though later (3.2.xx) kernels have been installed. How can I make the server use the most recent installed kernel, preferably without just uninstalling the EC2 kernel just in case doing so causes issues?

  • SMTP POP3 & PST. Acronyms from Hades.

    - by mikef
    A busy SysAdmin will occasionally have reason to curse SMTP. It is, certainly, one of the strangest events in the history of IT that such a deeply flawed system, designed originally purely for campus use, should have reached its current dominant position. The explanation was that it was the first open-standard email system, so SMTP/POP3 became the internet standard. We are, in consequence, dogged with a system with security weaknesses so extreme that messages are sent in plain text and you have no real assurance as to who the message came from anyway (SMTP-AUTH hasn't really caught on). Even without the security issues, the use of SMTP in an office environment provides a management nightmare to all commercial users responsible for complying with all regulations that control the conduct of business: such as tracking, retaining, and recording company documents. SMTP mail developed from various Unix-based systems designed for campus use that took the mail analogy so literally that mail messages were actually delivered to the users, using a 'store and forward' mechanism. This meant that, from the start, the end user had to store, manage and delete messages. This is a problem that has passed through all the releases of MS Outlook: It has to be able to manage mail locally in the dreaded PST file. As a stand-alone system, Outlook is flawed by its neglect of any means of automatic backup. Previous Outlook PST files actually blew up without warning when they reached the 2 Gig limit and became corrupted and inaccessible, leading to a thriving industry of 3rd party tools to clear up the mess. Microsoft Exchange is, of course, a server-based system. Emails are less likely to be lost in such a system if it is properly run. However, there is nothing to stop users from using local PSTs as well. There is the additional temptation to load emails into mobile devices, or USB keys for off-line working. The result is that the System Administrator is faced by a complex hybrid system where backups have to be taken from Servers, and PCs scattered around the network, where duplication of emails causes storage issues, and document retention policies become impossible to manage. If one adds to that the complexity of mobile phone email readers and mail synchronization, the problem is daunting. It is hardly surprising that the mood darkens when SysAdmins meet and discuss PST Hell. If you were promoted to the task of tormenting the souls of the damned in Hades, what aspects of the management of Outlook would you find most useful for your task? I'd love to hear from you. Cheers, Michael

  • Using TrueCrypt (software encryption) with an SSD

    - by Shackrock
    I use full drive encryption (FDE) w/ TrueCrypt on my laptop. I have a 2nd gen I7 with AES instruction support, so honestly I can't even notice a speed change on the system with it on. My question, is for those who know about SSD's a lot. I previously (early 2011) read articles about how software encryption will negate the speed benefits that an SSD provides - because of the need for the SSD to send a delete command, then a write command, for every encrypted write - instead of just writing over data like a regular HDD would (or something like this...honestly I can't remember...ha!). Anyway, any improvements in this field? Is it pointless for me to grab an SSD if I'm using FDE? Thanks all.

  • Best books on Managing a Software Development Team? [closed]

    - by JohnFx
    The canonical books on software development is fairly well established. However, after reading through a dreadful book full of bad advice on managing programming teams this weekend I am looking for recommendations for really good books that focus on the management side of programming (recruiting, performance measurement/management, motivation, best practices, organizational structure, etc.) and not as much on the construction of software itself. Any suggestions?

  • So You Want To Build a SPARC Cloud

    - by user12601629
    Did you ever wish you could get the industrial strength power of UNIX/RISC with the flexibility of cloud computing?  Well, now you can!  With recent advances from Oracle it's possible to build an incredibly high-performance, flexible, available virtualized infrastructure based on Solaris and SPARC.  Here's the recipe! Authored in collaboration across the Oracle "Systems Group" team, we now have a complete best practice guide for you.  Click below to download it: Best Practices for Building a Virtualized SPARC Computing Environment Inside you'll find recommendations for how and when to leverage technologies like: SPARC T4 OVM for SPARC hypervisor (version 2.2 and newer) Solaris 11 Ops Center 12c ZFS Storage Appliance Oracle network switches Based on following these best practices, you'll be able to construct a dynamic, virtualized infrastructure that allows for: Easy, GUI-based provisioning on new VMs Automated HA failover in the event of physical server failures Automatic load balancing across a cluster of VM hosts Complete end-to-end monitoring You should download this paper and check it out.  Even if you aren't planning on buying all new hardware, and instead want to transform some existing gear into a dynamic virtualized environment then this paper will give you concrete info on what to do and the trade-offs you'll make. Have fun getting started on your journey to build a SPARC cloud!

  • How can I clear history and settings for the Remote Desktop Viewer (Vinagre)?

    - by user68370
    How do I clear all the settings for Vinagre to take it back to a brand-new, virgin state? I accidentally typed a connection in wrong and I cannot figure out how to delete it. Also some of my connections are not working correctly and I think that if I could flush the whole thing clean it might fix those issues. I have tried uninstalling and reinstalling, but it remembers the previous settings/connections.

  • Detecting Hyper-Threading state

    - by jchang
    To interpret performance counters and execution statistics correctly, it is necessary to know state of Hyper-Threading. In principle, at low overall CPU utilization, for non-parallel execution plans, it should not matter whether HT is enabled or not. Of course, DBA life is never that simple. The state of HT does matter at high over utilization and in parallel execution plans depending on the DOP. SQL Server does seem to try to allocate threads on distinct physical cores at intermediate DOP (DOP less...(read more)

  • Gnome-Shell 3.4 Themes not working in 12.04?

    - by CGriffitt
    Even themes advertised as Gnome-shell 3.4 compatible have graphical issues on Gnome-Shell 3.4. The main thing is that the text is black and nearly invisible, and the icons in the applications screen are crowded and in some cases overlapping. The themes did not do this before upgrade, and the default doesn't do it now. I am using user theme extension, and the themes I have tried are the Ambiance-Color set and London Smoke (both of which are advertised as 3.4 compatible).
