  • Securing a Windows Server 2008 R2 Public Web Server

    - by Denny Ferrassoli
    I'm setting up a public web server: Windows Server 2008 R2, IIS7.5. Does anyone have a tutorial / walkthrough / tips on properly securing a public web server? I've seen a few tutorials but mostly focused on Windows Server 2003. What I've done so far: Created a specific user account for the website / app pool, Renamed Admin account, Installed FTPS, Configured firewall to block any non-public service (web / https), Configured firewall to allow access to management interfaces only from specific IP addresses (rdp, IIS management, ftp) Maybe a few other things but can't remember at the moment... ICMP is allowed... Should I disable all except ping? Port scan reveals only web and https ports. Any other suggestions? Thanks

    Jeff Victor: Solaris Virtualization Book Jeff Victor with an update on the status of the book, "Oracle Solaris 10 System Virtualization Essentials." (tags: sun solaris virtualization) Mitch Denny: Architecture vs. Design It's an old post but it still resonates: "In the consumer electronics business, some people are actually hired to go through a system and remove components until it stops working – they do this to remove the cost before they go into mass production. We need more of this in the software business." -- Mitch Denny (tags: architecture design development) @vambenepe: Enterprise application integration patterns for IT management: a blast from the past or from the future? "In a recent blog post, Don Ferguson (CTO at CA) describes CA Catalyst, a major architectural overall which “applies enterprise application integration patterns to the problem of integrating IT management systems”. Reading this was fascinating to me. Not because the content was some kind of revelation, but exactly for the opposite reason. Because it is so familiar." -- William Vambenepe (tags: otn oracle eai)

  • how to install 13.04 on a partitioned hardrive

    - by Denny
    First, not a computer literate person, not even a novice- so please use small words. I recently made the switch to ubuntu, it came preloaded on my new laptop that I order from a big tech dot com site. The version on it is 12.04 (i think) and 64bit. This system has a lot that I like but it is quirky for me to say the least. Apparently I have held broken packages and have no way of knowing how to find them. I discovered this when trying to download (from software center) VLC so that I could watch some movies I had on an external hard-drive. Unmet dependencies error and held broken package errors abound while trying to fix the problem. Ive scoured this site and other and followed almost all the suggestions to a T but still I am unable to fix anything. My computer is partitioned (but I don't even know how to get to the otherside so to speak). I would like to know; can I put the newer 13.04 OS on one side of the partition and then delete the older version on the other side? or, can I install 13.04 over the existing 12.04? What would I need to do this? An obstacle that I have is this, I am currently serving in Afghanistan so going someplace to buy something or running down to a computer store for service support is out of the question. I very much appreciate your help, cause right now this computer is nothing more than a word processor, which would be fine if all i wanted was a word processor. Thanks in advance.

  • What makes puzzle games addictive?

    - by Bryan Denny
    I'm currently developing a puzzle game for Android that is sort of along the lines of Alchemy. I was wondering what makes games like Alchemy or Bejeweled so addicting? How do I keep players interested in the game to want to play it over and over? Is it the scores? Level advancement? The challenges? What should I be doing to try and keep a player engaged with a puzzle game since they are often quite repetitive?

  • Wordpress related question about printf

    - by Denny Mueller
    Today i work through a theme to get a better understanding of wordpress and templating. I discovered this <?php printf( __('Designed by %s', 'Anyword'), '<a href="http://www.blub.tld" target="_blank">Blub</a>', '' ); ?> I know it shows "Designed by Blub" (Where Blub is linked) But what does the __ mean or why is there a string insert? What for is the Anyword? Can someone exactly explain this line for me? thanks in advance best regards

  • how to force operating system to give java more memory?

    - by Denny
    Hello, I've got problem with java jar files and memory. I use netbeans 6.7 to develop an application and this application need more memory to run because it converts another files. Whenever this application convert a 6-10 mb file, it'll crash. So I set netbeans VM Options : -Xms32m -Xmx256m and the application can convert 6-10mb files with no problem. I Clean and Build the project so it can make a jar file of my application. I run the jar on my computer and use jconsole to monitor the memory. The maximum memory to use by the application shows 256 mb. But whenever I move it to some other computers, it shows 65-66 mb on jconsole and the application will crash when convert 6-10 mb files. So I need to use command prompt : java -jar -Xmx256m myjar.jar to execute the jar with maximum memory Why it can be happen, in my computer the maximum memory shows 256 mb but on another computer 65-66 mb? Can I force another computer to give extra maximum memory to my application? Thank you for your answer. I'm sorry for my inadequate English. If you all find my question is hard to understand, please let me know. Best Regards Denny ps: fyi the computer i used to develop the application have 2gb ram, on the other computers i tested have 1-2 gb ram.

  • Can you swap dpi buttons on the Astra Dragon War mouse with 4th and 5th buttons?

    - by Denny Nuyts
    I'm left-handed and I'm in need of a good computer mouse with at least five buttons. However, most computer mice on the market are sadly right-handed and very impracticable to use with the extra buttons on my pinkie side instead of on my thumb side. The Dragon War Astra has two buttons on both sides. Buttons 4 and 5 on the left side and the dpi-buttons on the right side. If I were just able to re-assign them so they swap positions I'd have a great left-handed mouse. Sadly, the program X-Mouse Button Control doesn't allow the user to re-assign dpi buttons. My question is whether there exist other methods to still get it to work for me (third party programs, perhaps?). Or should I get another gaming mouse?

  • Western Digitial My Book: Can't access the data on the drive

    - by Bryan Denny
    My girlfriend has this external hard drive by Western Digital called a My Book. When the external drive is connected, it does not show it as an accessible disk drive on the computer. However, it shows up fine in Device Manager: I can also see it in Disk Management, but the volume is not mapped to a drive letter, nor can I change the drive letter: It only gives me access to Delete Volume: I would rather not lose the data on the drive if possible. What can I do from here to get to the data? Things I've tried/know: Uninstall drivers and re-install them Device does the same thing when attach to either her Win7 laptop or my Win8 laptop I don't think there's an issue with the HDD itself. No clicking noises, etc. I ran Western Digital Data LifeGuard Diangostics (DLGDIAG) and the SMART Status was a "PASS", all of the SMART Disk Information looked fine. I haven't had the time to run the diag tests yet but I do not believe it's a mechanical issue. The hard drive is inside of an enclosure, I have not attempted to pry the drive out yet. How can I get Windows to properly detect this drive?

  • Many commands are not found by zsh

    - by Denny Mueller
    If I tab autocomplete, most of the time I get errors. Let's say I do a vim tab to look for the files in the folder. It just jumps to the next command line. Or let's say I press tab after typing rvm use 2.0.0 --default I will get zsh: correct 'rvm' to 'rvim' [nyae]?. If I say no, I get a command not found error. Also if I press tab after typing ruby -v, zsh wants to correct to _ruby -v. Any known bug or any help for this?

  • System has reached the maximum size allowed for the system part of the registry

    - by Bob Denny
    To be precise System has reached the maximum size allowed for the system part of the registry. Additional storage requests will be ignored. WinXP/64 running fine for 2 years (no /3Gb switch), just started happening. I used ntregopt and the problem went away at least temporarily. However, looking before and after in Windows\System32\Config I see that my System file was reduced only by 10% and is still 170+ Mb. According to my rather extensive research with Google, this is "huge" and should be more like 10-20Mb. The system runs fine. There is a System.bak that is only 11Mb and has the date when I ran ntregopt. That's what I know. Now my question: Is there anything I can do to reduce or rebuild the System registry hive given the above info?

  • Extend hasMap to add putChildren method

    - by denny
    Hi all, i have question, i want to develop a programme about extend the hashmap to add putchildren method.. I wrote main class, but now i wanna write putChildrenValue method.. My question is : i need to implement a putChildrenValue method with 3 parameters, String key, String key, ObjectValue. It will store the system as described above accordingly. When i finished this method When you finish the method data Key1 = "RUBY" value=HashMap which has -> "key2" = 5248 && "VALUE" = German Key1 = "PHYTON" value=HashMap which has -> "key2" = 1234 && -> "VALUE" = German My main class is : public static void main(String [] args) { ExtendedHashMap extendedMap = new ExtendedHashMap(); extendedMap.put (“Row1”, “Column1”, “German”); extendedMap.put (“Row1”, “Column2”, “English”); extendedMap.put (“Row1”, “Column3”, “Spanish”); extendedMap.put (“Row2”, “Column1”, “Ruby”); extendedMap.put (“Row2”, “Column2”, “Phyton”); extendedMap.put (“Row3”, “Column3”, “Java”); } Can anyone help me?

  • How to produce precisely-timed tone and silence in C#

    - by Bob Denny
    I have a C# project that plays Morse code for RSS feeds. I write it using Managed DirectX, only to discover that Managed DirectX is old and deprecated. The task I have is to play pure sine wave bursts interspersed with silence periods (the code) which are precisely timed as to their duration. I need to be able to call a function which plays a pure tone for so many milliseconds, then Thread.Sleep() then play another, etc. At its fastest, the tones and spaces can be as short as 40ms. It's working quite well in Managed DirectX. To get the precisely timed tone I create 1 sec. of sine wave into a secondary buffer, then to play a tone of a certain duration I seek forward to within x milliseconds of the end of the buffer then play. I've tried System.Media.SoundPlayer. It's a loser because you have to Play(), Sleep(), then Stop() for arbitrary tone lengths. The result is a tone that is too long, variable by CPU load. It takes an indeterminate amount of time to actually stop the tone. I then embarked on a lengthy attempt to use NAudio 1.3. I ended up with a memory resident stream providing the tone data, and again seeking forward leaving the desired length of tone remaining in the stream, then playing. This worked OK on the DirectSoundOut class for a while (see below) but the WaveOut class quickly dies with an internal assert saying that buffers are still on the queue despite PlayerStopped = true. This is odd since I play to the end then put a wait of the same duration between the end of the tone and the start of the next. You'd think that 80ms after starting Play of a 40 ms tone that it wouldn't have buffers on the queue. DirectSoundOut works well for a while, but its problem is that for every tone burst Play() it spins off a separate thread. Eventually (5 min or so) it just stops working. You can see thread after thread after thread exiting in the Output window while running the project in VS2008 IDE. I don't create new objects during playing, I just Seek() the tone stream then call Play() over and over, so I don't think it's a problem with orphaned buffers/whatever piling up till it's choked. I'm out of patience on this one, so I'm asking in the hopes that someone here has faced a similar requirement and can steer me in a direction with a likely solution. Thanks in advance...

  • Play .WAV under Mono on Mac OS X (Snow Leopard)?

    - by Bob Denny
    The Mono 2.6 distribution contains System.Media.SoundPlayer, but attempts to play result in no sound (and no errors) on Mac OS X. All I can find with Google search is obscure references to ALSA. I posted to the Mono-OSX list, but there have been on replies there. I hope someone here has an answer. I think I need to tap into CoreAudio, but don't know how from Mono/C#.

  • How can I use the paid version of my app as a "key" to the free version?

    - by Bryan Denny
    Let's say for example that I have some Android app that does X. The free version has ads or basic features. I want to have a paid version that removes the ads and adds extra features. How can I use the paid app as a "license key" to unlock the features in the free app? So the user would install the free app, then install the paid app to get the extra features, but they would still run the free app (which would now be unlocked). What's the best approach to doing this?

  • Best way to bundles photos with app: files or in sqlite database?

    - by Bryan Denny
    Lets say that I have an app that lets you browse through a listing of cars found in a Sqlite database. When you click on a car in the listing, it'll open up a view with the description of the car and a photo of the car. My question is: should I keep the photo in the database as a binary data column in the row for this specific car, or should I have the photo somewhere in the resources directory? Which is better to do? Are there any limitations of Sqlite in terms of how big a binary data column can be? The database will be pretty much be read only and bundled with the app (so the user wouldn't be inserting any cars and their photos).
