  • Texture the quad with different parts of texture

    - by PolGraphic
    I have a 2D quad. Let say it's position is (5,10) and size is (7,11). I want to texture it with one texture, but using three different parts of it. I want to texture the part of quad from x = 5 to x = 7 with part of texture from U = 0 to U = 0.5 (replaying it after achieving 0.5, so I will have 4 same 0.5-lenght fragments). The second one with some other part of texture (also repeating it) and third in the same style. But, how to achieve it? I know that: float2 tc = fmod(input.TexCoord, textureCoordinates.zw - textureCoordinates.xy) + textureCoordinates.xy; //textureCoordinates.xy = fragments' offset Will give me the texture part replaying.

  • apache2 server returns (400) syntax error

    - by Thomas E
    There are 900 paths in the googles index to our homepage containing illegal characters. Example: http://www.seriesam.com/filmaffisch/TC%4NK Note the character "%4N". I have no idea where they come from, but would like to update google index with a correct URL using "canonical" in the html code. But the problem is our apache2 server immediately sends a 400 error if you click the link above. How can I configure apache2 not to give an error code, but instead treat the link above as "correct"? Maybe replacing the char %4N with nothing.

  • How to grant AllPermission to not extracted war file in tomcat

    - by André
    Hello, I'm developing a web application and have created a war file. If I deploy it to my tomcat server, it is used without being unpacked (which is the setting I want to have for this server). For unpacked web apps I have a policy file to grant AllPermission to my application grant codeBase "file:${catalina.base}/webapps/tc/-" { permission java.security.AllPermission; }; But what has the codeBase to be for unpacked war files? Thanks, André

  • How to see the code generated by the compiler

    - by atch
    Guys in one of excersises (ch.5,e.8) from TC++PL Bjarne asks to do following: '"Run some tests to see if your compiler really generates equivalent code for iteration using pointers and iteration using indexing. If different degrees of optimization can be requested, see if and how that affects the quality of the generated code"' Any idea how to eat it and with what? Thanks in advice.

  • half-sine pulse shaping

    - by kos
    hi, i wanted to know what is the pulse shape of the modem.oqpskmod? and if it is not half-sine pulse shape, how is it possible to make it half-sine pulse shape as it is stated in ieee 802.15.4(zigbee) standard where it shows it as follows p(t)=sin(pi*t/2*Tc) if 0<=t<=2Tc p(t)=0 if otherwise ? thanks a lot!

  • How to store an array as the value in Tokyo Cabinet?

    - by punkish
    Is there any way I can store an array of numbers in a Tokyo Cabinet db? For example, I have predictable arrays of values such as 1 => [1, 2, 444, 0.987], 2 => [2, 23, 123, -0.234], 3 => [3, 1, 34, 1.456] I would like to store the above in a TC fixed length db. Is there a way to store the above as arrays instead of as strings?

  • How can I turn a single element in a list into multiple elements using Python?

    - by Trivun
    I have a list of elements, and each element consists of four seperate values that are seperated by tabs: ['A\tB\tC\tD', 'Q\tW\tE\tR', etc.] What I want is to create a larger list without the tabs, so that each value is a seperate element: ['A', 'B', 'C', 'D', 'Q', 'W', 'E', 'R', etc.] How can I do that in Python? I need it for my coursework, due tonight (midnight GMT) and I'm completely stumped.

  • How to effectively measure difference in a run-time.

    - by Knowing me knowing you
    Guys, in one of the excersises in TC++PL B.S. asks to: "Write a function that either returns a value or that throws that value based on an argument. Measure the difference in run-time between the two ways." Great pity he never explaines how to measure such things. I'm not sure if I'm suppose to write simple "time start, time end" counter or maybe there are more effective and practical ways to do it? Thanks in advance.

  • QoS - split bandwidth across all IPs during high load

    - by Matthew Iselin
    We have a Linux-based router which is currently working fairly well, but our network only has a 1.5 mbps incoming connection. The network is small, but during high load periods some systems can end up dominating the bandwidth. For example, a client downloading a file can easily saturate the connection leaving everyone else with barely any access to the outside world. Naturally, I'd like to fix this. I believe a combination of iptables rules and tc is in order, but I have no idea how to go about distributing the bandwidth evenly across the clients. It would be nice if there was a way to divide the bandwidth only across clients that are actually utilising the connection as well, rather than hard limit each connection to (bandwidth / number of clients).

  • Windows DNS Server 2008 R2 fallaciously returns SERVFAIL

    - by Easter Sunshine
    I have a Windows 2008 R2 domain controller which is also a DNS server. When resolving certain TLDs, it returns a SERVFAIL: $ dig bogus. ; <<>> DiG 9.8.1 <<>> bogus. ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 31919 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;bogus. IN A I get the same result for a real TLD like com. when querying the DC as shown above. Compare to a BIND server that is working as expected: $ dig bogus. @128.59.59.70 ; <<>> DiG 9.8.1 <<>> bogus. @128.59.59.70 ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 30141 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;bogus. IN A ;; AUTHORITY SECTION: . 10800 IN SOA a.root-servers.net. nstld.verisign-grs.com. 2012012501 1800 900 604800 86400 ;; Query time: 18 msec ;; SERVER: 128.59.59.70#53(128.59.59.70) ;; WHEN: Wed Jan 25 14:09:14 2012 ;; MSG SIZE rcvd: 98 Similarly, when I query my Windows DNS server with dig . any, I get a SERVFAIL but the BIND servers return the root zone as expected. This sounds similar to the issue described in http://support.microsoft.com/kb/968372 except I am using two forwarders (128.59.59.70 from above as well as 128.59.62.10) and falling back to root hints so the preconditions to expose the issue are not the same. Nevertheless, I also applied the MaxCacheTTL registry fix as described and restarted DNS and the whole server as well but the problem persists. The problem occurs on all domain controllers in this domain and has occurred since half a year ago, even though the servers are getting automatic Windows updates. EDIT Here is a debug log. The client is 160.39.114.110, which is my workstation. 1/25/2012 2:16:01 PM 0E08 PACKET 000000001EA6BFD0 UDP Rcv 160.39.114.110 2e94 Q [0001 D NOERROR] A (5)bogus(0) UDP question info at 000000001EA6BFD0 Socket = 508 Remote addr 160.39.114.110, port 49710 Time Query=1077016, Queued=0, Expire=0 Buf length = 0x0fa0 (4000) Msg length = 0x0017 (23) Message: XID 0x2e94 Flags 0x0100 QR 0 (QUESTION) OPCODE 0 (QUERY) AA 0 TC 0 RD 1 RA 0 Z 0 CD 0 AD 0 RCODE 0 (NOERROR) QCOUNT 1 ACOUNT 0 NSCOUNT 0 ARCOUNT 0 QUESTION SECTION: Offset = 0x000c, RR count = 0 Name "(5)bogus(0)" QTYPE A (1) QCLASS 1 ANSWER SECTION: empty AUTHORITY SECTION: empty ADDITIONAL SECTION: empty 1/25/2012 2:16:01 PM 0E08 PACKET 000000001EA6BFD0 UDP Snd 160.39.114.110 2e94 R Q [8281 DR SERVFAIL] A (5)bogus(0) UDP response info at 000000001EA6BFD0 Socket = 508 Remote addr 160.39.114.110, port 49710 Time Query=1077016, Queued=0, Expire=0 Buf length = 0x0fa0 (4000) Msg length = 0x0017 (23) Message: XID 0x2e94 Flags 0x8182 QR 1 (RESPONSE) OPCODE 0 (QUERY) AA 0 TC 0 RD 1 RA 1 Z 0 CD 0 AD 0 RCODE 2 (SERVFAIL) QCOUNT 1 ACOUNT 0 NSCOUNT 0 ARCOUNT 0 QUESTION SECTION: Offset = 0x000c, RR count = 0 Name "(5)bogus(0)" QTYPE A (1) QCLASS 1 ANSWER SECTION: empty AUTHORITY SECTION: empty ADDITIONAL SECTION: empty Every option in the debug log box was checked except "filter by IP".

In this case, I didn't see any packets going out from my DNS server even though bogus. was not in the cache (the debug log was already running and this is the first time I queried this server for bogus. or any TLD). It just returned SERVFAIL without consulting any other DNS server, as in the Microsoft KB article linked above.

  • How to configure squid for retrieving (and caching) directly my static resources?

    - by fabien7474
    I have an Apache/Tomcat/Spring tc Server running on CentOS EC2 VM. I would like to install squid on the same machine as a proxy for retrieving (directly i.e. without forwarding the request to Apache/Tomcat) and caching static content ONLY identified by URIs : /images, /css or /js. Other URIs should be forwarded to the normal Web Server and not cached. Since I am a newbie, I didn't find from squid documentation how to configure squid for this desired behavior (and if it is even possible). Could you please help me and tell me how should I configure squid for this purpose? Thank you.

  • Measuring cumulative network statistics per user or per process

    - by zsimpson
    I've been googling for hours -- Under Linux I want to know the cumulative bytes sent and received by user or by process over all ip protocols. The best I've found in my searches is that it's possible to use iptables to mark packets for a user, for example: iptables -t mangle -A OUTPUT -p tcp -m owner --uid-owner test -j MARK --set-mark 1 It appears that "tc" can then shape traffic with that but I just want the statistic -- I don't want to shape the traffic. I want something like: "user U has transmitted used XMB since time Y". I can't figure out how to get statistics from these marked packets. Also, I've looked at nethogs but they seem to be measuring the instantaneous flow and I need cumulative counts. Anyone have ideas?

  • What do encrypted files' data look like?

    - by Frost Shadow
    I know there are a lot of encryption programs available, that I would guess use different methods for encryption, and thus have different types of output files (.fve .tc .cha .dmg (bitlocker, truecrypt, challenger, ect.)), but if someone didn't know what the file was and just looked at the data, what would it look like? Does it just look like random bits, or can you still pick out a pattern? If it does look random, how is it if I moved the encrypted file to another computer, the other computer can tell it's a file, and is able to decrypt it (how would it even know where to start or stop, if it all looked random)? Also, how is the structure affected by encrypting files twice, using the same method, or a different one? Thanks for any help, and if you know any books or site about encryption for complete idiots, I'd appreciate it!

  • Choosing Truecrypt volume names and keyfile names

    - by Howiecamp
    Any recommendations on what to name Truecrypt volumes (container files) and where to locate them? Certainly a name like "this is a truecrypt volume.tc" isn't a good idea. Any recommended storage locations? Same question for keyfiles that are generated with Truecrypt. Finally, lets say you choose an existing file, ymca.mp3, as your keyfile. Given that that file is innocuous and normal looking, isn't it easy to forget that's your key file so when you get sick of the Village People and delete the song you're hosed?

  • Setting up Raid 1 Array for Home Server

    - by user1048116
    I'm not sure if this is even possible, but it's worth asking on here! Essentially I have a old machine at home (well, not old hardware wise, but I recently built a new gaming rig), which I decided to install a copy of W2008 R2 on and use as a file/backup server and media center'ish machine. As of now, it has a single drive partitioned into C and D, with D being the Data partition. I have happened to find an old 1TB SATA drive lying around at home, and was wondering if it's possible to setup a Raid 1 array in my rig within Windows without needing to lose everything on my first drive (or maybe even just mirror a specific partition, say the Data partition, as this is just what stores my photos etc). Maybe this isn't possible, but you never know :) Regards, T.C

  • Tomcat 5.5 - second application returs 404

    - by Tomas Tintera
    There are two versions of web application. Want to have both on one machine so I can test upgrade. If there is one of them copied to Tomcat's webapplications directory and then Tomcat is started, it works fine. So if there is only have only ...webapplicatios\ROOT\... ...webapplicatios\myApp25\... it works fine. Or when there is only ...\webapps\ROOT\... ...\webapps\myApp26\... it works fine too. If I upload both ...\webapps\ROOT and ...\webapps\myApp25 ...\webapps\myApp26 only one of the apps will work. The other one returns 404, page not found. It's running on Windows7 and I use Tomcat 5.5. Tomcat is just default installation. Any idea what to check? How to make both running both apps? Thank you in advance for any help. I'm beginner regarding TC.
