• Getting sendmail to install/work for using php mail()

  - by harryg

  I'm running WordPress on a Ubuntu VPS. When WordPress tries to send an email like a password reset or registration email it never gets delivered. WordPress uses php's mail() function. I figure it's not working as my VPS didn't have sendmail installed. So I went into SSH and installed it with sudo apt-get install sendmail which appeared to succeed. Following more googled advice I edited the php.ini file to have the sendmail path. I located it as being /usr/sbin/sendmail which I believe is typical for many *nix servers. To check I browsed to this directory on FTP. The "sendmail" directory appears to be a shortcut. Is this correct/expected? Either way the php mail function is not working. I have created a phpinfo file and a test mail php file which contains just a mail() function with my email as the recipient. Note: my VPS doesn't yet have a domain, just an IP address. Would this affect sendmail functionality? My phpinfo is here for your reference: http://95.142.166.209/phpinfo.php Do I also need postfix? I don't think I have it... Here is some of the mail log. I executed the mail function towards the end: Nov 27 18:41:02 sergeserver sm-msp-queue[5450]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 19:00:01 sergeserver sm-msp-queue[5497]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 19:01:01 sergeserver sm-msp-queue[5497]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 19:20:01 sergeserver sm-msp-queue[5532]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 19:21:01 sergeserver sm-msp-queue[5532]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 19:40:01 sergeserver sm-msp-queue[5568]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 19:41:01 sergeserver sm-msp-queue[5568]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 20:00:01 sergeserver sm-msp-queue[5605]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 20:01:01 sergeserver sm-msp-queue[5605]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 20:20:01 sergeserver sm-msp-queue[5641]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 20:21:01 sergeserver sm-msp-queue[5641]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 20:40:01 sergeserver sm-msp-queue[5675]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 20:41:01 sergeserver sm-msp-queue[5675]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 21:00:01 sergeserver sm-msp-queue[5712]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 21:01:01 sergeserver sm-msp-queue[5712]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 21:20:02 sergeserver sm-msp-queue[5747]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 21:21:02 sergeserver sm-msp-queue[5747]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 21:40:01 sergeserver sm-msp-queue[5782]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 21:41:01 sergeserver sm-msp-queue[5782]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 22:00:01 sergeserver sm-msp-queue[5831]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 22:01:01 sergeserver sm-msp-queue[5831]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 22:20:01 sergeserver sm-msp-queue[5866]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 22:21:01 sergeserver sm-msp-queue[5866]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 22:37:19 sergeserver sendmail[5903]: My unqualified host name (sergeserver) unknown; sleeping for retry Nov 27 22:38:19 sergeserver sendmail[5903]: unable to qualify my own domain name (sergeserver) -- using short name Nov 27 22:38:19 sergeserver sendmail[5903]: qARLcJYI005903: from=adminftp, size=158, class=0, nrcpts=0, msgid=<201211272138.qARLcJYI005903@sergeserver>, relay=adminftp@localhost

• The cable of my USB port hub is too short - what to do?

  - by Anna

  Hi, I just bought a new USB port hub "MSY USB 2.0 4-port hub". It has two inputs: A small USB entrance input for external power (?) The problem is that the cable that comes with the hub (small USB on one end, large USB on the other - to input into my computer), is too short for my needs. Is there a solution to this? buying a longer cable might be risky, I know that it might cause problems with power. Is there anything else I can do to make it work? Thanks.

• What could cause a file system to spontaneously unmount or become invalid for a short time?

  - by Ichorus

  We've got DB2 LUW running on a RHEL box. We had a crash of DB2 and IBM came back and said that a file that DB2 was trying to access (through open64()) unmounted or became invalid. We have done nothing but restart the database and things seem to be running fine. Also, the file in question looks perfectly normal now: $ cd /db/log/TEAMS/tmsinst/NODE0000/TEAMS/T0000000/ $ ls -l total 557604 -rw------- 1 tmsinst tmsinst 570425344 Jan 14 10:24 C0000000.CAT $ file C0000000.CAT C0000000.CAT: data $ lsattr C0000000.CAT ------------- C0000000.CAT $ ls -l total 557604 -rw------- 1 tmsinst tmsinst 570425344 Jan 14 10:24 C0000000.CAT With those facts in hand (please correct me if I am mis-interpreting the data at hand) what could cause a file system to 'spontaneously unmount or become invalid for a short time'? What should my next step be? This is on Dell hardware and we ran their diagnostic tools against the hardware and it came back clean.

• Casting a char to an unsigned short: what happens behind the scenes?

  - by hb

  Given this field: char lookup_ext[8192] = {0}; // Gets filled later And this statement: unsigned short *slt = (unsigned short*) lookup_ext; What happens behind the scenes? lookup_ext[1669] returns 67 = 0100 0011 (C), lookup_ext[1670] returns 78 = 0100 1110 (N) and lookup_ext[1671] returns 68 = 0100 0100 (D); yet slt[1670] returns 18273 = 0100 0111 0110 0001. I'm trying to port this to C#, so besides an easy way out of this, I'm also wondering what really happens here. Been a while since I used C++ regularly. Thanks!

• How do I split a short into its two bytes ?

  - by aPoC

  Hi. I have to split up a short into its two bytes. They have to be in Network order. I need that for a small server telling the current size of the rest packet's data. List<byte> o = new List<byte>(); o.Add(0x03); // here this short o.AddRange(MapData); o.Add(0xFF); Send(o);

• byte and short data types in Java can accept the value outside the range by explicit cast. The higher data types however can not. Why?

  - by Lion

  Let's consider the following expressions in Java. byte a = 32; byte b = (byte) 250; int i = a + b; This is valid in Java even though the expression byte b = (byte) 250; is forced to assign the value 250 to b which is outside the range of the type byte. Therefore, b is assigned -6 and consequently i is assigned the value 26 through the statement int i = a + b;. The same thing is possible with short as follows. short s1=(short) 567889999; Although the specified value is outside the range of short, this statement is legal. The same thing is however wrong with higher data types such int, double, folat etc and hence, the following case is invalid and causes a compile-time error. int z=2147483648; This is illegal, since the range of int in Java is from -2,147,483,648 to 2147483647 which the above statement exceeds and issues a compile-time error. Why is such not wrong with byte and short data types in Java?

• How to re-arrange Excel database from 1 long row, into 3 short rows of unequal lengths and automatically repeat the process?

  - by user326884

  This question is an extension/continuation of my previous question at How to re-arrange Excel database from 1 long row, into 3 short rows and automatically repeat the process? which was answered by Jason Lewis of which I'm grateful. But being a dummy in "Indirect' Excel function, I need assistance again : For example :- In Sheet A, Row 1 has the following data in each cell (all together 72 cells occupied): A1 B1 C1 D1 E1 F1 G1 H1 I1 J1 K1 L1 M1 N1 O1 P1 Q1 R1 S1 T1 U1 V1 W1 X1 Y1 Z1 AA1 AB1 AC1 AD1 AE1 AF1 AG1 AH1 AI1 AJ1 AK1 AL1 AM1 AN1 AO1 AP1 AQ1 AR1 AS1 AT1 AU1 AV1 AW1 AX1 AY1 AZ1 BA1 BB1 BC1 BD1 BE1 BF1 BG1 BH1 BI1 BJ1 BK1 BL1 BM1 BN1 BO1 BP1 BQ1 BR1 BS1 BT1 To be re-arranged into Sheet B in the following format: Row 1 : A1 B1 C1 D1 E1 F1 G1 H1 I1 J1 K1 L1 M1 N1 O1 P1 Q1 R1 S1 T1 U1 V1 W1 X1 Y1 Z1 AA1 AB1 AC1 AD1 AE1 AF1 AG1 AH1 AI1 Row 2 : AJ1 AK1 AL1 AM1 AN1 AO1 AP1 AQ1 AR1 AS1 AT1 AU1 AV1 AW1 AX1 AY1 AZ1 BA1 BB1 BC1 BD1 BE1 BF1 BG1 BH1 BI1 BJ1 BK1 Row 3 : BL1 BM1 BN1 BO1 BP1 BQ1 BR1 BS1 BT1 The Sheet A (database sheet) has a lot of rows (example 3,000 rows, each rows has 72 cells occupied with data), hence the Sheet B (reformatted database) is estimated to have 9,000 rows (i.e. 3 x 3,000) of unequal lengths. Thanking you in anticipation of your speedy response.

• How to short-circuit Eclipse AutoComplete when "by relevance" Sorting is enabled?

  - by JRtim

  I know there's a number of autocomplete articles scattered around stack and eclipse relevant communities. I haven't seen a solution that I have been able to make work. Essentially it goes like this... I like sorting by relevance (since it usually has a decent priority), but sometimes I want to short circuit the autocomplete without having to hit x 2. If I have a class that has a couple methods like, getThis(), getThat, and get(), and eclipse picks up that I usually use getThis(), but every once in a while I want the get() method. So I type "Class" "period" "get(" -- whoops eclipse just filled in getThis(). When the sorting is alphabetically, this isn't an issue, but "by relevance" is a nice default. Just wondering if I'm missing the boat on something. Obviously one solution is to increase the latency on the autocomplete popup, but get() might just be an example. There might a situation where the method I want is a few parameters and maybe more than 3 keystrokes. Thank you.

• Please help me correct the small bugs in this image editor

  - by Alex

  Hi, I'm working on a website that will sell hand made jewelry and I'm finishing the image editor, but it's not behaving quite right. Basically, the user uploads an image which will be saved as a source and then it will be resized to fit the user's screen and saved as a temp. The user will then go to a screen that will allow them to crop the image and then save it to it's final versions. All of that works fine, except, the final versions have 3 bugs. First is some black horizontal line on the very bottom of the image. Second is an outline of sorts that follows the edges. I thought it was because I was reducing the quality, but even at 100% it still shows up... And lastly, I've noticed that the cropped image is always a couple of pixels lower than what I'm specifying... Anyway, I'm hoping someone whose got experience in editing images with C# can maybe take a look at the code and see where I might be going off the right path.

• Confirm disk is broken when it passes all diagnostics

  - by Halfgaar

  I have a system with a potentially broken disk, but the disk passes all manner of diagnostics. I have been unable to confirm that the disk is broken. What are my options? I could just replace the disk, but because this situation is very similar to another more severe situation I have (long story), I'd like to actually make a proper diagnosis as opposed to randomly binning hardware. The issue and history is this: I had a Debian Linux PC (500 MHz P3) acting as router, nagios and munin. It crashed every couple of weeks. No logs or dmesg could be obtained (because it's an old Compaq that only boots when you configure it as keyboardless, making connecting a keyboard later, once it's booted, impossible). At the time, I just replaced the computer with another Compaq (P4 2.4 GHz) because I thought the hardware was faulty. However, it still crashed every couple of weeks. the difference is that on this computer, I can still SSH into it. It gives all kinds of errors on hda. I'd like to confirm that the disk is broken, but nothing I do confirms this: SMART error logs shows no errors. Normally when a disk starts acting up, SMART my pass, but it still records a read-error in the error log. SMART self-test (smartctl -t long /dev/sda) completes without errors. re-allocated sector count (a tell-tale parameter) has been 31 all its life, even when the disk was still in use in my desktop PC years ago, and it still is. The figure never changed. dd if=/dev/sda of=/dev/null bs=4096 passes with flying colors. What else can I do to assess the health of the drive? Again, this is not about making this router fully functional again, this is a disk forensic question, because it just so happens that I have another server that potentially has the same problem, and knowing the answer to this will possibly help me greatly. For the record, below are logs and such.

• Getting SIGILL in float to fixed conversion

  - by foliveira

  I'm receiving a SIGILL after running the following code. I can't really figure what's wrong with it. The target platform is ARM, and I'm trying to port a known library (in which this code is contained) void convertFloatToFixed(float nX, float nY, unsigned int &nFixed) { short sx = (short) (nX * 32); short sy = (short) (nY * 32); unsigned short *ux = (unsigned short*) &sx; unsigned short *uy = (unsigned short*) &sy; nFixed = (*ux << 16) | *uy; } Any help on it would be greatly appreciated. Thanks in advance

• What is the best way to store meshes or 3d models in a class

  - by Robse

  I am wondering, how I should store my mesh into memory after loading it from whatever file. I have Questions floating in my head: Should a mesh could have sub meshes or does the 3d model just store a list of meshes all on the same level Is there one material assigned to one mesh 1:1? What do I have to consider, if I want to store skeletal animations? Btw it's a OpenGL|ES2 iOS game using GLKit. I came up with some basic struct types: (But I think they are way to simple and I need to add padding or change the vector3 to vector4.) typedef union _N3DShortVector2 { struct { short x, y; }; struct { short s, t; }; short v[2]; } N3DShortVector2; typedef union _N3DShortVector3 { struct { short x, y, z; }; struct { short r, g, b; }; struct { short s, t, p; }; short v[3]; } N3DShortVector3; typedef GLKVector3 N3DFloatVector3; typedef struct _N3DMeshRecordSV3 { N3DShortVector3 v1, v2, v3; } N3DMeshRecordSV3; typedef struct _N3DMeshRecordSV3FN3ST2 { N3DShortVector3 v1, v2, v3; N3DFloatVector3 n1, n2, n3; N3DShortVector2 t1, t2, t3; } N3DMeshRecordSV3FN3ST2;

• Screen Aspect Ratio

  - by Bill Evjen

  Jeffrey Dean, Pixar Aspect Ratio is very important to home video. What is aspect ratio – the ratio from the height to the width 2.35:1 The image is 2.35 times wide as it is high Pixar uses this for half of our movies This is called a widescreen image When modified to fit your television screen They cut this to fit the box of your screen When a comparison is made huge chunks of picture is missing It is harder to find what is going on when these pieces are missing The whole is greater than the pieces themselves. If you are missing pieces – you are missing the movie The soul and the mood is in the film shots. Cutting it to fit a screen, you are losing 30% of the movie Why different aspect ratios? Film before the 1950s 1.33:1 Academy Standard There were all aspects of images though. There was no standard. Thomas Edison developed projecting images onto a wall/screen He didn’t patent it as he saw no value in it. Then 1.37:1 came about to add a strip of sound This is the same size as a 35mm film Around 1952 – TV comes along NTSC Television followed the Academy Standard (4x3) Once TV came out, movie theater attendance plummets So Film brought forth color to combat this. Also early 3D Also Widescreen was brought forth. Cinema-Scope Studios at the time made movies bigger and bigger There was a Napoleon movie that was actually 4x1 … really wide. 1.85:1 Academy Flat 2.35:1 Anamorphic Scope (aka Panavision/Cinemascope) Almost all movies are made in these two aspect ratios Pixar has done half in one and half in the other Why choose one over the other? Artist choice It is part of the story the director wants to tell Can we preserve the story outside of the theaters? TVs before 1998 – they were very square Now TVs are very wide Historical options Toy Story released as it was and people cut it in a way that wasn’t liked by the studio Pan and Scan is another option Cut and then scan left or right depending on where the action is Frame Height Pixar can go back and animate more picture to account for the bottom/top bars. You end up with more sky and more ground The characters seem to get lost in the picture You lose what the director original intended Re-staging For animated movies, you can move characters around – restage the scene. It is a new completely different version of the film This is the best possible option that Pixar came up with They have stopped doing this really as the demand as pretty much dropped off Why not 1.33 today? There has been an evolution of taste and demands. VHS is a linear item The focus is about portability and not about quality Most was pan and scan and the quality was so bad – but people didn’t notice DVD was introduced in 1996 You could have more content – two versions of the film You could have the widescreen version and the 1.33 version People realized that they are seeing more of the movie with the widescreen High Def Televisions (16x9 monitors) This was introduced in 2005 Blu-ray Disc was introduced in 2006 This is all widescreen You cannot find a square TV anymore TVs are roughly 1.85:1 aspect ratio There is a change in demand Users are used to black bars and are used to widescreen Users are educated now What’s next for in-flight entertainment?

• How to get short month names in Joda Time?

  - by Mr Morgan

  Hello Does anyone know if there's a method in Joda Time or Java itself which takes either an int or a String as an argument, e.g. 4 or "4" and gives the name of the month back in short format, i.e. JAN for January? I suppose long month names can be truncated and converted to upper case. Thanks Mr Morgan.

  - by DR

  I've often read that in the Sun JVM short-lived objects ("relatively new objects") can be garbage collected more efficiently than long-lived objects ("relatively old objects") Why is that so? Is that specific to the Sun JVM or does this result from a general garbage collection principle?

• How to generate an Intent that jumps into a specific short message conversation?

  - by Janusz

  I would like to create an Intent that opens the messages application in a specific conversation. If a short message notification is clicked Logcat reveals the following: INFO/ActivityManager(31909): Starting activity: Intent { act=android.intent.action.VIEW dat=content://mms-sms/conversations/3 flg=0x34000000 cmp=com.android.mms/.ui.ConversationList bnds=[0,586][600,682] } This brought me a little bit further using content://mms-sms/conversations/3 as the data starts up the messages app in the correct conversation. I now only need to find out which conversation a message belongs to.
