  • Apache with mod_perl eating memory when idle

    - by syneticon-dj
    An Apache webserver running a mod_perl application is exposing abnormal memory usage - after the "day load" ceases, the system's memory is being exhausted by the Apache processes and oom_killer is being invoked. As the load returns the following morning, the memory usage normalizes - probably because Apache workers get recycled periodically if a sufficient number of hits is generated: This is the graph for apache hits per second to correlate: The remaining 2 hits per second throughout the night are induced by HAProxy checks - it runs HEAD http://mydomain.example.com/running HTTP/1.0 requests against the server every half a second with "running" being a static file (i.e. not invoking any perl code). It also seems that disabling these checks remedies the memory usage problem, but obviously cannot be a solution. All of 3 similarly configured servers (behind HAProxy) expose this behavior. The running OS is Ubuntu 10.10, Apache version 2.2.16. This seems to be a memory leak but I have no idea how to start debugging it - any hints?

  • scp stalls and ssh sessions freeze up (but eventually start again)

    - by coleifer
    I am running ubuntu on various computers on a home wireless network. Some are on 9.04x64, some 10.04x64 and one 9.04x32. Running scp with a large file starts out at 2.1 mbps and drops down to about 200k, stalling and dropping until the transfer is complete. I've noticed this when I have a secure shell open on any of these servers as well. I have tried this with 2 different routers, both brand new, different brands.

  • Customising error bars

    - by itid
    Hello I've been told I HAVE TO have custom error bars for an assignment I have to hand in. Okay, I have a scatter graph with twelve points, and the error for each one is different. It's the same plus and minus, but different for each one. The twelve different error values are sitting nicely in a column. I have been told I can reference that column in "custom error bars" simply by indicating the range of values, like F2-F14. However, I get an error message every time. When I open Custom Error Bars, it is set up like this: ={} obviously waiting for a function. The error message says remove the equals sign. How should I enter the value range, please ?

  • Problem to connect to shared printer

    - by PeterMmm
    Maybe someone knows a reason for following behaviour: I'm going to add a printer thru the normal printer wizard. At the step where to connect to a shared printer i select browse and take a printer from the printers attached to another host. That won't work. But if i write the complete address (\\host\printer) the printer get attached. Any idea why i cannot select from the list ?

  • Find out how many DNS Queries/month via WHM or SSH?

    - by Kerry
    Is it possible? We have complete control over our DNS server and the server actually being pointed to. We are interested in how many DNS Queries we are currently getting, as we want to move to Ultra DNS, but we need to know how many queries we're likely to get in a month. Is this possible to figure out? Do I need to start a service before tracking begins? Or use shell to access the data?

  • Will a hosting company work with a site that'll (eventually and ideally) have many frequent visitors

    - by user66083
    I have a website I'd like to develop that might eventually get fairly large (in terms of what's stored and how many people visit). My question is, will staying with a hosting company (namely, FatCow) be a complete disaster? Or is there an alternative? I know very little about this aspect of web dev, so it would be great if any technology I need to learn was mentioned with some detail. Thank you very much.

  • Transparent, unicode X terminal not tied to a Desktop Environment?

    - by jamuraa
    I've been looking for this for a while now and I just haven't been able to find one. The last few that I used were: aterm - this one was fast and had good transparency support, but it doesn't support Unicode at all as far as I can tell. The dependency graph is also reasonable. gnome-terminal - was good, and had good transparency support plus unicode, but it pulls in about everything in gnome, and I don't use anything else in gnome. It was also somewhat slow (noticable lag in updating at times) and wouldn't use fonts that I wanted. Eterm - same thing as aterm, good dependencies and transparency but no unicode. Does anyone have suggestions, or will I be stuck with gnome-terminal's dependencies and slowness?

    - by GTX OC
    I need to reinstall Windows 7 but the problem is that all my partitions are set to Dynamic disk type.Windows cannot install on Dynamic disc type partitions.During the installation process there is an option to format the drive but I cannot change the disc type.Is there any way to convert the partitions back into primary so that I can re-install Windows?I am a complete fool.I don't even know why I converted the partition in which Windows was installed into dynamic type. I have a 1TB HDD having 4 partitions and all of them are dynamic. Thanks in advance.

  • Innodb statistics

    - by user64204
    We're running InnoDB as a MySQL engine and using phpMyadmin to administer our database. Under Status - Query statistics, phpMyadmin gives us the following: We would like to know where these figures come from because we would like to create a Munin graph showing the evolution of these statistics over time. When we run the SHOW STATUS; query here is what we get: Innodb_rows_deleted 247555 Innodb_rows_inserted 822911 Innodb_rows_read 694934413 Innodb_rows_updated 15048 As you can see there is a substantial difference although both were taking almost at the same time. Q: Do you know where phpMyadmin gets its values from?

  • What all is there to know about ping while troubleshooting an internet connection?

    - by tMJ
    What all is there to know about ping and the IP address to ping while troubleshooting/diagnosing a problem in the internet connection? For example: I run the command ping 192.168.1.1 -t in the command prompt, and if there is no reply I get something is odd, but I don't understand what is and where it is. I am looking for a complete list (okay, as many as you got), of IP address to ping while troubleshooting my network connection, and an insight into what the status message returned by them implies.

  • Visual indication of network activity

    - by at.
    is there a simple application which can sit on top of a fullscreen game to give me an indicator of when there is a lot of network activity? I can only seem to find system tray apps or programs which work outside of fullscreen games. Preferably something transparent so i can see through it. A little background info: I used to have my PC sitting sideways on my desk so I can see lights from the network card. The lights stopped working a while ago and all I need is a little blinking application to tell me when there is activity. I do not need a detailed graph or bandwidth usage, just activity notification. I've looked everywhere for something, maybe you guys are better at searching than me.

  • Soap client call has slow performance

    - by Alon_A
    OS is Centos 6.2 with PHP 5.3.15. We have a Facebook application that is using PHP soap web services. We sometimes experince slow preformance when connecting to these services, but we cant understand what exacly is causing the problem. We've try to analyse the behavior using the profiling tool Kcachgrind. Here is a call graph from the index.php page that took 21 seconds to load. You can clearly see that calling the soap client is the bottle neck. I've also noticed that exactly before the page finishes to load, this file is being created in our serve's /tmp folder: wsdl-apache-d1032d85dfd16c0d91a6b70facc70e43 These are the permission of /tmp drwxrwxrwt 6 root root 40960 Aug 30 10:39 tmp I know its not the most specific question, but if any one had similar performance issues with soap client, We would love some ideas about what can cause this kind of performance problem, what can we do to investigate more accurately or how to overcome the problem ? Thanks.

  • iptables management utility (character based): Suggestions?

    - by samsmith
    I need IPTables , like everyone else, but I don't use it enough to really keep my knowledge complete and fresh. The setup utility in centos is too basic (doesn't seem to allow me to open up custom ports, just standard ones). Suggestions of a tool or utility to simply iptables management? I looked over APF (http://www.rfxn.com/projects/advanced-policy-firewall/). Is that something that is useful? thanks!

  • Excel axis problem

    - by itid
    I am graphing the height above sea level obtained by GPS at 12 measuring stations, which are distributed along a straight line but NOT equidistantly. Excel does a nice job of creating a suitable Y axis. But, it insists on placing the 12 stations equidistantly along the X axis. Consequently, the line graph does not represent the true cross section of the terrain. It is only true at the stations themselves. Surely there must be a way that I can enter the actual distances between the stations into a column, and get Excel to read from that column and space the values accordingly? It is such a basic mapping procedure for geologists and many others. Thanks

  • How to stop OpenGL from applying blending to certain content? (cocos2d/iPhone/OpenGL)

    - by RexOnRoids
    Supporting Info: I use cocos2d to draw a sprite (graph background) on the screen (z:-1). I then use cocos2d to draw lines/points (z:0) on top of the background -- and make some calls to OpenGL blending functions before the drawing to SMOOTH out the lines. Problem: The problem is that: aside from producing smooth lines/points, calling these OpenGL blending functions seems to degrade the underlying sprite (graph background). So there is a tradeoff: I can either have (Case 1) a nice background and choppy lines/points, or I can have (Case 2) nice smooth lines/points and a degraded background. But obviously I need both. The Code: I have included code of the draw() method of the CCLayer for both cases explained above. As you can see, the code producing the difference between Case 1 and Case 2 seems to be 1 or 2 lines involving OpenGL Blending. Case 1 -- MainScene.h (CCLayer): -(void)draw{ int lastPointX = 0; int lastPointY = 0; GLfloat colorMAX = 255.0f; GLfloat valR; GLfloat valG; GLfloat valB; if([self.myGraphManager ready]){ valR = (255.0f/colorMAX)*1.0f; valG = (255.0f/colorMAX)*1.0f; valB = (255.0f/colorMAX)*1.0f; NSEnumerator *enumerator = [[self.myGraphManager.currentCanvas graphPoints] objectEnumerator]; GraphPoint* object; while ((object = [enumerator nextObject])) { if(object.filled){ /*Commenting out the following two lines induces a problem of making it impossible to have smooth lines/points, but has merit in that it does not degrade the background sprite.*/ //glEnable (GL_BLEND); //glBlendFunc (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glHint (GL_LINE_SMOOTH_HINT, GL_DONT_CARE); glEnable (GL_LINE_SMOOTH); glLineWidth(1.5f); glColor4f(valR, valG, valB, 1.0); ccDrawLine(ccp(lastPointX, lastPointY), ccp(object.position.x, object.position.y)); lastPointX = object.position.x; lastPointY = object.position.y; glPointSize(3.0f); glEnable(GL_POINT_SMOOTH); glHint(GL_POINT_SMOOTH_HINT, GL_NICEST); ccDrawPoint(ccp(lastPointX, lastPointY)); } } } } Case 2 -- MainScene.h (CCLayer): -(void)draw{ int lastPointX = 0; int lastPointY = 0; GLfloat colorMAX = 255.0f; GLfloat valR; GLfloat valG; GLfloat valB; if([self.myGraphManager ready]){ valR = (255.0f/colorMAX)*1.0f; valG = (255.0f/colorMAX)*1.0f; valB = (255.0f/colorMAX)*1.0f; NSEnumerator *enumerator = [[self.myGraphManager.currentCanvas graphPoints] objectEnumerator]; GraphPoint* object; while ((object = [enumerator nextObject])) { if(object.filled){ /*Enabling the following two lines gives nice smooth lines/points, but has a problem in that it degrades the background sprite.*/ glEnable (GL_BLEND); glBlendFunc (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glHint (GL_LINE_SMOOTH_HINT, GL_DONT_CARE); glEnable (GL_LINE_SMOOTH); glLineWidth(1.5f); glColor4f(valR, valG, valB, 1.0); ccDrawLine(ccp(lastPointX, lastPointY), ccp(object.position.x, object.position.y)); lastPointX = object.position.x; lastPointY = object.position.y; glPointSize(3.0f); glEnable(GL_POINT_SMOOTH); glHint(GL_POINT_SMOOTH_HINT, GL_NICEST); ccDrawPoint(ccp(lastPointX, lastPointY)); } } } }

  • Design pattern for parsing data that will be grouped to two different ways and flipped

    - by lewisblackfan
    I'm looking for an easily maintainable and extendable design model for a script to parse an excel workbook into two separate workbooks after pulling data from other locations like the command line, and a database. The high level details are as follows. I need to parse an excel workbook containing a sheet that lists unique question names, the only reliable information that can be parsed from the question name is the book code that identifies the title and edition of the textbook the question is associated with, the rest of the question name is not standardized well enough to be reliably parsed by computer. The general form of the question name is best described by the following regular expression. '^(\w+)\s(\w{1,2})\.(\w{1,2})\.(\w{1,3})\.(\w{1,3}\.)*$' The first sub-pattern is the book code, the second sub-pattern is 90% of the time the chapter, and the rest of the sub-patterns could be section, problem type, problem number, or question type information. There is no simple logic, at least not one I can find. There will be a minimum of three other columns in this spreadsheet; one column will be the chapter the question is associated with, the second will be the section within the chapter the question is associated with, and the third will be some kind of asset indicated by a uniform resource locator. 1 | 1 | qname1 | url | description | url | description ... 1 | 1 | qname2 | url | description 1 | 1 | qname3 | url | description | url | description | url | The asset can be indicated by a full or partial uniform resource locator, the partial url will need to be completed before it can be fed into the application. There theoretically could be no limit to the number of asset columns, the assets will be grouped in columns by type. Some times additional data will have to be retrieved from a database or combined with the book code before the asset url is complete and can be understood by the application that will be using the asset. The type is an abstraction, there are eight types right now, each with their own logic in how the uniform resource locator is handled and or completed, and I have to add a new type and its logic every three or four months. For each asset url there is the possibility of a description column, a character string for display in the application, but not always. (I've already worked out validating the description text, and squashing MSs obscure code page down to something 7-bit ascii can handle.) Now that all the details are filled-in I can get to the actual problem of parsing the file. I need to split the information in this excel workbook into two separate workbooks. The first workbook will group all the questions by section in rows. With the first cell being the section doublet and the rest of the cells in the row are the question names. 1.1 | qname1 | qname2 | qname3 | qname4 | 1.2 | qname1 | qname2 | qname3 | 1.3 | qname1 | qname2 | qname3 | qname4 | qname5 There is no set number of questions for each section as you can see from the above example. The second workbook is more complicated, there is one row per asset, and question names that have more than one asset will be duplicated. There will be four or five columns on this sheet. The first is the question name for the asset, the second is a media type used to select the correct icon for the asset in the application, the third is string representing the asset type, the four is the full and complete uniform resource locator for the asset, and the fifth columns is the optional text description for the asset. q1 | mtype1 | atype1 | url | description q1 | mtype2 | atype2 | url | description q1 | mtype2 | atype3 | url | description q2 | mtype1 | atype1 | url | description q2 | mtype2 | atype3 | url | description For the original six types I did have a script that parsed the source excel workbook into the other two excel workbooks, and I was able to add two more types until I ran aground on the implementation of the ninth type and tenth types. What broke my script was the fact that the ninth type is actually a sub-type of one of the original six, but with entirely different logic, and my mostly procedural script could not accommodate without duplicating a lot of code. I also had a lot of bugs in the script and will be writing the test first on this time around. I'm stuck with the format for the resulting two workbooks, this script is glue code, development went ahead with the project without bothering to get a complete spec from the sponsor. I work for the same company as the developers but in the editorial department, editorial is co-sponsor of the project, and am expected to fix pesky details like this (I'm foaming at the mouth as I type this). I've tried factories, I've tried different object models, but each resulting workbook is so different when I find a design that works for generating one workbook the code is not really usable for generating the other. What I would really like are ideas about a maintainable and extensible design for parsing the source workbook into both workbooks with maximum code reuse, and or sympathy.

Can some one please help me look at the code and what its outputs are? I tried engine.evaluate, but i do not know what is the QScriptValue i'm getting in return. Thanks sooo much. This is the script: BarChart.prototype = new QWidget; BarChart.prototype.suffix = ""; function BarChart(parent) { QWidget.call(this, parent); } // find the maximum value and widest (pixel-wise) label and suffix BarChart.prototype.showEvent = function(event) { var fm = new QFontMetrics(this); this.margin = 20; this.titleHeight = fm.height(); this.barHeight = 1.5 * fm.height(); this.barSpacing = 0.6 * fm.height(); this.maxValue = this.suffixWidth = this.labelWidth = 0; var count = 0; for (d in this.data) { this.labelWidth = Math.max(this.labelWidth, fm.width(d)); this.maxValue = Math.max(this.maxValue, this.data[d]); this.suffixWidth = Math.max(this.suffixWidth, fm.width(String(this.data[d]) + " " + this.suffix)); count++; } this.startHue = 15; this.hueDelta = 360 / count; this.size = new QSize(640, this.titleHeight + 2 * this.margin + (this.barHeight + this.barSpacing) * count); } BarChart.prototype.paintEvent = function(event) { var p = new QPainter; p.begin(this); // background and title p.fillRect(this.rect, new QBrush(new QColor(255, 255, 255))); p.drawText(0, 0, this.width, this.margin + this.titleHeight, Qt.AlignCenter, this.windowTitle, 0); var ofs = this.labelWidth + this.margin; var ww = this.width - this.suffixWidth - ofs - 2 * this.margin; var hue = this.startHue; var y = 0; p.translate(this.margin, this.titleHeight + 1.5 * this.margin); for (d in this.data) { // label on the left side p.setPen(new QColor(Qt.black)); p.drawText(0, y, this.labelWidth, this.barHeight, Qt.AlignVCenter + Qt.AlignRight, d, 0); // the colored bar var gradient = new QLinearGradient(new QPoint(ofs, y), new QPoint(ofs, y + this.barHeight)); gradient.setColorAt(0, QColor.fromHsv(hue, 255, 240)); gradient.setColorAt(1, QColor.fromHsv(hue, 255, 92)); p.setBrush(new QBrush(gradient)); p.setPen(new QColor(96, 96, 96)); var bw = this.data[d] * ww / this.maxValue; p.drawRect(ofs, y, bw, this.barHeight); // extra text at the end of the bar var text = new String(this.data[d] + " " + this.suffix); p.setPen(new QColor(Qt.black)); p.drawText(ofs + bw + this.margin/2, y, this.suffixWidth, this.barHeight, Qt.AlignVCenter + Qt.AlignLeft, text, 0); // for the next bar y += (this.barHeight + this.barSpacing); hue += this.hueDelta; if (hue >= 360) hue -= 360; } p.end(); } BarChart.prototype.wheelEvent = function(event) { this.startHue += event.delta() / 8 / 5; if (this.startHue = 360) this.startHue -= 360; if (this.startHue < 0) this.startHue += 360; this.update(); event.ignore(); } BarChart.prototype.mousePressEvent = function(event) { var fname = QFileDialog.getSaveFileName(this, "Save", ".", "*.png", 0, 0); if (fname.length > 0) { var img = new QImage(this.size, QImage.Format_ARGB32_Premultiplied); this.render(img); img.save(new QFile(fname)); } } var chart = new BarChart; chart.windowTitle = "Monthly"; chart.suffix = "reports"; chart.data = { "September" : 45, "October" : 60, "November" : 56, "December" : 0 }; chart.show(); QCoreApplication.exec();
