• How do I keep my Mac from constantly going to sleep?

  - by David

  The system is a PowerPC Mac Mini running MacOS Tiger 10.4.11. When I login (I'm the admin), everything seems fine - until about 10-15 minutes later. Then the system goes into sleep mode. Each time I try to wake the system up - I can barely log in before it goes to sleep again. Sometimes I don't have enough time to enter my password (from the screen saver). If I shut down and restart, then I have that 10-15 mins again - until it again goes to sleep. I checked the settings in the Displays and Energy System Prefs. I looked at Accounts and at Screen Saver System Prefs; no times seemed to be present. I've already reset the PROM and other things (as part of an earlier problem shooting session). If I don't log in at the desktop, things seem to be fine. Nothing in .profile, /etc/profile, or /etc/bashrc seems to stand out. Right now, the system is hardly usable; can someone help? Many thanks...

• Troubleshooting a Windows 7 PC that wouldn't sleep

  - by NPE

  I have a new Windows 7 PC that wouldn't sleep (not just automatically, but also when specifically told to). The screen goes black momentarily, but within two seconds the machine comes back as if nothing has happened. I tried powercfg energy. This produces some errors quoted at the bottom of this post, plus some warnings about timer resolution. There are no USB devices connected other than wireless keyboard + mouse (Logitech MK250); I tried unplugging them to no effect. The motherboard is Asus P7P55D-E. powercfg lastwake says "Wake History Count - 0", which I take to mean that it never actually went to sleep. I dual boot into Ubuntu, and was having exactly the same problem on the Linux side. That turned out to do with USB 3.0, which I've now disabled in the BIOS. This has solved the problem on the Ubuntu side of things, but made no difference to Windows 7. Any suggestions? Suspend:USB Device not Entering Suspend The USB device did not enter the Suspend state.

• PC shut downs automatically after 10-20 second. No POST screen, no beeps

  - by emzero

  I have this not-so-old computer that's not being used for a year or so. Specs: Motherboard: ASUS PN5-E SLI CPU: Intel Core2Duo E4300 RAM:2x2GB SuperTalent DDR2-800 VGA: Zogis GeForce 7950GT PSU: Vitsuba San-55-S 550w HD: No hardrives yet When I power on the computer, everything seem to start, but right away the whole system shuts down. I've removed and changed the RAM sticks, take out the VGA, everything I could think of. So what could it be causing this? The PSU? The motherboard is dead? The CPU? Any help to isolate the problem will be useful. Thanks PS: Please don't close the question, this could be helpful to anybody having a similar problem, even with different hardware. UPDATE I've removed the old thermal paste and apply a brand new one. I also cleaned every dust using a high pressure gas dust remover. Checked for bad capacitors, all of them seem ok. Opened the PSU, removed big giant dust balls, cleaned with high pressure dust remover. Still the same problem, but now it stays powered on for almost 20 seconds maybe. But no POST screen, no beeps at all, nothing. So I suspect it's a motherboard or PSU failure. Unfortunately I don't have an energy tester to test the PSU... Don't know what else to try. I don't have another 775-motherboard to test the CPU, RAM and VGA with it.

• Why does my PC successfully boot only when unplugged for more than a few minutes?

  - by philg

  I have an HP Pavilion Elite desktop computer, model HPE-490t. I like it because it didn’t cost too much, boots itself from an SSD, came with 16 GB of RAM, and has 6 CPU cores for editing video and camera RAW images. It has one behavioral quirk that I cannot explain, however. The recent power interruptions here in the Northeast got the machine into a state where it could not be restarted. It would power up for a second or two, shut down, and then power up again, never being able to get to the point of showing anything on the monitor. I unplugged it for about 10 seconds and plugged it back in. Same behavior (fails to boot). I unplugged it and walked away for an hour, then plugged it back in and it worked perfectly! I think something similar happened after installing a second hard disk drive into this machine. So the question is why does the computer behave differently depending on how long it has been unplugged? Where is energy stored that affects the machine’s ability to boot? Capacitors in the power supply? Battery on the motherboard (there is one for the clock, but that wouldn’t be exhausted by being unplugged for an hour, I don’t think)?

• Mac mini simple customized, Mac mini server or other?

  - by microspino

  I'm in front of a big IT choice for my little office and I need some advice. We have 5 users, 1 super user, 1 HP500 DesignJet Plotter, other 4 laser printers, 1 HP Fax/Print/Scan/Copy machine. All the clients are XP Sp3 boxes. We would like to: centralize and share 90Gb of files using a Dropbox (this way we will have LAN sync of local working directories + internet backup + access our files wherever we are). centralize our plotter, printers and fax machine backup all the workstations share outlook calendar and tasks run 24x7 saving some energy Of course this setup It's just the first step to a more serious and creative network management of our office, so we are open to new ideas. The budget vary from 400€ to 900€, we are not tech gurus but at least one of us is a power user close to become a geek. I've read some articles on macminicolo about a mac mini either normal or with snow leopard server. I heard about Windows Home Server too on the lifehacker website but I'm in a sort of analysis - paralysis can You help me?

• How far should we take the N+N redundancy craziness ?

  - by Brann

  The industry standard when it comes from redundancy is quite high, to say the least. To illustrate my point, here is my current setup (I'm running a financial service). Each server has a RAID array in case something goes wrong on one hard drive .... and in case something goes wrong on the server, it's mirrored by another spare identical server ... and both server cannot go down at the same time, because I've got redundant power, and redundant network connectivity, etc ... and my hosting center itself has dual electricity connections to two different energy providers, and redundant network connectivity, and redundant toilets in case the two security guards (sorry, four) needs to use it at the same time ... and in case something goes wrong anyway (a nuclear nuke? can't think of anything else), I've got another identical hosting facility in another country with the exact same setup. Cost of reputational damage if down = very high Probability of a hardware failure with my setup : <<1% Probability of a hardware failure with a less paranoiac setup : <<1% ASWELL Probability of a software failure in our application code : 1% (if your software is never down because of bugs, then I suggest you doublecheck your reporting/monitoring system is not down. Even SQLServer - which is arguably developed and tested by clever people with a strong methodology - is sometimes down) In other words, I feel like I could host a cheap laptop in my mother's flat, and the human/software problems would still be my higher risk. Of course, there are other things to take into consideration such as : scalability data security the clients expectations that you meet the industry standard But still, hosting two servers in two different data centers (without extra spare servers, nor doubled network equipment apart from the one provided by my hosting facility) would provide me with the scalability and the physical security I need. I feel like we're reaching a point where redundancy is just a communcation tool. Honestly, what's the difference between a 99.999% uptime and a 99.9999% uptime when you know you'll be down 1% of the time because of software bugs ? How far do you push your redundancy crazyness ?

• Why is MySQL table_cache full but never used

  - by Jeremy Clarke

  I have been using the tuning-primer.sh script to tune my my.cnf settings. I have most things working well but the part about TABLE CACHE makes no sense: TABLE CACHE Current table_cache value = 900 tables. You have a total of 0 tables You have 900 open tables. Current table_cache hit rate is 1% , while 100% of your table cache is in use. You should probably increase your table_cache When I do SHOW STATUS; I get the following table-related numbers: Open_tables = 900 Opened_tables = 0 It seems like something is going wrong. I have some extra memory I could use on increasing the table_cache size, but my sense is that the 900 tables already available aren't doing anything, and increasing it will just waste more energy. Why might this be happening? Are there other settings that could cause all my table_cache slots to be used even though there are no hits to them? I have 150 max connections and probably no more than 4 tables per join, FWIW. Here is the tuner script output for temp tables, which I've also been tuning: TEMP TABLES Current max_heap_table_size = 90 M Current tmp_table_size = 90 M Of 11032358 temp tables, 40% were created on disk Perhaps you should increase your tmp_table_size and/or max_heap_table_size to reduce the number of disk-based temporary tables. Note! BLOB and TEXT columns are not allow in memory tables. If you are using these columns raising these values might not impact your ratio of on disk temp tables.

• Ubuntu 10.10 - PC shutdown before boot shortly after BIOS loads

  - by clem

  Since installing Ubuntu 10.10 from Karmic I've started getting problems with starting up the PC. I've done a complete wipe (Boot and Nuke) of the hard drive and reinstalled Ubuntu 10.10 but the problem still occurs. There is no dual boot on the PC, just Ubuntu. Here is the problem: Each morning, when I turn the PC on from being off overnight, the PC starts up and loads the BIOS. I get the following message Verifying DMI Pool Data... K8 NPT Data Change...Update New Data to DMI!....... Then poof the computer shuts off. However, after switching the computer back on around 6 or 7 times after it's turned itself off, it will eventually boot up without any problem. Also, once up and running for a while, I can shutdown and restart the PC first time, without any issues. I have also noticed a problem with the USB mouse being recognised and once I finally get the computer booted up, I need to unplug and then plug the mouse back in to get it working. I've opened the PC up and checked the connections (cables, cards and memory) and it all seems fine. The main issue with troubleshooting this problem is I cannot test any suggestions or fixes until the next morning because once the computer is up and running it will remain so! I do not leave the computer on overnight to save energy. So.. Is this a hardware / boot software issue? This is a very odd problem and I have googled to no avail. Any suggestions?

• Wake on Demand for Apache server in OS X 10.8

  - by Gary

  Mac OS X Mountain Lion does not have a Web Sharing box in the Sharing system prefs menu. It is thoroughly discussed on the web that the Apache server is available, and that it can be turned on manually in the command line, or by using a convenient Prefs Pane. That works while the computer is awake. But, when my computer goes to sleep, the server stops working, even though Wake for Network Access is checked in the Energy Saver Pref Pane. From the discussion on Bonjour, I see that this problem probably results from the fact that Apache isn't registered with Bonjour. Does that sound likely? If not, please make some suggestions. The connection is via hard-wired ethernet. If registration with Bonjour is the problem, I'd like to know how to register it. You gave a nice description of dns-sd, and the command description says dns-sd -R Name Type Domain Port [TXT...] (Register a service)", but I don't know what to use for "Name" or "Type", or the format of the domain. I tried some dns-sd -B searches and found nothing I could use as a model, and it doesn't show up in Bonjour Browser. Any suggestions would be appreciated.

• Improve wireless performance

  - by djechelon

  Hello, I have a Trust Speedshare Turbo Pro router, which is running on channel 6. I found that the wireless signal (and network performance) dramatically drops from my PDA (I can barely attach to the network, even if I set the PDA's energy settings to maximum wireless performance) when I even exit my room, and I don't have shielded walls or something like that. I can't even stream a SD video from my desktop (connected via LAN) to my laptop using WiFi, while via LAN it works fine. I read that changing router's channel could improve performance due to interference reducing. I found that almost all wireless networks around here run on channels 6 and 11. I tried to go to my router's settings page to change channel, but I found that the combo box only allows me to select 6!! I'm not sure, but I may have been able in the past to change channel, though not to all of the available channels. A few minutes ago I tried a firmware upgrade, but it didn't solve my problem. My question is Is it possible that my router is someway locked to its channel? I bought it on my own, I didn't receive it from my ISP Apart from boosting the antenna power to the maximum (which, by the way, increases the EM radiation my and my family's bodies absorb 24/7 and is little more environment-unfriendly), do you have any tips on getting high quality transmission up to 5 metres from the antenna? Thank you

• realtek lan driver problem - win 7

  - by tango _123

  Hi, my new notebook (ACER TM 8371) with Win 7(x32) professional as OS, has strage behaviour with respect to LAN. when I plug or unplug my charger cable, or my notebook goes in stad-by, or just a do nothing, the netwrok connection is lost. All the energy savings functionbality have been in-activated. if i check the network adapter information, it says "a network cabel is unplugged or corrupted", but it is not true.....the cable is in and it is not corrupted (i tried several which works on other machines). if a tried to di-habilitate and hence re-habilitate, it allows di-habilitation and not to further re-habilitate (it says "no driver for the network card" are available). in some cases, also, the driver disappears (i cannot see it anylonger). if i restart the notebook, everything comes back to normality, but.....today in 3 hours i had to restart 6 times!!! can anyone help me? win 7 says the driver is the last one, so no need to update it. here are some techinical information aboiut network card and driver: Name [00000015] Realtek PCIe GBE Family Controller Adapter type Ethernet 802.3 Product type Realtek PCIe GBE Family Controller Installated YES ID device PNP PCI\VEN_10EC&DEV_8168&SUBSYS_02831025&REV_02\4&266E4C4F&0&00E2 last reset 20/11/2009 11:27 Index 15 Service name RTL8167 I/O Port 0x0000FF00-0x0000FFFF Memory address 0xE2500000-0xE2500FFF Memory address 0xE1400000-0xE140FFFF IRQ Channel IRQ 18 Driver c:\windows\system32\drivers\rt86win7.sys (7.3.522.2009, 164,00 KB (167.936 Byte), 28/08/2009 22:12)

• I can't connect to internet via lan cable because 2032 battery died and my bios bios info is now empty [closed]

  - by Rand Om Guy

  I have a compaq CQ61-112SL from about 5 years now... the main battery is almost dead, doesn't keep more then 10 minutes. anyway my problem is that my motherboard battery didn't have any more energy left a few days ago and since then I can't access internet through lan cable but only via wifi. I need cable though. I saw that on my BIOS setup page there were a bunch of parameters missing like serial number, UUID, product number and stuff like that. Also when I start the notebook it prints something like : No serial found. or something like that. I don't really know if the reason why my lan cable doesn't work is the empty BIOS but i assume that's it. If it's not please enlighten me. Or anyway tell me how to update the serial number and product number to the real ones (instead of the 0000000000000 that is now in my bios). I downloaded HP DMI which should make it possible to set these variables on the BIOS but i'm on Windows 8 64bit and the executable file that I need to open for my laptop model says it can't run on 64 bit.

• Fake demostration software for command line

  - by Joe

  I'm looking for some software that would be useful for giving demonstrations. I regularly have to show the effects of scrips ect to classes while talking about their effects, and equaly regularly I have finger trouble and have to rewrite various commands - wasting class time and general energy. I'd like to be able to record a sequence of commands in advance, and then play them back at the speed of my choosing. So I might have a file that containes the commands: echo "hello world!" ls ls -l ls -l | sort I'd like to be able to play these commands back by typing similar ones in. So I'd have a blinking command prompt and if I typed 'echo "hxxx' the command prompt would read home$echo "hell and if I typed any other letters the terminal would fill up with the remainder of the command until I press enter, when it executes the command. The point is that even if I screw up the command when typing it, the command that I'd prepared in advance would be executed. My question is - does similar software exist for giving demonstrations? or even, is this an easy thing to script up...? EDIT - two quick things first of all I'm on osx - but it would be nice to get a general solution for other people who arrive here from google. and second a lot of the comments/answers are concentrating on, in effect, making it fast and easy to enter long commands by means of hotkeys and the like. Actually I'd like it to at least look like I'm typing live - that's why I put in the bit about the one-to-one keymapping, but I don't think I explained that quite as well as I could have...

• What is making iTunes stop playing when my computer idles?

  - by OwenP

  I've got a rare weekend with nothing to do, so I'm getting some housework done. I have iTunes playing for some background noise. Every 20 minutes or so, it just stops playing; if I move the mouse it starts again. I'm on Windows 7 64-bit. My power settings have my monitor turning off at 10 minutes and hard drives at 20. Both sleep and hibernate are disabled. "Aha!", you say, "Clearly when the hard drive is turned off iTunes is stopping!" Not so. I fiddled with the settings and changed them to make the hard drive sleep in 5 minutes, and iTunes kept playing for the 7 minutes I watched it. I'm currently trying to see what happens if I set the hard drive to never turn off, but I'd prefer to leave it at 20 minutes to save minor amounts of energy. (Edit: I just set it to 240 minutes, and it stopped at 20 minutes. It seems tied to when the monitor turns off; that seems odd and I'm testing that now.) What other settings could be the culprit?

• Mysql Algorithm for Determining Closest Colour Match

  - by buggedcom

  I'm attempting to create a true mosaic application. At the moment I have one mosaic image, ie the one the mosaic is based on and about 4000 images from my iPhoto library that act as the image library. I have already done my research and analysed the mosaic image. I've converted it into 64x64 slices each of 8 pixels. I've calculated the average colour for each slice and assertain the r, g, b and brightness (Luminance (perceived option 1) = (0.299*R + 0.587*G + 0.114*B)) value. I have done the same for each of the image library photos. The mosaic slices table looks like so. slice_id, slice_image_id, slice_slice_id, slice_image_column, slice_image_row, slice_colour_hex, slice_rgb_red, slice_rgb_blue, slice_rgb_green, slice_rgb_brightness The image library table looks like so. upload_id, upload_file, upload_colour_hex, upload_rgb_red, upload_rgb_green, upload_rgb_blue, upload_rgb_brightness So basically I'm reading the image slices from the slices table into PHP and then pulling out the appropriate images from the library table based on the colour hexs. My trouble is that I've been on this too long and probably had too many energy drinks so am not concentrating properly, I can't figure out the way to pick out the nearest colour neighbor if the appropriate hex code doesn't exist. Any ideas on the perfect query? NB: I know pulling out the slices one by one is not ideal however the mosaic is only rebuilt periodically so a sudden burst in the mysql load doesn't really bother me, however if there us a way to pull the images out all at once that would also be a massive bonus.

• rails + sheevaplug = rails home development server and more

  - by microspino

  Hello I'd like to build a "Rails Brick" using a Sheevaplug from Marvell (O.S. is Ubuntu out of the box but You can install other distributions on It). It will be a home server and a silent, low cost (99$) low energy development machine. I'd like to add rails RVM, lot of gems, git-based heroku like deployment, passenger + nginx. This way I could have a portable server with a complete development environment and maybe I could find a hosting company where I can co-locate a grid of this devices or I can sell It as a simple little server for 10 or less users offices, with some centralized rails services (I think to a CMS, a BLOG, a WIKI, calendar or whatever this little jewel could afford). The usb port could make It a print server too or a UMTS link to the web via HUAWEI like usb UMTS keys. Can you give me some hint about: Is this project a crazy-close-to-failure idea? Why? which gem would You include? which rails open source app would you suggest? I have already an Excito Bubba Server at home, I saw the TonidoPlug so It came up in my mind to build something similiar but Rails based (Bubba is PHP based, TonidoPlug I don't know but It does not seems a Rails thing).

• SQL Server Bulk insert of CSV file with inconsistent quotes

  - by mattstuehler

  Is it possible to BULK INSERT (SQL Server) a CSV file in which the fields are only OCCASSIONALLY surrounded by quotes? Specifically, quotes only surround those fields that contain a ",". In other words, I have data that looks like this (the first row contain headers): id, company, rep, employees 729216,INGRAM MICRO INC.,"Stuart, Becky",523 729235,"GREAT PLAINS ENERGY, INC.","Nelson, Beena",114 721177,GEORGE WESTON BAKERIES INC,"Hogan, Meg",253 Because the quotes aren't consistent, I can't use '","' as a delimiter, and I don't know how to create a format file that accounts for this. I tried using ',' as a delimter and loading it into a temporary table where every column is a varchar, then using some kludgy processing to strip out the quotes, but that doesn't work either, because the fields that contain ',' are split into multiple columns. Unfortunately, I don't have the ability to manipulate the CSV file beforehand. Is this hopeless? Many thanks in advance for any advice. By the way, i saw this post SQL bulk import from csv, but in that case, EVERY field was consistently wrapped in quotes. So, in that case, he could use ',' as a delimiter, then strip out the quotes afterwards.

• My OpenCL kernel is slower on faster hardware.. But why?

  - by matdumsa

  Hi folks, As I was finishing coding my project for a multicore programming class I came up upon something really weird I wanted to discuss with you. We were asked to create any program that would show significant improvement in being programmed for a multi-core platform. I’ve decided to try and code something on the GPU to try out OpenCL. I’ve chosen the matrix convolution problem since I’m quite familiar with it (I’ve parallelized it before with open_mpi with great speedup for large images). So here it is, I select a large GIF file (2.5 MB) [2816X2112] and I run the sequential version (original code) and I get an average of 15.3 seconds. I then run the new OpenCL version I just wrote on my MBP integrated GeForce 9400M and I get timings of 1.26s in average.. So far so good, it’s a speedup of 12X!! But now I go in my energy saver panel to turn on the “Graphic Performance Mode” That mode turns off the GeForce 9400M and turns on the Geforce 9600M GT my system has. Apple says this card is twice as fast as the integrated one. Guess what, my timing using the kick-ass graphic card are 3.2 seconds in average… My 9600M GT seems to be more than two times slower than the 9400M.. For those of you that are OpenCL inclined, I copy all data to remote buffers before starting, so the actual computation doesn’t require roundtrip to main ram. Also, I let OpenCL determine the optimal local-worksize as I’ve read they’ve done a pretty good implementation at figuring that parameter out.. Anyone has a clue? edit: full source code with makefiles here http://www.mathieusavard.info/convolution.zip cd gimage make cd ../clconvolute make put a large input.gif in clconvolute and run it to see results

• Connect two client sockets

  - by Hernán Eche

  Good morning, let's say Java has two kind of sockets... server sockets "ServerSocket" client sockets or just "Socket" ////so Simple ! Imagine the situation of two processes: X Client <-- Y Server The server process Y : has a "ServerSocket", that is listening to a TCP port The client process X : send a connection request through a -client type- "Socket" X ////so Simple ! then the accept() method (in server Y) returns a new client type "Socket", when it occurs, great the two Sockets get "interconected", so the -client socket- in client process, is connected with the -client socket- in the server process then (reading/writing in socket X is like reading/writing in socket Y, and viceversa. ) TWO CLIENT SOCKETS GET INTERCONECTED!! ////so Simple ! BUT... (there is always a But..) What if I create the two CLIENT sockets in same process, and I want to get them "interconected" ? ////mmm Complex =(... even posible? Let's say how to have TWO CLIENT SOCKETS GET INTERCONECTED WITHOUT using an intermediate ServerSocket ? I 've solved it.. by creating two threads for continuously reading A and writing B, and other for reading B and writng A... but I think could be a better way..(or should!) (Those world-energy-consuming threads are not necessary with the client-server aproach) Any help or advice would be appreciated!! Thanks

  I have a remote form like this and a checkbox in it. When I select or deselect the checkbox I would like to 1 - set the value of a hidden field 2 - ajax submit this form to its designated url. I tried $('search_form').onsubmit(), but I get an error saying onsubmit is not a function. Using prototype. Whats the best way to do this? <form onsubmit="new Ajax.Request('/searches/search_set?stype=1', {asynchronous:true, evalScripts:true, parameters:Form.serialize(this)}); return false;" method="post" id="new_search" class="new_search" action="/searches/search_set?stype=1"><div style="margin: 0pt; padding: 0pt; display: inline;"><input type="hidden" value="3TWSyMsZXI0nltz7zHAxuj1KX=" name="authenticity_token"></div> <a onclick="setSubmit(this);" href="#" class="submit-link-button fg-button ui-state-default fg-button-icon-left ui-corner-all" id="search_submit"><span class="ui-icon ui-icon-search"></span>'Search'</a> </div> <input type="checkbox" value="Energy" onclick="refreshResults(this);" name="search[conditions][article_tag][0]" id="search_conditions_article_tag_0">

• How to suggest changes as a recently-hired employee ?

  - by ereOn

  Hi, I was recently hired in a big company (thousands of people, to give an idea of the size). They said they hired me because of my rigor and because I was, despite my youngness (i'm 25), experienced as a C/C++ programer. Now that I'm in, I can see that the whole system is old and often uses obsolete technologies. There is no naming convention (files, functions, variables, ...), they don't use Version Control, don't use exceptions or polymorphism and it seems like almost everybody lost his passion (some of them are only 30 years old). I'd like to suggest somes changes but i don't want to be "the new guy that wants to change everything just because he doesn't want to fit in". I tried to "fit in", but actually, It takes me one week to do what I would do in one afternoon, just because of the poor tools we're forced to use. A lot my collegues never look at the new "things" and techniques that people use nowadays. It's like they just given up. The situation is really frustrating. Have you ever been in a similar situation and, if so, what advices would you give me ? Is there a subtle way of changing things without becoming the black sheep here ? Or should I just give up my passion and energy as well ? Thank you.

• Getting content from PHP: Trouble with POST and query.

  - by vgm64

  Apologies for my longest question on SO ever. I'm trying to interface with a php frontend for a mysql database in ROOT (a CERN framework in C++ for high energy physics analysis). To start off with, I tried to get this php interface to play nice with wget and curl first because I'm more familiar with them. The following command works: wget --post-data "hostname=localhost:3306&un=joeuser&pw=psswd&myquery=show_spazio_databases;" http://some.host.edu/log/log_query_matlab.php The results are: database1 database2 That's good. If I leave out the --post-data then I get the result: Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'admin'@'localhost' (using password: NO) in /log/log_query_matlab.php on line 6 i'm dead! Access denied for user 'admin'@'localhost' (using password: NO) Warning: mysql_query() [function.mysql-query]: Access denied for user 'admin'@'localhost' (using password: NO) in /log/log_query_matlab.php on line 29 Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /log/log_query_matlab.php on line 29 I have access to the php script (read only), but the error itself isn't too important. What matters it that using ROOT, I use a function called as socket.SendRaw(message, message.Length()) (socket is a TSocket) and this gives me the same "error" as wget without the post data switch if my "message" is "POST http://some.host.edu/log/log_query_matlab.php?hostname=localhost:3306&un=joeuser&pw=psswd&myquery=show_spazio_databases" This may be in vain, but does someone knows a way I should format the "message" that includes something that is equivalent to the --post-data switch. Or, is there a standard way to format POST requests in a single line (I've seen multi-line stuff. Is that right?) Sorry I'm clueless! PS. The mysql query is show databases but the space has been replaced with _spazio_, Italian for space. The author of the db and php interface requires it (and various replacements for symbols), but has anyone seen this before? Trying to troubleshoot that was terrible!

• NHibernate Session DI from StructureMap in components

  - by Corey Coogan

  I know this is somewhat of a dead horse, but I'm not finding a satisfactory answer. First let me say, I am NOT dealing with a web app, otherwise managing NH Session is quite simple. I have a bunch of enterprise components. Those components have their own service layer that will act on multiple repositories. For example: Claim Component Claim Processing Service Claim Repository Billing Component Billing Service Billing REpository Policy Component PolicyLockService Policy Repository Now I may have a console, or windows application that needs to coordinate an operation that involves each of the services. I want to write the services to be injected with (DI) their required repositories. The Repositories should have an ISession, or similar, injected into them so that I can have this operation performed under one ISession/ITransaction. I'm aware of the Unit Of Work pattern and the many samples out there, but none of them showed DI. I'm also leery of [ThreadStatic] because this stuff can also be used from WCF and I have found enough posts describing how to do that. I've read about Business Conversations, but need something simple that each windows/console app can easily bootstrap since we have alot of these apps and some pretty inexperienced developers. So how can I configure StructureMap to inject the same ISession into each of the dependent repositories from an application? Here's a totally contrived and totally made up example without using SM (for clarification only - please don't spend energy critisizing): ConsoleApplication Main { using(ISession session = GetSession()) using(ITransaction trans = session.BeginTransaction()) { var policyRepo = new PolicyRepo(session); var policyService = new PolicyService(policyRepo); var billingRepo = new BillingRepo(session) var billingService = new BillingService(billingRepo); var claimRepo = new ClaimsRepo(session); var claimService = new ClaimService(claimRepo, policyService, billingService); claimService.FileCLaim(); trans.Commit(); } }
