  • how to install software in a different location?

    - by studiohack
    When I am installing software, I usually like to choose where it installs to, other than C:/Program Files...However, from time to time, I come across software that does not let you choose the install location...how can I get around this and choose the install location? This is handy in situations such as multiple partitions or separate system and data partitions, etc... Any ideas? Thanks! (using Windows 7)

  • What is a 8086 relocatable?

    - by gerrit
    I'm running some Fortran software (LBLRTM) and a shell-script that prepares input generates a number of files with names TAPE3, TAPE4, etc. For debugging purposes, I used file to identify the file type. file tells me: TAPE3: 8086 relocatable (Microsoft) My guess is that file is wrong here, and that it's just a binary file that happens to look like a 8086 relocatable. But what is a 8086 relocatable?

  • Changing default install path in Windows 7

    - by brack
    I'm trying to change the default install path in Windows 7 Pro x64. I'm in the Registry Editor and in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion key. I know I need to change ProgramFilesDir and ProgramFilesDir (x86). What I'm not sure about is the CommonFilesDir, CommonFilesDir (x86) and the ProgramW6432Dir. Do I need to or should I change these values to reflect the new program files directory I'm using? I tried Googling ProgramW6432Dir and didn't get much help.

  • Chrome: Save as dialogue creates temp file in download directory, I want to change this location

    - by Gabardine
    I've set the download directory for Chrome to be my desktop, but that means that whenever I want to "Save As" it creates a temp file on my desktop until I select the final download destination and close the dialogue. This is deeply frustrating since I browse windowed and I keep seeing the damn things pop up and disappear in the corner of my eye, is there any way to change the directory in which temp files are created in this manner?

  • SWFUpload multiple files server-side handling

    - by Chau
    I need the user to be able to upload multiple files to my server, thus I am using the SWFUpload utility. SWFUpload sends the files one by one, and I need to store them all in the same temporary directory. My ASP.NET handler recieves the files one by one and I can store the file appropriately. My problem is: How do I know which files belong to the same upload? Rephrased, how do I connect the files in my handler?

  • Mercurial hook to disallow committing large binary files

    - by hekevintran
    I want to have a Mercurial hook that will run before committing a transaction that will abort the transaction if a binary file being committed is greater than 1 megabyte. I found the following code which works fine except for one problem. If my changeset involves removing a file, this hook will throw an exception. The hook (I'm using pretxncommit = python:checksize.newbinsize): from mercurial import context, util from mercurial.i18n import _ import mercurial.node as dpynode '''hooks to forbid adding binary file over a given size Ensure the PYTHONPATH is pointing where hg_checksize.py is and setup your repo .hg/hgrc like this: [hooks] pretxncommit = python:checksize.newbinsize pretxnchangegroup = python:checksize.newbinsize preoutgoing = python:checksize.nopull [limits] maxnewbinsize = 10240 ''' def newbinsize(ui, repo, node=None, **kwargs): '''forbid to add binary files over a given size''' forbid = False # default limit is 10 MB limit = int(ui.config('limits', 'maxnewbinsize', 10000000)) tip = context.changectx(repo, 'tip').rev() ctx = context.changectx(repo, node) for rev in range(ctx.rev(), tip+1): ctx = context.changectx(repo, rev) print ctx.files() for f in ctx.files(): fctx = ctx.filectx(f) filecontent = fctx.data() # check only for new files if not fctx.parents(): if len(filecontent) > limit and util.binary(filecontent): msg = 'new binary file %s of %s is too large: %ld > %ld\n' hname = dpynode.short(ctx.node()) ui.write(_(msg) % (f, hname, len(filecontent), limit)) forbid = True return forbid The exception: $ hg commit -m 'commit message' error: pretxncommit hook raised an exception: apps/helpers/templatetags/include_extends.py@bced6272d8f4: not found in manifest transaction abort! rollback completed abort: apps/helpers/templatetags/include_extends.py@bced6272d8f4: not found in manifest! I'm not familiar with writing Mercurial hooks, so I'm pretty confused about what's going on. Why does the hook care that a file was removed if hg already knows about it? Is there a way to fix this hook so that it works all the time? Update (solved): I modified the hook to filter out files that were removed in the changeset. def newbinsize(ui, repo, node=None, **kwargs): '''forbid to add binary files over a given size''' forbid = False # default limit is 10 MB limit = int(ui.config('limits', 'maxnewbinsize', 10000000)) ctx = repo[node] for rev in xrange(ctx.rev(), len(repo)): ctx = context.changectx(repo, rev) # do not check the size of files that have been removed # files that have been removed do not have filecontexts # to test for whether a file was removed, test for the existence of a filecontext filecontexts = list(ctx) def file_was_removed(f): """Returns True if the file was removed""" if f not in filecontexts: return True else: return False for f in itertools.ifilterfalse(file_was_removed, ctx.files()): fctx = ctx.filectx(f) filecontent = fctx.data() # check only for new files if not fctx.parents(): if len(filecontent) > limit and util.binary(filecontent): msg = 'new binary file %s of %s is too large: %ld > %ld\n' hname = dpynode.short(ctx.node()) ui.write(_(msg) % (f, hname, len(filecontent), limit)) forbid = True return forbid

  • Installing my sdist from PyPI puts the files in the wrong places

    - by Tartley
    Hey. My problem is that when I upload my Python package to PyPI, and then install it from there using pip, my app breaks because it installs my files into completely different locations than when I simply install the exact same package from a local sdist. Installing from the local sdist puts files on my system like this: /Python27/ Lib/ site-packages/ gloopy-0.1.alpha-py2.7.egg/ (egg and install info files) data/ (images and shader source) doc/ (html) examples/ (.py scripts that use the library) gloopy/ (source) This is much as I'd expect, and works fine (e.g. my source can find my data dir, because they lie next to each other, just like they do in development.) If I upload the same sdist to PyPI and then install it from there, using pip, then things look very different: /Python27/ data/ (images and shader source) doc/ (html) Lib/ site-packages/ gloopy-0.1.alpha-py2.7.egg/ (egg and install info files) gloopy/ (source files) examples/ (.py scripts that use the library) This doesn't work at all - my app can't find its data files, plus obviously it's a mess, polluting the top-level /python27 directory with all my junk. What am I doing wrong? How do I make the pip install behave like the local sdist install? Is that even what I should be trying to achieve? Details I have setuptools installed, and also distribute, and I'm calling distribute_setup.use_setuptools() WindowsXP, Python2.7. My development directory looks like this: /gloopy /data (image files and GLSL shader souce read at runtime) /doc (html files) /examples (some scripts to show off the library) /gloopy (the library itself) My MANIFEST.in mentions all the files I want to be included in the sdist, including everything in the data, examples and doc directories: recursive-include data *.* recursive-include examples *.py recursive-include doc/html *.html *.css *.js *.png include LICENSE.txt include TODO.txt My setup.py is quite verbose, but I guess the best thing is to include it here, right? I also includes duplicate references to the same data / doc / examples directories as are mentioned in the MANIFEST.in, because I understand this is required in order for these files to be copied from the sdist to the system during install. NAME = 'gloopy' VERSION= __import__(NAME).VERSION RELEASE = __import__(NAME).RELEASE SCRIPT = None CONSOLE = False def main(): import sys from pprint import pprint from setup_utils import distribute_setup from setup_utils.sdist_setup import get_sdist_config distribute_setup.use_setuptools() from setuptools import setup description, long_description = read_description() config = dict( name=name, version=version, description=description, long_description=long_description, keywords='', packages=find_packages(), data_files=[ ('examples', glob('examples/*.py')), ('data/shaders', glob('data/shaders/*.*')), ('doc', glob('doc/html/*.*')), ('doc/_images', glob('doc/html/_images/*.*')), ('doc/_modules', glob('doc/html/_modules/*.*')), ('doc/_modules/gloopy', glob('doc/html/_modules/gloopy/*.*')), ('doc/_modules/gloopy/geom', glob('doc/html/_modules/gloopy/geom/*.*')), ('doc/_modules/gloopy/move', glob('doc/html/_modules/gloopy/move/*.*')), ('doc/_modules/gloopy/shapes', glob('doc/html/_modules/gloopy/shapes/*.*')), ('doc/_modules/gloopy/util', glob('doc/html/_modules/gloopy/util/*.*')), ('doc/_modules/gloopy/view', glob('doc/html/_modules/gloopy/view/*.*')), ('doc/_static', glob('doc/html/_static/*.*')), ('doc/_api', glob('doc/html/_api/*.*')), ], classifiers=[ 'Development Status :: 1 - Planning', 'Intended Audience :: Developers', 'License :: OSI Approved :: BSD License', 'Operating System :: Microsoft :: Windows', 'Programming Language :: Python :: 2.7', ], # see classifiers http://pypi.python.org/pypi?:action=list_classifiers ) config.update(dict( author='Jonathan Hartley', author_email='[email protected]', url='http://bitbucket.org/tartley/gloopy', license='New BSD', ) ) if '--verbose' in sys.argv: pprint(config) setup(**config) if __name__ == '__main__': main()

  • Any way to cache WAV files in IE?

    - by Dan Howard
    I'm seeing an issue with our web application. We have a few wave files which we can play (like ding.wav) and we have attempted to pre-load wave files but using Fiddler we're seeing that the WAV files are never cached like (js and css and image files). We always see an HTTP 200 instead of an HTTP 304. Any ideas on how to tell IE that it should cache wav files? We're inserting a div: <EMBED SRC='ding.wav' AUTOSTART='FALSE' HIDDEN='TRUE'>

  • Java Logger API

    - by Koppar
    This is a more like a tip rather than technical write up and serves as a quick intro for newbies. The logger API helps to diagnose application level or JDK level issues at runtime. There are 7 levels which decide the detailing in logging (SEVERE, WARNING, INFO, CONFIG, FINE, FINER, FINEST). Its best to start with highest level and as we narrow down, use more detailed logging for a specific area. SEVERE is the highest and FINEST is the lowest. This may not make sense until we understand some jargon. The Logger class provides the ability to stream messages to an output stream in a format that can be controlled by the user. What this translates to is, I can create a logger with this simple invocation and use it add debug messages in my class: import java.util.logging.*; private static final Logger focusLog = Logger.getLogger("java.awt.focus.KeyboardFocusManager"); if (focusLog.isLoggable(Level.FINEST)) { focusLog.log(Level.FINEST, "Calling peer setCurrentFocusOwner}); LogManager acts like a book keeper and all the getLogger calls are forwarded to LogManager. The LogManager itself is a singleton class object which gets statically initialized on JVM start up. More on this later. If there is no existing logger with the given name, a new one is created. If there is one (and not yet GC’ed), then the existing Logger object is returned. By default, a root logger is created on JVM start up. All anonymous loggers are made as the children of the root logger. Named loggers have the hierarchy as per their name resolutions. Eg: java.awt.focus is the parent logger for java.awt.focus.KeyboardFocusManager etc. Before logging any message, the logger checks for the log level specified. If null is specified, the log level of the parent logger will be set. However, if the log level is off, no log messages would be written, irrespective of the parent’s log level. All the messages that are posted to the Logger are handled as a LogRecord object.i.e. FocusLog.log would create a new LogRecord object with the log level and message as its data members). The level of logging and thread number are also tracked. LogRecord is passed on to all the registered Handlers. Handler is basically a means to output the messages. The output may be redirected to either a log file or console or a network logging service. The Handler classes use the LogManager properties to set filters and formatters. During initialization or JVM start up, LogManager looks for logging.properties file in jre/lib and sets the properties if the file is provided. An alternate location for properties file can also be specified by setting java.util.logging.config.file system property. This can be set in Java Control Panel ? Java ? Runtime parameters as -Djava.util.logging.config.file = <mylogfile> or passed as a command line parameter java -Djava.util.logging.config.file = C:/Sunita/myLog The redirection of logging depends on what is specified rather registered as a handler with JVM in the properties file. java.util.logging.ConsoleHandler sends the output to system.err and java.util.logging.FileHandler sends the output to file. File name of the log file can also be specified. If you prefer XML format output, in the configuration file, set java.util.logging.FileHandler.formatter = java.util.logging.XMLFormatter and if you prefer simple text, set set java.util.logging.FileHandler.formatter =java.util.logging.SimpleFormatter Below is the default logging Configuration file: ############################################################ # Default Logging Configuration File # You can use a different file by specifying a filename # with the java.util.logging.config.file system property. # For example java -Djava.util.logging.config.file=myfile ############################################################ ############################################################ # Global properties ############################################################ # "handlers" specifies a comma separated list of log Handler # classes.

Just set the logger name to java.awt.focus.level=FINEST and change the default log level to FINEST. Below is a basic sample program. The sample programs are from http://www2.cs.uic.edu/~sloan/CLASSES/java/ and have been modified to illustrate the logging API. By changing the .level property in the logging.properties file, one can control the output written to the logs. To play around with the example, try changing the levels in the logging.properties file and notice the difference in messages going to the log file.

  • Signing redistributed files

    - by Garan
    In order to submit a desktop application for the Windows 8 app store, you need to digitally sign any driver or .exe associated with the application. However, the application I was trying to submit contains several files that are redistributions of other companies' software, and some of these are not signed. My application was rejected on these grounds. Is it legal (or ethical) to sign other companies' work so that we can submit our application? I think it might be considered some form of false representation but I'm not sure.

  • grubx64.efi cannot find grub config or grub files, boots to grub console

    - by endor43
    Sony VAIO with Insyde H2O EFI bios will not boot into GRUB EFI The answer to this question was immensely helpful to me and my new Vaio Z3. The issue that I am having now is that after replacing bootmgfw.efi with grubx64.efi and renaming, it boots directly to grub console. I dont even get a menu where i can chose ubuntu. I tried putting a grub.cfg file next to the new bootmgfw.efi(grubx64.efi), no go? Any ideas how i can get the renamed grubx64.efi to find all the rest of the grub stuff outside of the ESP in my linux parition? Or do i have to move all grub files to /EFI/Microsoft/Boot on ESP? Thank you!

  • Sending Big Files with WCF

    - by Sean Feldman
    I had to look into a project that submits large files to WCF service. Implementation is based on data chunking. This is a good approach when your client and server are not both based on WCF, bud different technologies. The problem with something like this is that chunking (either you wish it or not) complicates the overall solution. Alternative would be streaming. In WCF to WCF scenario, this is a piece of cake. When client is Java, it becomes a bit more challenging (has anyone implemented Java client streaming data to WCF service?). What I really liked about .NET implementation with WCF, is that sending header info along with stream was dead simple, and from the developer point of view looked like it’s all a part of the DTO passed into the service. [ServiceContract] public interface IFileUpload { [OperationContract] void UploadFile(SendFileMessage message); } Where SendFileMessage is [MessageContract] public class SendFileMessage { [MessageBodyMember(Order = 1)] public Stream FileData; [MessageHeader(MustUnderstand = true)] public FileTransferInfo FileTransferInfo; }

  • Commit in SQL

    - by PRajkumar
    SQL Transaction Control Language Commands (TCL)                                           (COMMIT) Commit Transaction As a SQL language we use transaction control language very frequently. Committing a transaction means making permanent the changes performed by the SQL statements within the transaction. A transaction is a sequence of SQL statements that Oracle Database treats as a single unit. This statement also erases all save points in the transaction and releases transaction locks. Oracle Database issues an implicit COMMIT before and after any data definition language (DDL) statement. Oracle recommends that you explicitly end every transaction in your application programs with a COMMIT or ROLLBACK statement, including the last transaction, before disconnecting from Oracle Database. If you do not explicitly commit the transaction and the program terminates abnormally, then the last uncommitted transaction is automatically rolled back.   Until you commit a transaction: ·         You can see any changes you have made during the transaction by querying the modified tables, but other users cannot see the changes. After you commit the transaction, the changes are visible to other users' statements that execute after the commit ·         You can roll back (undo) any changes made during the transaction with the ROLLBACK statement   Note: Most of the people think that when we type commit data or changes of what you have made has been written to data files, but this is wrong when you type commit it means that you are saying that your job has been completed and respective verification will be done by oracle engine that means it checks whether your transaction achieved consistency when it finds ok it sends a commit message to the user from log buffer but not from data buffer, so after writing data in log buffer it insists data buffer to write data in to data files, this is how it works.   Before a transaction that modifies data is committed, the following has occurred: ·         Oracle has generated undo information. The undo information contains the old data values changed by the SQL statements of the transaction ·         Oracle has generated redo log entries in the redo log buffer of the System Global Area (SGA). The redo log record contains the change to the data block and the change to the rollback block. These changes may go to disk before a transaction is committed ·         The changes have been made to the database buffers of the SGA. These changes may go to disk before a transaction is committed   Note:   The data changes for a committed transaction, stored in the database buffers of the SGA, are not necessarily written immediately to the data files by the database writer (DBWn) background process. This writing takes place when it is most efficient for the database to do so. It can happen before the transaction commits or, alternatively, it can happen some times after the transaction commits.   When a transaction is committed, the following occurs: 1.      The internal transaction table for the associated undo table space records that the transaction has committed, and the corresponding unique system change number (SCN) of the transaction is assigned and recorded in the table 2.      The log writer process (LGWR) writes redo log entries in the SGA's redo log buffers to the redo log file. It also writes the transaction's SCN to the redo log file. This atomic event constitutes the commit of the transaction 3.      Oracle releases locks held on rows and tables 4.      Oracle marks the transaction complete   Note:   The default behavior is for LGWR to write redo to the online redo log files synchronously and for transactions to wait for the redo to go to disk before returning a commit to the user. However, for lower transaction commit latency application developers can specify that redo be written asynchronously and that transaction do not need to wait for the redo to be on disk.   The syntax of Commit Statement is   COMMIT [WORK] [COMMENT ‘your comment’]; ·         WORK is optional. The WORK keyword is supported for compliance with standard SQL. The statements COMMIT and COMMIT WORK are equivalent. Examples Committing an Insert INSERT INTO table_name VALUES (val1, val2); COMMIT WORK; ·         COMMENT Comment is also optional. This clause is supported for backward compatibility. Oracle recommends that you used named transactions instead of commit comments. Specify a comment to be associated with the current transaction. The 'text' is a quoted literal of up to 255 bytes that Oracle Database stores in the data dictionary view DBA_2PC_PENDING along with the transaction ID if a distributed transaction becomes in doubt. This comment can help you diagnose the failure of a distributed transaction. Examples The following statement commits the current transaction and associates a comment with it: COMMIT     COMMENT 'In-doubt transaction Code 36, Call (415) 555-2637'; ·         WRITE Clause Use this clause to specify the priority with which the redo information generated by the commit operation is written to the redo log. This clause can improve performance by reducing latency, thus eliminating the wait for an I/O to the redo log. Use this clause to improve response time in environments with stringent response time requirements where the following conditions apply: The volume of update transactions is large, requiring that the redo log be written to disk frequently. The application can tolerate the loss of an asynchronously committed transaction. The latency contributed by waiting for the redo log write to occur contributes significantly to overall response time. You can specify the WAIT | NOWAIT and IMMEDIATE | BATCH clauses in any order. Examples To commit the same insert operation and instruct the database to buffer the change to the redo log, without initiating disk I/O, use the following COMMIT statement: COMMIT WRITE BATCH; Note: If you omit this clause, then the behavior of the commit operation is controlled by the COMMIT_WRITE initialization parameter, if it has been set. The default value of the parameter is the same as the default for this clause. Therefore, if the parameter has not been set and you omit this clause, then commit records are written to disk before control is returned to the user. WAIT | NOWAIT Use these clauses to specify when control returns to the user. The WAIT parameter ensures that the commit will return only after the corresponding redo is persistent in the online redo log. Whether in BATCH or IMMEDIATE mode, when the client receives a successful return from this COMMIT statement, the transaction has been committed to durable media. A crash occurring after a successful write to the log can prevent the success message from returning to the client. In this case the client cannot tell whether or not the transaction committed. The NOWAIT parameter causes the commit to return to the client whether or not the write to the redo log has completed. This behavior can increase transaction throughput. With the WAIT parameter, if the commit message is received, then you can be sure that no data has been lost. Caution: With NOWAIT, a crash occurring after the commit message is received, but before the redo log record(s) are written, can falsely indicate to a transaction that its changes are persistent. If you omit this clause, then the transaction commits with the WAIT behavior. IMMEDIATE | BATCH Use these clauses to specify when the redo is written to the log. The IMMEDIATE parameter causes the log writer process (LGWR) to write the transaction's redo information to the log. This operation option forces a disk I/O, so it can reduce transaction throughput. The BATCH parameter causes the redo to be buffered to the redo log, along with other concurrently executing transactions. When sufficient redo information is collected, a disk write of the redo log is initiated. This behavior is called "group commit", as redo for multiple transactions is written to the log in a single I/O operation. If you omit this clause, then the transaction commits with the IMMEDIATE behavior. ·         FORCE Clause Use this clause to manually commit an in-doubt distributed transaction or a corrupt transaction. ·         In a distributed database system, the FORCE string [, integer] clause lets you manually commit an in-doubt distributed transaction. The transaction is identified by the 'string' containing its local or global transaction ID. To find the IDs of such transactions, query the data dictionary view DBA_2PC_PENDING. You can use integer to specifically assign the transaction a system change number (SCN). If you omit integer, then the transaction is committed using the current SCN. ·         The FORCE CORRUPT_XID 'string' clause lets you manually commit a single corrupt transaction, where string is the ID of the corrupt transaction. Query the V$CORRUPT_XID_LIST data dictionary view to find the transaction IDs of corrupt transactions. You must have DBA privileges to view the V$CORRUPT_XID_LIST and to specify this clause. ·         Specify FORCE CORRUPT_XID_ALL to manually commit all corrupt transactions. You must have DBA privileges to specify this clause. Examples Forcing an in doubt transaction. Example The following statement manually commits a hypothetical in-doubt distributed transaction. Query the V$CORRUPT_XID_LIST data dictionary view to find the transaction IDs of corrupt transactions. You must have DBA privileges to view the V$CORRUPT_XID_LIST and to issue this statement. COMMIT FORCE '22.57.53';

  • SQL SERVER – Running Multiple Batch Files Together in Parallel

    - by pinaldave
    Recently I was preparing a demo for my next technical session, I had to do run a SQL code in parallel. I decided to use Batch File to run the code. I am not the best guy to with command shell so I did it with following setup. Code of tsql.sql SELECT 1 ColumnName Code of command.bat sqlcmd -S . -i tsql.sql timeout 100 Code of  AllBatch.bat start cmd.exe /C “command.bat” start cmd.exe /C “command.bat” start cmd.exe /C “command.bat” Now I ran AllBatch.bat and it run all the three files in parallel and simulated my needed scenario. I believe there should be simpler way using power-shell. Anybody want to come up with equivalent code which is improvement to this code?

  • Understanding Zabbix Triggers

    - by Mediocre Gopher
    I have zabbix set with an item to monitor a log file on a zabbix client: log["/var/log/program_name/client.log","ERROR:","UTF-8",100] And a trigger to determine when that log file get's more ERRORs: {Template_Linux:log["/var/log/program_name/client.log","ERROR:","UTF-8",100].change(0)}#0 This trigger gets tripped when the log file gets ERRORs the first time, but then that first trigger just sits around for ever in Monitoring-Triggers. My understanding is that the next time the server checks the value of log["/var/log/program_name/client.log","ERROR:","UTF-8",100] and sees that it hasn't changed that the trigger would go away. Obviously this isn't the case. Could someone explain why this first trigger isn't going away? Ultimately my goal is to receive an email whenever ERRORs are added to that log file, but I would like to understand how triggers are working first.

  • ODI 12c - Loading Files into Oracle, community post from ToadWorld

    - by David Allan
    There's a complete soup to nuts post from Deepak Vohra on the Oracle community pages of ToadWorld on loading a fixed length file into the Oracle database. This post is interesting from a few fronts; firstly this is the out of the box experience, no specialized KMs so just basic integration from getting the software installed to running a mapping. Also it demonstrates fixed length file integration including how to use the ODI UI to define the fields and pertinent properties.  Check the blog post out below.... http://www.toadworld.com/platforms/oracle/w/wiki/10935.loading-text-file-data-into-oracle-database-12c-with-oracle-data-integrator-12c.aspx Hopefully you also find this useful, many thanks to Deepak for sharing his experiences. You could take this example further and illustrate how to load into Oracle using the LKM File to Oracle via External table knowledge module which will perform much better and also leverage such things as using wildcards for loading many files into the 12c database.

  • Getting many files from a SharePoint Document Library the easy way

    - by Stacy Vicknair
    As an individual who does not use Internet Explorer as their primary browser, there is a great feature that you may never notice that allows you to easily copy files to and from a document library: the Open in Windows Explorer link. In browsers such as Chrome or Firefox this link may not appear. I know this isn’t a major groundbreaking feature, but it’s really easy to overlook and it’s worth knowing about, especially when you need to create a local copy of a full document library. In this quick blog we’ll go over how to access this feature in both SharePoint 2007 and 2010. First, make sure you are in Internet Explorer. These options may not show in other browsers. In SharePoint 2007, browse to the document library you would like to access then select Actions > Open with Windows Explorer. In SharePoint 2010, browse to the document library you would like to access then select Library Tools > Library > Open with Explorer from the ribbon.

  • How to get pngcrush to overwrite original files?

    - by DisgruntledGoat
    I've read through man pngcrush and it seems that there is no way to crush a PNG file and save it over the original. I want to compress several folders worth of PNGs so it would be useful to do it all with one command! Currently I am doing pngcrush -q -d . *.png then manually cut-pasting the files from the tmp directory to the original folder. So I guess using mv might be the best way to go? Any better ideas?

    I have VPS running Debian 5.0 (I think) and I would like to get it to run PHP files. I was told it needed to be configured with Apache.

How can I fix this?
