• How can I read PDFs with e-reader on a Lenovo tablet?

  - by Jack M

  This is my first time using a tablet and I'm totally lost - this must be what computers look like to old people. This is a Lenovo Thinkpad tablet. I don't see a specific model number on it (it was passed down to me second hand). What I'd like to do is read a PDF. I'm fairly certain I successfully transferred the PDF onto the tablet via an SD card, and I noticed this thing has an app called "eReader" on it, so I started that up. All I see are empty bookshelves, and no obvious buttons or settings anywhere. I saw in multiple places that you have to, as one site puts it: ...copy and paste the relevant files into the eBooks folder and they will appear on the eReader shelf for your consumption... But I have no idea how to: Access the file system. Locate the eBooks folder. Copy and paste files. Will I need a file explorer app? If so, how can I install that given that my only method of getting data onto this tablet is an SD card (no wireless internet).

• iTunes copy just metadata (song and album ratings, playlists) from iPod

  - by Jared Updike

  I have an iPod touch that I synched with my Windows computer (iTunes 9.0 I think) until my harddrive failed and I lost my entire library. I rebuilt the library (songs) from a year old backup (and various other source for songs) but my playlists and ratings are of course a year old. My iPod itself has most of the playlists and ratings I care most about (favorite songs and albums, rated 4 and 5, for example). I have a catch 22 situation where I feel nervous that I haven't backed up my iPod in around 4 months (when my drive failed) so I'd like to back it up as soon as possible... but if I back it up I have to clear all the songs and playlists and copy them back, which I can't really do since I need to rebuild my playlists on my computer first (using the data only available on my iPod!) The question: is there a better way to READ the information off my iPod than doing it manually, song by song and album by album and playlist by playlist (XML, text dump, database, spreadsheet, anything). In other words, mostly I want the information (metadata like ratings and playlists, not songs) copied off the iPod so I can more quickly get my iTunes library ratings and playlists re-built (manually) so I can finally wipe the music and back up my apps, etc. Then I'd like to copy the music back immediately. The part I'd like to avoid is manually navigating everything on my iPod to read through all the playlists and ratings (50 GB, 6,000+ songs) as I re-enter all of that data by hand. I've done a few dozen albums and it's pretty time consuming having to tap around on the iPod. Reading from a spreadsheet (for example, or XML which I could write a script to get into spreadsheet form) would probably help tremendously, plus then I'd have a backup of that information somewhere besides just my iPod.

• I need a driver for my Cardbus USB 2.0 card

  - by Carl

  The picture and details of the card are here: http://www.ht-link.com/en/ProductView.asp?ID=106 The Windows drivers for this don't work right. I tried them on my previous laptop, and then installed the ones off their included CD. (Note that the systems requirements includes a CD-ROM drive...) I have a new laptop, and lost the CD. The website that lists the drivers is broken - the download links don't work. It is here: http://www.ht-link.com/en/DownView.asp?ID=10 I need the very first link - The Win XP drivers for the HT-112NEC. The company does not reply to my e-mails. I've tried searching Google for other sources for the driver (I didn't bother with those sites that want me to install driver detection software or create a log-in for their site). [Here's the problem I am getting using the drivers Windows XP SP3 installs: When I plug in my USB 2.0 hard-disk adapter, a USB Mass Storage Device entry is added in the Device Manager, but there is no entry under Disk Drives, and a drive letter is not assigned, so I can't access the driver. Like I said, this card didn't work without their special drivers on my other laptop, either.]

• How to recover deleted files on ext3 fs

  - by Mike

  I have a drive which was using the ext3 filesystem. I am told that about 10Gb of data was deleted off the drive (probably via rm). The drive is currently mounted as read-only to preserve all data. Does anyone know of a method to restore some or all of the data? Also if it helps, the OS was Fedora. I've also been told that the data is mostly ASCII fortan source code and Matlab files. Conclusion I have finally managed to get the data back, and with the simplest means ever! After weeks of trying and failing to bring back much of any data, I brought someone in today to take a look at it and offer suggestions, he simply cd'd to the directory and everything was there! It was never lost in the first place!!! Needless to say I feel really dumb right now, but I learned quite a lot with this whole fiasco. At any rate, while I was looking through data forensics solutions, I found that the Autopsy, or more specifically the SleuthKit was the most helpful. So I will accept that as the final answer. I would also like to note for anyone that comes across this later on that the most up-voted (currently) answer by sekenre was also helpful and I learned a lot, but ultimately it did not help with the type (very many, and some being very large) of files I was dealing with. So thank to all you that provided suggestions and wish you all the best!

• disk space keeps filling up on EC2 instance with no apperent files/directories

  - by sasher

  How come os shows 6.5G used but I see only 3.6G in files/directories? Running as root on an Amazon Linux AMI (seems like Centos), lots of free memory available, no swapping going on, no apparent file descriptors issue. The only thing I can think of is a log file that was deleted while applications append to it. Disk space usage is slowly but continuously rising towards full capacity (~1k/min with very small decreases from time to time) Any explanation?

• 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)

• few basic questions on webhosting (namservers & dns records)

  - by claws

  I bought a domain name on name.com & I want to use free webhosting on 110mb.com By default name.com integrates services of Google apps. Name server entries are ns1.name.com ns2.name.com ns3.name.com ns4.name.com When I registered on 110mb.com it gave me two addresses ns1.110mb.com ns2.110mb.com This is where I'm lost. The concept is that "Domain name should point to an address of the server where the website is hosted" right? Then why are these 4 entires by default. How exactly is it working? should I remove these 4 and then add 110mb.com servers or just append 110mb.com server addresses to name.com ones. I would like to use google apps. If I change these name server addresses would that remove google apps? I especially want to use email service of google. And I really don't understand what is CNAME, MX, or something something. I want to learn about these stuff & how it exactly works. When I search for webhost tutorial. I'm unable to find any fruitful results.

• Low-traffic WordPress website on Apache keeps crashing server

  - by OC2PS

  I have recently moved my low-moderate traffic (1000 UAUs, 5000 pageviews on a busy day) website from shared hosting to a Centos 6 64-bit VPS with Apache and cPanel running on 4 quad-core processor (likely oversold) and 3GB memory (Xen). We've had problems from the beginning. The server keeps crashing. It seems PHP keeps expanding till it consumes all the memory and crashes the server. Some folks have suggested that I should abandon Apache/cPanel/PHP/mySQL and go with nginX/Varnish/PHP-FPM/SQLite. But that's just not possible for me as I am not very tech savvy and need a simple GUI like cPanel to be able to manage the mundane management tasks (can't afford to hire system administrator or get fully managed hosting). I have come across several posts discussing optimization of Apache for WordPress. But all of these lead to articles that are pretty dated such as this ~4 year old one from Jan 2009 - http://thethemefoundry.com/blog/optimize-apache-wordpress/ The article is pretty detailed and seems helpful, but I stumble even on the first step. My httpd.conf only has 2 loadmodule commands LoadModule fastinclude_module modules/mod_fastinclude.so LoadModule bwlimited_module modules/mod_bwlimited.so So I go total bust right there. Further, my httpd.conf says Direct modifications to the Apache configuration file may be lost upon subsequent regeneration of the configuration file. To have modifications retained, all modifications must be checked into the configuration system by running: /usr/local/cpanel/bin/apache_conf_distiller I am having trouble finding where to change the modules in WHM. Please can someone help me with updated guidelines on how to optimize Apache for WordPress? Many thanks! P.S. The WordPress installation also has WP Super Cache installed. P.P.S. I also have phpBB, OpenCart, and Menalto Gallery installed.

• How to setup RAID 1 with Intel RST on an existing Windows 7 system?

  - by instcode

  I'd like to setup RAID-1 using Intel Rapid Storage Technology on my Windows 7 64-bit system. I have an 1TB SATA HDD with Windows 7 system installed on the first primary partition (leftmost, ~200GB). The rest of this HDD is unallocated (~800GB). I bought another 2TB SATA, then created a primary partition (leftmost, ~500GB) and filled my data in. The rest of this HDD is unallocated (~1.5TB). A quick disk layout (XXX is the unallocated region): HDD1 (1TB): [ 200GB C:\ SYSTEM | XXXXXXXXXXXX ] HDD2 (2TB): [ 500GB Z:\ PROGRAM | XXXXXXXXXXXXXXXXXXXXXX ] Now, I want to create a 500GB RAID-1 partition (I'm not sure if using "partition" is correct here) on the rightmost of the 2 HDDs above without losing any existing data from both disks. Here is the expected layout: HDD1 (1TB): [ 200GB C:\ SYSTEM | XXXXXX | 500GB D:\ DATA - RAID-1 ] HDD2 (2TB): [ 500GB Z:\ PROGRAM | XXXXXXXXXXXXXXXX | 500GB D:\ DATA RAID-1] Let's not concern about data lost, is it possible to have that final layout using Intel RST? Previously, I tried this layout using dynamic disk & software RAID from Windows and it worked as expected, however, it's quite ugly in resynching after an OS failure that I don't want. If yes, is there a way to keep the data on existing partitions untouched or, at least, it should keep the SYSTEM partition safe (I'm okay if the PROGRAM partition has to be gone.)? Well, are there any strict/special steps I should follow when using the Intel RST manager in order to achieve that? If none of those questions above are "Yes", could you please suggest some other possible layouts that leave the C:SYSTEM partition untouched?

• Linux Software RAID1: How to boot after (physically) removing /dev/sda? (LVM, mdadm, Grub2)

  - by flight

  A server set up with Debian 6.0/squeeze. During the squeeze installation, I configured the two 500GB SATA disks (/dev/sda and /dev/sdb) as a RAID1 (managed with mdadm). The RAID keeps a 500 GB LVM volume group (vg0). In the volume group, there's a single logical volume (lv0). vg0-lv0 is formatted with extfs3 and mounted as root partition (no dedicated /boot partition). The system boots using GRUB2. In normal use, the systems boots fine. Also, when I tried and removed the second SATA drive (/dev/sdb) after a shutdown, the system came up without problem, and after reconnecting the drive, I was able to --re-add /dev/sdb1 to the RAID array. But: After removing the first SATA drive (/dev/sda), the system won't boot any more! A GRUB welcome message shows up for a second, then the system reboots. I tried to install GRUB2 manually on /dev/sdb ("grub-install /dev/sdb"), but that doesn't help. Appearently squeeze fails to set up GRUB2 to launch from the second disk when the first disk is removed, which seems to be quite an essential feature when running this kind of Software RAID1, isn't it? At the moment, I'm lost whether this is a problem with GRUB2, with LVM or with the RAID setup. Any hints?

• Ubuntu 10.10 - disaster - what other linux for beginner?

  - by A-ha

  Guys, I've tried to install ubuntu (desktop and notebook ed) on my laptop and unortunately I have to say that as despite the fact that installation process supposed to be easy I couldn't finish installation of this system - didn't detect my keyboard or rather lost my keyboard as soon as I tried to switch on/off pad on my laptop. After I've discovered that, I started all over again (this time without touching my laptop's pad during installation) and yes, eventually it get to the end of installation. Unfortunately, when I've tried to switch my pad (sometimes I just do not want to use a mouse) the whole system froze. So I had to restart it with the power button and this time I didn't touch pad at all, plugged in mouse and tried to rearrange taskbars according to my liking (all taskbars on the top side of the screen and auto-hide on) and I gave up. It is so unfinished that I just can't be bothered to use it. I would like to have one linux system on my machine so I started googling and most of the links are to either ubuntu (which I just do not want to touch for now) and suse or commercial versions of linux. I do not really mind paying for something (and having experience with ubuntu I'd rather pay and have something pro then get it free and discover that it's unusable). So could someone please provide short list of linux distros which would be appropriate for a beginner, and I don't mind paying for it, I just want it to be a professional product.

• Redmine does not return the web page

  I migrated a Redmine installation from an Ubuntu machine to a Debian one (both 32-bits), and now for some reason, for some users it doesn't return the page but only a 200 OK message.

• How to "drag and drop" folders or multiple HTML files into a browser and have them open in multiple tabs

  - by PoorLuzer

  I save pages that I browse on the net and find interesting into a folder called C:\PageSaves Later, during the commute, I open these pages to see what they are and move them into a neatly categorized folder tree. For example, Perl related pages goto C:\Pages\Perl, MySQL related pages goto C:\Pages\MySQL and so on. I was wondering if there is any way I could open any number of HTML files on disc / inside a folder (C:\PageSaves in my case) into Mozilla/FF/K-Meleon etc For example, I would like to just "drag and drop" the folder C:\PageSaves into FireFox and have it open all the .html pages in the folder in a separate tab Right now, if I "drag and drop" multiple HTML files, it just opens the last file in the selection. Have a set of toolbar buttons, basically, a (the) plugin that should allow me to nuke the page (if I don't want to keep the page anymore) from disc or move the file (and its corresponding folder) into a predefined / new folder I am familiar with coding full blown FireFox plugins, so even if something very basic/almost similar exists, I can take it forward. Hints/clues/other methods of achieving the same result are all welcome!

• Is it possible to record a screen-video from a VNC server?

  - by nikie

  I have a computer that's running VNC server. I would like to record a video of what's going on on this computer, if possible without installing additional software on that computer. Is there a program that can connect to the VNC server port and instead of displaying the screen save it to an (e.g. AVI) video file? Background: One of our customers sometimes has problems with the software he bought from us when he's performing a complex procedure. To help him, we offered that someone (a service technician or programmer) watches what he's doing during that procedure to find out if he's doing something wrong or if there's a bug in the software. Currently, this is done live via VNC. That has a few disadvantages: The service technician has to be in the office at the time. As the customers are in different time zones, that can be in the middle of the night. If the service technician forgets something or doesn't notice something, it's lost. There's no way to see what happened again. Only a single computer can be watched by one service technician at a time. I know I could install normal screen-grab software on the computer, but we're talking about an embedded system with limited RAM, CPU, HDD space, so installing something new is not an easy decision. And VNC is already there. I could of course open a VNC client on some office PC and capture that PC's screen, but I can only record one remote computer that way. I often have to watch up to 8 screens in parallel. (And I don't think that screen-grabbing VNC would improve image quality, either.)

• ms excel 2010 in windows xp - when open workbook the data is formatted differently than when i saved it

  - by Justin

  I haven't been able to find an answer to this. I have multiple files that I use regularly in excel that now have cell formats of "date". Every single cell in the entire workbook (all sheets) is now formatted as "date". The problem is that I lost my formatting for percents, numbers years, etc and now everything is converted to date (xx/xx/xxxx). I am able to open previously saved versions of a file (prior to me having the problem) and the cells are formatted as I intend them to be (percents, numbers, general, as well as dates). Since this has happened on a couple different files recently, I am wondering how this is happening and how do I prevent it from happening in the future. I cannot cure the problem just by highlighting the entire sheet and converting back to general because I lose all my percents and number formatting. Example (Correct formatting): Month Year Working Days MTD POS Curr Rem May 2012 22 0 1,553,549 June 2012 22 0 1,516,903 June 2011 22 0 1,555,512 June 2010 22 0 1,584,704 Example (Incorrect formatting): Month Year Working Days MTD POS Curr Rem June Tuesday, July 04, 1905 Wednesday, January 04, 1900 Wednesday, January 18, 1900 213,320 July Tuesday, July 04, 1905 Wednesday, January 04, 1900 Monday, January 16, 1900 314,261 July Monday, July 03, 1905 Wednesday, January 04, 1900 Sunday, January 15, 1900 447,759 July Sunday, July 02, 1905 Wednesday, January 04, 1900 Monday, January 16, 1900 321,952 Sorry for the mess.

• hosting company blocking google bots and crawlers [closed]

  - by Jayapal Chandran

  Hi, I am having a site for the past three years and it is very active for the past two years. Until not the site is working well and also now but not after the hosting company blocked google bots. Many pages appeared in the first page of the google search. After they started blocking i couldn't see my links in the first page instead they appeared after 5 pages or they did not appear at all. Will hosting companies be so stupid that they block and dont mention it to their users. They want to protect themselves by making the websites at stake. I display google ads and not this month i got only half for this 10 days. I have made requests to other hosting companies like blue host and monster host that i wan to transfer my domain by making a condition that the will not block google bots which stops the business indirectly. so any kind of help will be helpful. how can i claim what i lost from the hosting company. what other hosting companies consider the users (by informing the events like changing the IP or blocking google bot.) It was really working hard to bring up my site but these people just crashed down my site in a few days. :-(

• Windows 7 Explorer: how to show total size of all files in current folder?

  - by matt wilkie

  In Windows XP Explorer one can turn on Status Bar which shows, among other things, the total size of all the files in the current folder, or if the cumulative size of the selected files. How do I get the same at-a-glance information in Windows 7? Selecting files doesn't count as it stops after 15 files, and it's rare that I'm concerned about total size with that few files (it's pretty easy to estimate in my head). thanks. UPDATE: Information derived from the context menu (select r-click properties) isn't "at a glance", and not as smooth as selecting files and clicking the details link at the bottom in any case. Thank you for fleshing out more of the available routes though. Yes Q19232 is similar to this one, though it is not a duplicate. That question is about looking for easy free-space on disk stats and this one is easy used-space by contents of this folder stats. The answer for both is the same though. You can't! Hopefully someone will figure how to get this lost feature back with a shell extension or something.

• Server side url scanner for malware, spyware , viruses and protect my visitors

  - by Vangel

  I have a forum/groups site that contains a lot of external URLs, sometimes direct download links. I want to protect my visitors from possible attacks from malware sites as they are mot likely to click on these links. CUrrently I implement DBL (spamhaus) but thats not enough. I want to run a background task to check the outgoing links first. I have looked at similar questions in StackOverflow (wrongly posted there) and here but fail to find a question same as mine or a good answer. People have suggested ClamAV , I don't believe it can detect Web hosted malware sites and its has a lot of missed detection. I have looked at google safe browsing service ( http://code.google.com/apis/safebrowsing/developers_guide_v2.html very complicated to implement or maintain plus midway I get lost :S ) I can go for commercial solution, anything to protect the visitors and my site brand. But I would like to hear the opinion of server admins and if anyone has implemented such a service. My Server is basic CentOS LAMP stack. thank you very much in advance.

• Restoring MBR, partition table, and boot sector of memory card without data loss ("USBC")

  - by Synetech

  Abstract I have a FAT32 memory card that when inserted into a computer causes Windows to prompt to format it. The card is definitely not supposed to be blank and has a bunch of files on it. Symptoms Using a hex-editor/disk-viewer, I examined the card and found that several sectors/clusters have been overwritten with something that has a signature of USBC at the start of the sector. Specifically, the master boot record (and partition table) is gone (hence Windows thinking the card is blank and needing to be formatted), as are the boot sectors (they have the USBC signature and a volume label of NO NAME and partition type of FAT32). Fortunately, it looks like both copies of the FAT are almost entirely intact (a few FAT entries at the start of a cluster here and there seem to be overwritten by USBC). The root directory is also nearly intact—I can see the volume label entry and subdirectory listings, but one sector is overwritten. (There are no more instances of USBC after the last one in the FAT2.) Hypothesis These observations seem to indicate some sort of virus that erases a few key filesystem structures, and then overwrites a few extra sectors here and there. Googling it seems to corroborate the idea of a virus, except that others report a file called USBC which does not apply here, and in fact, could not be possible since there is no filesystem to even see files. I cannot find any information about a virus with these symptoms, nor a removal tool. (I can't help but wonder if it is actually due to an autorun virus prevention tool.) Question I can likely fix the FAT corruption since they are mostly contiguous chains and maybe even the lost sector of the root directory, but does anyone know of a convenient way to restore or (re)create the MBR/partition table and boot sectors (without formatting or overwriting the data)?

• Alternative method of viewing a database diagram in SQL Server to see what tables have gone missing?

  - by Triynko

  I have a database diagram for my database, but when I open it in SQL Server, I almost immediately get a message saying some permissions changed or tables in the diagram were dropped or renamed, and tables in the diagram vanish before I can even scroll over to see what or where they were. Basically, it's saying, "Hey, you know all that time you spent laying out tables in this diagram... half of them are going to vanish when you view it, and I'm not going to tell you which tables vanished or where they were in the diagram. You're just going to see a bunch of random empty spaces where tables used to be ;)" Ridiculous. So I thought that maybe if I look in the dbo.sysdiagrams table, I could look at some plain text definition of the diagram to get a clue about the names of the tables that went missing (because thier names were probably only changed slightly) or their coordinates in the diagram (because their spatial location would give me a clue as to what they were), so that I could re-add them, but I can't, because it's a binary definition. So, is there some other program I could use to view the existing database diagram that's not going to just drop and forget the missing tables without telling me what they were, or is this information lost and at the mercy of some SSMS-proprietary database diagram format and viewer which refuses to cooperate with me.

• Linux iptables / conntrack performance issue

  - by tim

  I have a test-setup in the lab with 4 machines: 2 old P4 machines (t1, t2) 1 Xeon 5420 DP 2.5 GHz 8 GB RAM (t3) Intel e1000 1 Xeon 5420 DP 2.5 GHz 8 GB RAM (t4) Intel e1000 to test linux firewall performance since we got bitten by a number of syn-flood attacks in the last months. All machines run Ubuntu 12.04 64bit. t1, t2, t3 are interconnected through an 1GB/s switch, t4 is connected to t3 via an extra interface. So t3 simulates the firewall, t4 is the target, t1,t2 play the attackers generating a packetstorm thorugh (192.168.4.199 is t4): hping3 -I eth1 --rand-source --syn --flood 192.168.4.199 -p 80 t4 drops all incoming packets to avoid confusion with gateways, performance issues of t4 etc. I watch the packet stats in iptraf. I have configured the firewall (t3) as follows: stock 3.2.0-31-generic #50-Ubuntu SMP kernel rhash_entries=33554432 as kernel parameter sysctl as follows: net.ipv4.ip_forward = 1 net.ipv4.route.gc_elasticity = 2 net.ipv4.route.gc_timeout = 1 net.ipv4.route.gc_interval = 5 net.ipv4.route.gc_min_interval_ms = 500 net.ipv4.route.gc_thresh = 2000000 net.ipv4.route.max_size = 20000000 (I have tweaked a lot to keep t3 running when t1+t2 are sending as many packets as possible). The result of this efforts are somewhat odd: t1+t2 manage to send each about 200k packets/s. t4 in the best case sees aroung 200k in total so half of the packets are lost. t3 is nearly unusable on console though packets are flowing through it (high numbers of soft-irqs) the route cache garbage collector is no way near to being predictable and in the default setting overwhelmed by very few packets/s (<50k packets/s) activating stateful iptables rules makes the packet rate arriving on t4 drop to around 100k packets/s, efectively losing more than 75% of the packets And this - here is my main concern - with two old P4 machines sending as many packets as they can - which means nearly everyone on the net should be capable of this. So here goes my question: Did I overlook some importand point in the config or in my test setup? Are there any alternatives for building firewall system especially on smp systems?

• Solutions on how to use an OS X calendar as a more perfect time tracking solution for 5-10 users in a small agency?

  - by jnthnclrk

  I really like OS X's iCal. Entering events is easy with the mouse and it also gives you a very real visual sense of how long tasks take to complete. We often work remotely in our organisation, so we use a few shared calendars between key individuals to provide us with an overview of hours worked, availability & schedule conflicts without too much disruption to our various, hectic workflows. It really is a neat solution, especially on shared tasks. How many times have you tasked a remote colleague and then lost the thread on whether that task was completed or not? With shared calendars you get a much clearer idea of what your people are working on without having to pick up the phone or compose a chat. However, there are a few areas where this approach fails... iCloud syncing often needs to be re-jiggered The "view only" option on shared calendars does not seem to work, which makes all shared calendars editable by others There is no decent reporting with this workflow There is no task categorisation or tagging Things get very busy in iCal when working with more than 2 shared calendars I've looked at a few task management apps like Basecamp and Harvest, but nothing appears to let me edit my calendar natively and then sync with a 3rd party. Interested in solutions to improve the above workflow and enable us to elegantly increase the amount of users.

• mysqldump isn't able to export a specific database, phpMyAdmin crashes

  - by Devils Child

  I'm experiencing problems with a database on my server (Note: All other databases work fine). Once I try to export it with mysqldump I get this error: # mysqldump -u root -pXXXXXXXXX databasename > /root/databasename.sql mysqldump: Couldn't execute 'show table status like 'apps'': Lost connection to MySQL server during query (2013) Also, phpMyAdmin throws an error when selecting this database and immediately logs out. However, the web site which uses this database works fine. I can also execute SELECT statements on the table named "apps" from the MySQL shell. I tried restarting the MySQL daemon as well as REPAIR DATABASE and REPAIR TABLE but the problem still persists. I had this problem before, then it disappeared somehow without me doing anything to resolve the issue. Now, the problem is back and I'm simply unable to create a backup of this database.

• Is there any method of backing up Google Drive files in some sort of versioning system?

  - by VictorKilo

  Backstory My company is utilizing Google Drive for our shared files. Each user has their own Drive account. In addition, we have a corporate Drive account which holds documents which are shared to each user. Each folder is shared to different users depending on their permissions and positions in the company. Many users are able to add files, and updated folders within this shared Drive account. This is fine. What is not fine, is when someone deletes something that they shouldn't. I have little to no way of knowing when I file is deleted wrongfully. Furthermore, anything that gets deleted goes into the trash bin of the file's creator, so I can't just restore it from the trash. Question Is there any method of backing up Google Drive files in some sort of versioning system that would allow me to revert files back to defined points in time? What i have Tried I currently have this corporate drive account synced up to my personal computer through the Google Drive application. Each night, I run a backup on the file using Windows "Backup and Restore." This allows me to at least get back files that are lost, but I a cleaner method than this. It's very possible that I may not have the very latest version of a document on my computer when the utility runs.
