• I didn't mean to become a database developer, but now I am. Should I stop or try to get better?

  - by pretlow majette

  20 years ago I couldn't afford even a cheap POS program when I opened my first surf shop in the Virgin Islands. I bought a copy of Paradox (remember that?) in 1990 and spent months in a back room scratching out a POS application. Over many iterations, including a switch to Access (2000)/SQL Server (2003), I built a POS and backoffice solution that runs four stores with multiple cash registers, a warehouse and office. Until recently, all my stores were connected to the same LAN (in a small shopping center) and performance wasn't an issue. Now that we've opened a location in the States that's changed. Connecting to my local server via the internet has slowed that locations application to a crawl. This is partly due to the slow and crappy dsl service we have in the Virgin Islands, and partly due to my less-than-professional code and sql. With other far-away stores in the works, I need a better solution. I like my application. My staff knows it well, and I'm not inclined to take on the expense of a proper commercial solution. So where does that leave me? I should probably host my sql online to sidestep the slow dsl here. I think I can handle cleaning up my SQL querries to speed that up a bit. What about Access? My version seems so old, but I don't like the newer versions with the 'ribbon'. There are so many options... Should I be learning Visual Studio with an eye on moving completely to the web? Will my VBA skills help me at all there? I don't have the luxury of a year at the keyboard to figure it out anymore. What about dotnetnuke, sharepoint, or lightswitch? They all seem like possibilities, but even understanding their capabilities is daunting. I'm pretty deep into it, but maybe I should bail and hire a consultant or programmer. That sounds expensive tho, and there's no guarantee there either... Any advice would be greatly appreciated. Or, if anybody is interested in buying a small chain of surf shops...

• Are You Meeting Social Customer Service Expectations?

  - by Mike Stiles

  Whether it’s B2B or B2C, one sure path to repeat business is making sure your buyer has a memorably pleasant and successful customer service experience with you. If they get that kind of treatment consistently, that’s called a relationship. And those aren’t broken easily. Social customer service, driven by integrated SRM (social relationship management) technology, is the venue that can effectively connect customers not only to the brand, but to other customers. Positive experiences, once administered, don’t just rest with the recipient. They’re published in the form of public raves and peer-to-peer recommendation, a force far more actionable than push advertising. What’s more, your customers have come to expect access to you and satisfaction from you using social. An NM Incite study shows 83% of Twitter users and 71% of Facebook users expect to get an answer from brands the same day they post to them on their social assets. To make sure you’re responding, you’ve got to have a tech platform that’s set up to moderate and alert so you’ll know ASAP a customer needs help. The more integrated your social enterprise is, the faster you can not only respond, but respond with the answer they’re looking for, because your system is connected to the internal resources that can surface the answer or put wheels in motion to rectify the situation in the shortest amount of time possible. But if you go to the necessary lengths to make sure your customers feel valued and important, will they really reward you? The study says 71% of consumers who got quick and effective responses from companies they contacted via social were more likely to recommend the brand to their friends and followers. So yes, sweeping people off their feet pays big dividends in terms of word-of-mouth marketing. But you should be keenly aware of the reverse side of that coin. Give people a negative experience, either in real world or virtual customer service, and that message is highly likely to get amplified through social channels faster and louder. Only 36% of the NM Incite study’s respondents reported that their problems were solved quickly and effectively. 36%? That’s hardly an impressive number. It gets worse. 10% never got so much as a response - at all. Going back to the relationship analogy, companies that are this deep in the ditch where customer service is concerned are making their girl or boyfriends really easy for a competitor to steal. Given the technology tools and data available right now for having an intimate knowledge of the customer, what products they’ve purchased, likely problems with those products, effective resolutions to those problems, and follow-up communication to gauge satisfaction, there are fewer excuses than ever for making the lifeblood of your business feel like you couldn’t care less. @mikestiles

• Response: Agile's Second Chasm

  - by Malcolm Anderson

  William Pietri over at Agile Focus has written an interesting article entitled, "Agile’s Second Chasm (and how we fell in)" in which he talks about how agile development has fallen into a common trap where large companies are now spending a lot of money hiring agile (Scrum) consultants just so that they can say they are agile, but all the while avoiding any change that is required by Scrum.   It echoes the questions that I've been asking for a while, "Can a fortune 500 company actually do agile development?"  I'm starting to think that the answer is "usually not"   William ask 3 questions at the end of his article that I will answer here.   1) Have I seen agile development brought in and then preemptively customized (read: made into ScrummerFall)?   Yes, Scrum is hard and disruptive.  It's a spotlight on company dysfunction.  In a low trust environment like most fortune 500 companies Scrum will be subverted by anyone who has ever seen "transparency" translate into someone being laid off.   2) If I had to do it all over again, would I change anything?  No, this is a natural progression, but the agile principles are powerful enough, that the companies that don't adopt them will no longer be competitive and will start to fail.   3) Is this situation solvable?  I think it is.  I think that one of the issues is that you often see companies implementing Scrum, but avoiding the agile engineering practices.  I believe that you cannot do one without the other.  Scrum keeps the ship sailing in smooth deep waters.  The agile engineering practices keep the engine running smoothly and cleanly.  If you implement agile engineering practices without Scrum, you run the risk of ending up with a great running piece of software that is useful to no one.  On the other hand, implementing cargo-cult Scrum without the agile engineering practices and you end up (especially in a fortune 500 company) being steered in the right direction, but with your development practices coming to a dead halt because you have code that can not keep up with the changes in requirements.   If you are trying to do Scrum, make sure that you hire some agile engineering coaches, or else you may find your deveolpment engines grinding to a dead halt in the middle of the open ocean.

• Rolling With the Punches

  - by D'Arcy Lussier

  So I’ve been tweeting the last little while “Rolling with the punches” and I’ve had some people ask me what that meant. Whether you’re running a conference (like I am this week), or a project, or a birthday party for a 2 year old, you need to be ready to handle those things that are unexpected. Risk mitigation can only go so far and its at those times that you need to become resourceful. So let me tell you what the last few days have been like. Today is the first day of Prairie Dev Con Winnipeg, a conference that I run. On Friday I was informed that my keynote speaker had lost his voice, one of my speakers had a family emergency and had to back out, and I got a warning from another that he was travelling over the weekend and if there was a storm or something he may not be able to get back by Monday for his talk. A storm didn’t happen, but their car did break down and he was delayed. Finally, Saturday night I took my printing order to Staples. It was at 5 and they closed at 6, and I had a bunch of surveys to be printed and cut. The girl working said that she’d have it ready by the next day (Sunday). Her intent was to come in the next morning and finish the job. Unfortunately, she had to be hospitalized that night and never made it into work…and never informed anyone of the remaining work. They found out at 3pm when I came to pick it up and there was no way they’d be able to cut everything in time. So how did we roll with these punches? - Miguel, my keynote speaker, was a trooper and was able to do the keynote but asked that his session get moved from Monday to Tuesday. This is why I wait until the last day before printing out schedules, they can change up to the event and even later. - I was able to move some sessions around to accommodate my stranded speaker and fill the empty slot from the speaker that couldn’t make it. - Staples was able to get me half the cut surveys so I took those and my wife will pick up the rest today. I altered how we’d collect session surveys, and actually I think it’ll work better. So all of this is to say, plan but also plan for what you can’t plan for – there will be things that happen that blindside you, that you’re not sure how to handle or solve. Stop, take a deep breath, and don’t feel that you need to limit yourself to the boundaries that you initially set for yourself. Roll with the punch and learn from it so that you can avoid the blow next time. Now, back to the conference! D

• How do I connect two computers with a LAN cabel?

  - by John

  I have two machines - Windows XP and a laptop using Windows 7. I connected them with a WLAN cable. On the Windows XP machine, I set the IP address to 192.168.0.10. On the Windows 7 laptop, I set the IP address to 192.168.0.20. The laptop can see the Windows XP machine, but Windows XP machine cannot see the Windows 7 machine. But this does NOT concern me. I want to move the files from my desktop (Windows XP) to Windows 7 (laptop). That's why I'm going through all this. The problem is that when I try to connect from Windows 7 to Windows XP machine, I get this window: I don't understand what username/password is needed. I use none on the Windows XP machine. I tried all usernames - no success. Please explain in deep details how to solve my problem so I can connect to my Windows XP machine. EDIT: Maybe this can help: the Windows XP machine is named 'I' and '???????? III' is the name of the laptop. Both computers share one workgroup - WORKGROUP.

• MacBook Pro 13" Install DVD Wont Start

  - by Belliez

  Hi, Excuse such a basic question... I am a Laptop Fixer and deal with Windows based laptops only but very recently took in a 13" MacBook Pro for a re-install of the OS (easy I thought!) I inserted the Install DVD, held the C button and turn on. I could hear the disk spinning up and after about a min the DVD is ejected. There are a few scratches on the DVD but should be ok as not that deep. However, Windows Vista was installed (it failed to install properly hence the re-install of Mac OS). Should I wipe clean and format the hard disk first? Could this be the reason the DVD is ejected? Any advice would be gratefully accepted? p.s. never held a MacBook Pro before... first impressions, wow... alu casing and massive touch pad... and the magnetic power socket.... so impressed and it doesn't even work!

• authbind, privbind or iptables REDIRECT (port 80 to 8080)?

  - by chris_l

  Hi, I'd like to run Glassfish v3 as a non-privileged user on Linux (Debian), but make it available on port 80. I'm currently doing this with iptables: iptables -t nat -I PREROUTING -p tcp -d x.x.x.x --dport 80 -j REDIRECT --to-port 8080 This works, but I wonder: If this has any significant performance impact compared to binding directly to port 80 If I could make a similar setup also work for HTTPS (or if that must run on 443) If there's a way to avoid other users from binding to port 8080 (in case my server crashes) - maybe block that port permanently to other users somehow? ...or if I should use authbind/privbind instead? Problem: I couldn't make it work with authbind or privbind so far. For authbind, I edited asadmin's last line to: exec authbind --deep "$JAVA" -Djava.net.preferIPv4Stack=true -jar ... For privbind: exec privbind -u glassfish "$JAVA" -Djava.net.preferIPv4Stack=true -jar ... (Only) with these settings, I can successfully perform a create-domain --domainport 80. This proves, that authbind and privbind actually work (the authbind version of the script is called by the glassfish user; the privbind version is called by root of course). However, in both cases I get the following exception, when starting the domain (start-domain): [#|2010-03-20T13:25:21.925+0100|SEVERE|glassfishv3.0|javax.enterprise.system.core.com.sun.enterprise.v3.server|_ThreadID=11;_ThreadName=FelixStartLevel;|Shutting down v3 due to startup exception : Permission denied: 80=com.sun.enterprise.v3.services.impl.monitor.MonitorableSelectorHandler@1fc25e5|#] I haven't found a solution for that yet (after searching the web, it seems, that this isn't so easy?) But maybe, the solution with iptables is good enough - what do you think? Thanks, Chris

• How to replicate Lynda.com transitions in my own presentations (Keynote preferred, Powerpoint possib

  - by jdmuys

  I recently noticed that lynda.com uses in their training videos a very interesting transition that I would like to replicate in my own presentations. They are somewhat similar to the computer screen animations in the "Minority Report" movie: they zoom out to a huge sheet, pan, and zoom back in to a new location. It's very good for navigating deep hierarchies. For example when you are at level 1, you can see level 3, but it's tiny and unreadable. You then transition by zooming in to a deeper level that suddenly becomes legible. I can imagine also to use it using a large "mind map" as a common Ariane thread, to dive into details (and back out) while still taking advantage of the visual memory of the audience. It a bit difficult to describe, I hope I managed to convey the idea. You can see them in action for example there (iPhone programming training): http://www.lynda.com/home/DisplayCourse.aspx?lpk2=48369 Then click on "What you should know" in the introduction chapter. See for example in that movie between 22s and 24s, then between 27s and 28s. How do they do that? How could I replicate that effect? TIA

• Distributed development staff needing a common IP range

  - by bakasan

  I work on a development staff that is geographically distributed, mostly all throughout the state of CA, but several key members also must travel frequently. We rely quite heavily on a 3rd party provider API for a great deal of our subsystems (can't get into who it is or what they do). The 3rd party however is quite stringent on network access and have no notion of a development sandbox. Access is restricted to 2, 3 IP numbers and that's about it. Once we account for our production servers, that leaves us with an IP or two to spare for our dev team--which is still problematic as people's home IP changes, people travel, we have more than 2 devs, etc. Wide IP blocks are not permitted by the 3rd party. Nor will they allow dynamic DNS type services. There is no simple console to swap IPs on the fly either (e.g. if a dev's IP at home changes or they are on the road). As none of us are deep network experts, I'm wondering what our viable options are? Are there such things as 3rd party hosts to VPNs? Generally I think of a VPN as a mechanism to gain access to a home office, but the notion would be a 3rd party VPN that we'd all connect to and we'd register this as an IP origin w/ our 3rd party. We've considered using Amazon EC2 to effectively host a dev environment for each dev and using that to connect. Amazon only gives you so many static IPs however (I believe 5?) so this would only be a stop gap solution until our team size out strips our IP count at Amazon. Those were the only viable thoughts that I had, but again, I'm far from a networking guy. Tried searching for similar threads, but I'm not even sure I know the right vernacular to look around for.

• Time drift in Cloud Server - need to mainpulate GRUB config

  - by Aditya Advani

  We are hosting a VPS on a popular host and are experiencing a regular time drift of several minutes a day forward (approx 7). Linux Kernel: 2.6.18-164.11.1.el5 GNU/Linux Distro: CentOS release 5.4 (Final) We reached out to our hosting provider and their support advised us " This is a known issue with Cloud Servers. To fix this you will need to add one line to your grub config located at: /boot/grub/menu.lst The line you need to add is: noapic nolapic divider=10 nolapic_timer This should correct this issue. You will need to restart after this is added in. " Because I am wary of manipulating grub, mostly I'm terrified that our server may fail to restart - I ask you guys, the pro *nix admins - where exactly in this file does the recommended insertion below: # line from 1&1 for time syncing issue (Case 5163) noapic nolapic divider=10 nolapic_timer go? Please specify where exactly, and whether the order of commands is or is not important. Why is the block below "title CentOS ..." indented? If someone could give me an overview of how this works or point me to a resource that's easy to follow, that's what I'm looking for immediately, a light overview or basic understanding of what I;m doing. If GRUB and bootloaders are a deep dark treasure trove of kernel hacking or something, that's great well-recommended in-depth resources are also very welcome. This is my current /boot/grub/menu.lst # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file #boot=/dev/sda # serial --unit=0 --speed=57600 terminal --timeout=5 serial console timeout=5 title CentOS (2.6.18-164.11.1.el5) root (hd0,0) kernel /boot/vmlinuz-2.6.18-164.11.1.el5 ro root=/dev/hda1 console=tty0 console=tty initrd /boot/initrd-2.6.18-164.11.1.el5.img MOST IMPORTANT: I need to know where in the file above it is appropriate to paste the suggested line so I can confidently restart my VPS after manipulating GRUB config

• htaccess not properly rewriting urls

  - by Cameron Ball

  This is a bit of a weird one. I'm doing some work on a server, and I need rewrite rules for directories that actually exist (in some cases, they are more than one level deep) At the moment my .htaccess looks like this: RewriteEngine on RewriteRule ^simfiles/([-\ a-zA-Z0-9:/]+)$ http://mydomain.com/?portal=simfiles&folder=$1 [L] And this is working OK, for example, a url like: mydomain.com/sifmiles/my-files Will get redirected to mydomain.com/?portal=simfiles&folder=my-files Or in the case of a directory structure that is deeper than one level: mydomain.com/sifmiles/my-files/more-of-my-files Will get redirected to mydomain.com/?portal=simfiles&folder=my-files/more-of-my-files I wrote the regex so that it won't match things with a . in the path, because there are css and js files which reside in simfiles/somedirectory, and if I redirect everything then these cannot be loaded. I tried a configuration like this: RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^simfiles/([-\ a-zA-Z0-9:/\.]+)$ http://mydomain.com/?portal=simfiles&folder=$1 [L] But that doesn't work, things still don't load properly. So my first question is, how can I achieve this "properly"? I don't like my solution because it means redirects won't occur if the folder has a . in its name. My second problem, is that while the redirection is happening properly, the url becomes: http://mydomain.com/?portal=simfiles&folder=my-files I want the URL to remain clean, like: http://mydomain.com/sifmiles/my-files How can I achieve this?

• What do I need in order to extract and combine text files from multiple ZIP files, via command line?

  - by Iszi

  I've got an interesting scripting challenge in front of me. I'm fairly certain there's a way to do it, but I feel like I'm probably lacking some particular tools and/or functional knowledge. There's some fifty-plus ZIP files that each contain, among other things, text files that need to be merged with one another. The structure is something like this: C:\Reports\FirstJob-1.zip |-MyName |-FirstJob |-1 |-[Some other folders] |-TXTReports |-English |-[Some other files] |-Report.txt C:\Reports\FirstJob-2.zip |-MyName |-FirstJob |-1 |-[Some other folders] |-TXTReports |-English |-[Some other files] |-Report.txt C:\Reports\SecondJob-1.zip |-MyName |-SecondJob |-1 |-[Some other folders] |-TXTReports |-English |-[Some other files] |-Report.txt If I had all the Report.txt files in one regular folder, and uniquely named, I could probably just write a FOR statement that targets *.txt and runs something like type filename.txt >> Consolidated.txt on each. However, these all have the same file name and are embedded deep within separate ZIP files. The potentially useful tools I currently have at my disposal are Windows XP Professional SP3, PowerShell, and WinZip. I'd rather not download or install anything else, but I do understand that third-party tools (or additional tools from Microsoft or WinZip) may be necessary. Whatever tools I use should run natively in Windows. I really don't want to have to mess with Cygwin or other emulators on this system. At the very least, I need a tool that will allow me to analyze and manipulate ZIP files from the command line. Also, are there any other particular complications to this that I've not yet thought of?

• what's the difference between a Volume and a Partition in Windows 7 diskpart

  - by user170232

  I was trying to follow the Intel guide for setting up iRST (Intel Rapid Start Technology) on my new laptop. The Intel manual says you need to create a *Volume that is as big or bigger than your available memory, set it to a specific id (id=84), then go into the iRST tool and adjust some settings. Looking at the disk manager on the laptop, I see there is already a Partition labeled as "Hibernation Partition" which is a little bigger than the memory in my system. So it looks like iRST was already set up...BUT, it's a Partition, not a Volume. Here's what the manual says to do: (from: http://download.intel.com/support/motherboards/desktop/sb/rapid_start_technology_user_guide.pdf) diskpart list disk select disk x (where x is the disk to use, there's only one disk in this laptop) create partition primary size=X000 (where X000 is the size to create) detail disk (which lists details for the disk. This is where i get hung up) select volume Z (where Z is the *partition you created previously) ** it says the 'detail disk' command will list the volume #, but it doesn't. ** 'detail disk' only lists two "volumes" for Recovery and OS. ** if i do 'list partition', i see the 8 GB *partition labeled as "Hibernation Partition") ** so I can't continue with the following steps: set id=84 override exit The reason I went looking for the manual is because when iRST is enabled in the BIOS, the system won't resume from sleep. When it's disabled, it works fine, but the system goes into (legacy?) Hibernation mode and takes a while to come out of Hibernation. the iRST is supposed to resume from deep sleep very quickly. So, what's the difference between a Volume and a Partition? Should I delete the Hibernation Partition and create a Hibernation Volume? Anyone have any ideas? (if it matters, this is on a Dell XPS 13 with BIOS A08) Thanks! J

• ProCurve network expansion

  - by Blue Warrior NFB

  I've hit a bit of a wall with our network scale-out. As it stands right now: We have five ProCurve 2910al switches connected as above, but with 10GbE connections (two CX4, two fiber). This fully populates the central switch above, there will be no more 10GbE Ethernet connections from that device. This group of switches is not stacked (no stack directive). Sometime in the next two or three months I'll need to add a sixth, and I'm not sure how deep of a hole I'm in. Ideally I'd replace the core switch with something more capable and has more 10GbE ports. However, that's a major outage and that requires special scheduling. The two edge switches connected via fiber have dual-port 10GbE cards in them, so I could physically put another switch on the far end of one of those. I don't know how much of a good or bad idea that would be though. Is that too many segments between end-points? Some config-excerpts: Running configuration: ; J9147A Configuration Editor; Created on release #W.14.49 hostname "REDACTED-SW01" time timezone 120 module 1 type J9147A module 2 type J9008A module 3 type J9149A no stack trunk B1 Trk3 Trunk trunk B2 Trk4 Trunk trunk A1 Trk11 Trunk trunk A2 Trk12 Trunk vlan 15 name "VM-MGMT" untagged Trk2,Trk5,Trk7 ip helper-address 10.1.10.4 ip address 10.1.11.1 255.255.255.0 tagged 37-40,Trk3-Trk4,Trk11-Trk12 jumbo ip proxy-arp exit

• Permissions won't cascade more than 1 level

  - by Jovin_

  Running Windows Small Business Server 2011 I have a file structure with a lot of sub folders (sometimes 5-6 levels deep). I have created access groups to grant access to my users, and also deny groups to deny access to others. X Access & X Deny. These allow or deny access to a mapped network drive X: On the server I put in the groups with Full Control Allow for X Access and Full Control Deny for X Deny, I also tick the box "Apple these permissions to objects and/or containers within this container only" and have ensured that "Apply to:" is "This folder, subfolders and files". But for some reason the permissions will only apply to the next level of folders & files. ex. structure: X: Folder 1 Folder 1a Folder 2 Folder 2a If I apply the permissions to X: it'll only go to Folder 1 & 2, not 1a and 2a, I then need to manually apply the permissions to these too. Is this working as intended or am I doing something wrong?

• PDFs and Networked Printers

  - by Bart Silverstrim

  Weird issue. We have users printing to networked windows-shared printers (print server Win2003 sp2). Some users have been reporting recently that they can't print PDF documents to particular printers (two example printers are HP 2430 PCL 6 driver and 4250 PCL 6 driver). At first, we found that on many of these systems the "Everyone" object was added to the permissions for the root of the C: volume but had no permissions checked. We added modify privileges to it (these are Deep-Freeze systems, so modifications to these systems that we don't add as administrators won't matter) and they seemed to be able to print. Perhaps Acrobat Reader was writing a temp file for printing where users didn't have permission, we surmised, and made the change and moved on. Yesterday the user called in saying it's not working still. Looked at it; bring up a PDF, click Print and the reader app says that you have to install a printer. Look at the printers folder (Windows XP workstation), and it has printers installed. Print a test page, return to AcroReader, and it will print fine to that printer. The whole time web pages, MS Office documents, etc. print without issue to the same printers. Has anyone seen this issue with Acro Reader 9 and certain network printer drivers or shares involving HP printers? I'd post this to SuperUser but it seems to be associated with a networked printer issue, seems to affect subsets of users but may be more widespread and our users aren't reporting it to us assuming we just know about it, and I've not found rhyme or reason as to why it's affecting just PDF printing and particular printers. The print spoolers are all running on the workstations and print server without errors being logged so far, but I'm going through the logs now to see if I can find anything out of place.

• Resize a RAID 1 volume on OSX Snow Leopard - how? (Note: software raid)

  - by Emmel

  I've scoured the Internet in search of an answer to this question, and as usual with OSX-related topics, I often don't find any deep-dive technical explanations sufficient enough to feel confident doing dangerous things. Here is my question: I have a Mac Pro, running OSX 10.6.2. I have, as my main root/boot disk, a RAID 1 volume called "Mirror1". Mirror1 is comprised of two 1 TB disks. Mirror1, however, is fixed at 640 GB. That's because, I originally took a 640GB disk, bought a terabyte disk, mirrored it (using diskutil appleraid enable...), when it synced I removed the 640GB and replaced it with a second 1 TB disk, and synced again. Voila! A single 640 GB replaced by two 1 TB disks in a mirror.. Actually, no. There's still something missing from the equation: Mirror1 needs to be expanded from 640GB to 1 TB to match the partition sizes on each of those disks. How do I do this? Perhaps the diskutil output will help: -> diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI 209.7 MB disk0s1 2: Apple_RAID 999.9 GB disk0s2 3: Apple_Boot Boot OSX 134.2 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk1 1: EFI 209.7 MB disk1s1 2: Apple_RAID 999.9 GB disk1s2 3: Apple_Boot Boot OSX 134.2 MB disk1s3 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *640.1 GB disk2 1: EFI 209.7 MB disk2s1 2: Apple_HFS Mac Disk 2 536.7 GB disk2s2 3: Microsoft Basic Data BOOTCAMP 103.1 GB disk2s3 /dev/disk3 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Mirror1 *639.8 GB disk3 -> diskutil appleraid list AppleRAID sets (1 found) =============================================================================== Name: Macintosh HD Unique ID: 1953F864-B474-4EB6-8E69-41834EBD0247 Type: Mirror Status: Online Size: 639.8 GB (639791038464 Bytes) Rebuild: manual Device Node: disk3 ------------------------------------------------------------------------------- # Device Node UUID Status ------------------------------------------------------------------------------- 0 disk1s2 25109BAE-5697-40EA-B612-0217851444F7 Online 1 disk0s2 11B83AB0-8148-4DB6-8761-DEF08C855F8D Online =============================================================================== Thanks in advance.

• Suggestions for Windows 8 migration [closed]

  - by Big Endian

  I'm thinking of migrating to Windows 8. At first I hated it, but I'm pretty sure the Windows 8 model is the future, and I don't particularly want to end up hating the future like my parents, frustrated and bewildered by anything past Windows XP. I'm currently running Windows 7 and my system has been accumulating some problems. It's probably an accumulation of issues from installing too much software, changing firewall settings, installing Ubuntu alongside Windows, and... well I'm not sure, but my computer has been buggy in unexpected ways lately (freezing and unfreezing, display driver crashing and recovering, and what I call "deep freeze/thaw cycle" where the mouse won't even move for a while). I'm good at solving computer problems, but I can't seem to get to the root of these and my best idea for fixing them is making sure I've backed up every file then re-installing the entire OS. Luckily for me, a new OS is just around the corner so this would be a good time to get two things out of the way at once. The problem I see is that the upgrade options I see are all "seamless". I don't want a seamless upgrade. I want to wipe the slate clean and start all over. Does this mean I will have to buy a full, new copy of Windows 8 rather than one of the cheaper upgrading options? Or does it not make since for me to go to Windows 8 given that I have a laptop, not a tablet? Maybe I should just re-install Windows 7, or even call good enough good enough, try to eliminate the bugs, and start with a fresh slate in 2-3 years after this computer eventually dies entirely from (inevitable) hardware failure. What would be the advantages or disadvantages and costs of each option, how would I go about upgrading to Windows 8 if that's the option I choose, and what is your personal opinion about my situation?

• How Do I Install Latest Java Plugin on Ubuntu 8.04 LTS with Custom Firefox 3.6.3?

  - by Volomike

  I have Ubuntu 8.04 LTS and will need to remain on that for awhile as I am a programmer and cannot disturb what I'm doing in the middle of a project. As you know, it doesn't want to install the latest Firefox by default and keeps me in the stone age. So, I had to install my own Firefox. I did so and with relative ease I was able to install the Flash plugin using the normal 'ln -s' technique one usually does with /usr/lib/firefox/plugins. Now I need to do a Gotomypc.com task and it requires Java -- moan -- so I need to figure out how to install Java. I downloaded and installed the latest Java plugin in /usr/java, and I do see underneath that layer of folders a plugins folder with a .so file. So, I went to /usr/lib/firefox/plugins and did this: ln -s /usr/java/jre1.6.0_20/plugin/i386/ns7/libjavaplugin_oji.so Then, I also read on the web that one has to create a ~/.mozilla/plugins folder, cd into it, and then run the same ln -s command again. Another site recommended finding one's ~/.mozilla/firefox and renaming it to ~/.mozilla/firefox.old (after you backed up your bookmarks) and then launching firefox again so that it creates ~/.mozilla/firefox and uses the new Java plugin. Well, all these attempts have completely failed and it is incredibly frustrating. I do about:plugins to see my plugins and all I get are the Flash and the default null plugin. I do not see the Java one. Also, they said on my tools menu with Firefox 3.6.3 I would see a Java Console menu and I don't see that either. I found a pluginreg.dat somewhere deep under ~/.mozilla/firefox, but it does not list the Java plugin inside -- only Flash and the null plugin. Please help me install Java. I need to help a client out and need to connect to his PC remotely with gotomypc, which requires Java inside firefox.

• 8007064c(2011) and 80280007(2009) persistant after all known repairs

  - by tiu44

  I'm on Windows 7 Home x64, and have ran into a major issue with Live Messenger(which I use daily). I have full offline installers for both 2011 and the last Wave 3 2009(14.0.8117.0416) Suites. Both give the following errors: Live Essentials 2011 Offline installer(official): An unknown error occured. Error:0x8007064c Source WLXSuite WL 2009 offline installer(official): You already have a more recent version of Windows Live. Error: OnCatalogResult:0x80280007 Next steps: If you want to install this older version, first uninstall any later versions that are on your computer. Get help with this error The 2011 installer also says it is updating messenger, I don't select anything else. Then last 2009 installer says their is a newer version that needs uninstalled even after the following procedures. MS Help pages provided all basically lead to using uninstall from control panel. Which I've uninstalled all Live components including watcom safety scanner and portable SQL from. I've followed online instructions for manually deleting folders from Program Files(x86), Appdata, and some others under \User\All Users and the one for the one account on the machine. I've used CCcleaner 3.01, ASC 3.7.3 and Beta 4 with deep scan along with deleting folders, and checked their uninstallers for Live components too, and none were there. wlmuninstaller.exe tool reports nothing, but after a failed install it finds something, but failes to clean it under all user admin privilege. The same errors still occur after all of that. Google searching I see people on forums suggesting reinstalling the OS cause MS doesn't even know how to fix this, but I'm hoping someone here can help. NOTE: I don't have System Restore or any other state freeze utilities going, and I don't have any real time AV going(I sometime scan with defender, anti rootkits, and online scanners). NOTE2:I posted this on windowslivehelp.com, before looking to see if the place was active or not, hoping I can get help here. Thanks

• Windows XP error message: "Windows cannot find 'explorer.exe'"

  - by Meysam

  In Windows XP I can open "My Computer" and see all the hard drives. I can also see the explorer.exe process running among other processes in Task Manager. But after opening "My Computer", when I double click on one of the drives to open it, I get the following error message: Windows cannot find 'explorer.exe'. Make sure you typed the name correctly, and then try again. To search for a file, click the start button, and then click search. Although I could detect and remove several suspicious files using Malwarebytes & Microsoft Security Essentials, the problem still remains. The interesting point is that if I right click on one folder and select Open or Explore from the menu bar, I can open the folder! but if I double click on the folder, it does not open and I get the above error message. How can I fix this problem? Any advice would be appreciated! Update: I formatted the C: drive (NTFS), a deep format, and installed a fresh Windows XP on it. I am not getting this error when I double click on C drive icon anymore. But the same error appears when I double click on other drive names. Maybe I should format them too!

• Suggestions on the best home server rack cabinet

  - by allentown

  I have a lot of gear in a colocation facility right now. Some of it is going to come home with me now. I do not know anything about the "rack mount" side of the industry. I lease a rack, and I put my stuff in it. I have a few 1U boxes, a few 2U boxes, and a few 4U boxes. 1U switch. One is a new Xserve, which means it is deep. I think I can get by with around 12U to 18U. I want to keep it as small as possible, since I do not have a lot of spare space at my home. I will not be able to bolt to the wall, floor etc, so it should not be tall. This is something I would love to more or less just be a box that sits on the floor but gives me the ability to mount nicely, do nice cable management etc. Are the "post" style racks junk? I am liking the open space, and the no limitations on depth of something like this: http://www.rackmountsolutions.net/images/products/Martin-relay-rack.jpg However, that thing is way too tall, and probably way too expensive. I am looking to be around $300.00 or less. More if I have to, though I would prefer not to. These look near perfect: (See comment for this link, the system will not let me post a second url) but I am worried the Xserve will not fit in it. If anyone has any good links, or website recommendations of good past experience, I would appreciate it. I am almost considering that I may be able to build something with random scraps of stuff at Home Depot as well.

• How do I calculate clock speed in multi-core processors?

  - by NReilingh

  Is it correct to say, for example, that a processor with four cores each running at 3GHz is in fact a processor running at 12GHz? I once got into a "Mac vs. PC" argument (which by the way is NOT the focus of this topic... that was back in middle school) with an acquaintance who insisted that Macs were only being advertised as 1Ghz machines because they were dual-processor G4s each running at 500MHz. At the time I knew this to be hogwash for reasons I think are apparent to most people, but I just saw a comment on this website to the effect of "6 cores x 0.2GHz = 1.2Ghz" and that got me thinking again about whether there's a real answer to this. So, this is a more-or-less philosophical/deep technical question about the semantics of clock speed calculation. I see two possibilities: Each core is in fact doing x calculations per second, thus the total number of calculations is x(cores). Clock speed is rather a count of the number of cycles the processor goes through in the space of a second, so as long as all cores are running at the same speed, the speed of each clock cycle stays the same no matter how many cores exist. In other words, Hz = (core1Hz+core2Hz+...)/cores.
