• SQL Saturday 27 (Portland, Oregon)

  - by BuckWoody

  I’m sitting in the Seattle airport, waiting for my flight to Silicon Valley California for the SQL Server 2008 R2 Launch Event. By some quirk of nature, they are asking me to Emcee the event – but that’s another post entirely.   I’m reflecting on the SQL Saturday 27 event that was just held in Portland, Oregon this last Saturday. These are not Microsoft-sponsored events – it’s truly the community at work. Think of a big user-group meeting – I mean REALLY big – held in a central location, like at a college (as ours was) or some larger, inexpensive venue like that. Everyone there is volunteering – it’s my own money and time to drive several hours to a hotel for the night, feed myself and present. It’s their own time and money for the folks that organize the event – unless a vendor or two steps in to help. It’s their own time and money for the attendees to drive a long way, spend the night and their Saturday to listen to the speakers. Why do all this?   Because everybody benefits. Every speaker learns something new, meets new people, and reaches a new audience. Every volunteer does the same. And the attendees? Well, it’s pretty obvious what they get. A 7Am to 10PM extravaganza of knowledge from every corner of the product. In fact, this year the Portland group hooked up with the CodeCamp folks and held a combined event. We had over 850 people, and I had everyone from data professionals to developers in my sessions.   So I’ll take this opportunity to do two things: to say “thank you” to all of the folks who attended, from those who spoke to those who worked and those who came to listen, and to challenge you to attend the next SQL Saturday anywhere near you. You can find the list here: http://www.sqlsaturday.com/. Don’t see anything in your area? Start one! The PASS folks have a package that will show you how. Sure, it’s a big job, but the key is to get as many people helping you as possible. Even if you have only a few dozen folks show up the first time, no worries. The first events I presented at had about 20 in the room. But not this week.   See you at the Launch Event if you’re near the San Francisco area tomorrow, and see you at the Redmond SQL Saturday and TechEd if not.   Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• First Impressions of a MacBook (from a PC guy)

  - by dgreen

  Disclaimer: I've been a PC guy my entire working career. I'd probably characterize myself as a power user. Never afraid to bust out the console line. But working with a Mac is totally foreign to me. So for those Mac guys who are curious, this is how your world appears from the outside to a computer literate person :)My Macbook Air has arrived! And it's a thing of beauty:First, the specs: 13" MacBook Air, 2.0GHz Core i7 processor. Upgraded to 8GB of RAM for an additional $100, SSD flash storage  = 256GB. The plan is ultimately to use this baby for some iOS development but also some decent lifting in Windows with Visual Studio. Done a lot of reading  and between VMWare Fusion, Parallels and Bootcamp...I'm going to go with VMWare Fusion for $49.99And now my impressions (please re-read disclaimer before proceeding!):I open the box and am trying to understand exactly how the magsafe connector works (and how to disconnect it).  Why does it have two socket outlet plugs? Who knows.  I feel like Hansel in Zoolander. The files are "in" the computer.Stuck in my external hard drive (usb). So how do I get to the files? To the Googles!Argh...it can't read my external NTFS drive. Fat32 can't support field over 4GB…problematic since some of my existing VMWare image files are much larger than 4GB. Didn't see this coming.Three year old loves iPhoto. Super easy to use. Don't even know what I'm doing but I've already (accidentally) discovered the image filtering options. Fun stuff.First thing I downloaded ever => Chrome. I need something to ground me, something familiar. My token, if you will (sorry, gratuitous Inception joke).Ok, I get it… Finder == windows explorer. But where is my hierarchical structure? I miss the tree :(On that note, yeah…how do I see what "path" my files reside in? I'm afraid to know the answer. You know what scares more though…this notion of a smart folder. Feel like the godfather - just get the job done, I don't care how you handle it, I don't want to know...just get it done. What the hell is AirDrop?Mail…just worked. Still in shock that they have a free client for yahoo mail (please no yahoo jokes).mail -> deleting a message takes 5 seconds. Have they heard of async?"Command" key instead of "Control" ok, then what the $%&^! is the control key for then"aliases" == shortcuts I thinkI don't see the file system. And I'm scared. All these things I'm downloading…these .dmg files (bad name) where are they going? Can't seem to delete when they're doneUgh...realized need to buy a mini-to-vga adaptor if I want to use my external monitor ($13 on ebay, $39 in apple store).Windows docking is trickiest for me…this notion of detached windows with a menu bar at the top. I don't like this paradigm, it's confusing. But maybe because I've been using Windows for too long.Evernote, Dropbox desktop clients seem almost identical…few quirks here and there I need to get used to.iTunes is still a bit gross. In a weird way it's actually worse on a Mac if thats possible. This is not the MacBook's fault…this is a software design issue. Overall: UI will take some getting used to. Can't decide if this represents the future and I'm stuck in the past…or this is the past and I've been spoiled by the future (which would be Windows…don't be hating I happen to be very productive in Win7)  So there you go - my 90 minute first impression of the MacBook universe.

• Can't boot in Ubuntu after windows upgrade

  - by VanceAnce

  After my lastest update for Ubuntu and Windows XP, I got a Grub error on booting the next day. ls lists the following (without () ): sd0 sd1, msdos sd2 sd5 sd6 When I tried to get into one with (sd0,xy)/ it doesn't detect system or unknown file system error. I tried to boot to a live session with a Knoppix live CD and found out that all data exists. I also tried to recover with TestDisk and it finds all systems. Here is the test disk result: Start End Size in sectors 1 * HPFS - NTFS 0 1 1 7079 254 63 113740137 2 E extended LBA 7080 0 1 12161 254 63 81642330 5 L HPFS - NTFS 7080 1 1 10266 254 63 51199092 [Schule] X extended 12031 30 1 12161 254 63 2102625 6 L Linux Swap 12031 31 33 12161 254 63 2102530 I've 1 winxp-home, 1x Ubuntu (ext3+swap) and 1 winxp prof and then I wrote on mbr with TestDisk but I always get the same errors with Grub.

• Ask HTG: How Can I Check the Age of My Windows Installation?

  - by Jason Fitzpatrick

  Curious about when you installed Windows and how long you’ve been chugging along without a system refresh? Read on as we show you a simple way to see how long-in-the-tooth your Windows installation is. Dear How-To Geek, It feels like it has been forever since I installed Windows 7 and I’m starting to wonder if some of the performance issues I’m experiencing have something to do with how long ago it was installed. It isn’t crashing or anything horrible, mind you, it just feels slower than it used to and I’m wondering if I should reinstall it to wipe the slate clean. Is there a simple way to determine the original installation date of Windows on its host machine? Sincerely, Worried in Windows Although you only intended to ask one question, you actually asked two. Your direct question is an easy one to answer (how to check the Windows installation date). The indirect question is, however, a little trickier (if you need to reinstall Windows to get a performance boost). Let’s start off with the easy one: how to check your installation date. Windows includes a handy little application just for the purposes of pulling up system information like the installation date, among other things. Open the Start Menu and type cmd in the run box (or, alternatively, press WinKey+R to pull up the run dialog and enter the same command). At the command prompt, type systeminfo.exe Give the application a moment to run; it takes around 15-20 seconds to gather all the data. You’ll most likely need to scroll back up in the console window to find the section at the top that lists operating system stats. What you care about is Original Install Date: We’ve been running the machine we tested the command on since August 23 2009. For the curious, that’s one month and a day after the initial public release of Windows 7 (after we were done playing with early test releases and spent a month mucking around in the guts of Windows 7 to report on features and flaws, we ran a new clean installation and kept on trucking). Now, you might be asking yourself: Why haven’t they reinstalled Windows in all that time? Haven’t things slowed down? Haven’t they upgraded hardware? The truth of the matter is, in most cases there’s no need to completely wipe your computer and start from scratch to resolve issues with Windows and, if you don’t bog your system down with unnecessary and poorly written software, things keep humming along. In fact, we even migrated this machine from a traditional mechanical hard drive to a newer solid-state drive back in 2011. Even though we’ve tested piles of software since then, the machine is still rather clean because 99% of that testing happened in a virtual machine. That’s not just a trick for technology bloggers, either, virtualizing is a handy trick for anyone who wants to run a rock solid base OS and avoid the bog-down-and-then-refresh cycle that can plague a heavily used machine. So while it might be the case that you’ve been running Windows 7 for years and heavy software installation and use has bogged your system down to the point a refresh is in order, we’d strongly suggest reading over the following How-To Geek guides to see if you can’t wrangle the machine into shape without a total wipe (and, if you can’t, at least you’ll be in a better position to keep the refreshed machine light and zippy): HTG Explains: Do You Really Need to Regularly Reinstall Windows? PC Cleaning Apps are a Scam: Here’s Why (and How to Speed Up Your PC) The Best Tips for Speeding Up Your Windows PC Beginner Geek: How to Reinstall Windows on Your Computer Everything You Need to Know About Refreshing and Resetting Your Windows 8 PC Armed with a little knowledge, you too can keep a computer humming along until the next iteration of Windows comes along (and beyond) without the hassle of reinstalling Windows and all your apps.

• Organization &amp; Architecture UNISA Studies &ndash; Chap 6

  - by MarkPearl

  Learning Outcomes Discuss the physical characteristics of magnetic disks Describe how data is organized and accessed on a magnetic disk Discuss the parameters that play a role in the performance of magnetic disks Describe different optical memory devices Magnetic Disk The way data is stored on and retried from magnetic disks Data is recorded on and later retrieved form the disk via a conducting coil named the head (in many systems there are two heads) The writ mechanism exploits the fact that electricity flowing through a coil produces a magnetic field. Electric pulses are sent to the write head, and the resulting magnetic patterns are recorded on the surface below with different patterns for positive and negative currents The physical characteristics of a magnetic disk   Summarize from book   The factors that play a role in the performance of a disk Seek time – the time it takes to position the head at the track Rotational delay / latency – the time it takes for the beginning of the sector to reach the head Access time – the sum of the seek time and rotational delay Transfer time – the time it takes to transfer data RAID The rate of improvement in secondary storage performance has been considerably less than the rate for processors and main memory. Thus secondary storage has become a bit of a bottleneck. RAID works on the concept that if one disk can be pushed so far, additional gains in performance are to be had by using multiple parallel components. Points to note about RAID… RAID is a set of physical disk drives viewed by the operating system as a single logical drive Data is distributed across the physical drives of an array in a scheme known as striping Redundant disk capacity is used to store parity information, which guarantees data recoverability in case of a disk failure (not supported by RAID 0 or RAID 1) Interesting to note that the increase in the number of drives, increases the probability of failure. To compensate for this decreased reliability RAID makes use of stored parity information that enables the recovery of data lost due to a disk failure.   The RAID scheme consists of 7 levels…   Category Level Description Disks Required Data Availability Large I/O Data Transfer Capacity Small I/O Request Rate Striping 0 Non Redundant N Lower than single disk Very high Very high for both read and write Mirroring 1 Mirrored 2N Higher than RAID 2 – 5 but lower than RAID 6 Higher than single disk Up to twice that of a signle disk for read Parallel Access 2 Redundant via Hamming Code N + m Much higher than single disk Highest of all listed alternatives Approximately twice that of a single disk Parallel Access 3 Bit interleaved parity N + 1 Much higher than single disk Highest of all listed alternatives Approximately twice that of a single disk Independent Access 4 Block interleaved parity N + 1 Much higher than single disk Similar to RAID 0 for read, significantly lower than single disk for write Similar to RAID 0 for read, significantly lower than single disk for write Independent Access 5 Block interleaved parity N + 1 Much higher than single disk Similar to RAID 0 for read, lower than single disk for write Similar to RAID 0 for read, generally  lower than single disk for write Independent Access 6 Block interleaved parity N + 2 Highest of all listed alternatives Similar to RAID 0 for read; lower than RAID 5 for write Similar to RAID 0 for read, significantly lower than RAID 5  for write   Read page 215 – 221 for detailed explanation on RAID levels Optical Memory There are a variety of optical-disk systems available. Read through the table on page 222 – 223 Some of the devices include… CD CD-ROM CD-R CD-RW DVD DVD-R DVD-RW Blue-Ray DVD Magnetic Tape Most modern systems use serial recording – data is lade out as a sequence of bits along each track. The typical recording used in serial is referred to as serpentine recording. In this technique when data is being recorded, the first set of bits is recorded along the whole length of the tape. When the end of the tape is reached the heads are repostioned to record a new track, and the tape is again recorded on its whole length, this time in the opposite direction. That process continued back and forth until the tape is full. To increase speed, the read-write head is capable of reading and writing a number of adjacent tracks simultaneously. Data is still recorded serially along individual tracks, but blocks in sequence are stored on adjacent tracks as suggested. A tape drive is a sequential access device. Magnetic tape was the first kind of secondary memory. It is still widely used as the lowest-cost, slowest speed member of the memory hierarchy.

• Failed to install GRUB on a separate '/boot' partition on a fake RAID 0 (12.04LTS)

  - by gerben

  I'm having some problems getting GRUB configured for Ubuntu 12.04LTS on a fake RAID 0. I can either get the GRUB rescue prompt at startup, or just a GRUB prompt but I cannot boot to Ubuntu manually. How can I configure the GRUB to actually use the Ubuntu install? The steps taken: Installing Ubuntu on fake raid The Ubuntu installer cannot install Ubuntu on the drive. After defining the partitions to use it fails with "Error: ???", pressing OK terminates the installer. Therefore, I used GParted to configure the partitions: /dev/mapper/sil_agadaccfacbg : (the RAID configuration, created partition): /dev/mapper/sil_agadaccfacbg1:ext2, 200MiB, (with 'boot' flag) /dev/mapper/sil_agadaccfacbg3:ext2, 67.75GiB, (which will contain Ubuntu) /dev/mapper/sil_agadaccfacbg2:extended, 1.00GiB, (for swap) Contains: /dev/mapper/sil_agadaccfacbg5: unknown Because of the fake-RAID, I already mounted the destination partitions before running the Ubuntu installer: > mkdir /mnt/boot > sudo mount /dev/mapper/sil_agadaccfacbg1 /mnt/boot > mkdir /mnt/ubuntu > sudo mount /dev/mapper/sil_agadaccfacbg3 /mnt/ubuntu In the installer I chose the following partition usage: /dev/mapper/sil_agadaccfacbg1 ext2, mount at /boot (209MB) /dev/mapper/sil_agadaccfacbg3 ext2, mount at / (72751MB) /dev/mapper/sil_agadaccfacbg5 swap Device for boot loader installation: /dev/mapper/sil_agadaccfacbg, linux device-mapper (striped) (74.0GB) This will install Ubuntu, but will fail to install GRUB (it seems to use /dev/sda no matter which one I choose) Installing GRUB with dpkg-reconfigure I followed this guide, but adapted it for two partitions: sudo mount /dev/mapper/sil_agadaccfacbg3 /mnt/ubuntu sudo mount --bind /dev /mnt/ubuntu/dev sudo mount --bind /proc /mnt/ubuntu/proc sudo mount --bind /sys /mnt/ubuntu/sys sudo mount /dev/mapper/sil_agadaccfacbg1 /mnt/boot sudo mount --bind /boot /mnt/boot sudo chroot /mnt/ubuntu dpkg-reconfigure grub-pc However, it does not ask where to install GRUB (I should choose /dev/mapper/sil_agadaccfacbg somewhere..) After reboot I get the GRUB rescue prompt with message no such device Installing GRUB with grub-install After the same mount commands as above, I continued with: > sudo grub-install --root-directory=/mnt/boot /dev/mapper/sil_agadaccfacbg This gives the following message: /usr/sbin/grub-probe: error: cannot find a device for /mnt/boot/boot/grub (is /dev mounted?) It does succeed when mounting just the boot partition : sudo mount /dev/mapper/sil_agadaccfacbg1 /mnt sudo grub-install --root-directory=/mnt/ /dev/mapper/sil_agadaccfacbg This finishes with: Installation finished. No error reported. After reboot I get the GRUB console, with welcome text. Attempting to manually start Ubuntu: ls (hd0) (hd0,msdos3) : (Ubuntu install partition) (hd0,msdos1) : (Ubuntu boot partition) (hd1) (hd1,msdos1) : (Ubuntu live USB) ls (hd0,msdos3)/ contains: - vmlinuz - lib/ - tmp/ - initrd.img - mnt/ - var/ - proc/ - boot/ - root/ - etc/ - run/ - media/ - sbin/ - bin/ - selinux/ - dev/ - srv/ - home/ - sys/ ls (hd0,msdos1)/ contains: -grub/ -boot/ -initrd.img-3.8.0-29-generic -vmlinuz-3.8.0.29-generic -config-3.8 linux (hd0,msdos3)/vmlinuz This returns "error: out of disk" Installing GRUB on Ubuntu partition with grub-install > sudo mount /dev/mapper/sil_agadaccfacbg3 /mnt > sudo grub-install --root-directory=/mnt/ /dev/mapper/sil_agadaccfacbg This finishes with message: > Installation finished. No error reported. After reboot get the message "error: out of disk" and the GRUB rescue prompt. Configuring GRUB with grub-mkconfig Attempting to run grub-mkconfig with different destinations results in the same message: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?). Remarks: Initially I didn't use a separate /boot partition, but the GRUB install then also failed. Because some mention that a small partition at the beginning of the drive is necessary on old machines, I retried with a /boot partition This is a single boot (no other OS's installed/used)

• Need help partitioning when reinstalling Ubuntu 14.04

  - by Chris M.

  I upgraded to 14.04 about a month ago on my HP Mini netbook (about 16 GB hard disk). A few days ago the system crashed (I don't know why but I was using internet at the time). When I restarted the computer, Ubuntu would not load. Instead, I got a message from the BIOS saying Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key I took this to mean that I needed to reinstall 14.04. When I try to reinstall Ubuntu from the USB stick, I choose "Erase disk and install Ubuntu" but then I get a message: Some of the partitions you created are too small. Please make the following partitions at least this large: / 3.3 GB If you do not go back to the partitioner and increase the size of these partitions, the installation may fail. At first I hit Continue to see if it would install anyway, and it gave the message: The attempt to mount a file system with type ext4 in SCSI1 (0,0,0), partition # 1 (sda) at / failed. You may resume partitioning from the partitioning menu. The second time I hit Go Back, and it took me to the following partitioning table: Device Type Mount Point Format Size Used System /dev/sda /dev/sda1 ext4 (checked) 3228 MB Unknown /dev/sda5 swap (not checked) 1063 MB Unknown + - Change New Partition Table... Revert Device for boot loader installation: /dev/sda ATA JM Loader 001 (4.3 GB) At this point I'm not sure what to do. I've never partitioned my hard drive before and I don't want to screw things up. (I'm not particularly tech savvy.) Can you instruct me what I should do. (P.S. I'm afraid the table might not appear as I typed it in.)

• How to fix: Ubuntu 12.04 reboots after loading with elilo

  - by Casey

  I have an HP p6-2120 with CPU: AMD A6-3620 APU with Radeon Graphics RAM: 6GB BIOS: HO2_710.ROM v7.10 [AMI v7.10 4/19/2012] Disk: SATA1 (/dev/sda) - 1 TB (windows) Disk: SATA2 (/dev/sdb) - 1 TB partitioned using "parted -a optimal /dev/sdb" as follows: .. 1049KB 201MB FAT32 boot flag set .. 201MB 60GB ext2 (/) .. 68GB 78GB linux-swap(v1) (swap) .. 78GB 790GB ext4 (/home) .. - rest is "free" space reserved for other purposes (eventually) ubuntu: 12.04.1 LTS [specifically: Release 12.04 (precise) 64-bit] kernel: linux 3.2.0-29-generic I created a bootable EFI USB from the ISO (64-bit) which I downloaded. I can run and install from the USB without any problems. The BIOS is an EFI bios that appears to be capable of booting in either EFI or Legacy mode. Initially, I did the "standard" install with NOTHING on disk2, and let the installer configure everything. The net result of this was that when I started the computer and forced it into "boot" menu mode, it DOES NOT recognize SATA2 as an EFI drive, and when I attempt to "legacy" boot from it, I get the message "ERROR: No Boot Disk has been detected." The "standard" install created one large partition that consumed the entire disk. At that point, I manually partitioned the disk (using sudo parted -a optimal /dev/sdb) as described above. I selected the "other" install, and changed the /dev/sdb1 to "bios_grub", /dev/sdb2 as "/" (ext4), /dev/sdb3 as swap, and /dev/sdb4 as "/home". [Note: fearing that possibly elilo did not recognize ext4, I switched /dev/sdb2 to ext2 and re-insalled] The net result was that the install appeared to trash the /dev/sdb1 partition so that it was NOT readable by anything. I re-formated /dev/sdb1 as FAT32 and set the boot flag. I repeated the install ignoring the messages about no bios_grub partition. After several attempts to get GRUB2 to work, I switched to elilo. I downloaded the most recent version and copied it (elilo-3.14-ia64.efi) to /dev/sdb1/efi/boot/bootx64.efi. (The BIOS boot loader did not recognize it either as elilo-3.14.ia64.efi or as elilo.efi. Based on the advice in one of the web-pages I found, I renamed it to bootx64.efi. This worked.) In that same directory (/efi/boot), I copied the file pointed to the link in /dev/sdb2/vmlinuz to /efi/boot/vmlinuz, and the file pointed to the link in /dev/sdb2/initrd.img to /efi/boot/initrd.img. I created an elilo.conf file as follows: timeout=5000 prompt default=linux-boot image=vmlinuz label=linux-boot read-only initrd=initrd.img root=/dev/sdb2 The /efi/boot directory contains 4 files: bootx64.efi elilo.conf vmlinuz initrd.img When I power-cycle the computer and force the boot menu, drive2 shows up as an EFI bootable drive. When I select it, I get the elilo prompt. Pressing , it appears to load the kernal (I have tried it with verbose=5, and there is a long string of messages with the final one a command line to load the kernel and a series of several dots that fly by) then the screen goes blank, and it reboots the computer. [Note: I have also tried substituting the UUID as found in the /etc/fstab of the installed system for the root directory. This had no effect.] This is a brief synopsis of several nights of fiddling with this. I would deeply appreciate any help you can give.

• Perfect End to a Bad Day

  - by TehGrumpyCoder

  Yesterday's post about A Bad Day at Work actually had an addendum to it. There were apparently a bunch of guys on ice skates last night competing in some sport way the hell and gone over on the other side of the valley, and enough people couldn't live without seeing them that they had all major arteries heading west honked. I mean honked... the traffic guy reported the 101 had 16 miles of backup... yikes. Since I worked downtown for a number of years, my fallback is to cut across the city on surface streets to get to one of my old 'haunts' and just drive it home from there. Of course with the 101 backed up, then I17 would logically be as well, so I kept the news on rather than my Zune and heard where the bad stuff was going North. I popped out on the freeway about 7 miles south of my exit. Got to the exit which is about a mile from the house without killing or maiming me or anyone else. Waited patiently at the light in the inside lane to make a left and go under the freeway proceeding West. The light changed, I had full green, I started through and whoa... I've got someone in a little rat car crossing my bow! A little explanation... I drive a 3/4 ton pickup with a V-10, extended cab and shell on the back. It's not jacked up, but it sits up pretty good and is longer than any parking place I've ever tried to put it into. I consider this truck to be the consolation prize for paying uninsured motorist coverage for 45 years and having Pilar Martinez totally destroy a 3/4 ton Silverado on March 1, 2007 by plowing into me at traffic speed while I was stopped at a light. If you pay for uninsured motorist coverage, ask your insurance agent *exactly* what that means... I bet it's different than what you think it means. But I digress, sorry... So here I am with a car that is shorter from top to road than the hood on my truck, and the driver thought it would be safe to run a red light and see if they could get past me before I got into the lane. The right side of my front bumper was almost into the driver's window when I hit the brakes and wheeled it left. Fortunately for all involved, I saw it soon enough, and pulled into the 2nd lane for making a left to go back South. I looked in my mirror, signalled a move, then moved over behind the yuck in the rat car. I then punched it, and the future hood ornament and I both made it through the next light. I pulled alongside to let her know that she was DEFINITELY Number 1 in my book, and it's a middle-age woman looking at me with a "sorry, it was an accident" show of pouty face and arms held up. Tough $hit lady... that may have worked when you were 18, but it's not working anymore, and it wasn't an accident... you ran a freakin' red light and almost got yourself killed. That just about put a bow on the day... I was home later than usual, pissed off about work stuff, pissed off at traffic, and now that. I ate dinner, watched a little TV, and was asleep about 9:30 exhausted. Hope today is better.

• The best computer ever

  - by Jeff

  (This is a repost from my personal blog… wow… I need to write more technical stuff!) About three years and three months ago, I bought a 17" MacBook Pro, and it turned out to be the best computer I've ever owned. You might think that every computer with better specs is automatically better than the last, but that hasn't been my experience. My first one was a Sony, back in the Pentium III days, and it cost an astonishing $2,500. That was even more ridiculous in 1999 dollars. It had a dial-up modem, and a CD-ROM, built-in! It may have even played DVD's. A few years later I bought an HP, and it ended up being a pile of shit. The power connector inside came loose from the board, and on occasion would even short. In 2005, I bought a Dell, and it wasn't bad. It had a really high resolution screen (complete with dead pixels, a problem in those days), and it was the first laptop I felt I could do real work on. When 2006 rolled around, Apple started making computers with Intel CPU's, and I bought the very first one the week it came out. I used Boot Camp to run Windows. I still have it in its box somewhere, and I used it for three years. The current 17" was new in 2009. The goodness was largely rooted in having a big screen with lots of dots. This computer has been the source of hundreds of blog posts, tens of thousands of lines of code, video and photo editing, and of course, a whole lot of Web surfing. It connected to corpnet at Microsoft, WiFi in Hawaii and has presented many a deck. It has traveled with me tens of thousands of miles. Last year, I put a solid state drive in it, and it was like getting a new computer. I can boot up a Windows 7 VM in about 19 seconds. Having 8 gigs of RAM has always been fantastic. Everything about it has been fast and fun. When new, the battery (when not using VM's) could get as much as 10 hours. I can still do 7 without much trouble. After 460 charge cycles, the battery health is still between 85 and 90%. The only real negative has been the size and weight. It's only an inch thick, but naturally it's pretty big with a 17" screen. You don't get battery life like that without a huge battery, either, so it's heavy. It was never a deal breaker, but sometimes a long haul across a large airport, you know you're carrying it. Today, Apple announced a new, thinner and lighter 15" laptop, with twice the RAM and CPU cores, and four times the screen resolution. It basically handles my size and weight issues while retaining the resolution, and it still costs less than my 17" did. So I ordered one. Three years is an excellent run, but I kind of budgeted for a new workhorse this year anyway. So if you're interested in a 17" MacBook Pro with a Core 2 Duo 2.66 GHz CPU, 8 gigs of RAM and a 320 gig hard drive (sorry, I'm keeping the SSD), I have one to sell. They've apparently discontinued the 17", which is going to piss off the video community. It's in excellent condition, with a few minor scratches, but I take care of my stuff.

• College Ratings via the Federal Government

  - by user9147039

  A few weeks back you might remember news about a higher education rating system proposal from the Obama administration. As I've discussed previously, political and stakeholder pressures to improve outcomes and increase transparency are stronger than ever before. The executive branch proposal is intended to make progress in this area. Quoting from the proposal itself, "The ratings will be based upon such measures as: Access, such as percentage of students receiving Pell grants; Affordability, such as average tuition, scholarships, and loan debt; and Outcomes, such as graduation and transfer rates, graduate earnings, and advanced degrees of college graduates.” This is going to be quite complex, to say the least. Most notably, higher ed is not monolithic. From community and other 2-year colleges, to small private 4-year, to professional schools, to large public research institutions…the many walks of higher ed life are, well, many. Designing a ratings system that doesn't wind up with lots of unintended consequences and collateral damage will be difficult. At best you would end up potentially tarnishing the reputation of certain institutions that were actually performing well against the metrics and outcome measures that make sense in their "context" of education. At worst you could spend a lot of time and resources designing a system that would lose credibility with its "customers". A lot of institutions I work with already have in place systems like the one described above. They are tracking completion rates, completion timeframes, transfers to other institutions, job placement, and salary information. As I talk to these institutions there are several constants worth noting: • Deciding on which metrics to measure is complicated. While employment and salary data are relatively easy to track, qualitative measures are more difficult. How do you quantify the benefit to someone who studies in one field that may not compensate him or her as well as another field but that provides huge personal fulfillment and reward is a difficult measure to quantify? • The data is available but the systems to transform the data into actual information that can be used in meaningful ways are not. Too often in higher ed information is siloed. As such, much of the data that need to be a part of a comprehensive system sit in multiple organizations, oftentimes outside the reach of core IT. • Politics and culture are big barriers. One of the areas that my team and I spend a lot of time talking about with higher ed institutions all over the world is the imperative to optimize for student success. This, like the tracking of the students’ achievement after graduation, requires a level or organizational capacity that does not currently exist. The primary barrier is the culture of "data islands" in higher ed, and the need for leadership to drive out the divisions between departments, schools, colleges, etc. and institute academy-wide analytics and data stewardship initiatives that will enable student success. • Data quality is a very big issue. So many disparate systems exist (some on premise, some "in the cloud") that keep data about "persons" using different means to identify them. Establishing a single source of truth about an individual and his or her data is difficult without some type of data quality policy and tools. Good tools actually exist but are seldom leveraged. Don't misunderstand - I think it's a great idea to drive additional transparency and accountability into the system of higher education. And not just at home, but globally. Students and parents need access to key data to make informed, responsible choices. The tools exist to not only enable this kind of information to be shared but to capture the very metrics stakeholders care most about and in a way that makes sense in the context of a given institution's "place" in the overall higher ed panoply.

• On a BPM Mission with Process Accelerators. Part 1: BPM as an ATV

Their thirst for new processes to improve with BPM makes them explorers in a landscape of opportunities. They have discovered that with BPM the can “go places” they couldn’t reach before. In a way, learning how to generate value with BPM is like adopting a new mean of transportation. Apps are like regular cars: very efficient, but to be used on paved roads: the road/process has been traced, and there are fixed paths to follow to get from “opportunity to quote” or from “quote to cash”. Getting off the road is risky, and laying down new asphalt is slow and expensive. Custom development is like running: you can go virtually anywhere, following any path you like, yet it’s slow, and a lot of sweat. BPM allows you to go “off the beaten path” laid out by packaged apps, yet make fast progress compared to custom development. BPM is therefore more like an All-Terrain Vehicle (ATV): less efficient than a car, but much faster than running, with a powerful enough engine that can get you places. The similarities between BPM and ATVs don’t stop here: you must learn to ride it even if you already know how to drive a car; you can reach places but figuring out the path to your destination is harder. Ultimately, with BPM as with an ATV, you reach places that you thought you could never reach, and you discover new destinations that provide great benefit to you … and that you didn’t even know existed! That’s where the sense of accomplishment that we heard from our BPM customers comes from, as well as the desire to share their experience, or even, as in the case of a County, the willingness to contribute their BPM solutions to help other agencies that face the same challenges. The question we wanted to answer is how can we teach organizations to drive ATV/BPM, thus leading them to deeper success with BPM, while increasing their awareness of the potential for reaching new targets, and finally equip them with the right tools. Like with ATVs, getting from point A to point B is more of a work of art than cruising on the highway by car. There is a lot we can do: after all many sought after destinations are common: someone else has been on the same path before. If only you could learn from their experience …

• Problems with jQuery getJSON using local files in Chrome

  - by Tauren

  I have a very simple test page that uses XHR requests with jQuery's $.getJSON and $.ajax methods. The same page works in some situations and not in others. Specificially, it doesn't work in Chrome on Ubuntu. I'm testing on Ubuntu 9.10 with Chrome 5.0.342.7 beta and Mac OSX 10.6.2 with Chrome 5.0.307.9 beta. It works correctly when files are installed on a web server from both Ubuntu/Chrome and Mac/Chrome (try it out here). It works correctly when files are installed on local hard drive in Mac/Chrome (accessed with file:///...). It FAILS when files are installed on local hard drive in Ubuntu/Chrome (access with file:///...). The small set of 3 files can be downloaded in a tar/gzip file from here: http://issues.tauren.com/testjson/testjson.tgz When it works, the Chrome console will say: XHR finished loading: "http://issues.tauren.com/testjson/data.json". index.html:16Using getJSON index.html:21 Object result: "success" __proto__: Object index.html:22success XHR finished loading: "http://issues.tauren.com/testjson/data.json". index.html:29Using ajax with json dataType index.html:34 Object result: "success" __proto__: Object index.html:35success XHR finished loading: "http://issues.tauren.com/testjson/data.json". index.html:46Using ajax with text dataType index.html:51{"result":"success"} index.html:52undefined When it doesn't work, the Chrome console will show this: index.html:16Using getJSON index.html:21null index.html:22Uncaught TypeError: Cannot read property 'result' of null index.html:29Using ajax with json dataType index.html:34null index.html:35Uncaught TypeError: Cannot read property 'result' of null index.html:46Using ajax with text dataType index.html:51 index.html:52undefined Notice that it doesn't even show the XHR requests, although the success handler is run. I swear this was working previously in Ubuntu/Chrome, and am worried something got messed up. I already uninstalled and reinstalled Chrome, but that didn't help. Can someone try it out locally on your Ubuntu system and tell me if you have any troubles? Note that it seems to be working fine in Firefox.

• System.InvalidOperationException: Failed to map the path '/sharedDrive/Public'

  - by d03boy

  I'm trying to set up a page that will allow users to download files from a shared drive (where the file is actually sent via the page). So far this is what I have. public partial class TestPage : System.Web.UI.Page { protected DirectoryInfo dir; protected FileInfo[] files; protected void Page_Load(object sender, EventArgs e) { dir = new DirectoryInfo(Server.MapPath(@"\\sharedDrive\Public")); files = dir.GetFiles(); } } The aspx page looks kind of like this: <% Response.Write(System.Security.Principal.WindowsIdentity.GetCurrent().Name); %> <ul> <% foreach (System.IO.FileInfo f in files) { Response.Write("<li>" + f.FullName + "</li>"); } %> </ul> When I remove the erroneous parts of the code, the page tells me that the Windows Identity I'm using is my user (which has access to the drive). I don't understand what the problem could be or what it's even complaining about.

• Password Cracking Windows Accounts

  - by Kevin

  At work we have laptops with encrypted harddrives. Most developers here (on occasion I have been guilty of it too) leave their laptops in hibernate mode when they take them home at night. Obviously, Windows (i.e. there is a program running in the background which does it for windows) must have a method to unencrypt the data on the drive, or it wouldn't be able to access it. That being said, I always thought that leaving a windows machine on in hibernate mode in a non-secure place (not at work on a lock) is a security threat, because someone could take the machine, leave it running, hack the windows accounts and use it to encrypt the data and steal the information. When I got to thinking about how I would go about breaking into the windows system without restarting it, I couldn't figure out if it was possible. I know it is possible to write a program to crack windows passwords once you have access to the appropriate file(s). But is it possible to execute a program from a locked Windows system that would do this? I don't know of a way to do it, but I am not a Windows expert. If so, is there a way to prevent it? I don't want to expose security vulnerabilities about how to do it, so I would ask that someone wouldn't post the necessary steps in details, but if someone could say something like "Yes, it's possible the USB drive allows arbitrary execution," that would be great! EDIT: The idea being with the encryption is that you can't reboot the system, because once you do, the disk encryption on the system requires a login before being able to start windows. With the machine being in hibernate, the system owner has already bypassed the encryption for the attacker, leaving windows as the only line of defense to protect the data.

• How do you remove a site from Sharepoint Designer?

  - by xpda

  I would like to use Sharepoint Designer 2007 as an html editor. I have a web site with a lot of files in a folder on my hard drive. I do not want Sharepoint Designer to make a web site out of this. I just want to use Sharepoint Designer to edit the html files, locally. If I ever make a mistake and click on a tool for Sites, such as summary or report, Sharepoint Designer will decide that my folder is now a web site. From that point on, Sharepoint Designer is painfully slow whenever I open a file contained in the folder that Sharepoint decided is my web site, instead of being instantaneous like it was before. I can resolve this situation by renaming the folder containing my web site -- everything gets fast again. I can also fix it by uninstalling and reinstalling Sharepoint Designer. Neither of these is a good solution. Is there a place in Sharepoint Designer, or in application data or the registry that I can kill off the Sharepoint Designer web site that's associated with a folder on my hard drive?

• Publishing my Website to my Local Disk Causes Exceptions to show Paths including my Local Disk

  - by coffeeaddict

  I've published my website many times. But didn't think about this though until I came across this issue. So I decided to publish my WAP project to a local folder on my C drive first. Then used FTP to upload it to my shared host on discountasp.net. I noticed during runtime that the stack trace was referencing that local folder still and erroring out.

• SQL Agent Logon - What is going on?

  - by James Wiseman

  I have a DTSX package that is called from a SQL Agent Job. The DTSX package references a file at a fixed location (e.g. e:\mssql\myfile.txt). On most machines, this location exists, but on some I have to manually map this (which is not a problem - I know a better solution would be to use package conifgurations to dynamically pull the file location, but this is not an option here - and anyway I'd like to understand what is going on) I have set up the agent service to run as a specific user (e.g. myuser) When I log on as this user and map the directory, then run the dtsx package directly, then all goes well. When I run the package through a SQL Agent Job, the file cannot be found. If I add a command line job step to the agent job to map the drive: net use e: \\svr\location Then all works file also. So what is going on in the backgound? How come the SQL Agent user requries the drive mapping even when I am logged in as this user.

• VBScript Catching Erroring Varialble Value

  - by Soren

  I have a VB Script (.vbs file) that is just a simple directory listing of a drive. It will the base of a drive back up script. But when running it as it is below, I am getting a Permission Denied error on some folder. What I need to find is what that folder is so I can figure out what the problem is with the folder. The line that is giving the error is "For Each TempFolder In MoreFolders". So what I am trying to figure out is how to WScript.Echo the current path (objDirectory) if there is an error. I am not sure if it matters much, but just in case, the error that I am getting is Permission Denied 800A0046 on line 12. So some folder, I do not know which one, is not letting me look inside. Set WSShell = WScript.CreateObject("WScript.Shell") Set objFSO = CreateObject ("Scripting.FileSystemObject") Dim FolderArr() FolderCount = 0 TopCopyFrom = "G:\" Sub WorkWithSubFolders(objDirectory) Set MoreFolders = objDirectory.SubFolders 'The next line is where the error occurs (line 12) For Each TempFolder In MoreFolders FolderCount = FolderCount + 1 ReDim Preserve FolderArr(FolderCount) FolderArr(FolderCount) = TempFolder.Path ' WScript.Echo TempFolder.Path WorkWithSubFolders(TempFolder) Next End Sub ReDim Preserve FolderArr(FolderCount) FolderArr(FolderCount) = TopCopyFrom Set objDirectory = objFSO.GetFolder(TopCopyFrom) WorkWithSubFolders(objDirectory) Set objDirectory = Nothing WScript.Echo "FolderCount = " & FolderCount WScript.Sleep 30000 Set objFSO = Nothing Set WSShell = Nothing

• Programmatically modifying a file on Windows Server 2008 (Web Ed.)

  - by Tom

  I have written a .NET 2008 application, incorporating Microsoft.Office.Interop.Excel, that modifies an existing Excel 2007 spreadsheet. It works perfectly on my WinXP development computer. When I upload the app to a Microsoft Web Server 2008, it opens the file and reads from the file, but when the app tries to save the file, it throws this exception: "System.Runtime.InteropServices.COMException (0x800A03EC): 'july2009.xlsx' is read-only. To save a copy, click OK, then give the workbook a new name in the Save As dialog box." The file is NOT read-only, nor is it opened by any other user or app. The app and the Excel file both reside on the D: (data-only) drive. My first instinct was to look at file permissions. When nothing else worked, I literally created a temporary Group, added EVERY user and security entity to it and granted the group full control of the entire D: drive. No luck. Then I tried manually elevating the permission by running my app as administrator. No luck. Finally, I copied the file to my XP development computer and ran the app there. Of course it worked perfectly. Can anyone please tell me how to give my program permission to edit a file on Server 2008? Thanks!

• How do I programmatically create a bootable CD?

  - by Nicholas Flynt

  I'm using a barebones tutorial as the basis for an OS I'm working on, and it seems to be an older tutorial: it has be compiling the kernel down to a floppy image, and then loading it with GRUB. Basically, I still want to use GRUB, but I'd like to have my OS run from a CD instead. The main reason is that I don't actually have a real floppy drive available (I'm testing in VirtualBox currently) and I thus have no way to test my OS on real hardware. I've been poking around on the net, and I can find lots of utilities that create a bootable CD from a floppy image, but these all seem to require an actual floppy drive, plus it's not really what I'm looking for. I'd like to be able to end up with a bootable CD during my make step ideally, without needing to first place the image on a floppy, which seems rather pointless. I guess the easy way to answer this: How do I set up GRUB to read my kernel image from a CD? Will I need a special utility to do this from Windows? (The kernel can't compile itself yet, that's not for a looong while) Thanks!

• return an ArrayList method

  - by Bopeng Liu

  This is a drive method for two other classes. which i posted here http://codereview.stackexchange.com/questions/33148/book-program-with-arraylist I need some help for the private static ArrayList getAuthors(String authors) method. I am kind a beginner. so please help me finish this drive method. or give me some directions. Instruction some of the elements of the allAuthors array contain asterisks “*” between two authors names. The getAuthors method uses this asterisk as a delimiter between names to store them separately in the returned ArrayList of Strings. import java.util.ArrayList; public class LibraryDrive { public static void main(String[] args) { String[] titles = { "The Hobbit", "Acer Dumpling", "A Christmas Carol", "Marley and Me", "Building Java Programs", "Java, How to Program" }; String[] allAuthors = { "Tolkien, J.R.", "Doofus, Robert", "Dickens, Charles", "Remember, SomeoneIdont", "Reges, Stuart*Stepp, Marty", "Deitel, Paul*Deitel, Harvery" }; ArrayList<String> authors = new ArrayList<String>(); ArrayList<Book> books = new ArrayList<Book>(); for (int i = 0; i < titles.length; i++) { authors = getAuthors(allAuthors[i]); Book b = new Book(titles[i], authors); books.add(b); authors.remove(0); } Library lib = new Library(books); System.out.println(lib); lib.sort(); System.out.println(lib); } private static ArrayList<String> getAuthors(String authors) { ArrayList books = new ArrayList<String>(); // need help here. return books; } }

• Cocoa/AppleScript move file

  - by bogdan

  I have a list of file paths and a destination path. I need something (AppleScript, Cocoa) that will move the files from one location to an other. I first tried using the following AppleScript, just to see what happens: set the_folder to (choose folder) tell application "Finder" move selection to the_folder end tell The problem is that it just blindly tries to move a file, nothing like the way Finder actually moves files (i.e. if a file with that name already exists, the AppleScript just throws an error, while Finder would ask you if you want to replace the file). The solution I came up with involved NSFileManager. I won't post the code because it's quite long, but basically I just check if the file already exists before trying to move, and if it exists a NSAlert with Replace/Cancel buttons appear. I have 2 remaining problems: Authorization - if you try to do something to files where you don't have access, the Finder would ask you to authorize. My code just fails... Moving to external drives - when you try to move a file to a different drive, NSFileManager copies the file and then deletes the original. The problem is that NSFileManager doesn't provide anything which I could use to display a progress indicator of what's happening during the copy. Is there anything I could use that is able to move files without these problems? The way I see it, I'm pretty much stuck with checking if the files are writable by the current user and authorize NSFileManager if not (from my understanding of the Authorization Services, this will be quite hard to implement). Oh and, I would also need to check if the destination is on the same drive and if not, implement something with FSCopyObjectAsync so that it shows a progress indicator... Thanks!
