Store CheckOut Lanes

Wednesday, June 24th, 2009

This post was motivated by a recent experience at a local grocery store, although the experience can be had at just about any large store. Every store I have been to has either numbered or lettered checkout lanes. Some stores also have a set of lanes dedicated to self-checkout. If you visit a store frequently, you probably already know which checkout clerks to avoid, but wouldn’t it be great if problem customers could be avoided also? In order achieve this I propose that stores replace the simple number/letter labels on their checkout lanes with descriptive labels. Here is my list …

“Ultra Express Lane” for the Self-Important Terminal Type-A Personalities: This lane is for people who are obviously more important than you or I and who do not deserve to wait in line with common folk. This lane exists but is never open. Its sole purpose is to attract these customers to the store in the hope that the lane might be open. If it were open, it would only allow one customer at a time – no line allowed. The light at the register indicating whether the lane is open or not would be turned on until one of THEM approached the register. The light would then be turned out until the transaction was completed and the customer has left.

“I Do Not Begin to Write a Check Until I See the Total” Lane: At least this is the abbreviated title which has a subtitle “and then balance my checkbook before I hand the check to the clerk”. These folks often add to the misery of those behind them because they do not get their personal identification out of the bottom of their purse/wallet until asked to do so. For whatever reason, they will not fill out anything on the check beforehand – the store name, date, or signature. I can spot these types pretty accurately, I’ve developed a stereotype that generates some false positives, but never traps me behind a false negative. The mere existence of the personalities gives rise to the following lane.

“I Frequently Jump to Between Checkouts Hoping the New One Will Move Faster” Lane: These folks are never happy, but are not as full of themselves as those in the Ultra Express lane. They will jump from lane to lane on a whim. They also tend not to actually enter the physical lane between the magazines, candy, and junk-toy displays that leads to the register in the hopes that a new register might open that they could pounce on. They also tend not to put their items on the conveyor belt until they begin checking out.

Lane for the “Technically Challenged”: These folks always seem to have trouble making payment. They never use cash and pay with credit or debit cards which never seem to work. They know all of the tricks, rubbing the stripe on the back with their finger or piece of clothing, wrapping the card in a plastic shopping bag, changing the speed of the swipe, etc. If they make it past the swipe stage, they probably need to find a piece of paper in their purse/wallet that has their pin number on it which they either can’t quickly find or invariably mis-key the first try at the keypad.

The “I Always Question the Price of at Least One Item” Lane: There is just something about these folks that cause scanners to misread the bar-code or the store product price databases to become corrupt. If those failures don’t occur, they seem to bring along out of date store ads or expired coupons – just in case. These folks usually cause the entire lane of customers behind them to become, at least temporarily, one of the other types of customer.

The “People on Cell Phones” Lane: They start out in line talking, for all to hear, about things that should be kept private. At the register, the clerk must guide them through every step of making payment via hand signals or semaphore flags. It is as though they have never bought anything before – the part of their brain still functioning in our reality probably hasn’t the capacity to remember how transactions work.

“I’m Actually Making Multiple Separate Purchases” Lane: I get burned by this one too often. At first it looks like they are going to by 10 items, but you soon find out that will be achieved through at least 3 separate transactions: one for themselves, one for mom, and one for some other relative or neighbor. They  do mean well, but they need their own lane.

The “I Can’t Count” Express Lane: These lanes always have an item limit of 10, 20, or sometimes 30. Some folks simply can’t count, have inventive ways to group several items into one abstract (I was going to say logical but …) item, or they are really Type-A’s who’ve found the Ultra Express lane closed again. Quite simply, these folks should be spanked – HARD.

I’ve probably missed a few, but this should be a good start.

SSD for MSI Wind

Friday, June 19th, 2009

Just a quick note on replacing the 7200RPM HD in my Wind with an OCZ SSD. Again the backup/restore using Acronis True Image Home 2009 went quickly and flawlessly. Formatting the 120GB SSD with NTFS took 140 seconds. Boot time of the Wind using a fast Scorpion drive took exactly 30 seconds, 10 of which were spent while the BIOS did its thing. Booting with the OCZ Vertex SSD took 23 seconds. When I first booted with the SSD, I thought something horrible had gone wrong. The fan came on and then the entire system went completely silent. Nary a peep nor hum. Only when the login screen appeared moments later did I realize that this total silence was now normal. Very nice.

After using my MSI Wind to run the observatory for a while I found out about this tiny little 1.6GHz Atom-based Windows PC. Doing a little research into its size and other specs, I bought one. The reasons? It will fit inside my AP 900GTO mount, it has 6 USB 2.0 ports, and is fast enough to run the mount, autoguide, manage a filter wheel, and operate my camera. My hope is to monitor observatory ops from inside the house during those cold winter or bug-ridden summer nights. Placing the computer so close to the equipment will significantly reduce the usual tangle of cables associated with digital astrophotography.

One challenge I face is to get Remote Desktop Server running on this system. It came with Window$ XP Home SP3. I have a spare XP Pro license, but I can’t upgrade directly from SP3 (Thanks Micro$oft). So, I’m going to fake it and force RDP to run on Home – or at least try before taking the normal path. I have not tested a headless boot of the Fit-PC2, sans KVM, yet as RDP is required. I do have a fall back position where I put a Keyboard, Video, & Mouse in the observatory at the end of long cable runs.

Since the temperature extremes out in the observatory can be more than you might want to expose a computer to, I plan to swap out the 160GB HD in the Fit-PC2 for a 30GB SSD. 30GB should be plenty for everything I do except for planetary and lunar imaging. For that I have a Sager NP9850 laptop on order with three 320GB 7200 RPM HDs in a RAID-0 configuration, but that is a topic for a future post. I’ll have a fair amount of testing to do, the wireless network throughput out into the middle of my back yard in particular.

For those considering the Fit-PC2, here are a couple of initial impressions. It IS small. Build quality seems quite good. I did manage to crash the system once and that will be something I will monitor closely and followup with a more detailed review. You can hear the HD (it was sitting right in front of me during testing, however). The HDMI to DVI adapter cable terminates in a female DVI, so you need a regular male-to-male DVI cable to hook it up to a monitor. Personally, I would have liked a short cable that I could use to directly connect the Fit to monitor, at least initially. I suppose there will be those that can make good use of the supplied cable – folks who intend to use this as a media center. If I need to use a monitor in the observatory, the supplied adapter cable will be replaced by a long HDMI to DVI cable. The power supply brick is small and the cables are pretty short – outlet to Fit is just a hair over 6′ with the brick 2′ from the outlet. It is a standard cable going from the outlet to the brick, so you probably already have a longer cable in your possession.
