Outlook / Exchange Error: Network Problems or the Microsoft Exchange Server Computer is Down for Maintenance
There are tons of posts about this subject, but none of them offered the very simple solution that worked for me: Make sure the Microsoft Exchange System Attendant is running on the mailbox server. We had a catastrophic crash of a VM host, on which our Exchange 2013 server was...
Clone a Dynamic Disk to a New SSD in Windows 10
This is partially just for my own reference, so I don’t have to go down this rabbit hole again. (But I hope it helps you, too!) The Situation I wanted to upgrade the LITE-ON 256GB SSD in my trusty ol’ Lenovo X1 Carbon laptop to a snazzy new Samsung 960...
240V is the Standard U.S. Household Voltage (Kinda.)
OK, So I’m Being a Bit Facetious Obviously I and most everyone else knows that the vast majority of American household stuff is powered at 120V. Almost all receptacles and (nearly) all lights in a home are indeed supplied at 120V. But! It’s not as simple as that. So maybe...
Redundant VPN Tunnels via Different ISPs
Intro My friends will tell you that I’m obsessed with redundancy, both in life and in I.T. At home I have two main internet connections, via Altice Optimum (“cable”) and Verizon FiOS. They’re both relatively high bandwidth, and are connected to my two core routers that operate in an active/passive...
RAID HDD TCO Calculator (Total Cost of Ownership)
A while back I created a HDD TCO worksheet showing the relative costs of certain drives in no real context. This spreadsheet aims to calculate the total cost of ownership for a RAID array, which is a much more involved affair. https://docs.google.com/spreadsheets/d/1dM2vO08gmX3VwYyJtTE5D1Gu75TTU-nUW95j1_DVx8c/ That’s a read-only version, but you can easily...
There are tons of posts about this subject, but none of them offered the very simple solution that worked for me: Make sure the Microsoft Exchange System Attendant is running on the mailbox server. We had a catastrophic crash of a VM host, on which our Exchange 2013 server was running as a guest. Everything seemed to come back up just fine, and all Outlook users were back online with Exchange, except for two. One user was running Outlook 2016 like the rest of the org, but one was running Outlook 2007 (don’t ask). They seemed to have nothing in common, but they both were throwing errors that network problems were preventing communication with the Exchange server. I did all … Continue reading
This is partially just for my own reference, so I don’t have to go down this rabbit hole again. (But I hope it helps you, too!) The Situation I wanted to upgrade the LITE-ON 256GB SSD in my trusty ol’ Lenovo X1 Carbon laptop to a snazzy new Samsung 960 EVO 2TB drive. I have a version of Acronis that came with a Crucial (or Kingston?) SSD, which has worked great in the past. The problem? There was a system reserved partition at the very end of the disk, and Acronis therefore would not proportionally scale the OS partition to fill the disk; It would only scale that system reserved partition. In a moment of errant stupidity, I said, “Ah-hah! … Continue reading
OK, So I’m Being a Bit Facetious Obviously I and most everyone else knows that the vast majority of American household stuff is powered at 120V. Almost all receptacles and (nearly) all lights in a home are indeed supplied at 120V. But! It’s not as simple as that. So maybe the video title is a tiny bit of clickbait, but it’s also more or less true. Most Americans do indeed have 240V supplied to their home, and that is the line-to-line voltage. The transformer is rated for 240 Volts with a center tap that happens to be referenced to ground/earth, and it just so happens that the potential difference between the center tap (ground) and either of the two lines … Continue reading

I found a great deal on eBay. A Dell Compellent SC220 chassis filled with 24 x 600GB 10K SAS disks for $350 including shipping. Obviously if you’re reading this years later that will seem like a terrible price, but as of now 600GB SAS drives are selling for about $30 each (used). So it’s roughly $720 worth of drives alone. The SC220 is basically an MD1220 in sheep’s clothing (though sheep are generally naked so who knows), and those are selling for about $120. Like I said, a great deal! But there was one question that needed answering: Did the Dell-branded Compellent HDDs have some kind of special firmware that rendered them useless with a standard RAID or JBOD controller? … Continue reading
myisamchk If you’re reading this, it’s probably because you’re trying to run myisamchk on a large table and you want to set the –sort_buffer_size to some large value. That’s advisable, of course. However, it seems that some versions of MySQL don’t understand a 2-digit value for that parameter. I was trying to do the following: myisamchk -f -r –update-state –key_buffer_size=4G –sort_buffer_size=16G –read_buffer_size=32M –write_buffer_size=32M /var/sql/myisam-temp/mastersitedb/applicants_master_search – recovering (with sort) MyISAM-table ‘/var/sql/myisam-temp/mastersitedb/applicants_master_search’ Data records: 0 – Fixing index 1 myisamchk: error: myisam_sort_buffer_size is too small MyISAM-table ‘/var/sql/myisam-temp/mastersitedb/applicants_master_search’ is not fixed because of errors Try fixing it by using the –safe-recover (-o), the –force (-f) option or by not using the –quick (-q) flag If you’re getting an error like that, try using … Continue reading
Dear “New Media” Companies, Two years ago I decided to take the plunge and purchase a UHD TV. But I thought twice about it, deciding that I would hold off until there was adequate 4K content available. At that time the 4K market was weak. UHD Blu-rays had yet to be released, and other than some YouTube content and perhaps a few shows from your companies, there wasn’t much available. Finally at the cusp of 2018 I decided to make the move. There’s much streaming media currently available in UHD (as you’re obviously aware), as well as a plethora of UHD Blu-rays. So I now have a very nice Sony OLED hooked up to my HTPC. But the sad part … Continue reading
Atypical Post This post isn’t only for you, but also for me. I have roughly sixteen 120V 1300-1500VA UPSes in my basement of various ages. They each take two SLA 12V ~8Ah batteries. As such, I need to replace those batteries periodically. Being a cheap bastard, I don’t buy the branded APC or CyberPower packs, but go for inexpensive generics from eBay or Amazon. In theory there’s no difference, but in practice some cheap batteries are, well, cheap. I’m attempting to figure out which off-brand brands work best. This Log Hence I’m going to start logging battery replacements to get an idea of which brand(s) represent the best value and longevity. This will always be a work in progress, because … Continue reading
The Echo Look I’m working on a full review-type-thing of the Look, but who really cares about that? I’m sure people will want to see the insides of it, though. The most interesting two things on it are an Intel RealSense SR300 module (minus its visible light camera), and what’s basically a full Intel PC motherboard. In fact, here are the main specs: Intel Atom x5-Z8350 (SR2KT) @ 1.44Ghz (1.91Ghz burst) 8GB Samsung eMMC Flash NAND Storage 8GB Elpida LPDDR3 RAM Broadcom 802.11ac + 802.11b/g/a/n + Bluetooth (Not sure of the version) The hardware is fantastically made and well put together, and overall is very clever considering they stuffed all of it into a diminutive cylinder! The Reassembly I did … Continue reading
ZeroFiller (for Windows!) This might be a relatively niche utility, but I figured I’d share it because it might help someone in the same situation. File Version Description ZeroFiller-v0.8-20171023.zip v0.8a2017-10-23 The ZeroFiller executable only (requires .NET 4.5.2) ZeroFiller-src-0.8a-20171023.zip v0.8a2017-10-23 The ZeroFiller source code (requires >= Visual Studio 2017, probably) Backups I run a lot of VMs and I’m a bit obsessed with backups. I do high-level backups (meaning files, DB data, configs, etc.), as well as low-level backups of the actual VM disk images. The raw virtual disks get snapshotted on the host system, then the snapshot’s raw data is backed up using dd, gzip, and rsync. It’s not fancy, and it basically grabs the machine in a crashed state … Continue reading
Welp, they’ve done it again. Any by “they”, I mean people that make poor quality electrical devices. Specifically Yellow Jacket, which is a Woods brand, which is a Coleman Cable brand, which is probably somehow owned by either Warren Buffet or the Koch Brothers.
I got this for $16.22 during an Amazon lighting deal, and even though that’s not a terrible price, the poor quality construction and the basic lie about the materials is what really angers me.
Join me as I disassemble and then curse at this poor excuse for a power strip, in my newest installment of first world problems.
First World Problems I gotta start off by saying that I know that this is an extravagant waste of time and resources. I didn’t make this video because the K575 was slightly annoying, but rather because it baffles me that they became worse at designing coffee machines than before. It’s doubly confounding because Keurig has based their marketing on the K575 being a “2.0” brewer. As in a (supposedly) new-and-improved follow-up to their original line. Yes, it has a couple of advantages over the older B70 Platinum that I used for comparison. However, it seems that they increased the features without increasing the cost. That says to me that they designed these new brewers on a budget. A schizophrenic software … Continue reading
It’s both easy to explain: It’s a costume-party-road-trip-photo-hunt-food-fight.
And it’s rather hard to explain: You form a team, rent a car, buy some eggs, decorate the car, decorate yourselves, and then follow vague clues through random parts of the southwest for 12 to 18 hours. I guess it’s not hard to explain. But it’s hard to put into words why it’s such a damn good idea.
One thing is for certain: It’s nothing like real life.
Anyone can do this. The more people, the more fun it becomes.Sign up now (unless you’re an asshole). If “YOLO” could ever be used for a substantial purpose, it’s this.

This is a bit unusual for this site, but I decided to create a ringtone from a brief clip of audio on The Ricky Gervais Show. I figured I’d share it, in case anyone else wanted this kind of nonsense in their lives. Why? In the episode, Mr. K. Dilkington argues that every noise has been used at least five times. He then goes on to ask why things can’t be made to make a different noise to the ones they make. Ricky insists that things make a noise because the … Continue reading
