  • Black Friday!

    Being the crass consumerist I am, the only thing I’m buying today is this.

    For me.

    Because I want it.

    (Meanwhile, Mrs wizardpc is braving the hordes shopping for actual Christmas presents. I’m at home with lilwizard and tacticaldog.)

  • My month without a cell phone.

    My parents got the family’s first cell phone in around 1994. I got a pager in 1996 around the same time I got my driver’s license (so my parents could randomly ask me where I was). In 1998, I bought my first cell phone for me, but gave it up shortly after that mostly because I didn’t use it enough to justify the cost difference between the phone and the pager. In 1999 I got another one after my mother reported me missing because she called my dorm room at 7pm on a Friday night and I didn’t answer. True story. Cops were not pleased.

    I’ve had at least one cell phone on me at all times since then. I think I’ve had three or four numbers, but a few years ago I signed up for Google Voice and I’ve been using that number ever since. More on why this is important in a minute.

    A few things happened this summer that made me think about ditching my $75/mo cell phone entirely. First, there was the realization that I don’t really use the phone part. A review of my bill shows an average of around 30 minutes per month.

    Secondly, I heard about a family in Canada living like it’s 1986. I’ve had a cell phone for a long time, but I do, in fact, remember the days without them. Somehow society survived and things got done. Surely it wouldn’t be very hard to go back to that, right?

    Lastly, there’s that whole thing with tracking the movements of every American based on cell tower records. If you’d told someone in 1985 that twenty years later not only would they willingly keep a tracking device on them at all times, but that they’d gladly pay for the privilege, you would’ve been thrown in the nut house. Now they just call you a racist. 😀

    So I decided to do an experiment. For the month of October, I simulated not having a cell phone. Simulated, mind you. I still have a contract on this thing until July so I’ve got to pay for it until at least then.

    Google Voice is neat in that you can tell it which phones your GV number forwards to based on a schedule. So, Monday through Friday from 730AM until 530PM, my Google Voice number calls my desk at the office. It always calls my cell phone number. I also get texts through my GV number which can be picked up through the android app, the web site, or I can set them up to go to an email account. During the experiment period, I left the cellphone redirection turned on, but decided to just not answer my phone unless I was at home or at the office. No one knows my actual cell number, so I know that all calls come through GV. I also only made calls either at home or at the office.

    What I mostly use my cellphone for is mobile data. That’s easy enough to shut off. They all have wifi on them, too, so I’d just have to cope with that somehow.

    Now, some of you are thinking this is silly from a cost-savings standpoint because if I used my cell phone at home, that means I’ll need to get a landline. That’s where this little box comes in:

    That’s an OBi100 VoIP Telephone Adapter and Voice Service Bridge. It’s a $40 box that plugs into your router on one side and a standard telephone on the other. It connects to Google Voice and will ring when someone calls your GV number, and will use Google Voice to make outgoing calls. It’s a one time fee that’s half my monthly cell phone bill. (Caveat: No 911)

    The idea was that if my test went well, I’d buy one of these and cancel my plan when my contract is up. Instead of a cell phone, I’d carry a wifi-only tablet like a Nexus 7 or perhaps even an iPad mini.

    I’d get voicemail and text notifications when I was on wifi, which is available practically everywhere now. I’m not so important as to be needed immediately to anyone and any “emergency” at work would have to wait for me to get home to my laptop anyway.

    So on October 1st, I turned off mobile data and wondered what the hell I was doing.

    Turns out….I can totally live without it. The results of my experiment were very positive. I only even received two calls while I was out–one from a dog groomer who accidentally called my cellphone instead of my wife’s, and one from my brother (while I was driving and wouldn’t have been able to answer anyway).

    The mobile data was a little harder. I “cheated” once when I foolishly tried to find an address in a confusing part of town without looking at a map before I left. I did have to temporarily turn on data in order to find out how to get to where I was going. This would be easily remedied by either looking at a map beforehand or by buying a dedicated GPS. I could also, perhaps, get a GPS App for the tablet.

    I did get in trouble once with mrs wizardpc for not effectively communicating travel plans, but that was early in the month and taken as a lesson learned. Easy fix.

    I also noticed that I didn’t get Google Voice notifications if I happened to be off a network when the text or voicemail originally came. Unlike the email applications on Android, you’d have to go into the GV app to see if you missed anything. This can be “fixed” by having GV send notifications to email.

    There were also benefits! I actually had conversations with people while I was out instead of reading news feeds! CRAZY! I paid more attention to my wife and son while in public! INSANITY!

    All in all the experiment went very well, and I’d be all over dumping my cell phone when my contract is up.

    Except.

    That new position I just accepted may require me to be highly available. I’ve got six months to see.

  • Aaaaand we’re back

    You know what’s awesome?

    When your web host turns off your database completely, then sends you an email asking you to troubleshoot a problem that requires you getting into the database.

    Better still is when, after complaining for 24 hours that you can’t get into the database to troubleshoot, you get a snarky “oh, it was obviously this, so I fixed it for you” reply. How would I know something that was obvious if I can’t see it at all?

    If I hadn’t prepaid for the rest of the year less than a week ago, I’d be switching hosts right now.

    Grrrr…….

  • My 2 cents on the recent scandals over privacy…

    …is actually summed up by one of my local buddies:

    “To everyone who ever thought I was kidding or just spinning some conspiracy tales for kicks when I repeatedly said “The government is sniffing basically all your communications online”…

    F@$k you people.”

    Seriously.  Next time large portions of the IT community tells you that there’s a high likelihood that the government is snooping through x communication (which it’s been doing for years… yes, this includes before the W.), maybe you’ll believe them.  It’s not like there haven’t been sightings of men in suits showing up to datacenters and having NOC analysts install servers with no labels for years or anything, or documented cases of cell phones going into “listen” mode.

    Remember… just because you’re paranoid doesn’t mean that they’re not really out to get you.

  • Deal Alert: Half off hosting at HostGator

    For the next 12 hours. The coupon code should auto-populate.

    I’ve been very happy with Hostgator.

  • You know you’re a geek when…

    Earlier this week, I stopped by Wizard’s place to pick up the wedding gifts that were left at the reception.  I mentioned to Wizard and his wife that one of my groomsmen bought me a BlendTec.

    His wife cocked her head.

    He started laughing in an evil way.

    Yeah… Wizard and I were geeking out over a kitchen appliance.

    And just in case you don’t know why:

  • APCO-25 Scanner for $25

    Remember the Air Traffic Control post from earlier? Yeah, well, it turns out you can use the same cheap dongle to pick up APCO-25 transmissions.

    APCO-25 is the protocol that most public safety radios use. Scanners that are cable of intercepting these transmissions have been around for over ten years, but they still cost over $400. Even used they’re not very cheap.

    I think this will be my lunchtime project.

  • Public Service Announcement: Blog under attack (probably yours, too)

    I have a WordPress Plugin called Limit Login Attempts that I’ve been running for a while. It basically gives a quick and easy way to limit brute force attempts on your WordPress site by blocking IPs that have invalid logins. It’s pretty configurable for as simple as it is, and one of the things it will do is email you if an IP has been blocked.

    My email has been blowing up for the last three days.

    This happened in December and January, too. That’s about the same time as a couple pro-gun blogs were hacked and people were wondering if it was some sort of conspiracy. It’s not. It’s just script kiddies.

    So do two things today–today–if you run a WordPress site:

    1. Install Limit Login Attempts
    2. Rename the default ‘admin’ account to something else (and not to your domain name)

    I’d say 95% of my invalid login attempts use the admin account. The other 5% use “gunscarstech”, “gunscarstech.com”, “qwerty”, or “administrator” to log in. During the last attack, I added all the IPs to my global deny list at my hosting provider. You might want to do the same.

  • Help me pick an HTPC replacement

    Late last year, I built up a home theater PC to replace one that had died. It’s got a very pretty case designed to fit in with audio equipment (protip: if you’ve got young kids or large dogs, don’t hook up the power button to the motherboard. Use the reset switch instead). I put a Blu Ray drive, about 6 TB of storage, and a massive amount of RAM in it. It’s a hoss of a box, and I’m not going to be getting rid of it.

    The new house we bought has a great media room. It’s already wired for sound and has surround speakers in the ceiling. The HTPC would look great on the built-in media rack.

    Unfortunately, the media room is a converted attic space. It’s not connected to the central HVAC in any way. Instead, it’s got a 13 year old PTHP that only has “on” and “not on” as options. They’re kinda spendy to run, and spendy to replace with newer computer controlled models. What that means is that this room will only be climate-controlled when we’re using it, which probably tops out at 2 hours a day.

    Having an always-on server in that kind of situation is bad. I imagine that the room will get to probably 110F in the summer, before you add the waste heat that electronics produce.  I need some sort of set-top box that can do the following:

    • 7.1 audio out, via either optical or over HDMI
    • Handle a variety of video media in 1080p over DLNA or SMB, or run PLEX or XBMC natively.
    • Not get killed by frequent power cycling

    That last one is there because I’m probably going to put all my stuff on a switched outlet and power that guy off when we’re not using it.

    We have a Logitech Revue we’re using in the bedroom now. It’s okay, but it’s discontinued and underpowered.

    The Roku 3 looks like it meets all my criteria (PLEX has a Roku Channel or whatever it’s called)

    The VIZIO Co-Star looks like it has promise, too only does 5.1 sound, so it’s out. I can’t find anything definitive about the Sony NSZ-GS7. We won’t be getting cable at the new place, so most of Google TV’s features are wasted.

    A co-worker just got this and based on his experience, it’s probably not going to meet my needs.

    I haven’t considered any Blu-ray players with network features. Should I?

    What other boxes should I consider?
