I just thought I would share an amusing anecdote from my time at Netflix, related to wi-fi networking in our office. Because many devices that support Netflix have built-in wi-fi, we would test streaming with wi-fi connections to ensure that the experience was still satisfactory. Pretty standard stuff.
At one point, though, we ran into a mysterious problem with wi-fi networking on one of our supported device types. Thinking that perhaps there was an issue with the wi-fi adapter on the device, or the signal from the router, someone did a WLAN survey to see how many wi-fi networks were visible from our corner of the office.
It turns out that there were no fewer than 150 access points visible from there. Yes, 150 access points. That’s what happens when you have a huge number of people, working on a huge array of different devices, with different network configurations, and in different working environments.
Of course, this discovery led to more than a few jokes about sterilization, CIA mind control, and space madness.
(It turns out that the root cause of the problem didn’t have anything to do with wi-fi interference — it was actually a firmware bug on the device, which was triggered by a separate firmware update to the wireless access points in our building. Pretty crazy!)

Sandy and I recently decided to get our DNA analyzed through 23andme. The service genotypes DNA from your saliva, which you send to the lab after collecting it in their “spit kit.” After a few weeks, you get access to a set of results containing health and ancestry information for yourself. The presentation is through a fairly slick web app, with what seems to be pretty good documentation and bibliography for the claims that are made, and an easy-to-navigate interface.
The information available is kind of a mix between useful statistical data (risk factors for certain diseases, whether or not you are a carrier for certain diseases, etc.), and what I think of as “science-flavored astrology” (seeing which celebrities share your maternal or paternal haplogroups, or seeing the percentage of neanderthal DNA you possess).
There are a range of health risks for which their data suggests I am statistically at an elevated risk — similarly, there is another set of risks for which I am at decreased risk. These range from type 2 diabetes, to certain types of cancers, to Alzheimer’s. Some of the probabilities allow you to select a particular ethnicity (presumably selecting for a specific experiment or set of experiments whose results back the calculation), which is somewhat problematic or tough to interpret for someone like me from a mixed background. (23andme itself lets you report multiple ethnicities, but source data for certain health risks may only have involved cohorts of a single ethnicity.) Interestingly, the elevated risks for Sandy and I are mostly disjoint, which gives me hope that our daughter will inherit our advantageous traits while skipping our vulnerabilities.
You can also browse a set of “traits”, which are a set of tests on non-disease characteristics. For example, I am apparently 0.13-0.29 times less likely than the average European to develop male pattern baldness — fingers crossed! I also apparently have a genotype that frequently results in not being able to taste certain bitter flavors, which perhaps explains some of my tastes in food and drink.
There’s also an ancestry aspect to the service, which does a bit of analysis to show where your distant ancestors (500+ years ago) came from, and also provides a “relative finder” and family tree builder. You need to specifically allow the “relative finder” to find close relatives (or to be found as a close relative), apparently to reduce the likelihood of unpleasant surprises. This is interesting but I have no particularly close matches currently registered on the service — the closest are estimated as 3rd through 5th cousins.
The cost of the service is fairly modest — it’s now $99. On the one hand, it’s not at the level where I could call it “cheap” — however, given the breadth of information that is obtained from the test, I think nearly everyone would find something interesting or perhaps helpful from getting tested. To look at it in a very simplistic way, if you undertake any sort of successful lifestyle change (prompted by your genotype analysis results), and you wind up living just a few hours longer than you would have otherwise, it’s “worth it.” I also find the idea that this sort of information is now more readily available to the average person really fascinating — I guess I’m more focused on the potentially positive aspects of it, rather than potential privacy and/or insurability problems.
Since we are moving soon, I figured it would be nice to get rid of stuff we don’t need, or that we haven’t touched in years. I had heard about somewhere, so I decided now would be a good time to try it out. I pretty much cleaned out most of my book collection to have it scanned by this service. Fortunately, since we live nearby, I was able to just drive over there and drop the books off, instead of having to send the package to them. I did have to count pages in order to calculate the price — they charge $1 for every 100 pages or fraction thereof, and there are various add-on services like OCR which add to the cost. I did opt for OCR, so the output should be searchable, too.
In a couple of weeks, my stuff should be scanned and available for me to download and read. Hopefully this turns out well!
So I recently got done burning a huge chunk of time finishing Persona 4 GoldenPersona 4 Golden on the Vita (with the “true ending”). I never played Persona 4 when it was originally released, so I figured that it would be a good game to pick up for the Vita. Overall, it’s a stellar example of “better than the sum of its parts.” There’s a lot to like, but I can also level a lot of critiques at the game.
- The story is fairly compelling. That is, for a game, it’s pretty good. It is full of well-worn character stereotypes, along with two bonus dungeons that really feel tacked on to this re-release, but the main story arc is satisfying enough. (Even if the resolution of the main story is telegraphed well in advance.) I guess the best way to describe it would be that it’s like a really, really long after school special.
- There is a pretty solid set of interactions between the two parts of the game. The “high school time management” stuff has consequences for your equipment and powers in the dungeon crawling part of the game, and you’re motivated to do well in both parts of the game.
- The translation and voice acting are really quite good. Humor and nuance are carried through into English, and given the amount of text in the game, this is no small feat. The dialogue fits the characters, and fits the mood of the game very well.
- There is a ton of stuff to unlock and/or complete. You don’t need to do much of it to complete the game, but it’s enjoyable enough that you’ll be motivated to do a lot.
- The dungeon crawling becomes incredibly tedious as the game goes on. The dungeons are nearly all just tile swaps of each other, with few gimmicks or notable differences between them except the level and type of monsters you fight. Boring…
- The bestiary of enemies you fight is truly insane, and really feels like a huge disconnect from the story and theme. And, what’s worse is that nobody ever really comments on it! When a reanimated table is trying to kill you, you think somebody might find it at least a little funny. I realize that these enemies get carried over between games in the series, but it just seems completely out of whack. And none of the “themed” areas of the game have themed enemies, which seems like a missed opportunity.
- The combat system gets quite boring after a while — there aren’t enough twists and sub-systems to sustain 50+ hours of gameplay. The combat basically boils down to: 1) determine elemental weaknesses, 2) spam elemental attacks of that type, 3) perform all-out-attacks, 4) rinse and repeat. It feels like they even removed a little bit of complexity from P3 since I don’t think any creatures in P4 are resilient to all-out-attacks. None of the boss fights really change things up, either — the only variation is that you might need to heal or remove ailments at some point. There are no cases where the standard battle rules are subverted, or you are forced to use unusual aspects of the battle system — there are only a couple of “trick” encounters, and you don’t even need to recognize the trick to prevail.
- Along similar lines, there’s no real incentive or reason to mix up your party — the main character can fill in pretty much any missing powers via judicious use of Personas. I used Yosuke, Chie, and Yukiko for basically the entire game, because they were the highest level characters I had.
- There’s a decent amount of creepitude (Teddie is the #1 offender) and/or blatant fan-service, which just makes me roll my eyes. A lot of the movies in the game fit this description, actually.
- The social link system of the game is broad, but very limited. There aren’t really any meaningful decisions to be made when advancing someone’s social link, and once you complete it, there’s no meaningful interactivity or payoff beyond the dungeon crawling benefits (persona unlocks, battle abilities, etc.). You can’t pick between character development trees, or unlock mutually exclusive abilities, or anything like that. There was some attempt in the re-release to give some flexibility as far as respec’ing yourself and your allies, but it’s not enough (and it takes too long to do so in-game — you have to burn up a chunk of time every time you want to either get the card for a power, or respec one of your allies’ powers).
- You are also really incentivized to be a giant man-whore, in order to unlock all of the battle benefits for each party member. (There are, I think, two points in the game where man-whoring behavior is pointed out, but there are absolutely no consequences.) All of the benefits, like follow-up attacks, ability to withstand mortal wounds, ability to take fatal damage for the main character, and especially all of Rise’s party-wide boosts are ridiculously powerful, and it would be foolish not to unlock everything that you can.
- There are some story bits that are just kind of dropped on the floor, and left unexplored. The presence of Junes in Inaba, the fate of certain characters, Dojima’s story arc, and some of the “school life” stuff is left unresolved or ignored in the last third of the game. This is kind of disappointing, because I feel that the plot or story could be even more engaging with just a bit more effort.
In spite of all of the negativity above, I really enjoyed playing the game. I just think that with some extra polish it could move from “pretty great niche JRPG” to “amazing game that could be recommended to any gamer.” I suppose there’s always next time.
I’m totally done with P4G now, though. The thought of “New Game+” after playing for dozens of hours already is pretty scary…
A few months ago I decided to update my desktop PC to Windows 8. I am somewhat ambivalent about the new Metro/Modern UI, but I figured that I would update anyway just to be on the latest and greatest.
Unfortunately, after I updated, I started experiencing a lot of bizarre blue-screen crashes. At the same time, sometimes my machine would refuse to get through the BIOS startup at all, which would seem to indicate an issue with hardware rather than with the OS. I suspected perhaps that it was an issue with the SSD I had installed a while back (a Crucial M4), because the BIOS startup code would hang on drive detection. I tried updating the firmware for it, but that didn’t seem to do anything. Finally, after a more serious bout of being unable to boot for an extended period of time, I got frustrated and started trying to isolate things further.
I turned off my external Blu-ray writer (an ASUS BW-12D1S-U), and then all of a sudden I was able to boot consistently. I thought that was very strange, and then got to thinking that maybe it was because I had plugged it into one of the front USB 2.0 ports on my case, and maybe that was drawing too much power. The reason I had plugged it in there was that a different USB 3.0 hub that I had bought (a SIIG JU-H60012-S1) had always been kind of flaky, and didn’t seem to work well with Windows 8 — I checked the Device Manager, and it was listed as “Superspeed USB Hub (Non Functional)”, which was kind of off-putting.
It turns out that there is a firmware update for that USB hub that gets it to work correctly with Windows 8 (I’m guessing that may be more of a “gets it to work correctly at all” update). Applying that update allowed the hub to work in Windows 8, and, in turn, allowed me to plug my Blu-ray writer into it (a separately-powered hub) rather than directly to my computer. And (crossing my fingers) that seems to have solved my stability problems so far.
My layman’s guesses as to why the problems initially seemed to be related to Windows 8:
- There might be power-management changes in the USB drivers for Windows 8, that might be changing behavior slightly and triggering problems with my particular setup.
- I might have switched where I plugged the drive in after I upgraded, not realizing that was what was causing the problem to begin with.
- I didn’t use the hub that often before I updated to Windows 8, and didn’t realize that the hub itself could potentially be screwing with the rest of my system.
I’m just glad that everything seems to be working now, and I can soldier on a bit further with my system (which is almost 3 years old now!)…
I recently picked up a Nokia Lumia 920, which I like quite a bit. I just figured I should try out the WordPress app for Windows Phone 8 — I might post more often if I can punch in a quick post or two on my phone!
I have been going through the process of obtaining an apostille certifying the recent birth of my daughter. It is an international means of certifying the origin of a document from another country – in this case, her birth certificate. We need to have this in order for her to obtain her dual citizenship, from Finland. There is a good primer on apostilles, “The ABCs of Apostilles,” available from the Hague Conference on Private International Law. (Note that not every country is a participant in the “Apostille convention,” so check to make sure that the country in question accepts this means of document authentication.)
The process is a bit involved, so I figured that it would be useful to put together a short article describing the steps involved. Note that the steps may vary depending on where you are – in my case, the instructions are tailored for people living in California (and more specifically, Santa Clara County).
- Obtain a certified copy of the birth certificate. Be warned that Google is infested with dozens of companies that try and obfuscate the “normal” government channels for doing this, and rip you off by charging you money to do things that you can take care of yourself. (As an example, one link that I clicked on wanted to charge me $39 as a “retrieval fee,” on top of the normal costs charged by the county. This is an outrageous skimming fee.)
For Santa Clara County, certified copies of the birth certificate (from birth through 1 year of age) are available from the Public Health Department, through the Department of Vital Records. Information can be found here. At the time of writing, the cost was $21.00 per copy.
Birth certificates older than 1 year must be obtained from the Santa Clara County Clerk Recorder’s office. The cost is still $21.00, although if you order them online or with a credit card, additional fees will apply.
- You will then need to have the signatures of the county health officials certified by the clerk recorder’s office. The reason for this is that the California Secretary of State’s notary section cannot certify these signatures – they can only certify a smaller group, from the various county clerks. This will cost an additional $13.
As an aside, I was missing this crucial step, as it is not called out on the California Secretary of State’s Authentications information page, and none of the other government sites I read while researching this really mentioned it. While the SOS page does mention the limitations on what signatures can be authenticated by the Secretary of State, it does not mention that even though the birth certificate is a certified copy, that its signature cannot be authenticated by their office.
- Finally, you can send the certified document to the California Secretary of State’s notary section, along with a $20 check or money order, a self-addressed stamped envelope, and a cover letter indicating the country in which the document will be used. (In our case, that would be Finland.) Information can be found on the Secretary of State’s authentications page. The processing time, as of this writing, is 3-5 business days.
At the end of this process, you should have an apostille indicating that the birth certificate is an authentic document, valid for use in the country you requested.
I was having some issues with spam on my mail server (hMailServer), so I decided to set up SpamAssassin to filter things before they hit my inbox. While hMailServer has some native support for SpamAssassin, I figured I would write up the steps I used to get things running smoothly as a Windows service.
Note that this is on a Windows Server 2003 box – steps may vary for other versions.
- Download and install the Win32 binaries for SpamAssassin from JAM Software. This includes the spamd daemon, but this normally runs as a command-line application. It is better to run it as a Windows service, so it can be launched automatically when the machine reboots, without having to log in and run it manually.
- Install the Windows Server 2003 Resource Kit Tools, if you haven’t done so already. This contains the srvany tool, which can be used to run an application as a service.
- Open a command prompt for the Resource Kit Tools. There’s a shortcut installed with the tools.
- Run instsrv SpamAssassin <path to Resource Kit Tools>\srvany.exe. This will install a new “SpamAssassin” service, linked to the srvany tool.
- Now, open up the registry editor (regedit). Create a new key under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SpamAssassin, called Parameters.
- Under the Parameters key, create a string value called Application. Set the value of this to <SpamAssassin path>\spamd.exe.
- Under the Parameters key, create another string value called AppDirectory. Set the value of this to <SpamAssassin path>.
- Go to the Services administrator tool, and start the new SpamAssassin service you created.
- Now, open up the hMailServer administrator tool, and go to Settings\Anti-spam. Click on the SpamAssassin tab, and check the Use SpamAssassin checkbox. Fill in the appropriate hostname (localhost should be fine, although you can use 127.0.0.1 if that doesn’t work), and check the Use score from SpamAssassin box. Finally, click on the Test… button to test your configuration. If a dialog box shows up with a response from the SpamAssassin service, you’re good to go.
- If not, check to make sure that the service is running, and that the port used (783, by default) is not blocked. Check to see if the port is being used, by running netstat –an and checking to see that something (the spamd daemon) is using TCP port 783. You can also try enabling logging with spamd by creating an AppParameters string value under the registry key mentioned above, and setting it to –s file. This should result in a spamd.log file being created in the same directory as spamd.exe, and the information within might help you debug the issue.
I just spent the last couple of hours discovering that my U-Verse gateway’s DNS server (serving the internal network) decided, for fun, to persist old IP addresses for some of my computers. The end result of this was that, while their external/NATted access was fine, local network services that were reliant on DNS would fail (since those machines had been allocated new IP addresses). So, for example, Windows file sharing would still work, but pinging or trying to use P4 would fail.
I did find the awesomely named post, “The ATT U-verse 2Wire 3800 HGV-B. I am not a fan…” detailing other problems with it. Needless to say, I am not a fan of it either. I got this resolved (by simply locking those machines to the “incorrect” IP reported by DNS — my will to live was figuratively destroyed by this point), but the next time I run into a problem with it, I’m just going to shove another TomatoUSB-powered router behind it (to replace it as a wireless access point, basically), stick it in DMZPlus mode (more info here), and be done with it.
I’m pretty sure this will be one of a million “stories about Apple” that will be going up tonight, prompted by the death today of one of its founders, Steve Jobs. Like many of my peers, the Apple IIe was one of the first computers I ever used, and one that I spent a huge amount of time with in my childhood — mostly playing games, of course, but also some programming and doing other practical things. The Macintosh that my dad later bought, in turn, also saw a lot of usage by me, although curiously my use of it was tilted more towards the practical and less games and programming. (Games because they simply didn’t exist, for the most part, on the Mac. And programming environments were pretty rudimentary for awhile — the development situation on the Mac at the time was definitely not friendly towards, or accessible by, 9-year-old kids.)
Of those two platforms, I would say that their influences were quite different on me. The incredible breadth and depth of games available on the Apple II platform really fanned the flames of my interest in gaming, which I would later go into as a professional career. The Mac, apart from the obvious innovations in user interfaces, introduced me to concepts like hard drives, laser printing (via PostScript), local area networking, WYSIWYG, and desktop publishing (an innovation that has become so ubiquitous that the term isn’t even used any more).
As a game developer, and someone who did some development on pre-OS X Macs, I wound up bearing a bit of a grudge against Apple. Their development environment, lacking protected memory, was incredibly unforgiving in many ways, and killed productivity. And Apple’s haphazard, ramshackle attempts at courting game developers were for the most part insulting, incomplete, and lacked support. I generally stayed away from purchasing Apple products and MacOS for a long time, ending only recently in the iPhone (which is a pretty decent phone).
So, in total, Apple is a company whose products have been incredibly influential not only in the world at large, but to me personally. And when one of its founders kicks the can, I feel obligated to eulogize just a little bit. In parting, I’ll relate an Apple II gaming anecdote that I haven’t written about before:
When we were kids, my brother and I used to love playing a game called Micro League Baseball, on our Apple IIe. It was a baseball simulation game, with somewhat rudimentary graphics, but a wide roster of teams, and the ability to play head-to-head. The multi-player mode was hot-seat — for each pitch, the player whose team was batting would select an option, and then the player whose team was in the field would select an option. Since the options could include baseball trickery like stealing a base, or pitching out, the person who was not entering their option would look away from the screen and keyboard and cover their eyes. This was to prevent the gaming equivalent of stealing signs.
Our rivalry was quite intense, and it was quite a big deal to us to triumph in these games. (We didn’t really consider the relative strengths of teams we were using, apart from the ’27 Yankees being mega-powerful.) So I wound up doing something that was both smart and dumb. The smart part: I realized that the hollow case and keyboard design of the Apple IIe was such that key presses had distinct timbres to them — ones that could be distinguished quite easily, with a little practice. I quickly learned that I could steal signs and know exactly what my brother was doing, even though my hands were covering my eyes in adherence to the “rules.” If he pressed ’3′ to steal a base, or ’4′ to hit-and-run, I would know about it in advance. The key noises were so distinct that there was basically zero chance of making a mistake.
The dumb part: I took too frequent advantage of this, and he got suspicious after about the sixth time that I called for a pitchout and happened to catch him stealing bases. I had to ‘fess up to my little trick.
I can’t remember if covering our ears, too, became part of playing the game, or if the other person had to leave the room, to ensure fairness and a level playing field.
