router madness

in an effort to 1) increase my wifi throughput and 2) set up a VPN server, i took the gf's old Linksys WRT54G wifi router and flashed it with ww-drt.

it was an interesting adventure, though not fruitful in the end. i was able to figure out which package to use for the router, but not by using the handy "find my firmware" tool on the site. instead, i crawled through wikis and forums to learn that that tool is out of date and could brick your router. hurrah!

i got as far as getting basic internet and wifi working, with WPA2+AES wifi security. sadly, it did not perform as well as my old Linksys WRT54G router, which still has Linksys firmware on it.

i was not able to get the PPTP VPN working. i went through many, many forum posts and wikis, trying to navigate the inconsistent, out-of-date and contradictory information. i had to call upon old unix skills to telnet into the router and update bourne shell scripts, run sed commands and the like. i took all the bits of info i could find and tried them in all the combinations i could, but still no vpn connectivity.

so i bagged that and set about trying to increase the wifi throughput. comcast internet is coming in at a zippy (for the US) 25 Mbps d/load speed, but over wifi it was 14 at best with the linksys firmware, and 10 at best with dd-wrt. i read through a number of threads about increasing wifi performance (one key parameter made available with dd-wrt is the transmit power of the radio, plus other cool stuff like assigning Tx/Rx to different antennas), but again was met with contradictory information.

each tweak i tried, guided by user recommendations, actually *decreased* performance. i got it all the way down to 3 Mbps. hurray internet!

after undoing most of the recommended tweaks, i was able to get it back up to a reliable 11 Mbps; still not as good as the stock firmware.

so in the end, i punted by putting back the router with the linksys firmware and ordering an asus RTN66U router. i'm hoping the n-band will provide wifi speeds closer to the 25 i'm getting through the modem, plus it comes with vpn capability. i'm reading that not only is the router software open-source, but its extensive configurability was based on open firmwares like dd-wrt and tomato.

now, here's hoping that the year-old threads i'm reading about the vpn issues with the asus are not indicative of an ongoing problem...

IL crosswalk law: good intentions and probably more deaths

some years ago, when commuting to Park Ridge for work, i noticed a curious plastic sign in the middle of a crosswalk. it had a pedestrian symbol, a stop sign symbol, and the text "State law: Traffic must stop for pedestrians in crosswalk."

And for the most part, traffic did stop. It was all very civil.

But i had not heard of this law, and saw no other mention of it. Until recently.

Recently, Chicago has been placing these plastic signs at seemingly random intersections in the city. I've noticed they're not quite as successful as that first one in Park Ridge, but about half the drivers seem to get it.

But Chicago is doing a couple curious things. First, they're not putting them everywhere, and where they don't appear, drivers don't stop. Second, they'll move them about, as if they only have a handful to spread around. So any given intersection may lose its sign, and as before, drivers no longer stop.

This is causing havoc. I'm worried as hell that, as a pedestrian, any given driver may know the law or not. And even if one does slow down or stop to let me cross, who knows if the guy coming the other way -- or the one behind who thinks the first guy is an idiot and whips around to pass -- is going to yield to me?

in fact, as a driver, on Damen last week a couple walked out onto the street right in front of me (which turns out is against the law) without warning. had i been paying just a tad bit less attention, it's quite possible i could have hit them. yes, they were in a crosswalk, but no, this one did not have the temporary plastic sign. imho, the pedestrians were a bit too optimistic about driver behavior.

given the general ignorance of the law, and infrequent signage, nobody knows what to expect anymore at any given intersection whose rules are not already indicated by a stop sign or traffic light.

to make matters even more confusing, the city has been painting new crosswalks here and there, but with different patterns. on the corner near my house (pictured), they've got two different styles going. is it supposed to mean something? as both a pedestrian and a driver, i have no idea what they mean and how my behavior is supposed to change. at least until the plastic sign makes its temporary appearance.

i like the zebra crossings in London. i think it's smart that they're not as prevalent as Every Single Intersection, and doubly smart that they're frequently not at road intersections, so drivers can react to the pedestrians only, and not worry about turning or other vehicles crossing their paths. i think there are far too many crosswalks in Chicago to make this practical, if pedestrians expect to be able to step in front of a speeding car and survive every time.

our automated society

for the gf's birthday, we caught a matinee at a local mega-cinema owned by Regal:

Regal Entertainment Group (NYSE: RGC) operates the largest and most geographically diverse theatre circuit in the United States, consisting of 6,607 screens in 521 theatres in 37 states and the District of Columbia as of October 25, 2012, with over 211 million attendees for the fiscal year ended December 29, 2011 ("fiscal 2011").

gloriously, we were the only two in attendance. i wondered if the movie would not play if they hadn't sold any tickets. and if not, was that all built-in to their computer/ticket system, or did they actually have a human looking in?

on the way out, we asked. we were told that the movies all play automatically, whether there was anyone in the theater or not. (seems like a waste). I also thought about the tissue paper i jammed in my ears, which made the soundtrack merely Quite Loud (next time, i'll be bringing along my sound pressure meter; i fear some of the peaks are in the 110-120 dB range).

so not only do the movies play automatically, i reckon the volume levels are beyond the control of anyone at the facility. same with the dimming lights and the curtain screen that quietly whooshed to a wider aspect after the previews/commercials and before the main feature. the projectors are all digital, so no one needs to operate them (i wonder how they're loaded/configured).

we didn't visit the concession stand, which i'm pretty sure is still staffed by humans. we bought our tickets from a human, but that's obviously un-necessary these days. a human took our tickets, and another wandered into the theater in the middle of the showing (to make sure we weren't disturbing other patrons?).

in all, i think we saw fewer humans -- including patrons -- than there are theaters. granted, it was an off time (Monday 2:45 showing), and this megaplex definitely gets crowded. i reckon Regal has found a way to maximize profit while minimizing payroll.

spicy burgers and homemade pickles

the gf is pickling cucumbers today, after having acquired 20-lbs of cucumbers from our new veggie CSA, Montalbano Farms. i think there are at least 4 pickle varieties planned.

we also opened a jar from her first batch, made at a pickling class a few weeks ago. a little garlicky and a little dilly, but definitely opened up when paired with the burgers i made for lunch.

we're running low on ground beef from our half-cow, so i grabbed a pound we got yesterday from Meadow Haven. added salt, pepper, a bit of ground ancho chile, and some homemade hot sauce given to be by my aunt. then topped with a white cheddar. and a thank you to Ron for the tip about not mashing the burger meat too much (now i barely touch it).

the burgers were the best yet. a tasty outside char and a lovely medium-rare throughout.

refreshing summer drink: hot blueberry custard shake

directions:

1. wait for blueberry season
2. make custard for blueberry ice cream
3. realize, with horror, that you made too much in step 2
4. drink hot
5. (optional) chase with half and half

United Airlines and the opposite of sense

on a recent trip to nyc, i elected to pay $25 to check my first bag, for each leg. i rightly guessed that by the time i boarded, there would be no overhead space left.

on the return, United announced at the gate that the flight was full, and rollerboards would be gate-checked for free. naturally, i do not expect to be refunded my $25. why should i, when my pre-planning helps them to load the plane more quickly and have a better chance at on-time takeoff.

does it not make more sense to charge people for carry-ons, and grant free checking of the first 2 bags? am i correct in thinking that incenting people to reduce what they carry on, rather than incenting them to increase it, will save money? am i correct in thinking that granting passengers that much extra space, and doing away with at least some of the fighting for shared space, will improve the experience for everyone involved?

is the cost of baggage handling really so prohibitive?

what am i missing?

a little credential standardization, please

just a small rant about sites, especially financial ones, enforcing silly rules for usernames and passwords that vary wildly from one site to the next.

some require special characters in passwords, some can't handle them! is my letters and numbers-only password really secure enough to protect my money?

i had a standard 6-character username, which in the past couple years became insufficient for banks. several financial sites required 8-character usernames.

great, now i have to remember which sites are the username exceptions, along with whatever peculiarities the password rules may have.

this week, i made logins for two more sites where i have some investments. one required a 10-character username, but couldn't handle special characters in the password. what security purpose is served with unwieldy usernames? and what kinds of backends do these sites have that the policy is to exclude special chars? injection-prone php servers? doesn't inspire a lot of confidence.
