Can’t Change Critical Battery Level in Windows 7

battery So with the heavy rainstorms we’ve been getting these pass few days, I’ve been having quite a few brown outs. Everything’s fine though since my computers are all backed by UPSes. However I do noticed that my HTPC always seems to hibernate whenever these brown outs occur. I checked the battery and it was at 99-100%. So I went into the power settings and noticed that the critical battery level action was set to hibernate and the critical battery level was set to 98%. I tried changing it to 10%, but the setting would revert back to 98% immediately after trying to apply changes.

I did a search and found the following 2 threads:

I tried to do what a few suggested such as changing my group policy for reserve battery notification, changing my permissions settings for power schemes in the registry, and a few others, but they all failed to work. The only thing that worked was running the powercfg.exe tool.

powercfg.exe -setdcvalueindex 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c e73a048d-bf27-4f12-9731-8b2076e8891f 9a66d8d7-4ff7-4ef9-b5a2-5a326ca2a469 20

The 2 things you need to change are 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c (power scheme GUID) and 20 (what percentage to set it to). To locate your power scheme GUIDs, open registry editor (regedit.exe) and go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes. The keys (i.e. folders) underneath that location are your GUIDs. I believe the GUID above is for the High Performance power scheme.

Here’s the command to set the Balanced power scheme to have a critical battery level of 10%:
powercfg.exe -setdcvalueindex 381b4222-f694-41f0-9685-ff5bb260df2e e73a048d-bf27-4f12-9731-8b2076e8891f 9a66d8d7-4ff7-4ef9-b5a2-5a326ca2a469 10

Happiness can’t be described by a visible color

It’s been a long time since I posted about an anime series. There hasn’t been much released for the past few seasons that really stood out , but I’m really enjoying Bakuman. From Wikipedia:

The series follows talented artist Moritaka Mashiro and aspiring writer Akito Takagi, two ninth grade boys who wish to become mangaka.

I really enjoy the OP: Blue Bird by Kobukuro

Lyrics:

青空飛び交う Blue Bird
あの鳥が見えますか?
幸せはいつも 見えない Color 感じている
Your love

心配ごとばかりが 積もる春の空を
見上げて うつむいて
また顔を上げてる
この街で 見つけるって決めた自分
無くしちゃいけないものを 胸に

Your love
青空飛び交う Blue Bird
あの鳥が見えますか?
幸せはいつも 見えない Color 感じている
Your love
(Your love)

English Translation (provided by gg):

Can you see the blue birds,
fluttering through the blue sky?
Happiness can’t be described by a visible color, but I can feel
Your love

Every worry floats up to and fills the spring sky
I look up, look down,
and find myself looking back up at the sky
I swore I’d find myself in this town
I tuck away all my important things into my heart for safekeeping

Your love
Can you see the blue birds,
fluttering through the blue sky?
Happiness can’t be described by a visible color, but I can feel
Your love
(Your love)

The way 無くしちゃいけないものを 胸に was sung triggered my memory and reminded me of One more time, One more chance by Yamazaki Masayoshi which I first heard from 5 Centimeters Per Second.

Thanksgiving Trip

bonsai This Thanksgiving trip was rather hard to plan, but I was determined. I really wanted some time away and this trip did not disappoint.

First, there was timing. I had been planning this trip for about 2 months, first inquiring about my sister’s plans for Thanksgiving. When I found out that DC was very close to Durham, NC, I decided I’ll go visit Derek as I had promised years ago. However, work got really busy and for those who know me, I tend to procrastinate a lot. I also had a friend visiting me the weekend before Thanksgiving, so that added additional constraints. After coordinating with my sister and Derek, what should’ve been planned months ago, was only finalized a little over a week before my trip.

Second, being someone mindful of money, flying anywhere during Thanksgiving has always been painful. Apparently $650 total to fly from Seattle to Durham to DC and back is actually a decent price given this was during Thanksgiving.

Durham

My sister is currently getting her masters at Duke. I figured since I hardly get to see my little sister these days, this would be a good time. Plus it gave me an excuse to travel. Durham is a pretty quiet town, but that could be because I went during Thanksgiving and all the Duke students have gone home. The Duke campus was small, but was really pretty and used a lot of old architecture (I don’t know from which period). They also had a really beautiful botanical garden.

We went and saw Harry Potter 7, something about the deathly hallows. The movie was fun and the acting has definitely improved, but I was never really a big fan of Harry Potter and I guess the movie didn’t affect me much. It was enjoyable otherwise.

For Thanksgiving, we were invited to some other engineering student group’s party and had a rather swell time. They had tons of food, too much in fact, but I guess Thanksgiving is all about abundance and overeating. Met some interesting people there.

On one of the other days, we went and checked out Falls Lake, about 40 minutes NE of Durham. The lake was pretty, but we sort of got lost hiking and trust me, it’s not fun trying to find your way back when the sun’s setting. We managed to get lost several times, trying to look for the little white dots on trees that identified the way back. After a couple mis-turns, we finally made our way out of the forest.

Washington D.C.

Did you know for people who live in DC, you put Washington as your city and DC (or District of Columbia) as your state?

For those who saw my Facebook status earlier, you knew I was extremely fond of their subway system. I wouldn’t say it was as good as Hong Kong’s octopus system, but it was really up there in convenience and usability. I was flying into Baltimore and Derek had sent me his spare keys along with a SmarTrip card several days before I flew out. The SmarTrip card is similar to Seattle’s Orca card or Hong Kong’s Octopus card where you can preload it with money and use it for any public transportation.

The 2nd day I was there, I visited a couple of the Smithsonian museums. Did you know all the Smithsonian museums are free? In fact I was told there were only 3 museums in all of DC that actually charged an entrance fee. These are not your dinky little museums, but world-class museums. I got to check out the Gallery of Art, Natural History, Air and Space, and Portrait Gallery. Due to time constraints, I had to briefly go through them and even then each museum took about 2-3hrs to complete. My favorite was the Natural History museum. While browsing through it, I had wished I could’ve visited here as a kid as I’m sure I would’ve enjoyed it much more. The thing I really liked about the Natural History museum is that you get to touch everything. Bones, rocks, … I mean with the museum’s target audience of kids of all ages, they were prepared for this. The Air and Space museum was really cool too, but it reminded me a lot of Boeing’s Museum of Flight in Seattle and maybe that’s why I was not as impressed.

Apparently in order to tour the White House, you have to request like 6 months in advance. The White House was also a lot smaller than I had imagined and less grandeur (from the outside). The Capitol Building gives tours every 15 or 30 minutes. Derek mention that we could try and get a private tour from either my senator or representative. Unfortunately I forgot the names of either of my senators, but for some odd reason I remember California’s. I did remember my rep was Dave Reichart. We located his office in the directory. The people there were very nice. Unfortunately a private tour required 24hr notice in advance, but they were able to give us gallery passes to visit the House of Representative gallery. When the tour started, we were told they were still in session, but they must’ve ended sometime during our tour as we only got to see an empty gallery with a few pages.

The monuments were also really cool. Did you know that the stretch of grass between the Capitol and Lincoln’s memorial is called the mall. When Derek first mentioned the mall, I was a bit confused as I thought he was referring to a bunch of retail stores along that stretch of land. But nope, the mall is what they call that area. I didn’t get to check out all the monuments and memorials as by the time I got to the Vietnam Memorial, the sun was setting. I really wanted to see the statue they put up for the Iwojima soldiers (after watching Clint Eastwood’s Flags of Our Fathers), but apparently that wasn’t located at the WWII memorial. Derek says that statue is located in some circle, but we never got a chance to visit it.

We also did a Segway tour of the city and that was extremely fun. It was my first time on the Segway, but it was rather intuitive to learn. It was scary when I first got on it, but by the end of the tour, I was doing pretty well. I contemplated for a bit about getting my own Segway, but ultimately decided that it’s not for me, especially given where I lived. Maybe if I lived in the city or if I lived closer to work.

There is so much more to say, so much more I saw, so much more I wanted to do, but I won’t bore you with the details. For my Facebook friends, do check out the photo album (if it’s not up yet, it’ll be up shortly).

I was surprised with how much there is to do in DC. I’ve been there for 3 full days, and wished I could have stayed for at least a full week. That just means there’s a next visit. 😀

Echofon for Firefox – Authentication failed. Incorrect signature

For the past few days, Echofon for Firefox on my main desktop started acting funning, popping up an error dialog every second: Authentication failed. Incorrect signature

The only way to actually use Firefox was to quickly log off Twitter in between those error dialogs.

My laptop which also had Echofon did not experience this issue, so it doesn’t appear to be account related nor a global problem. I decided I would try to resolve the issue when I got home.

When I got home, I tried removing and re-adding my Twitter accounts from Echofon, revoking the OAuth access on Twitter’s website, and even clearing my cache and cookies without any success. Those darn annoying error dialogs always came back. A quick search online didn’t result in any quick solution either. Most people saw this error on their iPhone/iPad and associated it with some timing/clock issue. There were a few tweets that said they had the same issue on Firefox, but resolved it by removing and re-adding the account.

As a last measure, I decided to uninstall the addon and re-install it. Apparently that fixed it. Not sure if this solution will work for everyone, but worth a try.

Update: I believe I’ve found the culprit. This has to do with https. I was using HTTPS-Everywhere and the fact that HTTPS-Everywhere was enabled, but Echofon was told not to use SSL for Twitter made things go wacky. Go into Echofon preferences and enable “Use SSL for all requests”. Afterwards, I still had to uninstall and re-install the add-on for the error messages to go away. Maybe restarting Firefox would’ve worked too. Ben has confirmed below in the comments that you’ll just need to restart Firefox and the issue should go away. For folks hitting this issue, give it a try and let me know if it worked for you.

Rock Band 3

Rock Band 3 Wireless Pro-Drum and Pro-Cymbals Kit So I’ve finally got my own copy of Rock Band 3 (thanks to Perry and Sathana). But I’ve also been playing it previously over at Chad’s and also at Ryan’s place.

Here’s my initial impressions.

Songs

I wasn’t actually that impressed with the new song list. There were a few I recognized, but I think it’s gotten to the point where most of the popular songs have already been released and the ones that aren’t either are in the works of being released or the rights holder aren’t cooperating.

Existing Song Upgrades
No one was quite sure how’d upgrades would work, but with the recent release of Bon Jovi’s Greatest Hits 12-track DLC, Harmonix has announced the following:

Hey gang,

Sorry for the confusion surrounding the DLC announcement this week. The information I posted earlier may not have been the most helpful, partially because it wasn’t entirely correct. A lot has happened in the last two hours. The long and short of it is that we’re going to have new RB3 files that add keys and harmonies as well as add-on content that enables Pro Guitar and Pro Bass. The new information is that the add-ons for Pro G/B should be available for both the new RB3 file and your existing file.

To be clearer, this means there will be three files you can download in the future for Legacy DLC songs where Pro Guitar/Pro Bass is being made available:

· The new “RB3 Version” of a song, including traditional GBDV, keys (pro and regular) and harmony vocals
· A “Pro Guitar/Pro Bass” upgrade for that “RB3 Version”, allowing you to have the whole experience
· A “Pro Guitar/Pro Bass” upgrade for legacy “RB2 era DLC”. This will skip Keys and Harmonies being added (those are only in the “RB3 Version”, but allow you to purchase the Pro Guitar/Bass add-on without rebuying the core song file.

To reiterate, if you stick with your RB2 legacy track and want to upgrade to pro guitar/bass – you will not have access to Keys, Pro Keys or harmony vocals. If you want that latter content, you need to purchase the “RB3 Version” of the file.

As for the Bon Jovi tracks coming out next week, you’ll currently only be able to get the Pro Guitar / Bass upgrades for the RB3 Versions of the tracks, but moving forward you should see Pro Guitar/Bass upgrade options for legacy re-releases. We’ll update this thread when we have a timeline for those add-ons. Sorry again for the mix up, and I’ll continue to clarify in this thread as more questions pop up.

In other words, people who purchased the original DLC are screwed if they want to get harmony + keyboard support. They’ll have to rebuy the RB3 version at full retail price of $2, rendering the previously downloaded DLC pretty much useless.

Gameplay

The gameplay had a bunch of enhancements which were greatly appreciated:

  • When someone failed, you can continue playing the song in No Fail mode
  • You can change difficulty in the middle of a song
  • It now shows you the difficulty of your instrument for the chosen song when you’re selecting the difficulty for your instrument
  • All instrument mode allows 7 people to play at the same time: guitar, bass, drum, keys, + 3 vocals
  • Song selection has a lot more filters
  • Song rating/recommendation will allow me to play songs I prefer and never show me songs I dislike
  • All songs are unlocked from the get go. No need to play career mode to unlock songs. I think there are still some Rock Band 2 songs I haven’t unlocked yet
  • When the game is paused or settings are changed in the middle of a song, it rewinds back 5 seconds and lets players prepare themselves
  • Players can easily sign in, drop out, and swap instruments

Changes I think would make the game better:

  • Don’t show or gray out modes that aren’t supported (e.g. Don’t allow me to select Harmony if there’s no harmony part)
  • Show the vocal score even if they’re not “considered” 1 of the 4 players

Keyboard

I was originally excited about the keyboard since I used to play the piano. However, I found the Pro Keys experience very lacking and complicated. Maybe because I’m more used to reading sheet music than little notes scrolling down the screen. I also haven’t gone through the training yet (if they have one), so maybe it’ll get better afterwards…

When I first started playing, I treated the keyboard like a computer keyboard. The screen only shows 10 white keys at a time, so armed with 2 hands and 10 fingers, I placed each digit on a separate white key. Unfortunately this made playing the keyboard very boring and I felt like I was typing instead of playing. I was told to actually use one hand instead of 2, which made a lot more sense as I believe the notes they tell you to play are really chords.

A big difference between this and the plastic guitars is that you can hold down notes on the plastic guitar and they’ll tell you which buttons you’re holding. This won’t count against you as long as you’re not strumming. However that option is not available for the keyboard and being disoriented with where my hands are when I’m always staring at the TV screen, I found myself wishing the screen would tell me which keys my fingers were touching, since it does count against you if you push down a key.

Drums

Honestly, the drums is now my favorite instrument. I can’t believe how much more fun adding cymbals would be! Rock Band 3 now supports Pro Drums which actually differentiates between when to hit the cymbals and when to hit the pads. I originally was going to just keep using my original RB1 drum set, but after finding out how much fun cymbals were, I went and purchased the RB3 drum set. $130 was a bit high, but they were just so fun!

The new drum set also supports 2 pedals. Unfortunately (or maybe fortunately), I’m not skilled enough to need to utilize 2 pedals just quite yet.

Vocals

All songs allows 3 vocalists now in both Solo and Harmony mode, which is pretty cool. What’s even cooler is that 3 people can sing a song in Solo mode on expert and as long as one of the singer is on key for each section, you can ace it. We were getting so many 5 gold stars Friday night.

Guitar

Not much to say here yet since neither pro guitars have been released yet. The toy one with 102 buttons will be released on 11/16, retailing at $150. The one I want is the real electric guitar that supports Rock Band 3, but unfortunately that’ll be released in March 2011 and even more unfortunately at a retail price of $280.

I don’t know if I want to wait till March before trying Pro Guitar, but do I really want to spend ~$450 for 2 Rock Band 3 guitars?
