I had this frustrating experience before on my android phone (HTC MyTouch 3G). This usually happens after powering on the phone after some time, it does not respond to the physical keys like "Send", "back", "home", "menu". The keyboard lock pattern is gone and you just cannot seem to lock the phone and you need to use the dialer application to make a call! The last time this happened, the factory reset fixed it. But it's a pain trying to reinstall all of your apps and settings back on the phone. So this time I was determined to fix this somehow.
I called the customer service and convinced them to ship me a new phone. Which is nice, but I will still need to reinstall all the apps again. I just searched the forums to see if there is a solution and it seems there is! Unfortunately, many people still seem to have the issue, so this hopefully helps someone.
Basically you need to fool your phone to run the setup wizard that is automatically run when you get your phone. Somehow this kicks out the bug that disables these buttons! But there is no way you can find that wizard (maybe it is possible to launch it somehow from the filesystem, but I don't know how to do that). But this is a way to do that:
- Go to android market and search for the application Anycut and install it. (This application allows you add a shortcut to any activity on the home screen, so it is good to have it anyway.) (Or scan this QR code:
- On the home screen, long press and add "Shortcuts" to add to home screen. Choose Anycut from the list.
- Choose Activity and scroll through the long list of activities.
- Select "Setup Wizard". I had three of them in the list, third one worked for me. (Thanks Mr. Murphy). You might want to try all of them. (First one is for enabling Google Location, second for "Backing up settings to google account and third for Initial Setup)
- It will prompt you to edit the name of the shortcut, you can just accept the default and select it from the home screen and complete through all the screens (use the same google account as you are using).
- Your keys should now be magically working!
The problem might be happening because of some hardware issues (bad internal flash?), but its good to know that it's possible to fix it without factory reset.
Here is a quick tip for extracting audio from youtube videos. I assume you have a reasonably recent linux distribution. (Things might work on other operating systems as well as all the applications that I mention below are ported to other operating systems)
Step 1: Download the flash video file from youtube. Either use greasemonkey script or a python script to extract it. (I use the python script way BTW) You can also use the online site VideoDL.org to show you the download link.
Step 2: Use ffmpeg or mplayer to extract audio from the flv file that you just downloaded:
ffmpeg -i f7v9NhmF3SY.flv johny.mp3
mplayer -dumpaudio f7v9NhmF3SY.flv -dumpfile johny.mp3
I keep forgetting some of the functions in excel and it is embarrassing to search for the same things every time.
PERMUT(n, r) = nPr = n! / (n - r)!
COMBIN(n, r) = nCr = n!/((n-r)!r!)
FACT(n) = n! = 1*2*3*...*n
BINOMDIST(s, n, p, cumul) Probability that there will be exactly s successes in n trials, each trial having a success probability of p (cumul = FALSE). If cumul is true it returns the probability that there will be at most s successes in n trials.
I am looking for a flash media player which can play audio/video content in browser. I am currently using del.icio.us's playtagger for now, but it is limited to mp3 only (I had to change the code a little bit to prevent it from adding multiple inclusions - my changed code is here) and it does not allow rewind/forward.
I also looked at this post which suggests using google video player, which would be nice as it could then also play video files, but it consumes a lot of real estate on the pages. There is also this website mentioned which is nicer but that player is bigger than I want too... And it is probably not a fair use as it is undocumented use...
I also checked out the odeo player, which is nice but you need to host the files on odeo, which is a no-no.
Here are my requirements for this with a scorecard for Playtagger and Google:
- Easy to use. No need to add tag soup for each file. (Del.icio.us + Google -)
- Small size on the page (need to collapse the buttons until user clicks on play button) (Del.icio.us + Google -)
- Ability to rewind/fast forward (Del.icio.us - Google +)
- Play different media formats (mp3/wav/ogg/avi/mpeg video, possibly realmedia) (Del.icio.us - Google +)
Any suggestions ?
This post describes the steps that I took to restore an old server which had died some months back.
I had a linux server running debian pretty reliably. It had failed because of a hardware problems (broken power supply). I replaced the power supply and proceeded to make it current with security fixes. But as it happens when you update after a long time, (or it could also be due to my own itch to remove old kernels), I hosed the system. By that I mean that the system was running but somehow all the kernels had been removed (including the current one that I was running!). Anyway, in summary, the system would not boot because there was no kernel to do so.
Step 1: Okay, I thought I will just reinstall it with Ubuntu (which BTW is my new favorite distribution). But the problem was that the machine was using LVM and Ubuntu installer did not recognize the LVM volumes (even though it is documented to do so).
Step 2: So next stop was latest and greatest Knoppix which recognizes LVM. When I booted knoppix, I was able to see all the old partitions and data (70 gigs of legal *cough* songs, audio books and movies). Success!
Step 3: Next step was to chroot into the old root partition and use apt-get to get the kernel package installed back again. I confirmed that there was no kernel-image-* package installed! apt-get update would fail, because procfs was not mounted, so from out of the chroot, mounted the procfs. After that I was able to update the packages, but the install scripts failed because of errors. The specific error was
/dev/null: Permission Denied. I was stumped. The device looked okay and the permissions also were okay (the script runs as root afterall). Upon some search I found out that it is because the default mounts in knoppix do not mount devices (nodev option). Once I fixed that, all things fell right in place.
I created a small form using which you can search the web for unicode devanagari words. It is very cumbersome to actually enter unicode devanagari characters using qwert keyboards, so I have adopted the phonetic transliteration scheme from Manogat website. Do give it a try:
http://amit.chakradeo.net/search/ (Link now removed, please see update below)
Start typing devanagari words phonetically and you will see unicode characters in the input area. When you hit enter, the phrase will be submitted to google.
Update: (2009-07-14) I have taken down my link now, as there are many more effective alternatives to do this. Check out the following pages from google:

http://www.phishtank.com is a new service which aims to help weed out phishing URLs and email addresses using wisdom of the crowds. Users can submit emails/URLs which they suspect of fraud and others can vote if they really are fraudulent or not. I think it is a great concept. There is a REST API using which applications can embed this webservice within them. So for example, there could be a outlook plugin which will display "phishy" email addresses in a special way in order to alert the user immediately. Same for web browsers which can render phishing websites in a special stylesheet. The applications can also add interface for the user to submit suspect pages and email easily without using web browsers.
I checked out the API and it does not feel like it is fully baked! There are interfaces for authorization and checking email/url status and submitting new emails/urls. Some things that stand out immediately are:
- Exclusive use of SSL for the API access.
- Parameter authentication (i.e. including cryptographic digest of all the parameters to ensure that parameters are not changed using man-in-the-middle attack)
- Choice of xml or php output.
The api calling sequence works like this:
- User registers on the web for API access and gets api key and shared secret
- Using the API, application gets a frob (what is behind the name ?) and authorization url using auth.frob.request
- User has to authorize the frob using the authorization url specified in the response. (optionally you can specify callback url which the server will call for authorization, I will need to check this from home when I have access to a server -- the docs are very thin about the mechanism)
- Once authorized, app uses the frob and gets a token for short time API access (30 minutes in my tests) (auth.token.request)
- App can check token status which tells remaining time on token.(auth.token.status)
- App can revoke the token when it is done using it. (auth.token.revoke)
- The APIs for check.url, check.email, submit.url, submit.email then use the token.
I did not understand why there is a need for FROB in this, why can't you just get the token from api key and shared secret ? What problem are they solving by this indirection ?
Anyway, here is the ruby script that I used for testing this... I am planning to turn this into a module, but providing it here for early access...
P.S. the check_url interface is not working, I am getting invalid token error. and the same token can be revoked successfully.
P.P.S. The API uses SSL (no cleartext api available) and ruby's open-uri library insists on checking the server SSL certificate which always fails (probably because signer needs to be trusted by openssl), I had to change it locally to ignore ssl verification in order to proceed.
Update (Oct/12/06): the check.url interface is finally working. For this API, the signature needs to be calculated before escaping the url. I refactored the ruby script a bit to remove redundant code and moved the configuration to a seperate file. I still need to work with the response parser and make it general for all types of responses. XML parsing gets so ugly so fast, it's amazing!
