Quora And The Merits of Shark Jumping

Like most professionals who give some thought to their online profile, I’ve spent some time on Quora in my fields of interest. I’m not a ninja at it, like Suster and increasingly Ehrenberg, but a man’s got to sleep sometime.

Skype Postmortem: Overloaded Servers and Desktop Bugs Brought Us Down

Skype today published a lengthy postmortem explanation concerning why its service went down for the better part of two days last week.

CIO Lars Rabbe says in a blog post that a set of support servers responsible for Skype instant messaging became overloaded, and as a result sent delayed responses. A bug in the latest Windows version of the Skype desktop software failed to process these delayed responses, causing them to crash. About half of the world’s Skype users who were signed on at the time the problem began were using that version of the software, and of those, about 40 percent crashed. Among them were users whose machines were serving as supernodes. Rabbe says as many as 30 percent of the Skype network’s supernodes were among the crashed machines.

Losing those supernodes increased the load on other still-functioning supernodes, which was compounded by all the crashed Windows users trying to restart their software and get back on the network. He says traffic to these supernodes surged to 100 times normal volume for that time of day.

What he doesn’t go into great detail about was why the instant messaging servers became overloaded in the first place. Was this another bug in the server software? It’s a little unclear from this explanation.

Rabbe says Skype is trying to learn from the incident and has instituted new procedures to try to prevent this sort of thing from happening again. But this can’t help but hurt its reputation as it looks for ways to diversify its base beyond the millions of free users it has and make some actual money.

The whole reason Skype is supposed to work as well as it usually does is the strength and resilience of the network, and the fact that the network gets stronger as more people are signed on to it. To say that two bugs in a strange confluence of events could bring that entire network down raises a lot of fundamental questions about Skype.

Rabbe says an investment program to increase capacity to support paid consumers and enterprise customers is underway and will continue into 2011. I’m betting Skype will speed it up.

Mark Hurd Really Wants to Keep the Jodie Fisher Letter Private

Lawyers for former Hewlett-Packard CEO and now Oracle Co-President Mark Hurd today asked a judge in Delaware to allow him to intervene in a shareholder lawsuit against HP.

Plaintiffs in the lawsuit are seeking records related to Hurd’s departure from HP in August, including a letter that accused him of sexually harassing Jodie Fisher, a sometimes-actress who worked as a contractor for HP. The U.S. Securities and Exchange Commission is also looking into the possibility that Hurd told Fisher about HP’s then-confidential plans to acquire IT services firm EDS.

Hurd has been trying to keep the letter from being made public, and argued to the judge that since it is his personal property, he should be allowed to join the lawsuit as a party to that end. In the motion, Hurd’s lawyers argue that the letter was sent to “achieve private resolution of a potential dispute” between Hurd and Fisher.

Downgrade PSP to version1.5 using PSP battery

Lots of users downgrade their PSP to version 1.5 because they can upgrade their PSP to any version from 1.5. And if you upgrade your PSP to version 3.51, you can play any downloaded games and run any applications. Do you know that you can downgrade your PSP system to version 1.5 all by yourself by turning your PSP battery into a pandora's battery? All you need are an original PSP battery (with more than 50% charge) and a Memory Stick Pro Duo with 1GB memory or above.

I. Get ready (Reformat PSP memory stick)
Before you get started with the downgrade, you need to reformat your PSP memory stick. If you don't know how to reformat it, you can refer to the steps below:
1. Press the HOME button on the bottom left of your PSP.
2. Use the arrow keys to move to the Settings area, then move the up and down keys to go to System Settings.
3. Push the "X" button (or the "O" button, depending on which button is the "Enter" button of your PSP) and scroll to find the "Format Memory Stick" option. Push the "X" button again to select this option.
4. Your PSP will now confirm that you want to reformat the memory stick, choose yes and your PSP will be physically formatted in a few seconds.
To do the downgrade, you also need to download an application pack. After the downloading is finished, what you get will be a compressed application pack named "pandora", decompress it to the root directory of a hard disc, say Disc H. In this "pandora" folder, you can see four folders including mspformat, msinst, battery and installer, and a file named UPDATE.PBP.
Now you are ALL ready to turn your PSP battery to a Pandora's battery and use it to downgrade any PSP!
II.Turn your PSP battery into a padora's battery
Step 1: Logically reformat your PSP Connect your PSP to your computer. And your PSP will be recognized as a new hard disc, say K. Then click Start -> Run, input cmd in the popped up dialog box, and click OK to enter DOS system. Use the below commands one by one to run the mspformat file: Input "H:", and press the "Enter" Key on your keyboard. (Here H is the disc where the "panndora" folder is located) Input "cd pandora" and press the "Enter" Key on your keyboard. Input "cd mspformat" and press the "Enter" Key on your keyboard. Then input "mspformat.exe K" and press the "Enter" Key on your keyboard. (Here K is the name of the disc that your PSP is recognized on your computer.) After these commands, your PSP will be logically reformatted in a minute.



Step 2: Open the recognized PSP hard disc on your computer, create a new folder and name it "PSP", open this "PSP" folder, create a new folder and name it "game". Copy and paste the "installer" folder and the "battery" folder into the "game" folder. Then copy and paste the UPDATE.PBP file to the root directory of the PSP hard disc on your computer.
Step 3: On your PSP, switch to the Game option, press X or O (depending on which is the "Enter" key of your PSP). Go to "installer" and press X or O to run it.



In a few seconds, a file named "msipl.bin" will be created on the root directory of your PSP memory disc. And now, you should take out your memory disc and then put it back in, which seems to be useless but is a very necessary step.
Step 4: Connect to your PSP back to your computer. Then enter DOS system as mentioned in Step 1. Use the below commands one by one to run the mspformat file:
Input "H:", and press the "Enter" Key on your keyboard
Input "cd pandora" and press the "Enter" Key on your keyboard.
Input "cd minst" and press the "Enter" Key on your keyboard.
Then input "msinst.exe K K:\msipl.bin " and press the "Enter" Key on your keyboard. (Here K is the name of the disc that your PSP is recognized on your computer.)
When you see a popped up message asking if you are sure, click "Yes".
Step 5: Go back to your PSP, switch to the Game option, press X or O (depending on which is the "Enter" key of your PSP). Go to "battery" and press X or O to run it, press X or O to OK every popped up message to finish running the battery application.



Now, your pandora's battery has been created!

III. Use the created pandora's battery to downgrade your PSP
After you turn your batter to a PSP downgrade battery (pandora's battery), you can use it to downgrade your PSP by following the instructions below:
Take out your PSP Memory Stick and battery, then put back in your PSP Memory Stick first, and put your battery back in.Turn your PSP power on, when you see three options; select the Downgrade option, your PSP will be downgraded in a very short time and it will be automatically shut down afterwards.Turn your PSP on again, and you will see a blue screen. But no worries, you can just press the O key, and your PSP system is already version 1.5!
Note: The above process will turn your PSP battery to a pandora's battery that can be used for PSP downgrade. But the pandora's battery cannot be used to play PSP games, videos or music. And the process is not reversible. You will need to get an additional PSP battery for regular uses. However, you can use your pandora's battery to downgrade any PSP to version 1.5 or even repair you PSP.

Some problems the new iPod touch users may meet

1. How to change iTunes to recognize the new iPod touch
Some New iPod users may meet the situation that your iTunes can not detect your new iPod nano, iPod touch, or iPod Classic. It should recognize it immediately. If it doesn't, download the latest version of iTunes. The problem will be solved:
1) Re-launch iTunes, with and without your iPod plugged in.
2) With iTunes open, reset your iPod Touch
(here:http://docs.info.apple.com/article.html?artnum=305743 ) Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds until the Apple logo appears.
3) Restart your computer leaving your iPod touch plugged in
Note: If you uninstall iTunes from a computer, it will be uninstalled for all the users. But it will show up again for all users once you re-install it again. Before uninstalling each user should backup his/her playlists so they can bring them back when the re-install is completed.No music for any of the users will be removed by iTunes. It will remain intact where it is saved.

2．'I can't turn on my iPod'
I have a 1st or 2nd generation video iPod (80 gig).
My computer is windows 2000 so I downloaded the windows 2000 iTunes. So I decided to update my iPod, it was updated and it was fine. It ran out of power. Then it won't turn on? I tried to charge it but it just keeps saying please wait such and such. I left it there for like 2 hours already, and still it didn't charge up... Is the problem because I updated my iPod or something else? And when I opened my computer, iTunes asked me if I can format my iPod into windows. I put yes, it didnt do anything.So I have to problems, its not charging.. and its not turning on.
by Ashley :'My friend had this same problem a few years ago.She just left it plugged in to her computer for a few days, waited it out... eventually the problem fixed itself on its own. I'd say just wait it out for a day or two, and if it's still having problems, take it in to your nearest Circuit City or something.”
by Karat :'its the most popular iPod problem. If you drain the battery fully, you're screwed. Basically the battery is down, but the darn thing wont charge unless you connect it to the usb and the usb wont detect it unless it has charge! So please take it to your nearest apple outlet.”
by Kylla :'The one thing you never want to do with an iPod is let it run out of power, not good for it at all :P I've done it a few times but try to avoid it. What you want to do is hold the menu button and the play/pause button at the SAME time and just wait for it. It should restart it. Thats how my iPod works, yours could be different so experiment with the buttons. Try holding perhaps the center button and the play/pause button? or center button and the menu button? Try to see which two buttons will restart it, its bound to work. But hold BOTH of them down at the SAME time with one hand..and be patient, wait for about 10-15 seconds or so. :)”

3. Why does my 30G iPod video always die quickly?
Even when I am just listening to music. It shuts off after about 45 min. And that is a problem because I am going on a plane trip soon and I plan to watch a movie on my iPod, but movies eat your batttery. Does this happen to anyone else???? How can I make the battery life last longer. btw, it is only like a year old.
by dipin :'In an iPod the battery life is different.
it doesnt depend on how old it is rather it depends on how many times you have charged and discharged it.
for increasing the battery life you should fully charge the battery every time you are charging it . and secondly you should never let it discharge completely . put it on charging just before it shows the red signal and disconnect it only when it is fully charged.
sorry to say but now u'll have to get the battery replaced from apple reseller if you want to watch complete movie the battery life as said by apple is 500 complete cycles of charging and discharging”
by sugadoll :'The same thing happened to me. The problem is that your computer can't detect a completly dead iPod, but you need the computer to charge it so your screwed. j/k I solved it by pluging it into my ihome dock that plugs into the wall. So if you have a wall iPod dock or a car one you can charge it enough so that the computer can detect it. Problem solved.
