I mostly ask questions. I am curious. I like to listen.

justlearning··on Facebook Privacy Scanner is launched
would it be long before facebook comes out with their privacy-blocking tool. They may be anticipating many tools with these features, so doing accordingly?

as a thought game; I foresee facebook coming up with their claim-n-search-your-privacy app, which they would use to strengthen the privacy game. :)

justlearning··on Closures in Java 7: Not Likely
" yet the decisions are made behind closed doors without any transparency"

care to explain who are these decision makers? Given the JSR and other process, curious to know who makes these hidden decisions.

justlearning··on What Is Your Dream Job?
you sir, have balls of steel.

could you comment on how things have changed for you over the years? I matched your dream job with patio11's comment : "I think I've got my dream job, but three years ago I said the same thing about the last job, and three years prior I said the same thing about the job before that, so your guess is as good as mine what my dream job will be three years from now."

justlearning··on Tips for Successful Self-Learning
Most user groups that I know of are purely for "networking" or to push for a sale of the latest book. But sure- a meetup like the one for clojure in bay area/NY might be enlightening.
justlearning··on Tips for Successful Self-Learning
"The longest path is the shortest and the shortest path is the longest"

back when i was in school and onwards in the academic world, it was always said aloud that the quicker you grasp, the intelligent you were. A lot of students(i perceive - even now) were in rush to prove that they understood - many a times getting to the end of the book before understanding the basics. The momentary appalaud of "well said" and "hurray!" turned out to be a disease - a disease of skimming thru and finding the answers. This got into an habbit and now well embedded in my approach to even outside books. 20 years (outside school) and still counting on the skimming the book[most recently, I picked up a Math book (Intro to Analysis- as suggested Brad's earlier post)]. Struggling thru is a small part of the battle; mind plays the depression game while I try to search for a notation (the greek for complement of a set), while I don't give in as I used to, nowadays it plays the second game of age-"35 years and you don't know 'xyz'!". So yes, my the shortest path has been so long that I have not been able to put an end to it. </end-self-humiliation>

"avoid isolation"

would anyone suggest how to get by this? I work in the enterprise world, where the likes are 9-5/fix-the-bug-save-my-arse. I haven't met anyone whom I could ask about a notation or even discuss about this. I am shy to meet people (read- fearful).few people I did try to ask usually have the repulsive smirky grin. I looked for user groups in the local area (seattle-at present), but didn't find any. It would be awesome if someone tells me this proof of A-intersection-B-intersection-C is going to help in XYZ.

justlearning··on SEC Charges Goldman Sachs With Fraud
would anyone know what would be the fall out from these charges?
justlearning··on Obama administration wanted warrantless access rights to most US email
how so? if I may ask.

Living in the US, I accept the claim that not many get together to say "No". Compare to Asian/European countries where the slightest rift creates huge protests. To cite UK as an example, we always hear British Airways going on strikes(not saying it's a good/bad thing); When was the last time we heard such a thing in the US? I often bring this up in conversations and a common argument thrown at me is that US is an individualistic society - neighbors are strangers to each other. Not all are interested in the big picture to change things. The common man in the US, lured by the media is content in accepting stories on the face value. I have this friend who listens to the radio archives of 60s/70s and often cites "Weather Underground" as an example of changing face of US.

could you provide some cases where in the last 20 years you see "US as a great example of society which dares to stand up and say "No!""

I found this OS by opensuse very similar (not sure what to call it, as it is mentioned that it is an OS around the chrome browser and not affliated to Google)

justlearning··on Ask HN: Please review my website
I downloaded a worksheet and got a file without extension(named:download); I renamed the file to .pdf and opens fine. Would be better if I get a file name of worksheet-type.pdf

I also want to add - it would be nice to see the target age of kids based on the selections or select worksheets based on age, narrowing down to particular type.

fyi- the layout on the pdf is clean (and very kid friendly)

justlearning··on Ask HN: Speedreading - myth vs reality? your thoughts.

Thank you. These are the kind of notes I am looking for.

justlearning··on Upgrade your career
"They’re the elite of the elite of the best programmers out there. They’re the people who participate in Stack Overflow..."

participating in SO makes you elite? Although, there are many convincing real case scenarios discussed by few (perhaps fit for 'elite' label), they are overshadowed by the majority - the badge-gatherers.

What I found (mostly) in SO is more of karmaholics, copying/pasting info from the web. Imho, it is more of a human-enabled search engine for your questions - you get a compiled list of filtered result for your questions, instead of you filtering google results.

justlearning··on Review: AT&T 3G MicroCell
If I hadn't noticed the OP was the author of the article, I would have shouted foul play - in the wake of the at&t-verizon battle with 3G. The article is well written enough for me to remark as a viral ploy by at&t to get back to customers. (I didn't know of the 3G micro cell until I read this article; I assumed that this is a new device released)

justlearning··on Lessons from Rackspace's downtime
I received this email an hour back from Rackspace:

At approximately 12:29am CST this morning, our Dallas - Fort Worth (DFW) data center experienced a power disruption, and consequently an interruption of our services. The power disruption was the result of issues during a maintenance effort that was scheduled and expected to be non-impacting.

This summer our DFW facility had power issues, and as a result, we invested significant resources to improve all aspects of our power systems. Last night, during one of these steps, we encountered issues and had a brief loss in power. The power disruption was approximately 5 minutes in duration. Despite this short power disruption, many customers experienced downtime that was significantly longer. Since the power disruption hit the core of many of our cloud services, recovery of full operations required more effort than simple recovery of power. The experience you had last night is not acceptable to us.

Here is what we know about the events:

· The scheduled maintenance was planned to occur from 12:05am - 6:05am CST in our DFW data center. This maintenance is part of a preventative maintenance schedule for several PDUs in UPS Cluster G at the DFW datacenter. The PDUs were down for a total of 5 minutes before power was restored. At approximately 12:29am CST, all PDUs behind UPS Cluster G lost power.

· Although the power outage was very brief (5 minutes), it forced a hard re-boot to occur on a portion of our cloud infrastructure. As our engineers worked to bring hardware back online, we experienced several unforeseen hardware failures. Further complicating our recovery effort, the incident also created internal DNS issues, which caused additional delays. With that said, the vast majority of cloud customers affected by this outage had service restored within one hour's time (many in as little as five minutes); however, depending upon the service, a few customers experienced service interruptions for up to few hours.

Here is how we plan to deal with it:

· We have invested massively in the DFW facility to ensure it delivers at a level you expect from Rackspace - despite last night, we feel very good about our plan and have high confidence in the DFW facility - clearly we have to prove it.

· We are reviewing our maintenance notifications - we typically do not share information on expected non-impacting events, but clearly we need to ensure we calibrate these events and are fully transparent.

· We are reviewing our procedures and systems for quickly resuming cloud operations when an unexpected event like this occurs - unexpected events will happen, our job is to minimize their impacts.

We live by high standards and clearly have not lived up to them. We welcome any feedback. If you would like a call from me, or anyone on our senior team to discuss these issues personally, please reply with a phone number.

We have work to do to earn back your trust. We will not rest until we have.

justlearning··on Ask HN: what's stopping you from launching?
oddly enough for me - losing interest in the project. Once it's out there, I want to work on something else.
justlearning··on Ask HN: Wrist Pain
I do the following to prevent wrist/shoulder pain.

* keep the hand from elbow to your wrist on the same surface.(if you use a laptop on a table, your wrists are placed higher on the laptop, that's ok.) The key is make sure your elbow/shoulder doesn't move, while you type. This is guaranteed if you rest your elbow on the same surface as your wrist.

* When placed on a table, don't keep your keyboard away from your chest - keep it at an arms length(almost). Once you have found your chair's relative position to table, stretch your arms towards the monitor and place them on the table (placing the elbows first) - place your keyboard in the area where your fingers landed(wrist pad helps)

* Surely helps, if you can forego the laptop keyboard and move to a regular keyboard.

* most keyboards have a "lift" option at the backside- in my experience, I had some pain when I kept the keyboard flat. The lifted keyboard in conjunction with the wrist pad worked fine for me (took few days)

* Never, Never - use laptop (or wireless keyboards) on your lap, pillow etc or places that prompt your shoulder movement.

* Never, Never lift your wrists or elbow while typing?

* (my most effective weapon against pain) - Never, Never use the mouse keypad. Don't touch it. I have disabled mine and use the mouse all the time (again the elbow rest on the table rule applies)

* (edit) work out: swimming helped me.

PS: use the keyboard as you would use a pen.The pain/symptoms of using a pen "abnormally" are similar to pain inflicted by a keyboard.

public places like airport and other places where you don't get a table and cannot rest a mouse, I prefer to read a book, rather than code with hunched,lifted shoulders. It has helped me so far.

justlearning··on Is the Exercise Cool-Down Really Necessary?
Accoding to http://www.nytimes.com/2009/06/02/health/02well.html?_r=2... , cooling(as in taking it slow) in marathons helps with the fainting/passing out.

Wasn't there this story of a 40+ european guy winning grueling competitions based on sheer stamina than performance.It was a story on Nytimes, couldn't find it.

justlearning··on What problems does Google Wave solve?
I didn't find anything new in this article.

But to have a few use-cases, I found this lifehacker article better (http://lifehacker.com/5381219/google-waves-best-use-cases) (it is a crowdsourced collection from users on how they would use google wave, rather than one person speculating on various uses).

The use-case from the air traffic controller seems to be the best - as if wave was an app made for traffic controllers!

justlearning··on Answers.OnStartups.com -- StackOverflow for startups
i can relate to that - with logging with openid here in HN. I had to post an "ask hn" to catch attention of pg - who resolved it. I couldn't make head or tail of what was happening and strongly assumed that clickpass was at fault. Then pg said he had to fix some code.
justlearning··on Answers.OnStartups.com -- StackOverflow for startups
I am genuinely curious - why are you (and some others) against openid? (apart from the trust factor)
