How much data can be in a LocalSettings container

In one of my apps, I’m using Dexie (IndexedDb), but it’s actually much slower and more troublesome than I expected it to be, and after some experimentation I’m considering switching to using LocalSettings containers

My first dexie table represents Items and it has about 85,000 rows, with columns Description, ItemNo, ItemCode, Category, Price and ‘DealPrice’

The second table is for barcodes and it has 98,000 rows with columns BarcodeNo, ItemNo and ItemCode

If I use a LocalSettings container for the items and a container for the barcodes, will that be too much data for LocalSettings to handle?

How much is the Vietnam visa fee for US citizens?

I need an answer from an American who used to apply for a visa to Vietnam. According to an article I learned about Visa Vietnam, there are 3 ways to obtain Visa: Get visa at Embassy, Vietnam on arrival visa and Vietnam Evisa.

Fee for Vietnam visa type single one month:

  • Vietnam evisa: $ 44 for all;

  • Vietnam on arrival visa: $ 10 for service and $ 25 for stamping;

  • Vietnam visa at Embassy: $ 80

I feel secure when I have a traditional visa right away, but I am quite far from Embassy and the fee here is high compared to the other two forms. Please validate to help me that the information that the article I read.

When knowing an individual’s plaintext password history, how much information is expected to be gained with a new password? Do we know this?

The premise: Knowing a persons password history should provide information to help when guessing a new password of theirs.

At an extreme end, with a password history of wildcats, wildcats1, then wildcats2, I’d guess there is less than 1 bit of entropy in their next answer.

At the other extreme end, someone with randomly generated passwords would lose no information in their history. From an information-theoretic point of view, I imagine this is something we can estimate using the large amounts of password history data available in the world.

Somewhere in the middle, a history of “wildcats!Reddit”, “crazydogs!Facebook”, “locobirds!Stackexchange” would give me some good ideas for a Twitter password, and would greatly reduce the entropy of their hash. Of course, this would be related to the concept of password strength.

I’m not so well-read on security, but I assume my idea is not unique. Is there a name for this concept? Do we know any real-world values for the amount of information gained / entropy lost?

How much to donate at Hindu temples in India?

At many Indian temples, on entering the inner sanctum, devotees and foreign tourists alike are often met by a priest who will apply a dab of kumkum (vermilion) to your forehead and perhaps “gift” you a jasmine flower… and hang around expectantly holding a donation tray.

What is a suitable amount to donate? This is assuming you’re visiting a temple that does not have entry fees/tickets for tourists — although I’d be keen to hear whether or not this exempts you from paying the priest.

How much can we trust in mathematical software when working with large numbers, and how much memory it needs to work with these numbers?

For example, I want to evaluate the expression:

$ 3^{3^{{3}^{3}}}$

so I used (it’s free, and I don’t own any software), which returned a decimal form of the number above, namely:

$ 1.258014290627491317860390698… × 10^{3638334640024}$

Which is huge. However, for the number below

$ 4^{4^{{4}^{4}}}$

Wolfram can’t return a decimal form, probably because it’s a much larger number and it needs a lot o memory.

Questions: a) How much can we trust that

$ 3^{3^{{3}^{3}}} \approx 1.258014290627491317860390698… × 10^{3638334640024} $

b) how much memory (aproximate) it needs to evaluate

$ 3^{3^{{3}^{3}}}$


$ 4^{4^{{4}^{4}}}$

I’m guessin a lot of terabytes and something that a home computer can’t handle. But for the first number, Wolfram can, and the second number, it can’t. How do we even find how much size we need to calculate these numbers?

It would be nice if someone improved the tags

How Much of Google’s Search Traffic is Left for Anyone But Themselves?

Interesting post on Rand Fishkin’s Spark Toro blog with stats from a third party on how much organic traffic Google sends to sites other than their own.


…for every click on a paid result in Google, there are 11.6 clicks to organic results. SEO is far from dead…

How Much of Google’s Search Traffic is Left for Anyone But Themselves?

After reading the article, what do you think of Rand’s analogy?

How much will studying magic in an academy cost?

Here is why I ask this question:

I want to create a wizard character that goes on the best magic school in the Eberron settings: the Arcanix. But, I want to say in his background that he has a debt of a big amount of golden pieces that he got to pay for his studies.

I wanted to find how much it could cost to study to become a wizard level 1, but I found nothing.

So here am I, with this question: How much will studying magic in an academy cost?
