Compressed or uncompressed for brainwallet?


You have to be very careful when using the word "uncompressed" when talking about media.

Basically ALL digital media is compressed in some way. Audio, or video. No matter what it is, it is compressed in some way. Its intrinsic to converting from analog to digital.

The problem isn't really technical, its lingual.

People think that uncompressed means "nothing done to it" when in reality there really isnt any way you can do this. There is always some kind of compression done when you convert the analog signal coming out of the mic and going into a file...Its essential.

What uncompressed means is very high quality. And different "Uncompressed" codecs do things differently.

I know more about video codecs, so i will base my example in those.

Black Magic (A company that makes video Out Cards) has an Uncompressed Codec. Its very good. Makes Beautiful images.. But its not really "uncompressed". Sure its big. But compare it to a DPX of TIFF image...

The blockchain is the underlying technology that enables the bitcoin cryptocurrency to exist. A foundational component of this technology is its complex cryptosystem. The blockchain cryptosystem relies on public key algorithms based on Elliptic Curve and message digest functions like SHA-256 and RIPEMD-160. When you create a bitcoin wallet, under the hood you are creating an Elliptic Curve key pair based on Secp256k1 curves. The key pair has a private key and a public key. The private key is the one you keep secret and allows you to sign transactions. For example, when you send bitcoins to someone, you are signing this transaction with your private key and then you announce it to the network. The miners will pick up your transaction and verify that the transaction signature is valid and broadcast to the network until enough miners have validated the transaction and thus achieving consensus. The checks and balances of the Blockchain ledger are updated and when consensus is achieved,...

Hi, I was looking in the forum, but it is difficult to find in another language and I have to use a translator.

The issue is to ask a simple question.

When playing games that are best used dolphin compressed or uncompressed?

That some extra benefit for using them uncompressed?

Already thank you very much for your response.

It is difficult to understand you give us examples or screenshots it could be easier

Some dev said it shouldn't be slower compressed... but some user said it did... I haven't noticed a difference but not compared closely either.

My previous blog post, Cache them if you can, suggests that current cache sizes are too small – especially on mobile.

Given this concern about cache size a relevant question is:

If a response is compressed, does the browser save it compressed or uncompressed?

Compression typically reduces responses by 70%. This means that a browser can cache 3x as many compressed responses if they’re saved in their compressed format.

Note that not all responses are compressed. Images make up the largest number of resources but shouldn’t be compressed. On the other hand, HTML documents, scripts, and stylesheets should be compressed and account for 30% of all requests. Being able to save 3x as many of these responses to cache could have a significant impact on cache hit rates.

It’s difficult and time-consuming to determine whether compressed responses are saved in compressed format. I created this Caching Gzip Test page to...

5 doesn't make this terribly clear: choosing a compressed versus an uncompressed address is not choosing between two different versions of the same address, but rather two different addresses based on the same secret exponent. Sending bitcoin to one address will not be accessible by the other, as they are technically independent. With that in mind, we can address your second point first:

Will I see the coins? Of course! You can see everything that happens on the block chain. Would I be able to spend them if I saw them sitting in the other address? No. Unless you have access to the private key for the other address, you cannot spend the coins.

As for the first point, it really depends on whether or not your client supports signing transactions with compressed private keys. Your client will always be able to receive coins at the public address, but it may not be able to process a compressed private key and thus not be able to spend with it.

Here's some...

If you follow Videomaker closely, you've likely seen us use the terms raw video and uncompressed video. We might say “Camera A captures uncompressed video” or “Camera B shoots raw.” Hopefully we've never said “Camera C shoots uncompressed raw video.” While they sound similar, they do mean different things and shouldn't be used interchangeably.

So what's the difference? Raw video is uncompressed, right? Well, it is, and raw video is always uncompressed. However, uncompressed video isn't always raw.

To understand the difference between raw video and uncompressed video, we need to understand how a digital camera captures images.

The first thing that happens is light hits an image sensor which turns that information into data. At this point, there is no video. There is simply data—just a bunch of zeros and ones. That data needs to be processed and interpreted as video before it can be seen. This is done by the image processor: a second chip in the camera. The image...

To mix compressed and uncompressed source files in the same package, override the Word Count Summary property default by setting the msidbFileAttributesCompressed or msidbFileAttributesNoncompressed bit flags on particular files. These bit flags are set in the Attributes column of the File table if the compression state of the file does not match the default specified by the Word Count Summary property.

For example, if the Word Count Summary property has the compressed flag bit set, all files are treated as compressed into a cabinet. Any uncompressed files in the source must include msidbFileAttributesNoncompressed in the Attributes column of the File table. The uncompressed files must be located at the root of the source tree.

If the Word Count Summary property has the uncompressed flag set, files are treated as uncompressed by default and any compressed files must include msidbFileAttributesCompressed in the Attributes column of the File table. All of the compressed...
