Linux sticky bit

As a normal user I can’t seem to run the following bash script:

#/bin/bash
date 121001102020

The file permissions are: 4755

The file owner is: root

I would expect to be able to run this as a regular user. What I get is:
date: cannot set date: Operation not permitted

I’d like to force a fixed date as a regular user (to get Flash to work) rather than having to use su and enter a password each time. Sure appreciate any help.

(I tried this in the system rc files too but the VM still forces an updated date.)

Thanks!

bitcoin core – Brother died and I am sole survivor..just found out he has a wallet. How do I go about getting his bit coins I have no info

I have no info..

Without information, you cannot get control of any Bitcoin your brother possessed.

You need some details of his wallet or of his account with a Bitcoin exchange.

How do I retreive

If he looked after his own money in a Bitcoin wallet on a computer or phone, you need to be able to log in to that device and run the wallet program and enter any password he set on the wallet. He may have kept a note of his wallet’s “private key” or its 12, 18 or 24-word “recovery phrase” written down somewhere safe. E.g. on paper or stamped metal in a safe. If so, you can use this information on a different computer to create a new wallet that controls the same money.

If he had an account with a business that looked after his money for him, you’ll need to find out the name of that business and his login details. It is possible you would find some details in his old email messages.

I have death certificate.

That might be of use if his money was in an exchange and you know his account name but not his account password. You or the executor of his estate would need to contact the exchange directly about this.


You will be contacted by people offering to help you. 99% of these will be scammers intending to trick you into trusting them with any details you find, or who will trick you into paying invented recovery fees but who will never give you access to your brother’s money. Be very very careful.

bit manipulation – Are there any languages able to express how different values encoded in some bits of data?

Often, for efficiency reasons, low level languages encode different kind of information in the same set of bits.

  • A simple example is a pointer: the value 0 represents NULL, all other values represent memory addresses.

  • Or floating point numbers (e.g. IEEE 754) can encode decimal values as well as Infinity, -Infinity, +0, -0, NaN etc.

  • Yet other example are UTF8 characters, where the first bit tells us whether the byte is an ASCII character, or the unary-encoded number of bytes the character takes. Even signed integers use the first bit to encod the sign.

Normally values encoded this way are handled by handcrafted pieces of code performing bitwise operations.
But that means that we can’t generalize over it: for instance you can’t express a generic Maybe (aka Optional) type that encodes the Nothing/Empty state on some unused combination of bits.

Are there any languages with a type system able to understand and express how information is stored in the bits at your disposal?

64 bit – What’s the difference between Cinebench and Sysbench?

I’ve read articles about how Sysbench gives Intel a slight benchmarking edge while Cinebench gives AMD and ARM a slight benchmarking edge. I was wondering what difference between Sysbench and Cinebench would result in this difference. I’ve heard that it might have something to do with giving different weights to graphics performance, but I didn’t find any sources that could confirm it. Could someone perhaps shed some light on this?

How can I disable 128 bit ciphers in apache?

I am using this SSL Conf:

SSLCipherSuite ALL:!RSA:!CAMELLIA:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS:!RC4:!SHA1:!SHA256:!SHA384

Please help! I am unable to find any solutions.

When I use ssllabs.com to check my website https://www.ssllabs.com/ssltest/analyze.html?d=www.chicjrajeevalochana.com, my cipher is always <100%. So, I heard that disabling 128 bit ciphers will get me to the full %. And I want to be as secure as possible.
