I ask because I think Technomancers do something similiar by becoming biological PANs, and some of their Echoes seem to function through manipulating their nervous system as well.
How can this be re-written. somehow not able to make it right. In case statement Then and ELSE are same would like to change it to single statement.
SELECT t.status_id status_id, ( CASE WHEN t .status_id NOT IN (SELECT status_id FROM firm_return WHERE enabled = ‘D’ and firm_id=t.firm_id)
THEN (cl.category_code + ‘-‘ + s.status_name) ELSE cl.category_code + ‘-‘ + s.status_name END) AS status_type FROM bla bla
We are developing an app, aprox 50k RPM read, 1k RPM write, it ask via key and get a JSON. The search is always made by key. I’m inclined to use one MySQL 8 table with a Id field and JSON field with innodb. Seems simple, cheap and fast accessing by index. Each index can have n rows (30 max), total size of table less than 100gb. Response time is important, I think 2-10ms are achievable on MySQL. The other, more expensive options that I have are DynamoDB and ElasticSearh (can’t use another tool). Can’t find a comparison for this use case to help me know if I’m in the correct path. Do you see any cons of using MySql or I’m missing something? Thanks!!
I would like to ensure that my titles are entered in Title Case. I would prefer to do this from the editor, before it is saved to the database, rather than altering what is displayed, or modifying existing titles.
I asked this question. The answer is YES.
But I’m still not sure – in such a case (i.e. a trigger for reaction being another reaction) – which reaction is resolved first, the triggered one or the triggering one?
Does the readied action interrupt someone else’s reaction that triggered it? Is there a possibility of a chain of such consecutively triggering and consecutively interrupted reactions?
I have a Bernoulli equation (attached below). So this is need to be converted to ODE. I tried to solve it by a separation of variables but I could not. Can anyone help me with the code for this, please?
If you are a B2B company [US], you may collect data on your clients as well as your clients’ customers. For example, let’s say the only thing you need to collect is your clients’ customers’ names.
In the case that your company has a data leak and the individuals’ names are shared with an unauthorized third party, (I believe) you have an obligation to inform someone.
What is the standard practice? Do you directly email the individual and say their information was leaked? Or do you give your client (a business) a list of the client’s whose data was impacted and let them reach out to the impacted clients.
In the case of emailing the impacted clients directly, what if you do not collect their contact information, and have no way to contact them?
Real world example: my personal data was leaked by a B2B software company that I had never heard of. I was contacted by the software company directly as well as their client who I had used the services of. Was it the responsibility of the B2B software company to collect my email in case they needed to contact me directly?
Correct me if I am wrong, please.
I understand that 2FA (MFA) increases account security in case an attacker obtains a password which might be possible via various ways, e.g. phishing, database breach, brute-force, etc..
However, if the 2FA device is compromised (full system control) which can also be the very same device then 2FA is broken. It’s not as likely as opposed to only using a password but conceptually this is true.
Do hardware security keys protect against compromised devices? I read that the private key cannot be extracted from those devices. I think about protecting my ssh logins with a FIDO2 key. Taking ssh as an example, I would imagine that on a compromised device the ssh handshake and key exchange can be intercepted and the Fido2 key can be used for malicious things.
Additionally: Fido2 protects against phishing by storing the website it is setup to authenticate with. Does FIDO2 and openssh also additionally implement host key verification or doesn’t it matter because FIDO2 with openssh is already asymmetric encryption and thus not vulnerable to MitM attacks?
I am working with this code:
function strange (list a[0..n-1] of integers such that abs(a[i]) ≤ n for every 0 ≤ i ≤ n - 1, list b[0..2n] of zeroes) for i ← 0 to n - 1 do a[i] ← a[i] + n for i ← 0 to n - 1 do for j ← 0 to abs(a[i] - 1) do b[j] ← b[j] + 1 return b
I am trying to figure out the worst running time for the code above and so far I’m guessing that the first for loop will run n times, but not sure how to prove this. For the second and third for loop, I’m unsure how to approach this. If possible, could someone help me solve this?
In CLRS the author said
"Technically, it is an abuse to say that the running time of insertion sort is $ O(n^2)$ , since for a given $ n$ , the actual running time varies, depending on the particular input of size $ n$ . When we say “the running time is $ O(n^2)$ ,” we mean that there is a function $ f(n)$ that is $ O(n^2)$ such that for any value of $ n$ , no matter what particular input of size $ n$ is chosen, the running time on that input is bounded from above by the value $ f(n)$ . Equivalently, we mean that the worst-case running time is $ O(n^2)$ . "
What I have difficulties understanding is why did the author talked about an arbitrary function $ f(n)$ instead of directly $ n^2$ .
I mean why didn’t the author wrote
"When we say “the running time is $ O(n^2)$ ,” we mean that for any value of $ n$ , no matter what particular input of size $ n$ is chosen, the running time on that input is bounded from above by the value $ cn^2$ for some +ve $ c$ and sufficiently large n. Equivalently, we mean that the worst-case running time is $ O(n^2)$ ".
I have very limited understanding of this subject so please forgive me if my question is too basic.
