How to tell to the user that a web app is optimized for a specific browser?

My web app is voluntary optimized for Chrome. It works on IE and Firefox but the user can find some design issues with old browsers like IE 8. It’s a professional app’ on an intranet and a some users don’t use Chrome.

I’d like to display on the Home page something like “This site is optimized for Chrome” and may be a link to https://www.google.com/chrome/

Is-it a good idea to do that ? What is the “best” way to inform the user this app’ is optimized for a specific browser ? Should I encourage the user to download Chrome ?

Looking for a specific quote about keys and transparent encryption implementation

I’m struggling to find a quote advising that we should be comfortable in sharing details of encryption methods and implementation with would-be attackers and the system still remain secure. The idea is that the keys are what we should be protecting as opposed to some obscurity in our code and approach.

Does anybody have the quote I’m talking about?

Maximum flow with maximum flow on specific edge

I am trying to solve the following problem:

We’re given a network flow $ (V,E,c,s,t)$ and an edge $ (u,v)$ . We have to provide an algorithm that computes the maximum flow which has maximum flow on $ (u,v)$ also.

The idea that I had was, computing max flow and on the residual graph trying to compute a cycle that starts from $ s$ and passes through the edge $ (u,v)$ and trying to increase $ (u,v)$ ‘s flow while decreasing the flow from other edges. In other words, trying to maximize the flow of $ (u,v)$ while preserving the maximum flow value. But I feel like there’s a simpler way.

Can someone point me in the right direction? Is my thinking correct? If not how should I approach the problem?

Any help is appreciated! Thanks!

Automatically move files from one folder to a specific folder on SharePoint

I am investigating for a possibility for SharePoint Online to automatically and dynamically move files into specific folder.

We have a folder on a SharePoint library where files were exported into from another source. These files are labelled with account number and date of the report. On the other side of things, each of these accounts have a folder on SharePoint with the account number as a folder name within the same SharePoint site. Is it possible for SharePoint (SharePoint Online) to automatically move these files into corresponding folders?

I am thinking about SharePoint Workflows, but SharePoint Designer doesn’t seem to have an “out of the box” solution, or perhaps I am missing something.

Can someone help? Many thanks.

How do I install a specific patch number version of Python?

This question here tells me how to install a specific version i.e. x.y.

I would like to install a specific version of Python x.y.z – eg 3.6.3 – while the default in Ubuntu 18.04 is Python 3.6.8.

Is there a way to install the specific patch number of the version of Python?

I tried the selected answer in the related question and I cannot install properly.

I am able to install a particular version, just not a patch number

DOD PKI CA access outside of of those specific certs?

I work for the government and mostly everyone installs the DOD PKI Certs on their private computers to be able to check email, admin stuff, etc.

I’m getting into networking, security, white hat hacking more and more and from my research, if I’m not mistaken, it sounds like if you install someone’s certs they have access to all data that passes through HTTPS.

I was always under the assumption that they could only access that data if you were accessing an application that they controlled (e.g. government email).

If the case is that they can still MITM attack everything once you’ve installed the certs then this makes me fairly uneasy. Can someone explain how this is possible? Thanks!
