How do I allow MySQL connections through SELinux? - Server Fault

https://serverfault.com/questions/240015/how-do-i-allow-mysql-connections-through-selinux

Saved by uncleflo on July 11th, 2019.

I'd like to for once leave SELinux running on a server for the alleged increased security. I usually disable SELinux to get anything to work. How do I tell SELinux to allow MySQL connections? The most I've found in the documentation is this line from mysql.com: If you are running under Linux and Security-Enhanced Linux (SELinux) is enabled, make sure you have disabled SELinux protection for the mysqld process.

DIY 24v LiFePO4 Solar Battery Bank! Beginner Friendly, 2.4 kWh, Cheap, Full Tutorial! - YouTube

Saved by uncleflo on June 23rd, 2019.

Safety Update: If the cells have a voltage difference of more than .2 of a volt (example: one cell is 2.7 volts, and another cell is 3.5 volts), you should not parallel connect, and instead discharge the higher voltage cell with a 25-50 watt, 1.5-2.7 ohm resistor. Just attach the leads of the resistor to the individual higher voltage cell, and wait till it is at a voltage that is closer to the other cells. When they are within .2 volts of each other, then you can connect them in parallel and allow them to equalize. Another way to do this is to charge the lower voltage cells, but 3 volt chargers are not easy to find, so I would stick to the resistor method. These resistors only cost a dollars each, and you can find them at most electronics supply stores.

sql - MySql : Grant read only options? - Stack Overflow

https://stackoverflow.com/questions/20036547/mysql-grant-read-only-options

Saved by uncleflo on June 23rd, 2019.

Is there a way to group all read operations in grant ? If there is any single privilege that stands for ALL READ operations on database. "Reading" from tables and views is the SELECT privilege. If that's what you mean by "all read" then yes: However, it sounds like you mean an ability to "see" everything, to "look but not touch." So, here are the other kinds of reading that come to mind: "Reading" the definition of views is the SHOW VIEW privilege. "Reading" the list of currently-executing queries by other users is the PROCESS privilege.

Product requirements document - Wikipedia

https://en.wikipedia.org/wiki/Product_requirements_document

Saved by uncleflo on January 18th, 2019.

A product requirements document (PRD) is a document containing all the requirements to a certain product.
It is written to allow people to understand what a product should do. A PRD should, however, generally avoid anticipating or defining how the product will do it in order to later allow interface designers and engineers to use their expertise to provide the optimal solution to the requirements. PRDs are most frequently written for software products, but can be used for any type of product and also for services. Typically, a PRD is created from a user's point-of-view by a user/client or a company's marketing department (in the latter case it may also be called Marketing Requirements Document (MRD)). The requirements are then analysed by a (potential) maker/supplier from a more technical point of view, broken down and detailed in a Functional Specification (sometimes also called Technical Requirements Document).

Mounting NFS on a Windows Client

https://mapr.com/docs/51/DevelopmentGuide/c-mounting-nfs-on-a-windows-client.html

Saved by uncleflo on January 3rd, 2019.

Complete the following steps to mount NFS on a Windows client: The UID and GID values are set in the Windows Registry and are global on the Windows NFS client box. This solution might not work well if your Windows box has multiple users who each need access to NFS with their own permissions, but there is no obvious way to avoid this limitation. To set up the Windows NFS client, mount the cluster, map a network drive, and configure the user ID (UID) and group ID (GID). The Windows client must access NFS using a valid UID and GID from the Linux domain. Mismatched UID or GID will result in permissions problems when MapReduce jobs try to access files that were copied from Windows over an NFS share. Because of Windows directory caching, there may appear to be no .snapshot directory in each volume's root directory. As a workaround, force Windows to re-load the volume's root directory by updating its modification time (for example, by creating an empty file or directory in the volume's root directory).

NFS - which ports to open? - Storage - Discussions

https://discussions.citrix.com/topic/289912-nfs-which-ports-to-open/

Saved by uncleflo on December 23rd, 2018.

No problem connecting to NFS with firewalls disabled,but even with TCPView it's not obvious which ports require opening.
We've opened port 2049 for both UDP and TCP and all seems well, but there's a selection of ports mentioned across the web for NFS. So with XenServer just 2049? Sharing filesystems by NFS: Regardless of which choice is made for ID mapping you will need to adjust any firewall the system is using so that NFS clients can communicate with the server. You will need to ensure that the following ports are open before sharing any filesystem: UDP: 111, 1039, 1047, 1048 and 2049. TCP: 111, 1039, 1047, 1048 and 2049. See _this article_ Tobias

How can we find the tf-idf value of a word in the corpus?

https://www.researchgate.net/post/how_can_we_find_the_tf-idf_value_of_a_word_in_the_corpus

Saved by uncleflo on December 23rd, 2018.

I am working on text classification using SVM. In a paper (Fuzzy Support vector machine for multi-class text categorization) the author has reduced the features(words) by applying the following criteria: "Eliminate the words that are ICF>log2, Uni<0.2 and TF_IDF<26". My question is how can we find TF_IDF value of a word. TF is a local measure and IDF is a global measure. TF_IDF gives different value for a word in each document. TF-IDF is the acronym for Term Frequency–Inverse Document Frequency. This metric aims at estimating how important is a keyword not only in a particular document, but rather in a whole collection of documents (corpus). Actually, a lot of common words like articles or conjunctions may appear several times in a document but they are not relevant as key-concepts to be indexed or searched. TF (Term Frequency) provides a measure about how frequently a term occurs in a document.

Saved by uncleflo on December 23rd, 2018.

Mailchimp have suggested adding a CNAME record as following to the DNS records. I am not without experience in these matters and have replaced the 'yoursite.com' with the domain name and as far as I can tell have done everything ok .... but it replies with this. An unexpected error occurred. If this issue continues, contact support. Chat is currently offline so I thought I would ask the question here and see if anyone has had similar problems. Sorry to hear about the error when adding the cname record. I have a suggestion that may help resolve the issue when adding you cname record to your dns zone file. When adding the record you may need to remove the "yoursite.com" section from the record as the cname will already be created as a subdomain of your primary domain. This means when adding the record in the host section it should be added as k1._domainkey only and not k1._domainkey.yourdomainname.com. I also tried this on a test domain to ensure the record would save properly. Below I have also pasted a screenshot of how to properly submit the cname record. If for any reason you continue to recieve and error after adding the record please contact our 24/7 customer support line so that our representatives may further research the error.
