users - How do daemons work? - Unix & Linux Stack Exchange

https://unix.stackexchange.com/questions/108502/how-do-daemons-work

Saved by uncleflo on January 4th, 2019.

If a user wants to execute a command, he has to first log in into a system. But some users in the system have /bin/false or /sbin/nologin set as a default shell in the /etc/password file. If I change /bin/bash to /bin/false in case of my user, I won't be able to log in into the system, so I also won't be able to run commands. But the shellless users do it anyway: How can a user without a shell execute a command? In POSIX, every running process has three User IDs (UIDs) associated with it; the real UID, which identifies the user who launched the process, the effective UID, which is used to determine what resources the process can access, and the saved Set-User-ID (SUID), which is the effective UID the process had when it started (at the point of the last exec() call). Of these, the effective UID is the most significant, since it is the one used when determining access control decisions regarding the process.

GraspingTech | How to Mount an NFS Share Using a Windows 10 Machine

https://graspingtech.com/mount-nfs-share-windows-10/

Saved by uncleflo on January 3rd, 2019.

Mounting an NFS (Network File System) share using a Unix-like operating system is pretty straight forward. But how do you mount an NFS share of a UNIX system from a Windows 10 machine? Keep reading to find out how. With that said let’s install the Services for NFS feature and mount an NFS share. The first thing we need to do is install the NFS Client which can be done by following the steps below: With the default options you will only have read permissions when mounting a UNIX share using the anonymous user. We can give the anonymous user write permissions by changing the UID and GID that it uses to mount the share.

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

Setting a FQDN for the NAS - Synology Forum

https://forum.synology.com/enu/viewtopic.php?t=131359

Saved by uncleflo on December 23rd, 2018.

When setting up the NAS, you need to enter in a server name. This becomes the hostname. How can I set a FQDN (i.e. NAS-Store.example.com) without it being wiped out all the time? You can just setup a ddns name and use it to get access (I'm guessing you wanna use that name to gain outside access to your NAS). There is a DDNS tab in Control Panel > External Access. Register your name there. I don't need to worry about DDNS. That is not an issue. As I run an internal DNS on my network, I can type in the FQDN of the NAS and get to it OK. That's all fine. I would just like to be able to give the NAS an FQDN and an SSL certificate to match it, so I do not get any warnings that the cert is incorrect for the NAS when I have external clients use the Cloud Station. I don´t you buy a domain name, setup it up by using DynDns client and give the domain name to your clients to connect to, and then set your internal DNS with that same domain name to point to the internal IP, and also set the name of the NAS with that domain name.

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.

word2vec - Google Code Archive

https://code.google.com/archive/p/word2vec/

Saved by uncleflo on December 23rd, 2018.

This tool provides an efficient implementation of the continuous bag-of-words and skip-gram architectures for computing vector representations of words. These representations can be subsequently used in many natural language processing applications and for further research. The word2vec tool takes a text corpus as input and produces the word vectors as output. It first constructs a vocabulary from the training text data and then learns vector representation of words. The resulting word vector file can be used as features in many natural language processing and machine learning applications. A simple way to investigate the learned representations is to find the closest words for a user-specified word. The distance tool serves that purpose. For example, if you enter 'france', distance will display the most similar words and their distances to 'france', which should look like:

Having problems adding Mailchimp's suggested CNAME - GoDaddy Community

https://uk.godaddy.com/community/Managing-Domains/Having-problems-adding-Mailchimp-s-suggested-CNAME-record/m-p/13683#M2625

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.

I'm setting up a new server, and want to support UTF-8 fully in my web application. I have tried in the past on existing servers and always seem to end up having to fall back to ISO-8859-1. Where exactly do I need to set the encoding/charsets? I'm aware that I need to configure Apache, MySQL and PHP to do this - is there some standard checklist I can follow, or perhaps troubleshoot where the mismatches occur? This is for a new Linux server, running MySQL 5, PHP 5 and Apache 2.

You Might Not Need jQuery

http://youmightnotneedjquery.com/

Saved by uncleflo on May 9th, 2018.

jQuery and its cousins are great, and by all means use them if it makes it easier to develop your application. If you're developing a library on the other hand, please take a moment to consider if you actually need jQuery as a dependency. Maybe you can include a few lines of utility code, and forgo the requirement. If you're only targeting more modern browsers, you might not need anything more than what the browser ships with. At the very least, make sure you know what jQuery is doing for you, and what it's not. Some developers believe that jQuery is protecting us from a great demon of browser incompatibility when, in truth, post-IE8, browsers are pretty easy to deal with on their own.

Instead of installing huge phpMyAdmin (~11Mb) and trying to figure out how to use all it's features, just upload one ~30Kb file and it's ready to use! Then access it via the browser (ex. http://yoursite.com/phpminiadmin.php). Script will ask you for DB login/pwd. After successfull db login you will see area where you able to enter any SQL commands (select, update, insert, etc.). Even if you don't know SQL it's still easy to: browse tables and see all the data, click to un/highlight rows
manage tables in DB, export and import data to .sql and CSV using 'quick links' on the top bar (see screenshots), see what databases you have permission with, check server status and statistics, ability to do CRUD (i.e. insert, select, update, delete), and launch any SQL supported by any version of MySQL. And due to it's simplicity script really fast and need just a little server resources! (your hosting provider will be glad ;)
