Containers: A Complete Guide | IBM

https://www.ibm.com/cloud/learn/containers

Saved by uncleflo on May 12th, 2019.

This guide looks at the importance of containers in cloud computing, highlighting the benefits and showing how containers figure into such technologies as Docker, Kubernetes, Istio, VMs, and Knative. A container is a small file that packages together application code along with all the libraries and other dependencies that it needs to run. By packaging together applications, libraries, environment variables, other software binaries and configuration files, a container guarantees that it has everything needed to run the application out of the box, regardless of the operating environment in which the container runs. A key characteristic of a container is that it is small and fast because it uses some of the underlying host operating system's resources to run rather than containing a whole OS of its own.

Waterfall model - Wikipedia

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

Saved by uncleflo on January 18th, 2019.

The waterfall model is a relatively linear sequential design approach for certain areas of engineering design. In software development, it tends to be among the less iterative and flexible approaches, as progress flows in largely one direction ("downwards" like a waterfall) through the phases of conception, initiation, analysis, design, construction, testing, deployment and maintenance. The waterfall development model originated in the manufacturing and construction industries; where the highly structured physical environments meant that design changes became prohibitively expensive much sooner in the development process. When first adopted for software development, there were no recognized alternatives for knowledge-based creative work.

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.

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:

SpaceSniffer - Visualizing Layout Disk Space

http://www.uderzo.it/main_products/space_sniffer/download.html

Saved by uncleflo on December 20th, 2018.

SpaceSniffer is a freeWare (donations are welcome) and portable tool application that lets you understand how folders and files are structured on your disks. By using a Treemap visualization layout, you have immediate perception of where big folders and files are placed on your devices. Treemap concept was invented by Prof. Ben Shneiderman, who kindly permitted the use of his concept into this tool. Start a scan process and see the overall situation. Bigger are the elements on the view, bigger are folders and files on your disk. You need more detail on a big folder? Just single click on it. The selected element will be detailed with its content. Need more and more detail? Keep selecting elements and they'll discover their secrets to you. Need a larger view of a small folder? Then double click on it, and it'll zoom to the full extent of the view. If you need to understand why no more free space is left on media, keep following bigger elements. Maybe you want to focus only on particular file types... ok. Just type the file type on the filter field (example: *.jpg) and press enter. The view will react and show you only JPEG files.

Data Warehousing Summary Tables

https://mariadb.com/kb/en/library/data-warehousing-summary-tables/

Saved by uncleflo on June 27th, 2018.

This document discusses the creation and maintenance of "Summary Tables". It is a companion to the document on Data Warehousing Techniques. The basic terminology ("Fact Table", "Normalization", etc) is covered in that document. Summary tables are a performance necessity for large tables. MariaDB and MySQL do not provide any automated way to create such, so I am providing techniques here. (Other vendors provide something similar with "materialized views".) When you have millions or billions of rows, it takes a long time to summarize the data to present counts, totals, averages, etc, in a size that is readily digestible by humans. By computing and saving subtotals as the data comes in, one can make "reports" run much faster. (I have seen 10x to 1000x speedups.) The subtotals go into a "summary table". This document guides you on efficiency in both creating and using such tables.

How to manually install the Securly SSL certificate in Chrome

https://support.securly.com/hc/en-us/articles/206081828-How-to-manually-install-the-Securly-SSL-certificate-in-Chrome

Saved by uncleflo on May 30th, 2018.

You would want to install the Securly SSL certificate in your Chrome browser to ensure the best browsing experience. The certificate does not control the level of filtering or what sites are allowed. The certificate will prevent errors on sites that Securly decrypts. Without the certificate, sites like Google.com and Facebook.com will show privacy errors, users will perceive this as the internet being “broken”. To install the Securly SSL certificate manually in Chrome, open ‘chrome://settings’ in your Chrome browser (version 59.0.3071 and above)

Full-Stack Cloud Native Monitoring Strategies

http://realscale.cloud66.com/full-stack-cloud-native-monitoring-strategies/

Saved by uncleflo on December 27th, 2017.

It is the weekend, late at night, or first thing Monday morning and you receive the dreaded phone call or SMS: “The application is down! We need all hands to figure this out!” After spending hours trying to track down the issue by reviewing logs, looking at the currently deployed code, and hundreds of IM exchanges, you finally find it – someone deployed a patch to production late Friday and it broke an important part of your application. You have probably been there. While tracking down issues can be difficult for any application, cloud native applications are particularly difficult. Applications are deployed to multiple servers across any number of zones. Servers have been created and destroyed. And the amount of traffic you must handle makes it hard to read log files (even centrally managed log files). So, how do you solve the need for monitoring in a cloud native architecture? While every application’s needs are different, we must first understand the options available to us. This article provides an overview of the goals of monitoring and the types of cloud native monitoring available, to help provide some insight into monitoring your Realscale applications.

Saved by uncleflo on October 31st, 2016.

ZFS, short form of Zettabyte Filesystem is an advanced and highly scalable filesystem. It was originally developed by Sun Microsystems and is now part of the OpenZFS project. With so many filesystems available on Linux, it is quite natural to ask what is special about ZFS. Unlike other filesystem, it is not just a filesystem but a logical volume manager as well. Some of the features of ZFS that make it popular are: Data Integrity - data consistency and integrity are ensured through copy-on-write and checksum techniques; Pooling of storage space - available storage drives can be put together into a single pool called zpool; Software RAID - Setting up a raidz array is as simple as issuing a single command; Inbuilt volume manager - ZFS acts as a volume manager as well; Snaphots, clones, compression - these are some of the advanced features that ZFS provides.

14.4. Introduction to SELinux

http://debian-handbook.info/browse/stable/sect.selinux.html

Saved by uncleflo on March 26th, 2015.

SELinux (Security Enhanced Linux) is a Mandatory Access Control system built on Linux's LSM (Linux Security Modules) interface. In practice, the kernel queries SELinux before each system call to know whether the process is authorized to do the given operation. SELinux uses a set of rules — collectively known as a policy — to authorize or forbid operations. Those rules are difficult to create. Fortunately, two standard policies (targeted and strict) are provided to avoid the bulk of the configuration work. With SELinux, the management of rights is completely different from traditional Unix systems. The rights of a process depend on its security context. The context is defined by the identity of the user who started the process, the role and the domain that the user carried at that time. The rights really depend on the domain, but the transitions between domains are controlled by the roles. Finally, the possible transitions between roles depend on the identity.
