How to Test Your Lens | B&H Explora

https://www.bhphotovideo.com/explora/photography/tips-and-solutions/how-to-test-your-lens

Saved by uncleflo on January 6th, 2019.

So, you just bought a shiny, new, and maybe expensive, lens for your camera, and being the savvy consumer, you did your homework. You pored over customer reviews on the B&H Photo website, read online reviews splattered all over the Internet, grabbed a copy of every photo magazine that reviewed the lens, bookmarked dozens of websites, and now have the lens’s MTF curve charts burned into your retinas. Now, your lens is here and it is time to go out shooting. Honestly, not a problem. Your lens should be as good as it can be and, as photographers, we want to take photos. So, stop reading and go out and make some photographs! Still here? OK, let me tell you why you might want to test that lens yourself. The main reason is that even with today's precision computer-controlled manufacturing techniques, there are variations in each and every lens that rolls off an assembly line. This means that some examples will be better than others. Some lenses will be outstanding and others will make you wonder if all of those glowing reviews you read online were completely bogus.

Best codec for game, video and screen recording - Bandicam

https://www.bandicam.com/support/tips/best-codec/

Saved by uncleflo on January 6th, 2019.

What is the best video codec for game recording, video recording, and screen recording? If you use a high-compression codec, you can get a small video file, but the encoding speed might be slower. If you use a high-quality codec, you can get the best quality video, but the video file size might be larger. If you use a high-speed codec, you can reduce CPU usage, but the video file size might be larger. So, you have to choose the best video codec by yourself to meet your recording needs.

Comparing x264 “RF” settings in Handbrake (examples) | mattgadient.com

https://mattgadient.com/2013/06/20/comparing-x264-rf-settings-in-handbrake-examples/

Saved by uncleflo on January 6th, 2019.

Here, I’m taking a look at various RF settings in Handbrake, both in terms of visuals and filesize. I started with encodes from the “24” DVD (Season 6, Episode 1). If you have the same DVD and are looking to reproduce this test, the following settings were used: I tested the following RF values (listed in Handbrake under “Constant Quality”: 0, 10, 18, 20, 22, 24, 26, 28, 30, 32 I’ll start with a few screenshots at different RF values. There’s a video below too, but it comes with a bit of a caveat so might not show everything well for you. Pictures should work for nearly everyone. Note that the first one (RF0) is for reference (lossless). Worth noting that x264’s psychovisual enhancements (trellis, etc) do a pretty good job of keeping detail where you’d notice it (the face), at the expense of the stuff you normally wouldn’t notice while watching (like those background areas). Of course, this only goes so far – once the RF value is high enough, there’s no saving Jack’s facial features from the effects of compression!

Saved by uncleflo on January 6th, 2019.

Youtube video quality and bitrate… What kind of compression does YouTube use? Every time we post a video on Youtube will ALWAYS recompressed. Youtube DO NOT leaves intact the video posted. YouTube, and a few of the other video services, also automatically deliver different video codecs to different platforms like iOS or Windows. Youtube recommends sending videos with high bitrates but after several tests I have verified that it does not change the quality beyond a certain bitrate, it is more important the quality of the source of acquisition rather than the bitrate. How much does Youtube compress video sent? How much the bitrate is allocated to video based on resolutions, youtube will assign a different bitrate to each resolution, and use 2 types of CODEC (H264 and VP9)

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.

Weighting words using Tf-Idf - NLP-FOR-HACKERS

https://nlpforhackers.io/tf-idf/

Saved by uncleflo on December 23rd, 2018.

If I ask you “Do you remember the article about electrons in NY Times?” there’s a better chance you will remember it than if I asked you “Do you remember the article about electrons in the Physics books?”. Here’s why: an article about electrons in NY Times is far less common than in a collection of physics books. It is less likely to stumble upon the “electron” concept in NY Times than in a physics book. Let’s consider now the scenario of a single article. Suppose you read an article and you’re asked to rank the concepts found in the article by importance. The chances are you’ll basically order the concepts by frequency. The reason is simply that important stuff would be mentioned repeatedly because the narrative gravitates around them. Combining the 2 insights, given a term, a document and a collection of documents we can loosely say that:importance ~ appearances(term, document) / count(documents containing term in collection).

Having problems adding Mailchimp's suggested CNAME - GoDaddy Community

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.

DMARC - Wikipedia

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

Saved by uncleflo on December 23rd, 2018.

DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email-validation system designed to detect and prevent email spoofing, the use of forged sender addresses often used in phishing and email spam. It is built on top of two existing mechanisms, Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM). It allows the administrative owner of a domain to publish a policy in their DNS records to specify which mechanism (DKIM, SPF or both) is employed when sending email from that domain; how to check the From: field presented to end users; how the receiver should deal with failures - and a reporting mechanism for actions performed under those policies. A DMARC policy allows a sender's domain to indicate that their emails are protected by SPF and/or DKIM, and tells a receiver what to do if neither of those authentication methods passes – such to reject the message or quarantine it. The policy can also specify how an email receiver can report back to the sender's domain about messages that pass and/or fail.[2]

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.
