I'm curious if there is an updated set of resources to learning/advancing in Clojure since the last time that I looked for such a thing. I've been using the mid-2010s resources on it mostly (i.e. Clojure for the Brave and True and the like). Anyone have a more refreshed list on the latest and greatest in Clojure resources?

Can this case handle any kind of upgrades?

I have a strong interest in computers, but I am woefully ignorant. Can someone please explain what NAS and RAID is? The best I can figure is that they are some sort of server operating system. Also, I know it's a bit unrelated, but may I also get some help as to how to rate processors? The only thing I know about them is that the more cores = better. I would highly appreciate any advice anyone may have. Thank you.

What can I do to learn about the basics of computer. I`m talking Motherboards, Memory Graphics, Card and all the stuff that go into them. I have been a gamer for most of my life but have never made any effort what so ever to understand stuff about the computer I`m playing on. I want to buy a new computer but don't have the foggiest what all the differences are. I'm currently looking up the different parts and trying to understand them. However the moment I think I have a rough idea of what I'm supposed to be looking at I watch a video online and they mention 100 different things that are meaningless to me. How did other people learn? Do you know of a video series that explains some of this. I've watched some of the Linus Tech Tips and thought some of them are very basic and I can understand, the majority of them expect to have at least some understanding. Any help would be greatly appreciated. (Apologies if I`m posting this in the wrong place)

Since sound is an open topic discussion, i share here one article from Yamaha Blog with Dr. Floyd Toole, who is a famed loudspeaker and acoustics expert and weighs in on the importance of listening through neutral speakers. Yes, neutral speakers. Check it out Yamaha Blog - How We Interpret Sound: An Interview with Dr. Floyd Toole

I'm looking for a good book for a beginner C++ student. Can't be too expensive, like 0-30$

*My guides or reference materials will be kept as "work in progress" forever as I intend to keep on improving and updating them as long as I am able. There are so many things to cover and I have to search again on some great stuff I have used to help others over the years. Let me start off by saying, whether you're interested in photography, cinematography, or even just recording sound: While having high quality expensive gear would be nice, don't let the lack of having such gear stop you from being creative. As you progress, gain experience, you will learn to understand what your gear is capable of doing and what its limitations are. With that you will learn to figure out where you need to upgrade or replace to improve without going out and buying an entirely new set of more expensive gear. Note: some of the links I post will have a number next to them in brackets. This indicates that there are more than one good explanations or methods to do certain things. Ok while my other guide on helping beginners choose between a DSLR/Mirrorless camera and a proper video camera, I thought I'd start another thread where I post links and videos on topics that people who are interesting in making videos or improving their photography skills should know. If you have links to guides, videos, etc. that you believe will provide knowledge to budding film makers, and to photographers too because there are some overlapping of knowledge, feel free to share them. As this guide is intended for beginners I will cover mainly the basic concepts. For more advanced or technical concepts, I will try to cover them as a Q&A. I also doubt if I will cover everything here, such as color correction, different settings for your speedlights, setting exposures, operating your camera, and so on. I am intending this guide to act as a primer to help beginners improve upon some of the very basic stuff they should know. Feel free to suggest topics you think I should cover, but I withhold the right to decide whether they get added or not. Guides Aspect Ratio/Cropping Choosing a good aspect ration for your video, different genres of film or different storylines of film may require the use of different aspect ratio. 16:9 is not always the best choice to use, as this video will explain. Aspect ratio: which should you choose Perspective Understanding perspective when choosing a lens or selecting a focal length to use. The Dolly zoom, sometimes referred to as the Hitchcock zoom/effect, is a pretty good way of explaining to you what happens to your photo or video's perspective when you select a focal length to use or change focal lengths during filming. As a film technique, it is great when used appropriately, but it should not be used all the time. For photographers, observing the effects of the technique will show you the differences between using a wide angle lens and a telephoto lens. Dolly Zoom Wide angle vs Telephoto Tips for posing your subject(s) I saw these videos yesterday, created by a wedding photographer named Lexia Frank, and her videos give you quick and easy to understand explanations of how to tell your subject to pose for you in front of the camera. Now while they apply mostly to photography, some of what her tips can be used in video.

It's more realistic looking than what fashion magazines use. Light modifiers guide (1) Camera lens filters, choosing a lens filter and understanding polarizing filters Gear and accessories Video Gear Guide for DLSR/Mirrorless shooters I'll also make a list of gear and accessories later, as a starter for beginners. The following are the basic gear you will need, and I will expand on each and provide tips on choosing the right one. Camera, for this you can read my guide about DSLR/Mirrorless cameras and video cameras. This will help you make a decision on which type of camera to get if you want to shoot video. For photos, 80% of the cameras these days are good. Or just let us know your requirements and we will help you find the right camera for you. Lens (for interchangeable lens cameras, both photo and video). As long as you have a lens or set of lenses that cover the 24mm to 200mm focal length range (35mm equivalent), you are set for 95% of your needs. The additional items mentioned below are for videographers. Audio recording Built in microphones do not record clean audio. Especially those built into DSLR/Mirrorless camera bodies that have moving parts (reflex mirror, shutter). Some are even sensitive enough to pick up the noise of the AF and IS system in the lenses. Hence using an external microphone attached to the camera or an external recorder is recommended. Your basic camera setup should have at least 1 external microphone (e.g. Rode Video Mic) or a recorder (e.g. Zoom H1). The advantage of an external microphone is that it is either off camera or mounted on camera with a mount that is designed to reduce vibrations. The disadvantage, audio amps in DSLRs, mirrorless cameras and consumer camcorders tend to be limited. External recorders can be mounted to a camera using a variety of mounts (hotshoe adapters, mini arms, etc). Higher end recorders come with multi channel recording capability and support for a variety of inputs. External records such as the Tascam DR-100 or DR-60D, or the Zoom H4n have high quality audio amps built in and are able to provide phantom power to external microphones that require them. While a person on a budget may consider a low cost video mic or recorder I would recommend that if budget is not a major factor in your purchasing you should get the Tascam DR-100. Why? Dual battery support (it comes with a Li-Ion battery pack and you can also use 2x AA batteries) The two directional mics in front are very sensitive, it also comes with support for 2x XLR connections. It has a line out port and a headphone port for monitoring audio. This way you can use a line out cable to feed audio to your camera, while recording on the DR-100's memory card at the same time. You use the audio track in camera for syncing with the better audio recorded by the DR-100. The same can be done with the Zoom H4n, however the two mics on the H4n are not aimed straight forward. They can be rotated to provide a 90 degree or 120 degree coverage. Additional microphones that videographers should invest in: Shotgun mic (e.g. Rode NTG2), and perhaps a boom stick for the times when the audio source is a distance away from the camera. Wireless lavalier microphones (e.g. Sennheisers), useful when doing interviews. I personally recommend that you have at least two lavalier sets. Wireless lavs are better when you are working alone and don't have an assistant to hold a boom mic. Other accessories you need will be wind covers and dead cat wind muffs, they are very useful for outdoor recording and can reduce ambient and background noise. Tripod and tripod heads If you want to keep your camera stable, safe, and the camera is going to stay in one place then invest in a good sturdy tripod. Do not buy those cheap flimsy aluminum ones sold in a general department store. You don't have to invest in an expensive Manfrotto or Gitzo, you can go for ebay brands such as Benro which are pretty good. However, before you buy the tripod make sure it is solid enough to support the way of your camera and accessories. (Tip: always add a few extra kilos to your gear's weight to be on the safe side.) Also do not forget to make sure that it can support the tripod head you choose. You do not want a small tripod for a large tripod head. Now for tripod heads, the type of head you choose will depend whether you are a photographer or videographer. There are a variety of tripod head systems for photographers. I generally prefer a ballhead with friction control and Arca-Swiss style quick release system but perhaps if you enjoy macro photography you want to get a geared head, or for those who do panoramas get a pano head. For videographers, you want a fluid video tripod head with a good handle. You want something solid, able to hold the weight of your gear and has a counter balance system that will help keep things stable. The Manfrotto 502HD is a good video tripod head. I also recommend that people avoid getting tripods with a geared central column system. A good tripod and tripod head will last you years. You can also invest in a monopod, however keep in mind you need to keep a hold of them. Unlike tripods they are not meant for hands free use, nor do they provide the very solid stability of a tripod. Monopods are ideal for people who move around with their camera a lot, such as hikers who like to photograph. And they rarely are ideal for videographers, though a long monopod can be used to film from a high angle. Camera rig (for video) Whether you are using a tripod, or want to shoulder mount your camera, or hold the camera in other ways you will need a good rig for the camera and accessories. Especially for videographers with a DSLR/Mirrorless camera and need to attach microphones, audio recorders, field monitors and other accessories. A basic rig for the camera should have a mounting plate and support for two 15mm rods. A better rig will allow you to quickly switch from tripod to shoulder mount and vice versa. You will need several attachment points, either mounted to the rods or as part of the rig's skeleton for mounting accessories (mainly for DSLR/Mirrorless camera users). Focusing systems When recording video, unless you are doing home/family/vacation videos and do not have time to carry around all the extra gear, I always recommend that you disable the auto focus and learn to use manual focusing properly. AF systems do not know what you want to focus and how you want the focus to change throughout your filming. Also, I recommend that you invest in a follow focus system as turning the focus ring on the lens with your hands can introduce instability in your recording. A good follow focus will be adjustable to fit a variety of lens sizes, will operate smoothly and will mount onto the 15mm rods. With focusing comes the issue of know if you are focusing properly. Optical and electronic viewfinders in cameras, while they generally have an indicator of some sort that tells you of something is in focus or not, rely on the focus points of the AF system in your camera. They are also too small to see if you are focusing properly when pulling focus throughout the scene. The back or side LCD on your camera is a better option, however even the largest screen on a DSLR/Mirrorless camera is only a few inches in size. And rarely do DSLR/Mirrorless cameras for video include helpful features for videographers. Using a viewfinder loupe that mounts on the LCD can be a bit more helpful. However, unless you are using a proper video camera (most video cameras have LCD displays that show focus peaking), I recommend that you invest in a good field monitor that can be mounted to your rig and can utilize the clean output of your camera. A good field monitor should have the following features Focus peaking to assist your focus pulling False color display to show your exposure levels Guidelines to help you frame your scenes for different aspect ratios Filters While modern digital cameras allow you to control the shutter speed, video recording frame rate, ISO and aperture settings, having and using filters in front of your lenses is still essential. For two reasons Your camera settings may have a limited range. Changing shutter speed, ISO and aperture can change the recorded image in ways you don't want. Two basic types of filters that photographers and videographers should invest in Neutral Density filters (ND), they can help reduce the amount of light reaching the sensor. Soft, Hard and Reverse edge Gradient Neutral Density filters, especially useful when part of the scene contains extreme shadows or highlights. ND gradient filters can help ameliorate bad lighting conditions or limited dynamic range capability of your sensor. Other filters you can use are color filters, circular polarizers and infrared filters. Take care when using such filters. I generally do not recommend them for videographers. Polarizers and IR filters can be very useful for photographers who know how to use them. Dolly, sliders, accessories that help you add motion to your shots Lights Other accessories The main thing is DO NOT SKIMP out investing in good gear and accessories. Workflow I will only post links to various workflow guides for software that I have experience with. The reason being, while anyone who is familiar with the software can make a workflow guide, if I am not familiar with the software I wouldn't trust myself to judge if the guide is good or someone is just trying to push how they do things which may not always be the optimal method. Mastering Adobe Lightroom: Basic Post Processing workflow Another Lightroom and Photoshop workflow Adobe Premiere Pro workflow for DSLR Working as a professional Here I will cover some aspects of what will be involved when you want to work as a professional. Either for yourself, a freelancer that offers services for agencies, or a contracted professional. Recording video for your use, either for personal stuff like family/holiday videos or even for your own Youtube tech channel like Linus, it's easy to do. You define your own requirements. However when you record footage for someone else to use, that's where you have to talk to the other party and ask them how they want things. You can't always choose what you want to do, they may tell you they need the video format in ProRes but your camera only records H.264 and they may or may not accept a converted video, what will you do? I can already give you an example of what you may be required to do when you are working either as a freelancer or contracted professional for an agency that has their own requirements. This is the document given to all freelancers and producers who record footage for an agency where I sometimes work freelance. (ILO_technical_note_for_producers_ENGLISH2015.doc) BBC's guidelines are another example. TIP: If you get hired to work for a client that requires you to record video in 4K but they only have the capacity to handle Standard Definition (SD) video, tell them they are being foolish. Politely of course.

Hello everyone! I just wanted to share a problem i recently had with an HP laptop. The problem was in a very unexpected place so if you ever run into it you know where to look. So this client had a laptop with a non-working screen lighting. After poking around with my handy multimeter i discovered that there was no power going to the inverter but there was power on the motherboard's connection to it. So what turned out the problem was, that the pins on the connector had melted, losing contact. They were so small that i needed a magnifying glass to see it, which is exactly why this was such a hard to find issue. Ended up just soldering a wire that replaces the molten link. Hope this information serves good to someone. Will be interested to see what hard-to-find problems you have ran into in your practice.

Hi guys and girls! I was wanting to know if there are some good resources to build myself a knowledge of networking. Some time down the road I'll be in charge of networking my new home and I need to know all the nuts and bolts behind home networking. Is there a good book I should read, how do I know what components to buy, how do I set them up and configure them etc. ? I'm a complete networking noob as of now all I know is they're a series of tubes, I'm not that bad, but I'm pretty bad. I've had lots of experience with just general PC hardware and I'm quite knowledgeable in that regard but I've never pondered in networking. Reckon you could give me some helpful resources to get me hooked? Cheers!

Basicly I want to create a thread where anyone could go at anytime and get some helpfull advice from you veterans out there. As this forum is getting bigger every day, I want to create a combined thread of all of your advice that you will be posting in this thread (assuming this hasn't been done proberly before). So if you are on with this idea, please. Feed us newbies with your knowledge and we'll get this thing started! .:EDIT:. If we get a decent ammount of advice, tips and tricks I will gather every piece of it, and make a guide thread in the guides section.

I am curious about how everyone here came about to know their various aspects of IT! I would love to read some of your back stories and how you as individuals gained your knowledge of all things electric Would love to know various courses you attended, people that influenced you and even some videos you may have watched to broaden your interests Thanks guys
