Canada Canada is a North American country comprising ten provinces and three territories. Positioned in the northern part of the continent, it extends from the Atlantic to the Pacific and northward into the Arctic Ocean. Canada is the world’s second-largest country by total area, and its common border with the United States of America is the world’s longest land border. ​ Canada has been inhabited for millennia by various Indigenous peoples. During the late 15th century, British and French colonial expeditions explored, and settled the region’s Atlantic coast. France relinquished virtually all its colonies in North America to the United Kingdom in 1763 following the French and Indian War, which was basically the North American Seven Years’ War. ​ While walking the Sundance trail near Banff I met my first wolves face-to-face. There was a pack of about seven and having bred and trained a few German shepherd dogs I noticed their tails were relaxed and their attention was not on me. So, I kept very still and avoided direct eye contact. That day they passed me by on a ridge about ten metres away. A couple of days later, while on the same trail, they were on the track about 50 metres in front of me. Now the prudent thing to do would be to turn back, but I am not like that. So, I waited and watched as they moved closer. Again, the wolves seemed relaxed and showed no signs of aggression, anyway, it was too late to retreat, and running was not an option, doing this might turn on their hunting instincts. Slowly they came closer until they were about six feet in front of me I am not sure why, but I started to talk quietly to them and slowly they came up to me and carried on walking past, a couple brushing against my legs. I knew it was the same pack, one of the females had a slight limp. During my stay in Banff, I met the wolves once more, and again they walked close enough that I brushed my hand over the back of one. Hell of a feeling I can tell you. Anyway, that brought on my love of these animals. Several years later I when staying in Canmore a town in Alberta’s Rocky Mountains I heard a local farm had looked after two young wolves and let them roam the farmland. They also had a rare white bison, so I contacted them to arrange a visit. Fantastic place and the owners looked after me and showed me around. Unfortunately, the two wolves were not around and two weeks later I had a disturbing email stating that the wolves had been shot and killed by another farmer. In 1867, Canada was formed as a federal dominion of four provinces due to the union of three British North American colonies through a coalition. This initiated an accretion of provinces and territories and the process of increasing autonomy culminated in the Canada Act of 1982. Canada is a federal state governed as a parliamentary democracy with a constitutional monarchy - with Queen Elizabeth II as its head of state (the Canadian anthem is the Royal anthem ‘God Save the Queen.’ The country is officially multicultural and bilingual, with a population of around 38 million as of 2020. Canada’s forward-thinking economy is one of the largest in the world, relying mainly upon its copious natural resources and well-developed trade systems. Canada ranks amongst the highest in international measurements of education, quality of life, government transparency, civil liberties, and economic freedom.

Choosing a Tripod 1. Weight A tripod’s weight should be considered from two perspectives. Will it be carried around? Used indoors? Or both? ​ I have: 2 x heavy tripods for indoor use. 4 x small tripods for tabletop, placing on low walls or a bonnet of a car. 1 x medium weight tripod for outdoor use - Remember that someone is going to need to carry it around. Mine attaches to my Bergan/rucksack which makes it easier to carry long distances. ​ 2. Stability Weight does not always equal stability. If possible, test the tripod with the camera on it along with the largest lens, light, flash, and microphone. Test it fully extended to see how stable it is. Will it be sturdy on a windy day? Will it take the knock of someone bumping it on the way past? Has it got hooks for weights? ​ 3. Leg Locks There is a lot of variation between manufacturers when it comes to the mechanisms used for locking legs into place. Often, it comes to personal preference, but secure locks are essential. My main tripods are Manfrotto, they offer quick-release locks that are stable, and I have found reliable. ​ 4. Leg Sections The number of sections used to alter the height on tripods can be a factor. If they have two sections, they will be longer when they are collapsed. Two is good because there is less playing around with extending and locking the legs, while three sections provide a more compact tripod when folded. ​ 5. Height How long is a piece of string? Depending on the type of photography, the height requirements of a tripod will vary. What is the maximum height needed? But also, how it operates at its minimum, and how big it is when it is all folded. In all honesty, having a tripod one can look into the camera’s eyepiece without having to bend is a bonus, there is nothing worse than a full day of leaning over to check the framing shots. ​ 6. Tripod Heads Tripod heads can either be bought with a tripod as a complete set or separately. One key aspect to consider about a tripod is how the camera attaches to it. There are numerous options available, and it is worth planning and considering the options, as the tripod head not only keeps your camera on the tripod but will determine how much flexibility you have once it is attached. ​ My preference is the quick release Manfrotto tripod heads, they are well built and extremely sturdy. Each of my cameras and GoPros have a Manfrotto tripod head fitted, so I can easily swap cameras or tripods. ​ The two main types of tripod heads are: ​ Ball and socket – are great for flexibility and moving your camera around, but I find them fiddley. ​ Pan and tilt – are great for locking into position and are usually more affordable. They are not as fluid to move around and take getting used to, but I prefer them.

Airbrush Troubleshooting Airbrushing comes with some inherent issues, these problems and troubleshooting them vary and can be experienced at any time no matter how experienced the user, here are a few. Bubbling in the gravity cup or suction bottle. ​ Can be caused by air pressure entering the paint reservoir. There are several reasons, most common are. ​ An air leak in the air cap or nozzle area. Solution – Tighten the loose Air Cap or Head. ​ Needle tip dry is dry and has blocked the nozzle. Solution - Clean or Replace the Tip Dry or Blocked Nozzle. ​ The air cap or head is loose. Solution – Replace worn or damaged nozzle seal. ​ The airbrush nozzle has a split. Solution – Replace the Split Nozzle. The spray pattern is off-centre . ​ Normally caused by a bent needle tip. The paint or fluid exits the airbrush and follows the bend on the tip of the needle. ​ Straighten the Needle Tip – This can be achieved with a flat sharpening stone or two pieces of 1” x 2” wood. I use a SharpenAir , which is a hand-held device designed specifically for repairing bent and damaged airbrush fluid needles. ​ Replace the Needle. Airbrush does not spray paint. ​ There are a few that can cause this, the most common are. A blocked nozzle often caused by poor cleaning. The solution for a Blocked Nozzle is to soak and clean the nozzle. ​ For a loose needle chucking nut when the needle is not moving with the trigger action. Solution - Check and tighten the needle chucking or locking the nut. ​ The paint consistency is too thick. Solution - Thin paint with appropriate thinner, reducer, water to a milky consistency. ​ Inappropriate low air pressure. Sometimes the paint can be slightly too thick, and the pressure is too low to atomize. Increase the air pressure accordingly. Airbrush sprays paint when the trigger is depressed for air. Caused because the needle is not sitting flush inside the nozzle or you have the wrong nozzle attached for the size of the needle. Otherwise, if the airbrush only sprays a blob of paint when the trigger is depressed then follow the Air On – Air Off method - first depress the trigger, then pull the trigger back for paint flow and then after spraying return the trigger forward before releasing the trigger/airflow. Shutting the paint flow off before the airflow will spray any residue paint off the tip of the needle. ​ Unscrew the needle locking nut. ​ Gradually push the needle forward until it rests inside the nozzle. ​ Tighten the needle-locking nut. Air pressure remains on when the trigger is released. Often due to many several reasons, like residue paint or solvents entering the air valve and affecting the air valve seal to swell or become sticky. A slack air valve closure or guide screw will not compress the air valve spring enough to fully return and shut off airflow. Disassemble internal air valve components and lubricate with airbrush lube and re-assemble. ​ Replace air valve seals if they appear eroded by solvents. ​ Tightening the air valve closure or guide screw will compress the air valve spring and shut off airflow. Poor spray or splattering of paint. There are several reasons, ranging from. Paint consistency. Solution - Reduce to a milky consistency. ​ Low air pressure. Increase air pressure until paint atomizes. ​ Damaged needle. Replace needle or repair using the SharpenAir device. ​ Tip dry or a partially blocked nozzle. Remove the needle and clean with a Q-Tip or cloth dampened using an airbrush cleaner (always wipe away, airbrush needles are very sharp). ​ Residue paint build-up in the needle cap, nozzle, or air cap. Clean and replace if indicated. Spray Spidering. Often caused if the paint has been over-thinned. Solution 1 - Add paint to the mix or reduce air pressure. ​ Solution 2 - Do not draw the trigger back so far or increase the distance from the surface. ​ Also, caused by spraying the paint too heavily on a non-porous surface. Solution - having the air pressure too high. Solution - Add paint to the mix or reduce air pressure.

HDD Error Management Hard Drive Error Management ​ A healthy primary becoming a RAW partition can be caused by several reasons, such as: ​ Virus infection Format failure Accidental OS shutdown Power outages ​ How to do RAW partition fix easily in Windows 7/8/10? There are a few ways you could choose from. ​ DISCLAIMER: The examples that I have illustrated are ones I employ to deal with hard drive problems. They might be dangerous to use for some systems. These procedures may also be ineffective. If you try them, you may cause damage or irreparable data loss. Because of this take great care. Therefore, I take no responsibility for anything you do based on my examples or the information that I have provided. ​ How to Fix: Internal or External HDDs that became RAW. A commonplace and bewildering problem with computers is the unexpected and mysterious disappearance of a hard drive (HHD) that has been working properly. It can be a horrendous experience to suddenly find that your data might be gone forevermore. I still get the stomach tightening when a message box reports that your HDD has given up the ghost. ​ It is easy to say, ‘ Don’t panic ’, but most inexperienced people will have that gut-wrenching moment when the hard drive is no longer usable. ​ If approached sensibly and carefully, the situation can usually be resolved, and the data saved. Below we will look at a few of the causes, fixes, and preventative measures for occurrences involving HDDs used with Windows XP and Windows Vista/7/8, Yes, I know they are old systems, but I know of a major computer store that still uses XP because of the cost and management implications of upgrading to MS Windows 10. ​ Error Messages Usual error messages associated with the inability to access an HDD. When attempting to access the drive in Windows you may see a message asking you to format the drive - ‘You need to format the disk in drive before you can use it, Do you want to format it?’ ​ DO NOT FORMAT THE DRIVE Another error that you may see when trying to access the drive in Windows from a program or the command line is - ‘ This volume does not contain a recognised file system. Please make sure that all required file system drivers are loaded, and that the volume is not corrupted. ’ ​ ​ ​ ​ ​ ​ ​ Attempting to run chkdsk with a RAW HDD to repair the problem will give the error – ‘chkdsk cannot be run on the drive’ The type of the file system is RAW. CHKDSK is not available for RAW drives.’ Before going on, you need to be aware of the risks involved. ​ If the problem with the drive is not a logical error but is a symptom of physical damage, the more you try to use or repair it, the worse the damage may become. ​ The drive should not be making strange clicking or beeping noises. If this occurs it indicates physical damage. ​ In these situations, I disconnect the drive from my windows machine and plug it into a purely Linux machine to repair or recover the data. Even so, this can make the situation worse. ​ If you wish to continue your own there are a couple of important rules to remember. If you do not have a dual boot system with Linux perhaps a friend does. ​ Do Not try to write anything to the raw DRIVE apart from trying to repair the Master Boot Record (MBR) and Boot Sector. Any other data transfer, deleting partitions, or attempting to format the drive can overwrite data on the drive. ​ If you have important data or photographs on the drive do not mess about it, take/send it to a professional for data retrieval. ​ Computer problems are erratic and not set in stone. So, try other ideas, search the web. Not every option will work so it is important to think laterally. ​ If the drive does not hold important data you can try to format it using the command line - I have had several successes, but also many failures. ​ If you do not need any of the data - use the 'Disk Clean' method below Open the Disk Management window and click on Disk Management in the left pane and make note of the disk in the middle pane of the disk that you want to clean or clean all (Fig: Be sure that you have the correct disk, check the number, mine is drive ‘T’ No. 4. You would not want to wipe clean the wrong disk. Press the Windows + C keys to open the search dialog, type command on the left side of your screen right-click the ‘ Command Prompt ’ tab and choose ‘ Run as Administrator ’ at the bottom of the page, and click the link. Once the Shell opens (Fig: 1) a line will display: C:\WINDOWS\system32\ Fig: 1 Type ‘ diskpart ’ (Fig: 2) and press ‘ Enter ’ Fig: 2 Beside DISKPART> type ‘ list disk ’ and press ‘ Enter ’ ​ You will see in (Fig: 3) that there are 6 disks listed 0 to 5, remember I am using disk 4. (Double, no triple check you have the correct disk before continuing) Fig: 3 Now the prompt (Fig: 4) displays ‘ Disk 4 is now the selected disk ’ ​ Beside DISKPART > type ‘ list disk ’ and press ‘ Enter ’ You will see in (Fig: 4) that I have 6 disks listed 0 to 5, remember I am using disk 4. (Double, no triple check you have the correct disk before continuing) ​ Beside DISKPART > type ‘clean’ and then press ‘ Enter ’ Fig: 4 Disk 4 will now be cleaned, once complete it will state ‘ DiskPart succeeded in cleaning the disk ’ (Fig: 5). Fig: 5 For a full clean, just type ‘ clean all ’ instead of ‘ clean ’ and press ‘ Enter ’ as before – a clean all will take many hours if you are using it on a large drive. ​ Go back to the Disk Management screen and format the drive, normally it will format fine using efat system, but I have had problems with some hard drives reverting back to RAW when trying to format them in NTSF .

Linux Linux is an open-source operating system (OS), it sits underneath the other software on a computer, receiving requests from programs and relaying those requests to the computer’s hardware. A Linux distribution (often abbreviated as distro) is an operating system (OS) made from a collection of software based on the Linux kernel and often a package management system. A few acts and feels like MS Windows or macOS, and are relatively easy to use, while others are more complex to use. I mostly use Linux Mint, Puppy, and Mageia, but only as a personal preference. If I had to choose one it is Linux Mint as I find it is a good all-round operating system. ​ I have two dual boot systems (where I can choose to boot into either Linux or Windows – or Linux or macOS) and one triple boot computer (where I can choose to boot into either one of two Linux distro or Windows). So, why so many computers and operating systems? I use the computers and operating systems for different things but do most of my programming on Linux. Other tasks can be done on any of the operating systems. The advantage of Linux is, when I log onto Linux Mint, I can also view and move across the data from MS Windows, modify it and then move it back without the need to boot into Windows. This is extremely useful if the Windows operating system crashes and I need an aspect of data fast, as I can use Linux to get what I need. Especially useful for data rescue . ​ Also, Linux is not as hungry on a computer's resources, so Linux operating system and its programs can be installed and run on older lower spec computers and hardware. ​ Linux comes in many distro types or versions, a few are: ​ Mint Puppy Linux Mandriva Mageia Kubuntu Arch Linux Ubuntu Fedora Ubuntu Red Hat OpenSUSE Mandrake CentOS MX Linux Gentoo Slackware Debian Free BSD Additional Links: ​ Install WINE How does Linux differ from other operating systems (OS)? But many Windows programs will run quite happily on a Linux operating system, but you will need Wine (not the fluid type). ​ Wine is a free Linux tool to run Windows compatible software on a Linux operating system, without the need of MS Windows. ​ Wine is an open-source Windows compatibility layer that can run Windows programs directly on a Linux desktop. Basically, this open-source project is endeavoring to re-implement enough of Windows from scratch that it can run all those Windows applications without needing Windows. Linux is like MS Windows and macOS (formerly OS X or iOS). Like other operating systems, Linux has a graphical interface, and the same kinds of software you are accustomed to. There is a vast repository of free software available, an exceedingly small list is: ​ Word processors and PDF Editors – LibreOffice , PDF Studio , or OpenOffice Code and Text Editors – VS Code, Lyx , Simplenote , Laverna or Texmaker Photo, Image, Video and Audio editors – GIMP, Inkscape , Audacity , LMMS , Kdenlive , and OpenShot Screen Recording – Kazam , OBS (Open Broadcaster Software) , Flameshot or Ksnip Communication, Messaging, and Productivity Tools – Slack or Franz Virtualization options – Oracle , VM VirtualBox Authenticators - Authy Media Converters – Handbrake and SoundConverter Hardware and Software management systems – Stacer and Htop Backup Tools – Timeshift or Bacula Media Players – Audacious or VLC Media Server Software – Kodi and Plex Gamers – Steam and Discord Internet browsers - Firefox , Midori, Opera , Gnome , Google Chrome, Brave , Vivaldi , Falkon , Konqueror , Pale Moon , Waterfox , Slimjet, and Dissenter Email clients – Hiri and Thunderbird In many cases, software creators make a Linux version of the same program compatible with other operating systems. So, if you can use a computer or other electronic device, you can use Linux. ​ Nevertheless, Linux also is different from other operating systems in many significant ways. Linux is open-source software. The code used to create Linux is free and available to the public to view, edit, and for users with the appropriate skills to contribute to it. ​ Linux is also unusual in that, although the core pieces of the Linux operating system are generally common, there are many distributions (types or versions) of Linux, that include distinctive software options. Meaning, that Linux is incredibly customisable, not because applications like word processors and web browsers, can be changed, but Linux users can also choose core components, like which system display graphic or user-interface components used.

Tools Whether they be scrap build or model kits there is a vast array of tools available to make and modify models. Before deciding what tools you need, decide what type of models you are going to build, a few are: ​ Scale model building, plastic model kits, have a magnitude of types, such as: Model military vehicles, figures, and terrain. Model aircraft. Model cars, commercial, and construction vehicles. Model rockets. Naval, ship models. Architectural models, cardboard, or high-density foam buildings. Model figures or busts. Rail transport modelling (probably the most well-known). Gundam models. Scenery to stage models. So, model building is not exclusively a hobbyist pursuit. The complexity of assembling representations of actual objects has become a career for numerous people. Some build models to commemorate historic events or commissioned to construct models using past events as a basis to predict future events of high commercial interest, while others work for the film industry. ​ In the 1950-60s, a relative built live steam engine models from scratch, and I can remember watching him work. The UK has an extremely high fraternity of live steam engine modellers, partly, I think to the vast community of steam engines/traction engines in the UK. There is a basic list of tools required to build plastic scale model kits, mine is: Sprue cutters – removing items off the sprue. Finer plastic cutters – trimming off excess. Scalpel handles or hobby knife – trimming and removing mold lines, cutting decals. I prefer scalpel handles and have: Numbers 3, 4, 5, 7 and a long scalpel handle that takes N◦.20/22/24 blades. But I use mostly the size 10 blades that have a sharp point. I have medical sharps boxes for the disposal of blades. Dissecting Forceps – plain dissecting forceps, I use a variety suited to handling models and decals, such as: Atraumatic – thumb style used for grasping delicate tissue. Adson – serrated jaws with wide, flat thumb grasp area used for delicate tissue. Artery clip – used to apply and remove scalpel blades from knife handles. I use a variety, but mostly: De Bakey Forceps. Dunhill Artery Forceps. Mosquito Artery Forceps. Various pliers –non-aggressive. Scissors – straight and curved, plus special scissors for decals. Toothbrushes – fine, medium, and hard. Marking pens – various. Alligator clips placed on barbecue skewers for airbrushing. Sanding sticks – various grades. Paint - as mentioned in the paint section, water-based acrylic paint is the most commonly used to spray plastic models. Paintbrushes - sizes of models vary greatly if you are interested in Warhammer 28mm figures or painting busts a good selection of paintbrushes is vital. They range in size, from 000 up. Specialised Equipment Among my tools, I have some specialised equipment that makes life a lot easier, such as my: ​ Vortex Mixer – I have used this to mix my paint for many years and it is fantastic and a godsend (as I have arthritis in most of my joints), I have just ordered a replacement as it eventually failed, not surprising really considering the amount of use it gets. ​ Food Dehydrator – I have one that heats to 80°C but tend to run it at 70°C, it has 10 shelves and a fantastic piece of equipment, large enough to get a 1:32 tank fully built easily. If you decide to get one make sure it is large enough, the smaller plastic dehydrators will not take anything big. We also use it to dry fruit, meat, and flowers. You must let the sprayed models dry to touch (about 20 minutes) before putting them in the dehydrator. But the dehydrator will cure primer, varnish, and laquear paint in 4 hours that would normally take between 2 to 3 weeks. And when using acrylic, I have completely sprayed a tank and weathered and built it in a day. Mine is ECO friendly and uses minimal electricity, it came with 10 stainless steel and 4 plastic trays. ​ Additional Air Compressor Tank – my air compressor has a 2.5L tank, which is fine, but I purchased an additional 5L air compressor tank just to keep the noise levels down when videoing in my workshop. Nova3D Printer – I use this to print replacements for damaged model parts or when designing terrain for my dioramas. ​ Colour Laser Printer – I rarely use decals from the manufacturers who make the model kits as I find them of poor quality, so, I either airbrush the design directly onto the model or scan it onto my computer, edit it (if required) and then print them.

RAID Striping 0 to 4 RAID 0 Striping ​ With RAID 0 the data is written across multiple drives to improve access performance. There is no data redundancy. So, a 4Meg file would be written across 4 drives in 1Meg pieces. Because of this, the failure of one drive will render the data inaccessible, but the advantage is considerably higher throughput. RAID 1 (mirroring without parity or striping) With RAID 1 data is written identically to two drives, thereby producing a ‘mirrored set’. The read request is examined by either of the two HDDs containing the requested data, whichever one involves the least seek time plus rotational latency. ​ Similarly, a written request updates the stripes of both drives. The write performance depends on the slower of the two writes, such as, the one that involves a larger seek time and rotational latency. ​ At least two drives are required to constitute such an array. While more constituent drives may be employed, but many applications deal with a maximum of only two. The array continues to operate if at least one drive is functioning. Key: A, B, C, D, E, and F are blocks of data RAID 2 has bit-level striping with dedicated Hamming-code parity, all disk spindle rotation is synchronized, and data is striped so that each sequential bit is on a different drive. Hamming-code parity is calculated across matching bits and stored on at least one parity drive. ​ RAID 3 has byte-level striping with dedicated parity, all disk spindle rotation is synchronized and data are striped so each sequential byte is on a different drive. Parity is calculated across matching bytes and stored on a dedicated parity drive. ​ RAID 4 is block-level striping with dedicated parity and is equivalent to RAID 5 but all parity data is stored on a single drive. In this configuration files can be dispersed between multiple drives. Each drive operates independently allowing I/O requests to be performed in parallel. ​ RAID 2 is more of a theoretical system and not used in practice. But although applications for RAID 3 exist it is not commonly used in practice.
