Finland Ylläs, Finland, well what can I say. If it is good skiing you want, it is not the best location to consider. I skied one day in two weeks if you can call it skiing. I eagerly made my way to the first slope in a thirty mile an hour wind and a blistering -42° (without the wind-chill) that froze my eyelids, I got off the lift and…waited, waited, and waited. At least a forty-degree incline and I was still stuck to the snow like glue to wood and ended up poling myself down the slope and worked up a greater sweat than running a marathon. Needed a drink after that run, not tea or coffee either. Meanwhile, my two mates were skiing one of the other three slopes. There are more than four runs, but most were closed because of the high winds. Out of gallery However, I can recommend the scenery, hospitality, husky safaris, and ski bike tours. Make sure you shop around as prices vary considerably. I managed to get a husky ski bike tour to a husky site and then a husky safari for the afternoon. We left at 1030 hours and arrived back about 1900 hours, so a full day for less than other companies was charging for a four-hour husky ride. The food was fantastic, if expensive, but once your there they have you, so you must cough up or stay in your accommodation all evening. Pete and I eat out every evening, but Chris tended to eat in. There is a nice supermarket, and the prices are good so if you’re on a budget eat in. The three of us found a fantastic chapel where Chris recited one of his compositions on the piano much to the pleasure of the locals. Pete and I talked to the woman who looked after the chapel. She was rightly proud of Saint Laurent chapel. It is a modern wooden design that hosts Christmas concerts with its innovative architecture and acoustic resonance. The chapel bell has its own structure outside of the chapel, an innovative design. We went in March and the temperature varied from -32 to -46. Our log-cabin had under-floor heating and a great log burner, so we were more than comfortable. It even had a clothing and ski boot warmer.

Growing Orchids Η καλλιέργεια ορχιδέων εξαρτάται επιτυχώς από τον τύπο του κλίματος που είναι το αυθεντικό. Η αναπαραγωγή των συνθηκών υπό τις οποίες το φυτό χρησιμοποιείται στη φυσική του κατάσταση είναι ζωτικής σημασίας για τη διασφάλιση της επιτυχίας. Ωστόσο, τα υβρίδια είναι πιο προσαρμόσιμα από τους γονείς τους και θα ανέχονται καταστάσεις που διαφέρουν από τους γονείς τους. Οι ορχιδέες προσαρμόζονται σε μία από τις τρεις ζώνες ή τις ζώνες θερμοκρασίας, σε σχέση με το πού μεγαλώνουν, θυμηθείτε ότι ενώ μια ορχιδέα μπορεί να προέρχεται από μια ζεστή χώρα, μπορεί να αναπτυχθεί σε υψηλό υψόμετρο και χρειάζεται θερμοκρασία χαμηλότερη από εκείνη που κανονικά θα συσχετίζεται με αυτό μέρος του κόσμου. Ζώνες θερμοκρασίας Οι ζώνες αναφέρονται ως δροσερές, ενδιάμεσες και ζεστές. Ορισμένες ενδείξεις ως προς τη ζώνη θερμοκρασίας μιας ορχιδέας μπορεί να συγκεντρωθεί από τα φύλλα - τα δροσερά φυτά που αναπτύσσονται έχουν λεπτά φύλλα - οι θερμότερες ορχιδέες που αγαπούν έχουν παχιά σαρκώδη φύλλα - φυσικά υπάρχουν εξαιρέσεις σε αυτόν τον κανόνα, οπότε να είστε προσεκτικοί. Δεν αρκεί η παροχή κλίματος ζέστης και κρύου, πρέπει επίσης να ληφθεί υπόψη το φως του ήλιου που πέφτει στο φυτό. Γενικά οι περισσότερες ορχιδέες χρειάζονται σκιά από το άμεσο ηλιακό φως και καλή κυκλοφορία του αέρα, όπως και κάθε άλλη μορφή ζωής. Πολύ ελαφρύ ηλιακό έγκαυμα των φύλλων σε κίτρινο ή σκούρο κόκκινο, όχι αρκετό φως οδηγεί σε σκούρο πράσινο φύλλωμα και χωρίς λουλούδια. Απαιτείται σκίαση τουλάχιστον 60% την άνοιξη και το καλοκαίρι και πιθανώς ακόμη και μέχρι το φθινόπωρο εάν ο καιρός είναι καλός και ζεστός.

Χρήση υπολογιστή Pascal is a general-purpose, high-level language that was originally developed for teaching programming as a systematic discipline and to develop reliable and efficient programs. ​ Pascal is an Algol-based language and includes many constructs of Algol and Algol 60 is a subset of Pascal. Pascal offers quite a few data types and programming structures, making it is easy to understand and maintain Pascal programs. ​ Pascal is widely used in the teaching and academics arena for a few reasons: ​ Easy to learn. A structured language. Produces clear, efficient, and reliable programs. Can be compiled on a variety of computer platforms ​ Pascals features: ​ Pascal is a strongly typed language. Offers extensive error checking. Provides several data types like arrays, records, files, and sets. Provides a variety of programming structures. Supports structured programming through functions and procedures. Supports object-oriented programming. So why use Pascal? It allows programmers to define complex structured data types, build dynamic and recursive data structures like lists, hierarchies, search options, calculations, or graphs.

Canmore Alberta’s Rockies Canmore is between Calgary and Banff. It took about 1½ hours to get the 50 miles (81 kilometres) from Calgary International Airport. ​ Canmore is only minutes away from Banff National Park, Kananaskis Country and Bow Valley Provincial Parks where 5 famous ski resorts and 6 breath-taking golf courses are located. ​ Canmore is situated in the Bow Valley within Alberta’s Rockies, it is an old mining town; because of this, it went relatively unnoticed for a great number of years, unlike Banff. ​ However, Canmore is more than a ski resort base. It offers over 70 kilometres of trails, a Nordic centre, hiking, climbing, mountain biking, kayaking, canoeing, rafting, and scrambling provide an endless assortment of outdoor activities. ​ To enhance your experience of the Rockies, visit the Rafter 6 ranch resort (currently up for sale), this ranch has a colossal variety of activities and the location is second to none. While there I was lucky enough to view the white buffalo, a herd of elk and some precious wolves. Being an ardent photographer, I was lucky enough to get some great photographs of the white buffalo, elk, wolves, and landscape in and around Canmore and Banff National Park. ​ Canmore's town’s elevation is 4296 feet (1309 metres) with the surrounding summits extending to heights of 9,633 feet (2936 metres). The Bow River flows through the town linking it to a network of wildlife corridors and trails. An abundance of local wildlife, wildflowers and mountains provide boundless opportunities to experience nature and take photographs of the wildlife, flora and The Three Sisters. The Three Sisters ​ The Three Sisters are a trio of peaks near Canmore. They are known individually as Big Sister (Faith), Middle Sister (Charity), and Little Sister (Hope). ​ Albert Rogers, a nephew of Major Rogers who discovered ‘Rogers Pass’ in the Selkirk Mountains named the three peaks in 1883. ​ Albert Rogers recollected, ‘there had been a heavy snowstorm in the night, and when we got up in the morning and looked out of the tent, I noticed the three peaks had a heavy veil of snow on the north side, and I said to the boys, ‘Look at the Three Nuns.’ They were called the Three Nuns for quite a while but later were called the ‘Three Sisters’ and first appeared on George Dawson’s map in 1886. ​ Heights: Big Sister (Faith) – 9,632 feet, (2,936 metres) Middle Sister (Charity) - 9,084 feet, (2,769 metres) Little Sister (Hope) - 8,840 feet, (2,694 metres) Out of gallery History In 1884 Donald Smith the director of the Canadian Pacific Railway officially named Canmore. In 1886, Queen Victoria granted a coal mining charter to the town, and the first mine was opened a year later. In the 1890s a North-West Mounted Police barrack had been built on Main Street, but it was vacated in 1927 and was restored in 1989. It still remains in the main street. ​ By the 1970s the market for coal had diminished and in 1979 the Canmore mines ceased operations. Unfortunately because of safety and reclamation policies initiated by the province of Alberta, most of the mining structures were demolished and today, only the lamphouse and a few mine entrances remain. Canmore’s commercial future seemed gloomy until the announcement in the 1980s that Calgary would be hosting the 1988 Winter Olympics. This opened the door for Canmore, as it would host the Nordic events, resulting in increased tourism.

Motherboard A motherboard, system board, or colloquially, a mobo is a printed circuit board (PCB) found in computers and other expandable systems. ​ All motherboards have socket name that corresponds with the CPU that can be used, a few are: ​ AMD AM3+, AMD Ryzen™ and AMD FX Intel i7 series LGA 1156 socket H Intel i9 - LGA 2066 A Motherboard holds a few crucial components, such as, ​ Central Processing Unit or the CPU socket. Memory (RAM) slots. Contains important sub-systems . Many have embedded HD video facilities and 7:1 sound . Holds the BIOS (Basic Input Output System) installed. Provides connectors for peripherals, sockets, connections, and slots for: ​ Mouse Keyboard Speakers Network port USB ports Firewire port Hard drives Monitor Video cards Sound cards Network cards TV Tuner cards Motherboards provide several external connections, so users are able use the computer. It is PCB with expansion capability - the board is the ‘mother’ of most of the components attached. Different types of motherboard ports and their functions explained. ​ RJ-45 (Registered Jack 45) LAN port – The RJ-45 port allows connection to a Local Area Network (LAN) through a network hub using an RJ-45 cable. ​ Analog Audio P orts – allow connections like speakers, audio devices, and microphones. ​ USB (Universal Serial Bus) 2.0 or 3.0 Ports - are located on each motherboard and used for connecting mice, keyboards, printers/scanners, external hard drives, and tablets. ​ PS/2 Keyboard Port (purple) - used for a PS/2 keyboard. PS/2 mouse port (green) - used for a PS/2 mouse. ​ 1394a Port - used to connect firewire devices. FireWire has largely been displaced by USB. However, some professional audio hardware devices still use FireWire. ​ Optical S/PDIF - used for sound connections to home audio receivers or powered PC speakers with optical connections. ​ eSATA Port (External Serial Advanced Technology Attachment) - It is an external interface for SATA technologies and competes with FireWire 400 and USB 2.0 to provide fast data transfer speeds for external storage devices. ​ HDMI Port (High-Definition Multimedia Interface) - is a digital interface for transmitting audio and video data in a single cable. It is supported by most HDTVs and related components, like DVD and Blu-Ray players, cable boxes, and video game systems. ​ DVI Port (Digital Visual Interface) - is used to send digital information from a computer to a digital display, such as a flat-panel LCD monitor. There are several types: ​ DisplayPort (DP) - is a digital display interface developed by a conglomerate of PC and chip manufacturers. The interface is primarily used to connect a video source to a display device, a monitor, it can also carry audio , USB , and other forms of data. Initially, the DisplayPort was designed to replace VGA, FPD-Link, Digital Visual Interface (DVI), and the interface is backward compatible with HDMI and DVI, using adapters. ​ VGA (Video Graphics Array) Port - VGA is an older video format and it allows an analog signal as opposed to a digital signal (ones and zeroes). Using higher frequencies, it is possible to reach a relatively high range of video resolutions. However, video quality directly responds to cable quality, and particularly with higher resolutions. Because of this, the quality of a VGA image can fluctuate with different makes of cable. ​ ​ Bus Sub-Systems The motherboard is a circuit board that connects the CPU to the memory and all the other hardware. Buses are circuits on the motherboard that connect the CPU to other components. There are many buses on the motherboard, bus systems move instructions and data around the system. Bus speed is measured in megahertz (MHz), The faster the bus, the quicker data is communicated, therefore, the motherboards speed is defined by the bus speed. ​ Bus systems are limited by their width in bits and are usually 8, 16, or 32-bits wide. This indicates how many bits can be sent by the bus at any one time, so, a 32-bit bus can send 32 bits or a 16-bit can send 16 bits at once. ​ The bus that connects the CPU to the memory is called the front-side bus (FSB) or system bus. CPU cores share Level 2 and Level 3 cache across the front-side bus and will usually connect to Level 2 cache through the back-side bus (BSB), the back-side bus is faster than the FSB. ​ There are two types of Bus sub-systems: ​ Internal – Buses that connect to internal components. ​ External – Buses that connect to external components. ​ The FSB contains two types of bus: ​ Address bus - this sends information about where data needs to go by sending an address to the memory. The address bus only sends data in one direction - from the CPU to RAM. ​ Data bus - this sends data to the memory or receives data from the memory. Data can flow both ways along the data bus. ​ ​ A Bus Sub-system transfers data between computer components. Separate to point-to-point connections, a bus system can logically connect several peripherals over the same set of connections. ​ Every Bus defines its set of connectors to physically plug devices, cards, or cables together. Because of this, there are various kinds of slots used to connect internal and external devices. North Bridge : The northbridge typically handles communications among the CPU, in some cases RAM, and PCI Express (or AGP) video cards, and the southbridge. Northbridge is directly connected to AGP video, thus providing higher transfer rates. SouthBridge : The southbridge is one of the two chips in the core logic chipset on a personal computer (PC) motherboard, the other being the northbridge. The southbridge typically implements the slower capabilities of the motherboard in a northbridge/southbridge chipset computer architecture. A southbridge chipset handles all the computer's I/O functions, such as USB, audio, serial, the system BIOS, the ISA bus, the interrupt controller, and the IDE channels. PCI (Peripheral Component Interconnect) There are many kinds of internal buses, but there are only a few popular ones. Various motherboards have different kinds and a number of slots, so it is vital to know what kind and number of slots a motherboard has before purchasing a sound or video card and match the type of slot to the motherboard. ​ PCI (Peripheral Component Interconnect) was common in PCs several years ago, now PCIe (Peripheral Component Interconnect Express) has succeeded this type of bus. Usually, PCIe cards used were: ​ Network card or NIC card Sound card Modems Additional USB or Serial ports TV tuner card Additional SATA disk controllers Video card ​ PCIe (Peripheral Component Interconnect Express) PCIe was designed to replace the general-purpose PCI expansion bus and the aging AGP graphics card interface. PCIe is not a bus, but a point-to-point connection of serial links called lanes. Because PCIe cards have faster bandwidths than PCI cards they make an ideal option for high-end video cards. ​ AGP (Accelerated Graphics Port) AGP (Accelerated Graphics Port) is a high-speed point-to-point channel for attaching graphics cards to motherboards to help in the acceleration of 3D graphics. Connectors and Motherboard Pins Motherboards require connectors and Pins to work. Some power the motherboard, while others provide connections for: ​ SATA and IDE (old type connection) Hard drives SATA and IDE DVD/CD writers/players and IDE floppy drive (no longer used) USB, Firewire, Audio (analog and digital), connections for the front of the case, and DVD players Power for fans (including the CPU cooling fan) ATX 24 pin and ATX 6 12-volt motherboard power Front panel pins – computer cases have fitted leads for front USB, Firewire, audio, microphones and: Power Switch Speaker Reset Switch Power LED Chassis Intrusion Header Hard drive activity LED Message/Power Sleep LED ​ Front panel pins are a conundrum because case manufacturers have not decided on a standard. Some manufacturers use plain coloured wire, others dual coloured and they hardly ever identify with is positive or ground leads. If lucky they put an information sheet in the box, but the cheaper cases tend not to have these. ​ Luckily, some motherboard manufacturers are more accommodating. However, all manufacturers do indicate which lead is which by abbreviating on the connector, such as: ​ PWR – Power Switch SPK - Speaker RES - Reset Switch MSG - Message/Power/Sleep LED CH - Chassis Intrusion Header HD - Hard drive activity LED PWR LED ​ The pin assignments for the front panel header may differ by model. Refer to the motherboard user's manual for the actual pin assignments.

Χρήση υπολογιστή What are Computer programming languages? Computer programming languages allow us to give instructions to a computer in a language the computer understands. Many human languages exist, there is also an assortment of Computer programming languages that programmers use to communicate with a computer. The portion of the language that a computer can understand is called a Binary. Translating programming language into binary is known as Compiling. Every language, from Pascal, C++, or Python, has its own distinctive features, although there are numerous similarities between each programming language. Computer languages permit computers to process large and complex lines of information rapidly and efficiently. There are lots of programming languages used in the industry today.
