Alberta Provincial Highway No. 2 referred to as Highway 2 or the Queen Elizabeth II Highway, is a major highway in Alberta that stretches from the Canada–United States border through Calgary and Edmonton to Grande Prairie. Running north to south for 1,273 kilometres, it is the longest and busiest highway in the province carrying nearly 170,000 vehicles per day in central Calgary. Between Edmonton and Fort Macleod, the highway forms a portion of Alberta's Export Highway and the CANAMEX Corridor. More than half of Alberta's 4 million residents live in the Calgary–Edmonton Corridor created by Highway 2. U. S. Route 89 enters Alberta from Montana and becomes Highway 2, a two-lane road that traverses the foothills of southern Alberta to Fort Macleod where it intersects Highway 3 and becomes divided. In Calgary, the route is a busy freeway named Deerfoot Trail that continues into central Alberta as the Queen Elizabeth II Highway, bypassing Red Deer. In Edmonton, it is concurrent with freeway sections of Highways 216 and 16 before bisecting the city of St. Albert and reverting to two lanes en route to Athabasca.

It bends northwest along the south shore of Lesser Slave Lake as the Northern Woods and Water Route into High Prairie, before turning north to Peace River, west to Fairview and south to Grande Prairie where it ends at Highway 43. Numbered as Highway 1, Highway 2 is the oldest major highway in Alberta and the first to stretch north into the Peace Country, it was known as the Calgary and Edmonton Trail, Sunshine Trail, the Blue Trail. Major changes include the construction of a divided freeway between Calgary and Edmonton in the 1960s, realignment along Deerfoot Trail in the 1980s, twinning south of Calgary in the 1990s. A Highway 43 realignment in 1998 shortened Highway 2 by nearly 90 km to its current northern terminus in Grande Prairie. Several projects including median widening and interchange upgrades have been undertaken in the 2010s to increase the safety of the highway's busier sections, with further improvements either under construction or awaiting funding. Bypasses of Fort Macleod and Nanton are planned as part of Alberta's effort to make its portion of the CANAMEX Corridor free-flowing from border to border.

Highway 2 is a core route in the National Highway System of Canada. The speed limit along most parts of the highway between Fort Macleod and Morinville is 110 km/h and in urban areas, such as through Claresholm, Nanton and Edmonton, it ranges from 50 km/h to 110 km/h. During the winter, accidents are common on the stretch of the highway between Calgary and Edmonton as the weather can change and drivers underestimate the conditions, overwhelming emergency services attempting to respond; as the main north-south access in Alberta, Highway 2 is the preferred path of the CANAMEX Corridor. Between Fort Macleod and Edmonton, Highway 2 maintains no fewer than four lanes of traffic and is a freeway between Okotoks and Edmonton, with improvements underway to eliminate the at-grade crossings that remain. Highway 2 begins at the United States border, as the two lane U. S. Route 89 crosses into Canada at Carway; the road proceeds north through the Rocky Mountain Foothills to a brief concurrency with Highway 501, before bisecting the town of Cardston.

At the north end of town, the highway enters Blood Indian Reserve No. 148 and Highway 5 splits west to Waterton Lakes National Park. Highway 2 continues north to another short concurrency with Highway 505 during which it crosses the Waterton River to Stand Off, continuing across the Belly River to Fort Macleod in the Municipal District of Willow Creek. Less than 1 km before meeting Highway 3 southeast of Fort Macleod, Highway 2 becomes a divided highway. Highway 3 splits east to Lethbridge, the combined Highways 2 and 3 turn due west through town as a divided highway at a speed limit of 50 km/h. West of town, the highways diverge at an interchange, it continues 25 km north to Granum from which Highway 519 splits to the east. In tandem with Highway 23, Highway 519 is used by CANAMEX traffic to bypass Fort Macleod. Further north on Highway 2, the towns of Claresholm and Nanton are each bisected at a reduced speed limit of 50 km/h; the highway is concurrent with Highway 533 for its brief distance through Nanton.

North of Nanton, the highway continues into the Municipal District of Foothills to a major junction with Highways 23 and 2A at High River, after which it veers northwest to cross the Highwood River. On the other side of the river, a second interchange provides access to Okotoks via Highways 7 and 2A, Highway 2 continues north across the Sheep River to De Winton where Highway 2A splits into southwest Calgary as Macleod Trail, Highway 2 veers northeast toward the Bow River valley and southeast Calgary. From its split with Macleod Trail, Highway 2 becomes a major freeway named Deerfoot Trail that descends to cross the Bow River before entering Calgary city limits. In the city it crosses jogging back and forth between its east and west bank; the freeway intersects the Stoney Trail ring road at the south end of Calgary, with signage recommending that traffic en route to Calgary International Airport and Medicine Hat use eastbound Stoney Trail as a bypass. Deerfoot Trail merges with the major routes of Anderson Road and Bow Bottom Trail.

The Rivière aux Canots Est is a tributary of the Rivière aux Canots, flowing in the unorganized territories of Lac-Achouakan and Lac-Moncouche, the Lac-Saint-Jean-Est Regional County Municipality, in the administrative region of Saguenay–Lac-Saint-Jean, in the province of Quebec, in Canada. The course of the Rivière aux Canots Est crosses the Laurentides Wildlife Reserve; the valley of the Rivière aux Canots Est is served indirectly by the route 169. This valley is served by a few secondary forest roads for forestry and recreational tourism activities. Forestry is the main economic activity in this valley; the surface of the Rivière aux Canots Est is frozen from the beginning of December to the end of March, however the safe circulation on the ice is done from mid-December to mid-March. The main watersheds neighboring the Rivière aux Canots Est are: north side: Suzor-Côté lake, Bousquet lake, Pikauba River, Pika River; the Rivière aux Canots Est rises at Lac Bonjour in a forest area in the Laurentides Wildlife Reserve.

This lake is fed by the outlet from Lake Calderly and the outlet from Lac des Hannetons. This source is located at: 1.7 kilometres south-west of route 169. From its source, the Rivière aux Canots Est flows over 10.2 kilometres with a drop of 109 metres in the forest zone, according to the following segments: 1.4 kilometres to the south by collecting the discharge, to the Gauthier stream. Note: the first half of this segment is in the marsh area. Note: This lake receives the discharge from Bergeron stream on the south side; the Rivière aux Canots Est flows into the northeast bank of the Rivière aux Canots. This confluence is located at: 1.4 kilometres north-west of Lac Lampron. From the mouth of the Rivière aux Canots Est, the current successively follows the course of the Rivière aux Canots on 24.1 kilometres west, the course of the Rivière aux Écorces on 52.8 kilometres north, the course of the Pikauba River on 10.6 kilometres north, crosses Kenogami Lake on 17.6 kilometres north-east to barrage de Portage-des-Roches follows the course of the Chicoutimi River on 26.2 kilometres to the east the northeast and the course of the Saguenay River on 114.6 kilometres east to Tadoussac where it merges with the Saint Lawrence estuary.

The toponym "Rivière aux Canots Est" was formalized on December 5, 1968 at the Bank of Place Names of the Commission de toponymie du Québec.

Quilt is a software utility for managing a series of changes to the source code of any computer program. Such changes are referred to as "patches" or "patch sets", Quilt takes an arbitrary number of patches and turns them into a single patch. In doing so, quilt makes it easier for other programmers to test and evaluate the different changes before they are permanently inserted into the source code. Tools of this type are important for distributed software development, in which many programmers collaborate to test and build a single large codebase. For example, quilt is used by the maintainers of the Linux kernel. Quilt evolved from a set of patch-management scripts written by Linux kernel developer Andrew Morton, was developed by Andreas Grünbacher for maintaining Linux kernel customizations for SuSE Linux, it is now being developed as a community effort, hosted at the GNU Savannah project repository and distributed as free software. Quilt's name originated from patchwork quilt. Quilt has been incorporated into dpkg, Debian's package manager and is one of the standard source formats supported from the Debian "squeeze" release onwards.

This source format is identified as "3.0" by dpkg. Quilt is integrated into the Buildroot, notably used by OpenWrt. Quilt is integrated into and supported by the similar Yocto Project build system supported by the Linux Foundation. Mercurial queues, as an extension of the Mercurial revision control system, provides similar functionality. Apache Subversion Git Official website Quilt Tutorial
