3000, 5000, 7000 Series (2015–current)

Dell-Latitude Series

Dell announced a new series of Latitude laptops in August 2013: the 3000 series, the 5000 series and the 7000 series. In October 2015, Dell announced the first generation of Precision mobile workstations of this series with model numbers 3510, 5510, 7510 and 7710. In January 2017, Dell announced the second generation laptops in this series with model numbers 3520, 5520, 7520 and 7720. In April 2018, Dell announced the third generation of laptops in this series with model numbers 3530, 5530, 7530 and 7730. In May 2019 Dell announced the 4th Generation of the 55xx and 7xxx series mobile workstations with the release of the 5540, 7540 and 7740 models.

All first generation (xx10) Precision Series

Dell Precision laptops (except the 5510) are compatible with the E-Series Advanced Port Replicators. The second generation (xx20) Precision laptops support the E-Series docking station for the 7520 and 7720 models, but not for the 3520 and 5520 models. The third generation (xx30) Precision laptops no longer support the E-Series docking station.

Latitude E Series based (2008-2014)[edit]

Precision M4500

Dell launched the E Series of laptops on August 12, 2008 with a collection of Latitude (E4200, E5400, E5500, E6400, E6500, E6400 ATG/XFR) and Precision (M4400, M2400) computers.^[29] Both the Latitude and Precision computers are compatible with the new E Series docking stations (E-Port and E-Port Plus). Notably, the 17" models do not share a chassis with the Inspiron series anymore, and starting with the M4600 the 15" Precisions do not share a Latitude chassis either. QHD, UHD and RGBLED IPS models have a disabled iGPU. This has several downsides: the power consumption during low load is high and thus the battery runtimes clearly suffer despite the high-capacity battery, and Intel's QuickSync Video cannot be used. AMD GPU equipped models before the M4800/M6800 also do not support AMD Enduro Switchable Graphics.

Latitude D Series based (2003-2007)[edit]

These Precision models were released at roughly the same time as their D-series Latitude counterparts. They are compatible with the D-series docking stations, and there are various accessories that are interchangeable with other Dell models, such as the battery or CD drive, depending on the Precision model. Some of these models (especially those made around ~2005-2007) with NVIDIA GPUs can suffer from GPU failure.

How fungi contribute to the ecosystem

 

 

Mycelium - The Future is Fungi

Mycelium - The Future is Fungi

They were here first...

Did you know that long before trees overtook the land, earth was covered by giant mushrooms. Researchers found that land plants had evolved on Earth by about 700 million years ago and land fungi by about 1,300 million years ago. The largest living organism in the world today is a honey fungus measuring 2.4 miles (3.8 km) across in the Blue Mountains in Oregon. 

 

So what's so special about fungi and how do they contribute to the ecosystem?

Fungi play an important role in energy cycling within, and between, ecosystems. Fungi are found in terrestrial, marine and freshwater environments, and are part of a diverse community of “decomposers” that break down dead plants and animals. Aside from fungi, this community includes bacteria, tiny invertebrates, such as nematodes, and larger invertebrates, like snails, beetles and earthworms. Fungi transform organic matter into forms that can be utilized by other decomposers, and into food for plants.

DECOMPOSITION

Fungi live everywhere that moisture is present. They can be found as single-celled organisms, like yeast, that are invisible to the naked eye, and as multiple-celled organisms, like mushrooms, that are made up of strands of cells called “hyphae.” Fungi are so widespread and numerous that they make up a large proportion of the biomass in any given ecosystem. Fungi play a very important part in the decomposition process, because they can break down tough organic materials, such as cellulose and lignin, which invertebrates find difficult to digest. Fungi release digestive enzymes that are used to metabolize complex organic compounds into soluble nutrients, such as simple sugars, nitrates and phosphates. Unlike animals, that digest food inside their bodies, fungi digest food outside of their “bodies” and then absorb the nutrients into their cells.

NUTRIENT CYCLING

Plants require nutrients for growth, but nutrients are seldom freely available in soil or water because they are locked up in insoluble compounds. Plants therefore rely on decomposers to provide them with soluble nutrients that can be taken up by roots. For instance nitrogen, one of the most important plant nutrients, is locked into proteins that are not easily taken up by plants -- although some plants have been shown to do so. Fungi metabolize proteins, and release inorganic forms of nitrogen, such as nitrate, that can easily be taken up by plant roots. In freshwater environments fungi are instrumental in the transfer of energy from riparian forest to aquatic ecosystems, by decomposing wood and leaf litter that fall into the water. In terrestrial systems, fungi transfer energy from above the ground, to below it, where it is recycled back to plants.

SYMBIOSIS

Some species of fungi form symbiotic relationships with plants. Mycorrhizal fungi are associated with plant roots. This relationship is mutually beneficial because fungi facilitate the transfer of nutrients from the soil into plant roots, and in turn receive carbon from the plant. Carbon is stored by fungi in the soil and therefore is not released as carbon dioxide. It was once thought that plants were the only source of carbon for mycorrhizal fungi. However, an article published in the May 2008 issue of “Functional Ecology” reveals that mycorrhizal fungi can actively decompose organic carbon, and therefore play a greater role in carbon loss and input from soil than previously thought. Lichens are another type of fungi that form a symbiotic relationship, but they do so with cyanobacteria. Lichens provide shelter for the bacteria, which in turn make energy and carbon for lichens via photosynthesis.

FOOD SOURCE

There are many animals that rely partially, or wholly, on fungi as a food source. Herbivorous mammals tend to be opportunistic fungus feeders, eating fungi if they come across it while browsing in the forest. However, for some animals fungi makes up a large part of their diets. Examples are the caribou, which relies heavily on tree lichens for food during the winter when leafy foods are not available, and the long-nosed potoroo, an Australian mammal whose diet consists almost entirely of fungal fruiting bodies. Many invertebrates also eat fungi, both opportunistically and actively. Stream invertebrates receive extra energy when they eat decaying leaves that have fungi growing on them. Banana slugs are commonly observed feeding on mushrooms and other fungi, which they appear to favor over other foods.

The discipline of biology devoted to the study of fungi is known as mycology. Mycelium is the vegetative part of a fungus, consisting of a network of fine white filaments (hyphae) .

What is Mycelium?

The word mycelium literally means “more than one”. It is actually a plural form of the word Mycelia.  The word has New Latin and Greek origins and was first coined in text in the early 1800’s, and refers to the thread-like body of a fungus.  The main part of the fungus is the mycelia, which lives inside the substrate (wood, straw, grain, etc). The mushrooms that we eat are actually just a small visible part of the organism. In nature mushrooms "bloom" much like flowers do.  Like flowers, mushrooms bloom during certain times of the year when the conditions are just right.  To properly explain mycelium we have to get a little technical.

Mushrooms do not reproduce by seed or gather energy by photosynthesis like plants do.  They reproduce by means of spores.  These spores germinate to produce a mass of interwoven, single-cell wide structures known as hyphae.  Hyphae are sometimes also called Shiro.  Collectively, masses of hyphae are known as the mycelium. 

Fungus absorbs nutrients from its environment (substrate, log, etc) through its mycelium in a two-stage process.  First, the hyphae secrete enzymes into the decaying wood or other substrate. These enzymes break down biological polymers into smaller units such as monomers.   The mycelium then absorbs these monomers, using a combination of facilitated diffusion and active transport. 

Just like an apple on a tree the mushroom is a fruit of these reproducing fungi.  In nature the chances of mushroom spores germinating and then actually producing a mushroom are quite slim.  Everything has to be just right to actually produce a mushroom.  They don’t just grow everywhere at random.  This is why mushrooms are highly prized and hunted in the wild.  In our sterile laboratory however we can produce mushrooms that are free of contaminates.  Our mycologists cultivate a select species indoor where the mushroom mycelium can grow without the harsh environment nature sometimes provides.  

Cultures can be taken from spores or from the mushroom tissue itself.  In the process of germinating spores, many different strains are formed.  All strains however are not compatible with each other. In taking a culture from the tissue of a living mushroom, the cultivator preserves the exact genetic character of that specific mushroom.  This is also known as cloning.  When spores are used, a single strain must be singled out from the vast array of strains created.  In both cases, the end result is basically a network of cells.  This is the amazing mycelium, the actual organism that produces mushrooms.

Stop, observe and learn from mother nature, for she has an answer to everything.

Mycelium-Mushroom-Visions/Poem:
I have mushrooms growing on my "ceiling", each look like a "cherry", I give these mushroom "merit", reminds me of a psychedelic "bus", of course I am the "general" on this bus, there is also no "rent", mycelium is has a special foot-"print", many other mushrooms are "useless", I pick them from the "rural" regions, they are never "under" my feet, thereis a great "market" for mycelium in china, I always "discover" new mycelium locations,

It works!

'This is the Apache2 Defualt Index.html File Welcome Ppage' used to test the correct operation of the Apache2 server after installation on Ubuntu systems. It is based on the equivalent page on Debian, from which the Ubuntu Apache packaging is derived. If you can read this page, it means that the Apache HTTP server installed at this site is working properly. You should replace this file (located at /var/www/html/index.html) before continuing to operate your HTTP server.

If you are a normal user of this web site and don't know what this page is about, this probably means that the site is currently unavailable due to maintenance. If the problem persists, please contact the site's administrator.

Configuration Overview: 

Ubuntu's Apache2 default configuration is different from the upstream default configuration, and split into several files optimized for interaction with Ubuntu tools. 

The configuration system is fully documented in /usr/share/doc/apache2/README.Debian.gz

Refer to this for the full documentation. Documentation for the web server itself can be found by accessing the manual if the apache2-doc package was installed on this server.

The configuration layout for an Apache2 web server installation on Ubuntu systems is as follows:

/etc/apache2/
|-- apache2.conf
|       `--  ports.conf
|-- mods-enabled
|       |-- *.load
|       `-- *.conf
|-- conf-enabled
|       `-- *.conf
|-- sites-enabled
|       `-- *.conf
          

• apache2.conf is the main configuration file. It puts the pieces together by including all remaining configuration files when starting up the web server.
• ports.conf is always included from the main configuration file. It is used to determine the listening ports for incoming connections, and this file can be customized anytime.
• Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/ directories contain particular configuration snippets which manage modules, global configuration fragments, or virtual host configurations, respectively.
• They are activated by symlinking available configuration files from their respective *-available/ counterparts. These should be managed by using our helpers a2enmod, a2dismod, a2ensite, a2dissite, and a2enconf, a2disconf . See their respective man pages for detailed information.
• The binary is called apache2. Due to the use of environment variables, in the default configuration, apache2 needs to be started/stopped with /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not work with the default configuration.

 

 

 Document Roots:  

 

By default, Ubuntu does not allow access through the web browser to any file apart of those located in /var/www, public_html directories (when enabled) and /usr/share (for web applications). If your site is using a web document root located elsewhere (such as in /srv) you may need to whitelist your document root directory in /etc/apache2/apache2.conf.

The default Ubuntu document root is /var/www/html. You can make your own virtual hosts under /var/www. This is different to previous releases which provides better security out of the box.

Reporting Problems

Please use the ubuntu-bug tool to report bugs in the Apache2 package with Ubuntu. However, check existing bug reports before reporting a new bug.

Please report bugs specific to modules (such as PHP and others) to respective packages, not to the web server itself.
