Black Widow V6 Crackberry

The BlackWidow is an icon in the world of PC Gaming. It's also one of the products that put Razer on the map, and nine years later the name still holds respect and desire the world over.

I would expect BlackBerry's deal to have access to Samsungs boot loader keys would permit you to reinstall Samsung's Android to have any service done by Samsung, return during the grace period or to sell it used. Of course I would hope support for Link and Blend would resume. I was able to load. Find used car at the best price. We have 68 cars for sale for black widow truck, from just $2,800.

In 2019 you can get your hands on three current models to bear the legendary name, and it's a good looking product line. There is an entry model, a mid-ranger, and a bells and whistles range-topping Elite model.

What we have in front of us today is the entry model, the BlackWidow Lite. And on balance it's probably the best of the bunch.

Absurdly good

Razer BlackWidow Lite

Bottom line: Everything you need, nothing you don't, and it doesn't cost a lot.

Pros:

• Compact design
• Removable cable
• Quiet orange switches
• Hypershift support for macros
• Included O rings for added silence

Cons:

• No number pad
• Feet don't provide much angle
• No RGB

The BlackWidow Lite also comes in a limited edition Star Wars finish.

The BlackWidow Lite is a tenkeyless design, harking back to the previous generation BlackWidow Tournament Edition a little. It's incredibly compact, and despite having so little heft to it, is solid and feels well made.

The keyboard uses Razer's orange switches, which you can see simply by looking along the exposed bases. Orange switches are a lot quieter than Razer's traditional green switches, lacking the loud clack and making the BlackWidow Lite a little more pleasant to type on in an office environment.

Razer's orange switches are quiet..and fast

It's not just the sound, either, that differ between orange and green. Orange switches require less actuation force, and less overall to hit bottom. You get the same overall travel from an orange switch as you would the greens on the regular BlackWidow, but it feels lighter and faster to use, particularly for typing.

And despite being quieter, the orange switches aren't silent. They're far from as loud as you'll get on the other BlackWidow keyboards, but there's still something of a clack, and it's quite satisfying. If you're going for as little noise as possible, Razer includes a bag of O rings, enough to equip the entire keyboard with further sound dampening.

Do they make a difference? A little, there's a definite change in the sound, but personally, I prefer the BlackWidow Lite without them. But you've got the option, and if you need as much quiet as possible, they're useful to have.

With or without additional dampening, the BlackWidow Lite is simply superb to type and game on. The tactile feedback isn't quite as fierce as you'll find on the regular BlackWidow, but I'm a big fan, and typing on this compared to its bigger brother has been a more pleasant experience. It feels faster thanks to the lighter pressure required to actuate the keys, and it's as good for getting work done as it is for gaming on.

One of the BlackWidow Lite's other strong points is how portable it is. If you travel a lot and want a keyboard you can take with you to use with your gaming laptop; this is the one. The cable is detachable, and it's so small and light that packing it into a backpack will be an absolute breeze.

And if you're a Star Wars fan, you can also snag the BlackWidow Lite in a limited edition Stormtrooper guise. Otherwise, it's available in any color you like so long as it's black.

The BlackWidow Lite also gets the benefit of Razer's Hypershift through the Synapse 3 companion application. There's not much to do here with lighting (more on that below), but Hypershift allows you to add macros and custom functions to any key on the keyboard for quick access.

Download stickman games. It lacks onboard storage, so you'll always need to have Synapse close by if you travel, but no matter what you need to add, you can do so with the BlackWidow Lite.

What you'll dislike about the Razer BlackWidow Lite

For a keyboard, this good is there really anything to dislike? There are a few things that might be offputting depending on your outlook.

The first is that, obviously, there's no number pad here. For me, that's fine, I never use one anyway. But if you're one of those who has to have it, then you'll need to step up to the regular BlackWidow.

If you're all-in on Chroma you're going to be disappointed

More likely of concern is the shallow angle provided by the legs on the BlackWidow Lite. The difference between totally flat on the desk really could be a little steeper. It's fine for me, but it's something to consider if you like a steep angle on your keyboard.

It's also perhaps a little surprising that the BlackWidow Lite doesn't have Razer Chroma. It seems like everything the company makes these days has Chroma, and Chroma is integrated with so many games, apps, and smart home devices. But all you get here is a single white backlight, and a green variation on the Caps Lock key when it is turned on.

Is missing RGB really a con though? If you're all-in on Chroma, then the lack of it might put you off a little since you can't integrate the keyboard with the rest of your setup. If you're absolutely set on wanting Chroma, you'll need the regular BlackWidow which has it.

I think the white illumination on the BlackWidow Lite is pretty stylish and does what I want from it most: Illuminates the keys.

Should you buy the Razer BlackWidow Lite?

The BlackWidow Lite, despite being the cheapest of the family, is the one to get unless you absolutely must have RGB lighting or a number pad. I was using the regular 2019 BlackWidow. Now I've switched to this and won't be switching back in a hurry. I prefer the size, the removable cable, the switches, everything.

It's simple, but it has everything you need in a good keyboard. The orange switches are so, so good, and during non-gaming tasks, it's definitely the nicer to type on than its bigger brothers. I like a good clack from my keyboard, but there's still enough here to satisfy.

The BlackWidow Lite is the keyboard to get

It's ultimately a very thoughtfully designed keyboard. The switches used here offer a genuine alternative to the traditional, clicky greens, and Razer hasn't cut out anything truly important in keeping the cost of the BlackWidow Lite down.

At under $100 this is easily one of the top keyboards you can get right now if you're looking for work, play or both. It does what you need it to do, and does it well, no fluff. It's absolutely fantastic.

Absolutely brilliant

January's 'Patch Tuesday' updates arrive with important security fix

The official 'Patch Tuesday' updates are here for January, and they include an important fix for a spoofing flaw across most versions of Windows 10. As usual with these updates, there are no new features to check out.

Latrodectus mactans, known as southern black widow or simply black widow, and the shoe-button spider,^{[citation needed]} is a venomous species of spider in the genus Latrodectus. The females are well known for their distinctive black and red coloring and for the fact that they will occasionally eat their mate after reproduction. The species is native to North America. The venom is seldom fatal to healthy humans.^[2]

Taxonomy[edit]

Latrodectus mactans was first described by Johan Christian Fabricius in 1775, placing it in the genus Aranea.^[1][3] It was transferred to the genus Latrodectus in 1837 by Charles Walckenaer and is currently placed in the Theridiidae family of the order Araneae.^[1] The species is closely related to Latrodectus hesperus (western black widow) and Latrodectus variolus (northern black widow). Members of the three species are often confused with the genus Steatoda, the false widows. Prior to 1970, when the current taxonomic divisions for North American black widows were set forth by Kaston,^[4] all three varieties were classified as a single species, L. mactans. As a result, there exist numerous references which claim that 'black widow' (without any geographic modifier) applies to L. mactans alone. Common usage of the term 'black widow' makes no distinction between the three species.

Description[edit]

The body length (excluding legs) of the mature female is 8–13 mm (0.31–0.51 in), 3–6 mm (0.12–0.24 in) for males. Legs are long in proportion to body.^[5] Females are shiny and black in color, with a red marking in the shape of an hourglass on the ventral (under) side of her very rounded abdomen.^[6] There is much variation in female size, particularly in egg-carrying (gravid) females. The abdomen of a gravid female can be more than 1.25 cm (0.5 in) in diameter. Many female widows also have an orange or red patch just above the spinnerets on the top of the abdomen.^[7] Juveniles have a distinctly different appearance from the adults; the abdomen is grayish to black with white stripes running across it and is spotted with yellow and orange.^[7] Males are either purple, or closer to the appearance of the juveniles in color.

The web of the black widow spider is a three-dimensional tangled cobweb of exceptionally strong silk.^[8]

Range[edit]

The southern widow is primarily found in (and is indigenous to) the southeastern United States, ranging as far north as Ohio and as far west as Texas.^[9] The northern black widow (L. variolus) is found primarily in the northeastern United States and southeastern Canada, though its range overlaps with that of L. mactans. In Canada, black widows range in the southern parts of British Columbia, Alberta, Saskatchewan, Manitoba, Quebec^[10] and Ontario.^[11] In the Dominican Republic it is found throughout the whole country.^[12][13]

Latrodectus mactans, along with Latrodectus hesperus and Latrodectus geometricus (the 'brown widow spider'), is established in the Hawaiian Islands (USA).^[14][15] One pathway of entry into Hawaii for at least one of these black widow species is imported produce^[16] (which is also considered an important potential pathway for widow spiders elsewhere).^[17]

Reproduction[edit]

When a male is mature, he spins a sperm web, deposits semen on it, and charges his palpal bulbs with the sperm. Black widow spiders reproduce sexually when the male inserts his palpal bulbs into the female's spermathecal openings. The female deposits her eggs in a globular silken container in which they remain camouflaged and guarded. A female black widow spider can produce four to nine egg sacs in one summer, each containing about 100–400 eggs. Usually, eggs incubate for twenty to thirty days. It is rare for more than a hundred to survive this process. On average, thirty will survive through the first molting, because of cannibalism, lack of food, or lack of proper shelter. It takes two to four months for black widow spiders to mature enough to breed, however full maturation typically takes six to nine months. The females can live for up to three years, while a male's lifespan is about three to four months.^[18] The female may eat the male after mating.

Prey[edit]

Black widow spiders typically prey on a variety of insects, but occasionally they do feed on woodlice, diplopods, chilopods and other arachnids. The spider's web is even strong enough to catch animals as large as mice.^[19] When the prey is entangled by the web, Latrodectus mactans quickly comes out of its retreat, wraps the prey securely in its strong web, then bites and envenoms its prey. The venom takes about ten minutes to take effect; in the meantime, the prey is held tightly by the spider. When movements of the prey cease, digestive enzymes are released into the wound. The black widow spider then carries its prey back to its retreat before feeding.^[20]

Natural enemies[edit]

There are various parasites and predators of widow spiders in North America, though apparently none of these have ever been evaluated in terms of augmentation programs for improved biocontrol. Parasites of the egg sacs include the flightless scelionid waspBaeus latrodecti,^[21] and members of the chloropid fly genus Pseudogaurax. Predators of the adult spiders include a few wasps, most notably the blue mud dauber, Chalybion californicum, and the spider waspTastiotenia festiva.^{[citation needed]} Other species including Mantis or Centipede also will occasionally and opportunistically take widows as prey, but the preceding all exhibit some significant specific preference for Latrodectus.^{[citation needed]}

Furthermore, in 2012, researchers published a paper suggesting that the black widow's close relative, the brown widow, may be competing for territory with, and ultimately displacing black widows in Southern California.^[22][23]

Toxicology[edit]

Although the reputation of these spiders is notorious and their venom does affect humans, only mature females are capable of envenomation in humans; their chelicerae—the hollow, needle-like mouthparts that inject venom—are, at approximately 1 mm., or .04 in., long enough to inject venom into humans, unlike those of the much smaller males. The actual amount injected, even by a mature female, is variable. The venom injected by the female black widow is known as alpha-latrotoxin which binds to receptors at the neuromuscular motor end plate of both sympathetic and parasympathetic nerves, resulting in increased synaptic concentration of catecholamines. The symptoms are caused by lymphatic absorption and vascular dissemination of the neurotoxin. The symptoms that result from a black widow spider bite are collectively known as latrodectism. Deaths in healthy adults from Latrodectus bites are exceedingly rare, with no deaths despite two thousand bites yearly. On the other hand, the geographical range of the widow spiders is vast. Epidemics of mostly European Widow spider bites had been recorded from 1850 to 1950, and during that time period, deaths were reported from 2/1000 to 50/1000 bites. Deaths from the Western Black Widow had been reported as 50/1000 in the 1920s. At that same time, antivenom was introduced.^[24] The LD-50 of L. mactans venom has been measured in mice as 1.39 mg/kg,^[25] and separately as 1.30 mg/kg (with a confidence interval of 1.20–2.70).^[26] In 1933, Allan Blair famously allowed himself to be bitten by the spider in order to investigate the toxicity of its venom in humans and as a means of convincing skeptics at the time who thought that the spider's venom might not be dangerous to humans.

There are a number of active components in the venom:

• A number of smaller polypeptides—toxins interacting with cation channels, which can affect the functioning of calcium, sodium, or potassium channels.
• 2,4,6-trihydroxypurine

The venom is neurotoxic.
