Everyone should avoid bug bites. For a bug repellent that’s safe and effective—and that won’t stink or leave a puddle of oil on your skin—skip the DEET and get a picaridin formula, like Sawyer Products Premium Insect Repellent with 20 percent picaridin. It’s the best bottle of bug spray we found after testing 17 repellents and talking to everyone—from the EPA to the American Mosquito Control Association. One fact to establish up front: There’s no evidence that mosquitoes can transmit the coronavirus—but the diseases that biting insects do carry ain’t no picnic either.

Trailer FrenzyA special place to find the newest trailers for movies and TV shows you’re craving.
When you think of Snake Eyes you think of the mask, the swords, the unstoppable ferocity. But how did the popular G.I. Joe character become that guy we’ve seen in comics, cartoons, and toy aisles for decades? We’re about to find out, in a whole new way. The first trailer for Snake Eyes: G.I. Joe Origins is finally here.
The film stars Henry Golding as the titular character, seen here years before he meets up with the Joe crew. Directed by Robert Schwentke, Snake Eyes follows the character as he becomes indoctrinated into the Arashikage clan, learning the ways of the ninja alongside Storm Shadow (Andrew Koji), the group’s heir apparent, and eventually popular Joecharacters like The Baroness (Úrsula Corberó), and Scarlett (Samara Weaving) show up too. But this is the Snake Eyes show and, in the first trailer, you get just a taste of what the film has in store.
The film is meant to kick off a whole new G.I. Joe franchise and if you’re curious to know more, check back soon—io9 spoke to Henry Golding all about it. Snake Eyes: G.I. Joe Origins hits theaters on July 23.

Tell me why the AP was in a building that Hamas was using to store weapons.
Oh yeah, because the AP were acting as human shields for Hamas, assuming that Israel wouldn’t strike their offices while Hamas hid rockets in the basement.
After providing advance warning to civilians & time to evacuate, IDF fighter jets struck a multi-story building containing Hamas military intelligence assets.
The building contained civilian media offices, which Hamas hides behind and deliberately uses as human shields. pic.twitter.com/zeDjEquePD

U.S.A. –-(AmmoLand.com)- One of the best things about some of the optics advancements in recent years has been the ability to incorporate them into all sorts of firearms, including pistols. This proves extremely beneficial for acquiring a target with as little effort as possible and takes the guesswork out of aiming. For a new and inexperienced marksman, this gives immediate results with little effort; that is, if it’s dialed in correctly.
Holosun offers a broad range of reflex sights that will work on properly equipped pistols. The 407, 507, 508 and 509 series come with all sorts of options. Mounting interface, reticle choice and color are the most obvious choices that need to be made. While these optics series are going to be different sizes, they are adjusted in remarkably similar ways.
When first using a reflex optic – let’s use the 508 series, for example – check to see if there are any specific items or tools necessary for adjustments. While the 508 series need a small flathead screwdriver, other brands may require custom tools and measurement systems. This is one significant benefit and testament to the consistency of Holosun products.
The Process:
Here’s a few basics before we begin on the overall process. Every optic will have a north-south knob for adjustment and an east-west knob for adjustment. Depending on where you aim and the location of the impacts, any changes to point-of-impact would be made using these knobs. Holosun includes a small tool that can be used for making these adjustments. Every time the knob is twisted, there will be a small ‘click’ sound. Each click is equivalent to a 1 MOA adjustment which may be unnecessary to know depending on your method for finding zero.
#1: With standard sight co-witness:
With some pistol optic installation, the ability to use the standard sights may still be possible. One method of zeroing a reflex optic is to line the dot from the optic over – or directly on – where the point of aim would normally be on the standard sights. There is some personal preference when it comes to co-witnessing. The next step would be as easy as heading to the range. From there, if the projectile is traveling too far in any direction, move the reticle an appropriate amount using the built-in knobs.
#2: Without co-witness:
A bit more complicated, this method can also be used even when co-witnessing. While you can eyeball it and waste ammunition in the process, a 10-yard zero target makes the process move without a hitch.
Pistol zero targets will most likely have an MOA measurement built-in. They are reliable if a target is set up at the proper distance. With an optic mounted and the target set up at ten yards, fire a group of 5 shots. From the shot group, find the center and estimate the MOA adjustments necessary to reach the bullseye. Using the dials on the side of the optic, adjust accordingly. Remember, Holosun pistol optic adjustment values are 1 MOA per click, so a 3 MOA adjustment would be three clicks.
Final Steps:
Following any adjustments, it’s recommended to do the same target process 3-5 times. After each group, continue making slight adjustments if necessary. This will do several things.
First, it will work out the user’s cobwebs and any flinching that might have happened during the first group shots.
Second, it will allow the settling in of any irregularities with the pistol, such as lack of lubrication or magazine difficulties.
Third, it will also test the consistency of the ammunition itself. Ammunition is one of the largest uncontrollable variables when finding zero and the accuracy of any firearm.
Conclusion:
So, there you have it! Two methods of zeroing your pistol-mounted optic. Promptly, find some inexpensive ammunition and get out to the range. The only thing standing in the way of an accurate pistol is you… and ammunition prices…

"An EV motor has been developed that uses no magnets, thus lessening the United States’ reliance on Chinese magnets (which make up 97% of the world’s supply)," writes Slashdot reader nickwinlund77, adding: "I wonder what the motor’s performance is like on high grade roads?" New Atlas reports: German company Mahle has just announced a new electric motor that sounds like it solves a lot of problems in a very tidy manner. The new Mahle design uses no magnets, instead using powered coils in its rotor. Unlike previous efforts, it transfers power to the spinning rotor using contactless induction — so there are basically no wear surfaces. This should make it extremely durable — not that electric motors have a reputation for needing much maintenance. The lack of expensive metals should make it cheaper to manufacture than typical permanent-magnet motors. Mahle says the ability to tune and change the parameters of the rotor’s magnetism instead of being stuck with what a permanent magnet offers has allowed its engineers to achieve efficiencies above 95 percent right through the range of operating speeds — "a level that has only been achieved by Formula E racing cars." It’s also particularly efficient at high speeds, so it could help squeeze a few extra miles out of a battery in normal use. The company says it’ll scale nicely from sizes relevant to compact cars up to commercial vehicles.
"Our magnet-free motor can certainly be described as a breakthrough, because it provides several advantages that have not yet been combined in a product of this type," says Dr. Martin Berger, Mahle’s VP of Corporate Research and Advanced Engineering. "As a result, we can offer our customers a product with outstanding efficiency at a comparatively low cost." Mass production is about two and a half years away, according to IEEE Spectrum, and Mahle has not yet nominated which auto manufacturers it’s dealing with, but test samples are already starting to circulate.
Problem Formulation: How to insert at the first position of a list in Python?
Solution:
Use the list.insert(0, x) element to insert the element x at the first position 0 in the list. All elements j>0 will be moved by one index position to the right.
You create the list [5, 1, 3, 8, 7, 9, 2] and store it in the variable lst. Now, you insert the new element 42 to the first position in the list with index 0. Note that Python uses zero-based indexing so the first position has index 0. The resulting list has 8 elements instead of only 7. The new element 42 is at the head of the list. All remaining elements are shifted by one position to the right.
To dive deeper into the very important list.insert() method, I’d recommend you watch my full explainer video here:
Note that some people recommend to insert an element at the first position of a list like so:
While the output looks the same, this doesn’t actually solve the problem because the list concatenation operator list_1 + list_2 creates a new list with the elements of two existing lists. The original lists remain unchanged. Only by assigning it to the variable lst, you overwrite it. However, if another variable would point to the old list, this option based on list concatenation wouldn’t work because the old list remains unchanged.
In this example, you create two lists lst_1 and lst_2 both referring to the same list object in memory. You try to insert the new element at the beginning of the list using the problematic method. And you obtain a clash—both lists refer to different objects in memory!
>>> lst_2
['new', 1, 2, 3]
>>> lst_1
[1, 2, 3]
Thus, the list.insert(0, 'new') method is superior to list concatenation to insert an element at a given position in the list.
