Lets break that down. The SR-71 was no more "designed to leak fuel" than an average car tire is 'designed to leak air'. The SR-71 was designed to continually operate at speeds over Mach 3, and where there's speed, there's friction, and friction means heat. The SR-71s hull was primarily composed of titanium which is very resistant to heat, but still expands when heated to the 400 degrees Fahrenheit it experienced when at Mach 3 speeds. Likewise, the skin would contract when the SR dropped below Mach speed. The engineers of the SR-71 designed the aircraft to be able to withstand this repetitive expansion and contraction of the skin, but it led to an issue... how the SR-71 held its fuel. The SR-71 did not have typical metal fuel tanks. Instead, it featured an innovative flexible, bladder-like fuel tank system called a 'total wet wing fuel tank system', where the fuel was directly contained by the aircraft skin its self. The gaps in the skin panels were filled with a special type of sealant made to not only hold back the fuel, but to also hold up to the repetitive expansion and contraction experienced. The problem with this repetitive expansion and contraction of the skin combined with the extreme temperatures variances experienced eventually caused the sealant to deteriorate and break down, causing leaks. Fuel sealants were applied and re-applied during maintenance intervals and when equipped with fresh seals, the SR-71s did not leak or leaked very little. The cost and time required to completely reseal an SR-71 with it's high demand for mission readiness, meant that unfortunately some leaks had to be accepted. It wasn't a 'problem' per say, but was still an issue. It was an issue such that the rate of leakage and when to replace the seals was considered and built into a maximum allowable leakage chart that listed the limits of leak rates in certain areas and when seal replacement was required. So, the SR-71 did leak fuel at times, but not 'by design' and nor was it a desired outcome. This leads to the other common myth that goes "The SR-71 leaked so much fuel that they had to fill it completely up and had to immediately refuel after takeoff". This is not true. While the amount or rate of fuel leakage varied depending on where one specific SR-71 lied on its maintenance interval timeline, on average they leaked relatively little compared to its capacity. SR-71s were not completely filled up before take-off. In fact they were actually only partially filled with fuel at takeoff for safety reasons, such as if an engine failed it would be much easier to land, as well as much easier on the brakes and tires. This is also the same reason why commercial aircraft may dump fuel before unexpectedly having to land if diverted due to weather conditions, technical problems, or emergency landings immediately after takeoff. The SR-71s unique design that allowed it to achieve its incredible speed and altitude was a detriment at low speeds and low altitude. Due to its sub optimal low-speed design, it had to use its afterburners at takeoff and during its climb to altitude, greatly increasing its already 'high' rate of fuel consumption with the partial fuel that it had at take off. There's also another reason the SR-71 had to refuel after takeoff, that's not talked about often. During Mach 3 cruise, the JP-7 fuel in its six fuel tanks heated to over 300 degrees F., with the aircraft's titanium skin reaching nearly 400 degrees F., heightening the volatility of the fuel. This led to a limitation: a maximum speed of Mach 2.6 unless an inert atmosphere was maintained inside the fuel tanks. This required the SR-71 to be equipped with nitrogen tanks that held 260 liters of liquid nitrogen so that as the SR-71 consumed fuel, the growing empty space in the fuel bladders was gradually replaced with nitrogen gas. This meant that after takeoff and achieving altitude, the SR-71 had to refuel with JP-7 so it could then pressurize its fuel tanks with nitrogen gas and go faster than Mach 2.6. So, the SR-71 had to immediately refuel after takeoff because #1, it was only partially filled with fuel at takeoff. #2 its inefficient design at low speed and low altitude made it continually use its afterburners during and after takeoff to achieve altitude. And #3 it could not go faster than Mach 2.6 without full tanks or partial tanks pressurized with nitrogen gas. The next time you hear someone say "The SR-71 was designed to leak fuel" or "It leaked so much fuel on the runway it had to immediately refuel", let them know the facts.

The app is called RedAlert and is a spyware app in disguise. RedAlert is a malicious copy of a legitimate app called 'RedAlert – Rockets Alerts'. The real RedAlert app delivers notifications of incoming rockets in Israel. Many US users have been using it to keep up to date on the frequency of rocket attacks, where hearing about them in the news takes at least a few hours after the attacks happen, if you even hear about particular ones at all. The spyware version was originally hosted on a website called "redalerts.me", but has since been taken down until whoever created app potentially shifts to a new website. On the spyware website two options were given for either iOS or Android download. After installing the app it would request permission for access to your SMS history, numbers, contacts, call history IMEI number, email accounts and others. On the surface the spyware app functions just like the legitimate Red Alert app, sending alerts like everything is normal, but it's not. After gaining access the app collects all the users info, encrypts it, then uploads it to a particular IP address. What's interesting is that the app includes measures to prevent reviewing and testing of the app for debugging. To make sure that you don't have the spyware version hold down the app icon and check the app info for the permissions its been granted. If it shows access to your phones contact information and messaging, you've been compromised.

Actually, ALL WiFi routers and Access Points have antennas. External antennas provide a farther reach for more coverage, but it depends on the antenna. Many antennas are internally mounted and not adjustable for simplicity. Internal antennas 'can' be superior at times to one without antennas, but it comes down to the use. If you get your WiFi router or Access Point issued to you by your Service Provider, you'll most likely get one without antennas. This is due to a few different reasons: #1. There's no intenna that can break because it was damaged or knocked onto the floor, causing continual problems for the ISP who have thousands of routers issued that can, and will, be broken. ISPs don't want to deal with that. #2. ISPs want to keep it simple. They don't want to deal with thousands of continuous trouble calls because of customer orienting their external antennas improperly, causing bad WiFi coverage in the home. No adjustable antennas, no problem! #3. Cost of manufacturing. Making routers and Access Points with external adjustable antennas can be expensive. When ISPs roll out thousands of WiFi routers to customers they need to purchase them at the lowest cost possible. When a customers router needs to be replaced because of a failure, it's not going to cost the Service Provider a lot of money. #4. WiFi coverage. Routers and APs without external antennas produce a slightly smaller, but spherical WiFi bubble, making coverage more consistent. For use in apartments and smaller homes this is perfect, where having antennas with gain for maximum reach is pointless. #5. The less you broadcast your homes WiFi out of your home the more security you have. Internal antennas don't blast the WiFi out through your walls and into your neighbors house like higher gain external antennas do, keeping your neighbors from trying to get into your WiFi Network. Having a smaller WiFi bubble in this case is better. Especially in denser populated areas.

Beamforming improves the signal strength, range, and reliability for devices. Beamforming is common in modern WiFi routers. Recently, many laptops, smartphones, and WiFi adapters have multiple internal antennas, enabling them to use beamforming too. But wait, WiFi adapters and router don't have moving parts? How can they "beamform"? Beamforming is accomplished using advanced signal processing techniques. WiFi adapters and routers can manipulate the phase and amplitude of the signals they emit through their internal or external antennas to intentionally interact and distort the typically uniform WiFi coverage, causing the WiFi to literally, move around. When the signals interact and combine in the air, they create constructive interference that builds up in a specific direction, making the clients connection in that direction stronger. When they interfere in just the right way and cause an increase in the connection quality, the adapter or router remembers the settings and will continue to use it, now effectively "knowing" the direction of the client or router.

CPU options, RAM, RAID cards, video cards, power consumption, everything. This specific Dell server is already equipped with dual Intel Xeon E5-2695 v2 12 core 24 thread processors running at 2.4GHz, 192GB of DDR3 memory, and is a hypervisor running VMware ESXi 8.0 on a 256GB PCIe NVMe SSD drive. The R720 does not support booting from PCIe NVMe drive, so this one is booting Clover from an internal USB thumb drive that then points to the NVMe to boot ESXi. It also has another Western Digital 1TB NVMe running on another PCIe card. The server is running a few different virtual machine operating systems such as Kali Linux 2022, Ubuntu Server 22, Windows Server 2019, Windows Server 2022, Windows 10, Windows 95 and Windows XP. On Server 2019 is it running as a Plex server for home media such as movies and television shows as well as general network storage. The front drive configuration is six Seagate 8TB HDD in software RAID 10 configuration with two additional 2TB Western Digital drives for general storage. The server fan speed has been manually reduced to lower noise output without a compromising cooling. Check out my video 'R720 IPMI Manual Fan Control Tutorial' for manually setting the fan speed. I have the CPU fans running at 30% and all of the non CPU fans lowered to 16%. Very quiet and cool! Before reducing your fans speeds make sure your server rack cooling is adequate. 0:00 Intro 0:46 Dimensions / Size 1:52 Front 4:19 Interior 5:05 Fans 8:17 Motherboard 8:55 Memory / RAM 10:27 CPUs 15:13 Network Cards 16:16 PCIe Risers / Cards 20:01 RAID Controllers 22:49 Power Supplies 23:35 Power Consumption 25:31 Rear 27:11 Outro
