A Crippled Weak Network

Good afternoon my fellow party members,

I don’t know if everyone has been watching the news recently, but there has been a rash of large companies that have been brought to their knees due to large scale network outages. Some of the most noticeable is the recent South West and Delta Airlines outages. South West’s computers where down for almost three days, all because of a failed router. And Delta was down for almost an entire day due to a failed power switch, but in Deltas case, even once the power switch was replaced, it took them almost the entire day to restart their computer systems. And the fact that it effected their global business as a whole, shows that they haven’t prepared their systems for a major failure. From what reports say, Delta Airlines’ computer system is based off of a legacy system that is so old, It most likely loads its data off of original Floppy Disks, and tape cassettes. (I’m thinking more in the tune of the computer system from Captain America Winter soldier) But what is the most shocking to see, is the fact that their entire company has that one critical failure point. Their network is a hub and spoke network, that can’t function without the central hub. There is no interconnects between the spokes, and there is no backup datacenter that can take over the system load in case the main hub goes down.

For any company to make a data system that can be so unreliable in the event of a failure, must not really be concerned about their company’s ability to operate efficiently and smoothly in the event of failures. In the matter of failures that could plague a data operation, there are many things that could take a datacenter down. anything from power failures to fiber cuts, if it affects the connection to your datacenter connecting to the outer spokes of the business, it will effect the bottom line. There are however ways around this. To prevent your company from feeling the effects of a datacenter failure, a full mesh network is recommended. Mainly by using multiple slightly smaller data centers. By having multiple datacenters that replicate data across the network, you can ensure that the spokes of your network will always have a place to connect to.

So what’s better? Spend the money now to make the profits later? Or save the money now to loose money later?

McDonalds Gilroy Garlic Fries? Y/N?

OK, so the new Gilroy Garlic Fries from McDonald’s?

I finally got to try some, and I am not impressed. The garlic and Parmesan mixture tastes wonderful, don’t get me wrong, but put on soggy fries, it just doesn’t mix. I’m struggling eating these and typing this at the same time. I for some reason was hoping for something much much more. I believe though that the McDonald French Fri is just not suited for the task of holding a buttery garlic Parmesan and parsley sauce without just completely breaking down. And once they get cold, they just become this cold soggy mass. I haven’t yet tried them completely chilled, as i figure the butter would make them completely inedible. or maybe it isn’t even butter they use, but rather that liquid margarine? I will never know as I no longer work in a McDonald’s my self. All of this is giving me an upset stomach.

So McDonalds New Gilroy Garlic Fries? Yes or No???    I’ll say no.

How in the world is this site here???

Hello again!

Just some random stuff this time,

First, if you were wondering and you can’t tell, this sight is a WordPress site. I chose a WordPress site, because of its ease of operation, and the fact that I could get a ready to run image up and running to run the site in a matter of an hour.

Second, WordPress is running off of a Turnkey Linux core. Part of the reason I could get it up and running so quickly!

Lastly, for hosting, I decided to go with a hosting solution that I could trust. A hosting provider that if there was any down time, I would know exactly what is wrong, and would know exactly how long it will take to repair the issues. And that hosting provider? None other than myself!

I figured if anyone was wondering, this is how everything goes together. I figure why should I pay for hosting, when I can do it all myself!

And BOOM Goes the… Smartphone?

Hello all!

First of all, sorry for the delay in posting. As usual I travel on the weekends to remote locations that don’t have any kind of connections what so ever. I did take some photos, those of which, I will upload later on once I get them off of my camera and sorted out. But this weekend, I left my Samsung Galaxy Note 5 out in the sun while it was in its case, and when I retrieved it (off the dashboard of the boat), I checked the internal temperatures using an app called CPU-Z. One thing I found interesting, was that the Snapdragon Octacore processor was still able to perform reasonably well even though its temperatures had peaked past one hundred seventy five degrees Fahrenheit. Parts of the battery where at one hundred and fifty degrees, and the overall core of the battery was just past one hundred and thirty. However, despite the extreme temperatures, the phone still played music without skipping a beat. But those temps got me to thinking about what powers the phone and how delicate that one component actually is.

The lithium ion batteries that power our devices, if they are anything similar to the batteries that power RC cars and drones, seem to not like sharp impacts or extreme heat. And when you charge these batteries, you are told to put them into bags that are made out of a puncture resistant, fire resistant materiel, in case the battery decides to “do other things.” And on that point, I have been seeing more and more reports about phones “exploding” in the pockets of their users. As just a few days ago, an Australian man’s iPhone exploded after he fell on top of his iPhone and received third degree burns because of the resulting fire.

So what are the phone manufacturers not telling us about these phones? Is your phone a potential ticking time bomb? Will it randomly explode the next time you make a phone call? Probably not. As for what are the manufacturers not telling us about our phones? They have nothing else they should need to say. As in every box that a new phone comes in, there is an instruction manual that warns about the potential dangers of lithium ion batteries. But those warnings mainly focus on “Do not puncture” or “Do not put in fire” or “Do not expose to extreme heat.”

In the case of the Australian man’s exploding phone, the reason for the explosion was very simple. When he fell on his iPhone that was in his back pocket, the battery suffered from some sort of trauma, and had the internal structure of the battery damaged. And depending on the previous damage and the age of the battery, the forces that where acting upon the phone during the accident, could have been just enough to send the battery over the edge.

So what is causing these lithium batteries to explode? It’s a process called thermal runaway. When a lithium cell is damaged and causes a short circuit, the cell will start producing more heat than what can be expelled. As more of the internals of the battery start to melt down, the more heat that is produced. Finally, enough heat is being produced, the electrolyte inside will combust, causing a fire. The “exploding part is caused by the pressures built up inside of the battery will cause the surrounding packaging to pop, thus releasing the burning electrolyte.

Now there are hundreds of millions or more lithium batteries being produced every year, and billions of lithium batteries being used currently. And the number of reported cases of lithium batteries exploding are still surprisingly low. However, a number of cases involve E-cigarettes, which work by creating a short circuit and heating a coil that vaporizes the liquid in the chamber. Mind you the key word here is short circuit, and what happens when a lithium battery short circuits? It goes poof.

But exploding batteries can also be caused by improperly charging them at the wrong current and voltage, physical damage to the cell, and extreme heat.

But all in all, there is no reason to panic, your phone is not going to randomly explode. As long as you don’t leave your phone in the sun, or smash it. Plus, try to refrain from dollar store chargers, as they usually are missing all of the safety circuits that are present in the stock chargers. And the chances your phone are going to explode? Probably won’t happen to you ever.
