probability theory – Is quantum computing a serious usable instrument for the IT industry?

Following this latest and very exciting research object I can’t find till now a usable computer in that style.

I would like to call actual quantum computing by the topic “researching of quantum elements for computing”. Till now I found only expensive and complex quantum circuits.
We don’t have usable, steerable elements to get definitive decisions by switches. We can’t find that elements in that subatomic level. We only follow mathematical rules coming from probability formulas.

How Liquid Filling Machines Benefit the Paint and Coatings Industry

How Liquid Filling Machines Benefit the Paint and Coatings Industry
Using Filling Machines to Increase Efficiency and Profitability
Liquid fillers are integral to liquid packaging lines, with automated models capable of maximizing efficiency. Without this equipment, the filling process wouldn’t be reliable enough to ensure that no product loss occurs because of inaccurate fill levels.
Technological developments that are creating more automation and computerizing many of the components in filling machines have made them more dependable than ever before, with many of the best models designed to allow for full customization and user friendliness.
One type of liquid filler that can meet the needs of the paint and coatings industry is the net weigh filling machine. Designed to handle products of low to high viscosity, net weigh fillers are ideal for filling liquids in bulk quantities, such as 5-gallon pails, with consistent weight levels for each container.
Net weigh fillers work by using independently timed valves with custom programming through the filler’s computer. They can then fill precise amounts of liquid by gravity into containers, stopping once the liquid reaches the specified weight.
These fillers can fill many different types and sizes of containers, with many of the top models capable of lasting for many years.
What is a Piston Filling Machine?
At Liquid Packaging Solutions, there are a number of different types of filling machines manufactured to handle different product viscosities, different fill sizes and other variations in packaging projects. The piston filling machine can solve many issues for products with particulates or high viscosity liquids, though it can also handle thin and medium viscosity products as well.
As product sits in the hopper, the valve, which sits between the hopper and the nozzle, will be open from the hopper to the cylinder. The piston will begin to withdraw from the cylinder, typically after an operator activates the fill by stepping on a foot switch. As the piston withdraws, product from the hopper will fill the empty cylinder. Once the piston has withdrawn to the desired point, the valve will rotate to allow product to move through the nozzle. At this point the piston push back in to the cylinder and move product through the nozzle and in to the waiting bottles or other containers. This process creates a highly accurate volumetric fill as the interior volume of the cylinder will never change, meaning the volume of product released to the bottles will never change.
The hopper sizes can vary from project to project based on the size of the containers or fills. Not all piston filling machines, and in particular, the automatic piston fillers, will use a hopper from which to pull product. Automatic lines will likely include a tank or pull from a bulk source. The cylinder and piston combination are also available in different sizes to accommodate different projects. The speed with which the piston moves can be adjusted, different piston sizes can be used to meet volume requirements and even multi-piston, automatic filling machines can be designed for use with inline packaging systems. LPS piston fillers allow the operator to adjust the length of the piston stroke, which in turn adjusts the volume of product that is pulled in to the cylider with each fill cycle. This way a single piston size can handle a range of container sizes. While multiple strokes of the piston can also be used for larger fills, at some point the efficiency of using multiple strokes will become low enough that simply changing out the piston for large containers will be the better solution.
The nozzle used on any piston filler will be chosen to meet the needs of the particular project at hand. For instance, a product with large chunks of fruit or vegetables will not work well if a narrow nozzle is used to move product in to the bottles. On the other hand, a very large nozzle will be cumbersome with a small mouthed bottle. There is virtually no limit to the type of nozzles that can be used, including custom manufactured nozzles where special projects are concerned.
Though a simple concept, the piston filler can be an ideal solution for many projects and for liquids thick and thin. Though these machines are known for handling viscous products, in the right circumstances they will handle free-flowing liquids as well. For assistance finding the best type of filling machine for your own packaging project, contact Liquid Packaging Solutions today.
Overflow fillers, gravity fillers, automatic piston filling machine and other liquid fillers all vary in the way that they move product into a bottle or container. However, the automatic versions of these machines almost always have certain features in common. These features are intended to add efficiency, consistency and reliability to the packaging equipment. Below are a few of the most common features of found on Liquid Packaging Solutions’ bottle fillers.
Heavy Duty and Portable Stainless Steel Frame
For consistent and reliable fills, the machine must be stabile throughout the process. The heavy duty stainless steel frame protects against shifting, vibrating and other movement that might effect the volume or the level of the fill, while also avoiding splashes and spills. The stainless steel material is compatible with a vast majority of products, though there are exceptions. When corrosive liquids are run on the machinery, other construction materials may be used for the frame, including HDPE. Ultimately, the material used will be that material which will better extend the useful life of the equipment.
Easy Adjustments From Height to Heads
Many packagers fill more than a single product, or at the very least fill into bottles of multiple sizes and shapes. Changing over from one product or bottle to another means stopping production on the liquid filler. These machines include simple adjustments to minimize downtime and maximize production. Fill heads can typically be moved using simple fingertip adjustment knobs, while power height comes standard on automatic equipment, allowing up and down movement with the flip of a switch. Even auxillary equipment such as power conveyors include knob adjustments or other simple components for railing and other changes. Other adjustments, such as time and delay settings, can easily be made from the operator control panel, discussed in more detail below.

Gravity filling is the simplest filling method. The uncomplicated construction and operation of gravity filling machines permits them to run with a minimum of maintenance. The supply tank (more properly called the filler bowl) is the upper, central part of the machine. Filling stems are attached to the bottom surface of the bowl at each container filling point. A vent tube extends upward into the filler bowl to a point above the liquid level. To begin the filling operation, the container is raised by the platform until it contacts the filling stem. The platform then continues to raise the container against the stem, opening the filling valve. With the filling valve open, the liquid drains into the container. The air in the container flows out trough the vent tube into the space above the liquid in the filler bowl. Although the container becomes filled, the liquid continues to flow in. The excess fluid rises in the vent tube until it reaches the same height as the liquid level in the bowl. Because the vent tube extends above the bowl liquid level, there is no overflow of liquid from the container into the bowl. If the product is foamy, the foam will rise in the vent tube above the liquid level in the bowl. If it is stable foam and will not break down, it will ultimately overflow into the bowl. For this reason, gravity fillers are not often used for foamy products. At the predetermined time after the container is filled, it is lowered from its filling position, closing the filling valve. Liquid left in the filling stem is removed from the vent tube in several ways. For most applications the liquid will fill drain into the next container. For high viscosity (thick) liquids, the vent tube is usually brought out beyond the side or top of the bowl. Here its outer end can be connected to a device that applies pressure or vacuum to the liquid in the tube to assist in the liquid removal. The total differential pressure that allows the fluid to flow is caused by the gravity head pressure in the bowl. This is usually no more than two or three feet of head, or about one psi. On this basis, it can be seen that these fillers will not permit rapid filling of viscous liquids unless they have larger diameter filling stems. To accommodate the stem, the container must also have a large neck opening; otherwise machine modifications have to be made. ElGravity 150×150 Gravity Filling Machine PrinciplesAnother type of gravity filler uses electronics. It consists of a fixed liquid reservoir or bowl with open-end filling stems. The containers are conveyed on the filling line with an intermittent motion, stopping beneath the filling stems. Inside each filling stem is a ball check connected to a long rod. A pencil shaped magnetic block is attached to the top of the rod and passes through a magnetic coil. As the container moves under the stem, it is detected by a sensing device such as a limit switch or electric eye. This device stops the conveyor, and energizes the magnetic coil. The magnetic field causes the magnetic blocks to lift, raising the rod and the ball check from its seat inside the stem. The rate and amount of fill is controlled by the size of the stem orifice and time delay relay connected to the magnetic coil. Because a direct insertion filling tube is not used on this type of gravity filler the filling stem orifice must be smaller than the inside diameter of the container being filled. On small size containers a more positive means for positioning the bottle beneath the filling stem is used. Fill Height Control In addition to controlling fluid flow, control of the filling height is also important. In general filling machines that elevate the container control the fill height from the bottom of the bottle to the liquid level. The rise of the container is positive, and variations in overall container height are compensated for by greater or lesser seal compression. On rising container machines, a compression spring is often built into the tray elevating mechanism. In this case, container height variations are compensated for by the spring, and the fill height is then controlled from the top of the bottle to the liquid level. Controlling the fluid level from the top can be important if the bottle to be filled has square shoulders, because even a slight under fill is noticeable. In rising stem fillers, variation in container height is taken up by the stem itself. It is usually lowered by gravity or light spring pressure, so the fill height is controlled from the top of the bottle to the liquid level. If the product contains a volatile liquid, such as alcohol, control of the fill height is especially important. In this instance, excessive headspace could allow dangerous vapors to form and the bottle would possibly burst if it were stored in a hot warehouse. Therefore, controlling the fill height is an important function of the filling machine. Normally, a fill height tolerance of 1/32″ is acceptable. Container Control There are several devices used to control the containers coming into the filling area. Included are star wheels, worm or screw sorters, and lug chains. They can be used independently or in combination, depending on the type of container, the filling machine, and the product being placed in the container. The majority of all liquid filling machines operate as continuous filling devices. In most applications the machine has a large rotating filling head, which must be constantly supplied with containers. This is accomplished by a continuously running flat top chain conveyor feeding a star wheel or lead screw device. From here the containers are fed into the filling section. Star wheels when used alone separate the containers so they will be properly located beneath the filling stem. They can be made to handle a variety of container designs, although in some cases, the containers may have to be guided into the star wheel to ensure proper separation. Worm sorters are often used to guide containers into a star wheel. They can be short in length and only located near the machine in feed, or they may be full length of the machine’s main conveyor. The amount of container control determines the worm length. In most cases, worm sorters are very much like a wood screw; starting out small in diameter and then increasing to full diameter. A continuous pocket is formed at the root between the raised portion or crest of the thread. This pocket carries the container into its position on the filling machine by a rotating action. Because each container is different in design, worm sorters are usually made for individual applications and are not an “off-the-shelf” item. Lugged chains are normally used with inclined conveyors and semiautomatic filling machines. These machines can be either continuous or intermittent motion devices. The chain lugs are spaced to match the filling nozzles or stems. For example, if the filling stems are on four-inch centers. The chain is adjustable at the drive sprocket for timing purpose only. Position adjustments are usually made by moving the filling heads. Whatever method is used for container control, it is an important part of proper machine operation.

user names – What are the industry recommendations on usernames?

Most of the user names are based on the actual name. 1-3 letters of name + surname or similar combinations. Admins are no exceptions.

For the administrative side, many use the ABC format:

a-names are the main admins of the company with the highest access

b-names are the secondary admins with lower access (low-med support) or backup/recovery admin accounts

c-names are the contractors with very limited access (like L1 contractor support)

Some companies prefer for the simplification of things to use the employee ID which is usually a 3 or more digits number. It simplifies many administrative tasks, not only IT-related.

Randomization of a-names is a time killer, it’s not recommended. And it does not improve security much; any user can see that name if it ever accessed its device. You can improve your security by using well managed account access, with transparent access boards and on-spot generated and allocated passwords for highest levels of access.

A general recommendation is of course not to use the same account for daily work and administrative tasks. That means that you will have your standard account (name or number ) and a different one with privileges (a-name or a-number ).

As a standardization, there is no universal rule; each company will decide on a template for that and go with it. Then it rarely ever changes, except if they are brought by another bigger company that comes with its own rules.

Industry Roundtable: The Chia-Driven Hard Drive Shortage

Every month, LowEndBox puts a question in front of hosting industry leaders and LEB community providers, who are invited to comment and offer their perspective.  Our goal is to stimulate discussion around important issues in the industry, inform our readership, and help other providers so the community as a whole benefits.  If you have a question you’d like to put to the round table, please submit it to us!

This month’s question:

What effect has the Chia Crypto-driven hard drive shortage had on your business? If you sell dedicated servers, do you have concerns that users are going to burn out gear? Have you experienced difficulties replacing gear due to price increases? Or has the Chia phenomenon been a boon to sales?


Stacey Talieres, Director of Marketing, InterServer

The articles from 2008 did in fact predict the depletion of IPv4 allocations correctly. All regions such as APNIC, ARIN, AfriNIC and RIPE were exhausted by around 2011. Currently there are some hosting companies definitely sitting pretty on large amount of allocations. Other hosts followed the rules and requested only the appropriate amount needed. As of right now (April 2021) the cost per IP address is $28. As allocations are further depleted and hosts are forced to purchase IPv4 on the open market it will inevitably lead to the cost of a VPS to increase. On the flip side its quite possibly that the cost of a VPS with IPv6 ONLY could go down to offset the increase associated with IPv4. InterServer is considering offering a discount to customers that opt out of ipv4 when ordering a VPS.




VirMach has been acquiring hardware at a rapid rate as we move toward colocation with Ryzen CPUs & NVMe SSDs as well as expanding HDD storage nodes to more locations, so we have been monitoring nearly all hardware prices very closely.

Out of everything that has transpired since lockdowns began, I feel like the Chia situation has been widely exaggerated and it is most likely dead-last in terms of significant industry impact (including all other storage-based cryptocurrencies.) At most, it resulted in a very temporary spike in price or a slight delay in obtaining a specific hard drive model and capacity. In fact, a big part of this may have been people panic-buying hard drives as sensationalized news articles spread. It looks like as of today, prices have already returned to normal levels in most markets.

In reality it just meant some minor inconvenience in acquiring hard drives with a slight price impact and maybe having to consider other models.

In terms of impact on hardware durability, Chia will wreak havoc on the solid state drives utilized to initially “plot” or otherwise perform the initial extensive disk operations, and will leave hard drives relatively unscathed. As for difficulties in replacing gear and concern in price increases, we are more worried about the blatant decrease in quality of other components, such as lower quality controllers and NAND in NVMe SSDs, combined with price hikes instead of the usual reductions. Even RAM ends up being affected since reputable companies have shifted their focus to more profitable market segments and essentially discontinued some production.

Perhaps if Chia has any lasting impact, it will be in the form of adding fuel to the fire in SSD pricing as some are damaged more quickly and ultimately taken out of the supply pool but that’s more or less baked into the overall impact of the less durable hardware previously mentioned.

The entire concept relies on “proof of space and time” which means a lot of space, and a lot of time, two things that will result in an expensive bill to the customer attempting to earn this type of cryptocurrency. Last I checked, a customer would have to rent at least about 20TB HDD and a 2TB NVMe for an entire year at about $2/TB/month to break even.

We would welcome anyone purchasing our cloud storage services for Chia farming as long as they understand how it all works, which means they would most likely have to contact our sales team to add a dedicated NVMe SSD for plotting.


Dustin Cisneros, CEO of RackNerd

I’ve always been a firm believer that there’s plenty of IPv4 space available in the market place (despite what the media/news portrays), and to this day, we have access to large amounts of IPv4 addresses like never before. While it is true that certain RIR’s have stopped issuing new allocations, there is also an abundance of aftermarket activity, as well as existing ISP’s who have IPv4 allocations that are unused. We leverage our upstream’s, and also cater to customers who are after diversity, and successfully do so. We also leverage partnerships and lease IPv4 through third parties. Our rates are aggressive on IPv4 as a result of our large scale and commitments that we’re able to take on, and as such, we’re able to extend these savings down to our customers.

Worldwide adoption for IPv6 will continue to be slow. Providers often times recognize this too, and help stimulate the IP economy by leasing out their excess IPv4 space, and/or providing their ranges at aggressive rates.

For those who are looking for dedicated servers with large IPv4 allocations, i.e. dedicated servers with /24, dedicated servers with 16x /28, or even dedicated servers with 32x /29 IPv4 allocations, RackNerd can accommodate both your diversity and IPv4 requirements at affordable prices! Take a look at RackNerd’s large IPv4 allocation dedicated servers.

Thank you to all of our providers for participating this month!

If you have a question you’d like to put to the round table, please submit it to us!
