New Database Management Tool

Lucky to find a Flyway alternative that has all the features I require at a much lower price. Rumba supports popular plain-SQL migration scripts, versioning, and database schema changes tracking at full scale.

Migrations of database schemas are an unavoidable part of any database-driven software project. You may need to update your database structure as your project grows to accommodate new features or address faults. When it comes to designing and delivering applications, schema migrations are critical. You can ensure that your database is always consistent and compatible with the current source code by using the right tool.

I’m not interested in any of the particular database engines, programming languages, or framework support. I already have my preferred database and have discovered that such a tool cannot rely on project code in any way. Framework integration, such as the ability to change database schema at application startup, will train programmers to do terrible things.

Declarative schema definition would be a great addition to such a database management tool. It would allow to easily and faster define the data structure in some way. This would be especially beneficial for prototyping when the database scheme is rapidly changed.

The helper tool must provide a way to quickly generate SQL scripts for database changes. It would be nice if it could also help format the resulting script for readability, but that is not a requirement. Being able to quickly generate the script without having to worry about the syntax is key. The next feature I would want is the ability to compare two versions of a database.

Less price, lower the risks

When beginning a project, keep in mind that there will always be risks and costs. While it is critical to consider the risks and costs of a project, it is also critical to be realistic about the potential return on investment. In some circumstances, the investment may be too large in comparison to the prospective return. In these instances, it may be wise to look for another project to invest in.

This type of software may be fairly expensive; the licensing fee of the most marketed products starts at three thousand dollars in yearly subscription, which will delay my prospective investment return.

A perfect tool should be self-contained and free of third-party dependencies. This is significant because it guarantees that the tool will always be available and reliable, regardless of the setting or context in which it is utilized. It also removes the need to locate and install any other software or libraries, which can be a time-consuming and tedious procedure.

Flyway drawbacks

Flyway requires Java installed and offers features I’ll never ever use. Some of its features are doubtful, some other features are not compatible with my development. I also don’t need any exotic database support. I always stay with PostgreSQL.

Science Finds Exactly the Right Amount of Coffee You Should Drink a Day

I can resist everything except temptation.
— Oscar Wilde.

Four cups of strong coffee a day might be the recipe for a healthy heart, especially for older adults.

A team of German researchers, led by the molecular biologists, thinks it has discovered clues about how coffee works after it leave a coffee grinder. Its caffeine-fueled magic on our heart health and how much caffeine we should drink each day to see the best benefits.

By studying caffeinated lab mice and dosing human tissues with caffeine, the researchers discovered how a jolt of the stimulant could improve the way cells inside our blood vessels work. By making certain proteins inside older adult cells perform more like young and nimble ones.

“When you drink four to five cups of espresso, that seems to improve the function of the powerhouses of our cells, and therefore seems to be protective.”

Scientists have for years noticed that people who drink coffee seem to be less likely to die from all sorts of causes, including heart disease, stroke, or diabetes.

Coffee is also associated with a whole host of other health benefits, including a lower risk of liver disease (cirrhosis), a lower risk of developing certain kinds of cancer, lower rates of dementia and Alzheimer’s, and a reduced risk of depression. It’s also great for your heart.

If you don’t like the taste, green tea has similar levels of caffeine and could also be an effective way to boost heart health.

It’s important not to overdo it with the new recommendation, as too much coffee can quicken your heartbeat and cause other health problems. But drinking up to six cups a day should be OK.

One caveat: The study wasn’t done in humans – only in human tissues and lab mice. What works in a hyper-controlled environment of mice, dosed with very specific amounts of caffeine, may not be the same as what happens when you drink a cup of joe at home.

Burr Coffee Grinder Types

Basically, roasted coffee beans need grinding or milling to be able to convert them into fine powdery form before brewing them. Grinding or milling is completed to facilitate the brewing process and it’s also an important aspect as grinders strongly impact the quality of brewing because it needs to be matched utilizing the brewing method used. The best coffee will soon be produce with both factors working in perfect harmony.

These days, there are 2 kinds of coffee grinder plus they are either burr grinder or blade grinder. With moving grinding wheel and stationary surface, the burr coffee grinder crushes the beans instead of chopping them like a standard blade coffee grinder would do.

The burr is put in a particular way which regulate the ground size, thus making the grinding process more reliable than merely using a blade coffee grinder. With burr coffee grinder, even grounds are produced and hence the coffee flavor is more consistent.

In the burr grinder category, you will find two different kinds, namely the Wheel Burr Grinder and also the Conical Burr Grinder. They differ particularly in regards to price and how it works. The wheel burr grinder can spin extremely fast but it produce a much noisier sound. In addition, the high speed rotation grinder will provide a messier coffee bean as well.

Nevertheless, it is cheaper in comparison with the conical burr grinder. The conical burr spins slower and so it produce sound much more quiet than wheel burr, less messy and most likely not to clog. It can be used for either oily or flavored coffee beans helping to make this sort of burr higher priced.

Burrs also offer a range of sizes when it comes to grounds, from powdery or coarse grounds and these burrs work differently in several types of coffee makers, such as the espresso machines, French presses and on occasion even the conventional coffee makers. Aided by the accessibility to these burr grinders, one can possess the freshest cup of coffee whenever you can and also saves a person’s money and time from buying it from the coffee shop.

France’s Trial ‘Solar Road’ Has Been Unsuccessful

This project is a great sample of spending budget on ridiculous things. When almost every engineer who has a piece of paper and a pencil expected the ineffectiveness of Solar Road, the eurocrats continued to waste taxpayer money zealously.

We have commercialized installments of solar cells world wide, and we understand that they are still expensive compared to other energy sources. The solar arrays are aligned with the Sun to obtain more efficiency. They are usually washed regularly, get a lot of repairs and maintenance, and nobody is going to damage any of them with several tons of mass. This is why the solar roadways will never be so effective as solar powered energy stations. The solar highway may not be aligned with the Sun, and it usually will be shadowed by vehicles! It is so damn foreseeable!

Second ridiculous idea is to use tech in attempts to make the solar roadway enabled to withstand the damage. The highway engineering companies spent hundreds of years in cost efficiency optimization. Changing the highway coat with costly solar boards will ruin the ROI for each of them: the highway and the solar energy project.

I highly doubt that such solar roads are going to be a part of the nearest future. No matter the amount of money is going to be invested in research and the number of coffees mugs the technical engineers will drink.

About Me

Many thanks for exploring my blog. My name is Gordey Pokrovsky, and I work as a software developer for a marine transportation company. This website exists solely as a channel to study from other people and share my experience.

I do not blogged previously and bit excited to start my journey. I have no worry to start another tech project at my work. But I am really new to blogging.
