Suggested December 2023 Mysql Not Going Closed Source?
MySQL is one of the most popular databases in use today, a popularity that has been driven by the open source community. Some in the community, however, are taking issue with exactly how open MySQL actually is as fears about the future of the open source database grow.
At stake and at issue are the $1 billion dollars Sun has invested in MySQL. As community members question Sun’s intentions, MySQL defends its turf.
This week Sun’s MySQL division preannounced the release of MySQL 5.1, which is expected to be available in June. The actual release is months behind schedule and follows the last major MySQL release, MySQL 5.0, by two and half years.
MySQL also announced some new features for MySQL 6, currently in Alpha development.
Among the MySQL 6 features are online backup to the database. Some of the online backup features, however, may not end up in the community version of MySQL but instead will only appear in the commercial MySQL Enterprise Edition. (MySQL offers a free community edition and a paid subscription edition.)
It’s a move that has prompted some fierce criticism of MySQL on blogs and on open source site chúng tôi
The firestorm began in earnest with a blog posting from MySQL consultant Jeremy Cole, who alleged that by offering features only in MySQL Enterprise, MySQL is changing its development model.
“The size of the user base for MySQL Enterprise is much smaller than for MySQL Community,” Cole wrote. “That means these critical features will be tested by only a few of their customers. So, in effect, they will be giving their paying customers real, true, untested code.”
Cole’s sentiments were echoed by others, including MySQL consultant Vadim Tkachenko, who also questioned MySQL’s openness.
“A Year ago I remember MySQL Proxy was not available for wide usage, only for enterprise customers. Fortunately, it was changed during last year,” Tkachneko blogged.
“Now we see that new features will be available only for Enterprise customers. Why does Sun decide to develop new software under Open Source license, but MySQL decides to take away features developed for next version.”
In a series of posts on Slashdot.orgm, Marten Mickos previously CEO of MySQL, now senior vice president at Sun, defended and clarified MySQL’s open source commitment and positioning.
MySQL spokesperson Steve Curry confirmed to chúng tôi that the postings made on Slashdot were in fact made by Marten Mickos.
“Having production add-ons that we provide only to paying customers currently seems to be a useful model,” Mickos wrote. “Our partners and customers think it is great. Many users think it is great. But not all do (as evident from this thread on). I would hope we could please all, but I am afraid we cannot.”
Mickos also strongly defended MySQL technology release schedule and closed technology components as not having been influenced by Sun. The former MySQL CEO noted that the decisions relating to the MySQL 5.1 and 6.0 releases were developed by MySQL months before being acquired by Sun.
In fact, Mickos noted that Sun actually asked him if the company should open source all of the backup components.
“I will have such a discussion with my colleagues at Sun in the coming months,” Mickos wrote.
While inflamed passions are nothing new in the open source community, neither is MySQL making certain components only available to paying customers. 451 Group Analyst Matthew Aslett noted in his analysis on the topic that MySQL has already announced database design tool MySQL Workbench would have components that are not available as open source.
“Before that the company introduced Network Monitoring and Advisory Services with the enterprise version in October 2006,” Aslett wrote. “Additionally, MySQL removed the Enterprise tarballs from its community FTP site in August 2007.”

How Does Mysql Datetime Works With Example
Introduction to MySQL Datetime
The following article provides an outline for MySQL Datetime. Suppose we want to store a value of date that contains both date and time in it. Then we use the Datetime format. Datetime stores the data in year, month, date, hour, minutes, and seconds. The Datetime uses 5 bytes for storage. We can also store the fraction, but holding the fraction would increase the storage. Considering precision and wanting to keep the precision fraction(0) takes 0 storage bytes. Suppose fraction (1, 2) takes 1 byte. Fraction (3,4) takes 2 bytes, and a fraction (5, 6) takes 3 bytes of storage. A total of 3 bytes would need extra for the storage of fractions.

How does MySQL Datetime work?Now let us create a table with a column data type as datetime and get the result.
Code:
CREATE TABLE TEST_DATETIME1 ( ORDER_ID VARCHAR(10), ORDER_DATE DATETIME );Let us insert the data into the table:
INSERT INTO TEST_DATETIME1 VALUES ('O1','2023-01-01 12:00:00'); INSERT INTO TEST_DATETIME1 VALUES ('O2','2023-02-02 12:00:00'); INSERT INTO TEST_DATETIME1 VALUES ('O3','2023-03-03 12:00:00'); INSERT INTO TEST_DATETIME1 VALUES ('O4','2023-04-04 12:00:00'); INSERT INTO TEST_DATETIME1 VALUES ('O5','2023-05-05 12:00:00'); INSERT INTO TEST_DATETIME1 VALUES ('O6','2023-06-06 12:00:00'); INSERT INTO TEST_DATETIME1 VALUES ('O7','2023-07-07 12:00:00'); INSERT INTO TEST_DATETIME1 VALUES ('O8','2023-08-08 12:00:00'); INSERT INTO TEST_DATETIME1 VALUES ('O9','2023-09-09 12:00:00'); INSERT INTO TEST_DATETIME1 VALUES ('O10','2023-10-10 12:00:00'); select * from test_datetime1;Output:
Here we check the data for the “order_date.” We could see that the storage taken for the column is 7 bytes as it saves the precision fraction of (3, 4).
If we see the value of “ Date_time “ value:
2023-01-01 12:00.00.000
Given below is the format of the above data:
yyyy-mm-ddhh:mm:ss:ff
YYYY: Is the year – 2023
MM: Is month – 01
DD: Is Date -01
HH: Hour – 12
MM: Month – 00
SS: Second – 00
FF: Fraction seconds – 000
As per the above example:
‘2023-01-01 12:00.00.000’
Code:
CREATE TABLE TEST_DT ( SERIAL_NUMBER INT, DATE_TIME DATETIME );Now let us insert into the table with the current date:
INSERT INTO TEST_DT VALUES (1,'2023-01-01 09:22:08:123'); INSERT INTO TEST_DT VALUES (2,'2023-01-02 10:22:08:123'); INSERT INTO TEST_DT VALUES (3,'2023-01-03 11:22:08:123'); INSERT INTO TEST_DT VALUES (4,'2023-01-04 12:22:08:123'); INSERT INTO TEST_DT VALUES (5,'2023-01-05 13:22:08:123'); INSERT INTO TEST_DT VALUES (6,'2023-01-06 14:22:08:123'); INSERT INTO TEST_DT VALUES (7,'2023-01-07 15:22:08:123'); INSERT INTO TEST_DT VALUES (8,'2023-01-08 16:22:08:123'); INSERT INTO TEST_DT VALUES (9,'2023-01-09 17:22:08:123'); INSERT INTO TEST_DT VALUES (10,'2023-01-10 18:22:08:123'); INSERT INTO TEST_DT VALUES (11,'2023-01-11 19:22:08:123'); INSERT INTO TEST_DT VALUES (12,'2023-01-12 20:22:08:123'); select * from TEST_DTHere we check the data for the “order_date”. We could see that the storage taken for the column is 7 bytes as it saves the precision fraction of (3,4).
If we see the value of “ Date_time “ value:
2023-01-01 09:22.08.123
Given below is the format of the above data:
yyyy-mm-ddhh:mm:ss:ff
YYYY: Is the year – 2023
MM: Is month – 01
DD: Is Date – 01
HH: Hour – 09
MM: Month – 22
SS: Second – 08
FF: fraction seconds -123
Output:
Example of MySQL DatetimeGiven below is the example mentioned:
CREATE TABLE TEST_DT1 ( SERIAL_NUMBER INT, DATE_TIME DATETIME );Now let us insert into the table with the current date:
INSERT INTO TEST_DT1 VALUES (11,'2023-01-11 09:22:08:123'); INSERT INTO TEST_DT1 VALUES (22,'2023-01-12 10:22:08:123'); INSERT INTO TEST_DT1 VALUES (33,'2023-01-13 11:22:08:123'); INSERT INTO TEST_DT1 VALUES (44,'2023-01-14 12:22:08:123'); INSERT INTO TEST_DT1 VALUES (55,'2023-01-15 13:22:08:123'); INSERT INTO TEST_DT1 VALUES (66,'2023-01-16 14:22:08:123'); INSERT INTO TEST_DT1 VALUES (77,'2023-01-17 15:22:08:123'); INSERT INTO TEST_DT1 VALUES (88,'2023-01-18 16:22:08:123'); INSERT INTO TEST_DT1 VALUES (99,'2023-01-19 17:22:08:123'); INSERT INTO TEST_DT1 VALUES (110,'2023-01-21 18:22:08:123'); INSERT INTO TEST_DT1 VALUES (111,'2023-01-22 19:22:08:123'); INSERT INTO TEST_DT1 VALUES (122,'2023-01-23 20:22:08:123'); Select * from TEST_DT1;Output:
If we check the data for the “Date_time,” we can see that the storage taken for the column is 7 bytes as it saves the precision fraction of (3, 4).

Making The Case For Going Case
I decided to go completely case-less. Most of you guys probably think I already do that, since I never have a case on my devices when I’m filming a new video.
But that, as it turns out, hasn’t been so. I used to only keep my iPhone nude for aesthetic purposes on film. As soon as I hit the shutter release on my camera to stop filming, back in the case she went.
Then I read something that changed my perspective on things. After seeing this post by John Gruber, I started thinking. Why are we so obsessed with encapsulating our devices in protective covering? Aren’t we ridding ourselves of the pleasure of using it as it was intended and designed to be used?
I decided to embark on an experiment. One that could prove costly, but at the same time provide me with a since of liberation. I was going to go case-less…
That was two months ago, and I’ve never looked back. It’s hard for me to imagine ever going back to using a case after using my iPhone 5 without one for the last two months.
I will admit that I have yet to throw caution completely to the wind, not yet at least. I purchased AppleCare+ just in case my phone is cosmetically damaged to the point where it bothers me. I’ve also placed a thin square patch of film on the back on my slate iPhone 5, because the anodized aluminum is so prone to scratches. That being said, it’s barely even there, and it’s certainly not providing me with any real protection in the event of a catastrophic drop.
I’ve received some pretty funny responses from friends, family, and even random strangers upon them seeing my case-less iPhone 5.
“You must be pretty brave to do that,” noted one stranger in a local Starbucks.
“That’s insane!” proclaimed an OtterBox obsessed friend.
Just a few months ago, I would have at least sympathized with them, but now I think they’re downright ridiculous for covering up such a fine piece of hardware. They pay all of this money for a device, and they don’t even get to touch it, can’t even feel it, and can barely see it. It all seems silly to me now.
Of course, going case-less has its downsides. For one, it’s inevitable that you phone will suffer from a few scratches here and there. These scratches are largely unnoticeable without a thorough examination of the device, or without the sun hitting it at just the right angle, but they’re there.
The slate iPhone 5, as you know, is prone to scuffs due to the anodized aluminum coating. I’m a victim of “scuffgate“, and I do notice more than a few areas on my iPhone where the bare metal is showing beneath the coating. Again, it’s not something that’s immediately discernible, but a close up view will reveal the imperfections.
I have to admit, at first, I was kind of annoyed with the hairline scratches on the screen, or the scuffs on the aluminum housing. I began to second guess the rightness of my decision to go without a case. But then I got to thinking, I really use my iPhone. I mean I really use it. As someone who blogs about iOS devices for a living, I put my iPhone through more stress than the average iPhone owner. It truly is a testament to the design of the device, that I only have the few scratches and scuffs that I do.
I’ve dropped my iPhone on a hardwood floor multiple times. I lay it face down or face up on virtually any surface. I’m always placing it in my pocket with keys and other potentially dangerous objects, and yet, it still looks virtually brand new.
All things considered, I do not regret my decision to go case-less one bit; not one iota. It’s such a liberating feeling to be able to directly interface with your device without any barriers. You don’t have to worry about cases interfering with the camera, or being too bulky. You get to truly enjoy an item, which by its very nature, is truly meant to uninhibitedly touched.
How To Change Closed Caption Settings In Windows 11/10
Closed Caption is a feature in Windows 11/10 that lets you read words spoken in the audio portion of a video, TV show, or movie. The Closed Caption in windows is excellent for people that are deaf, so instead of hearing, they can read the words on the screen. In Windows 11/10, you can change the font, size, and color of the Closed Caption.
How to use Closed Captions in Windows 11/10? How to change Closed Caption settings in Windows 11Windows 11 is quite a change from Windows 10, especially with the Accessibility settings, earlier known as Ease of Access settings. A lot of options were added for the convenience of the differently-abled. Other than that, the positions of the existing options were shifted too. If you wish to change Closed Caption settings in Windows 11, then the procedure is as follows:
In the Settings Window, go the Accessibility tab on the list on the left-hand side.
In the right-pane, scroll down a little and you would find Captions under the Hearing section.
In the window that opens, you would find an option for the Theme preview and another to change the Caption style.
How to change Closed Caption settings in Windows 10To change Closed Caption settings in Windows 10, follow these methods below.
Open Settings
On the left pane, select Closed Captions
Change the Caption Font Color, Caption transparency, Caption Style, Caption size, and Caption effect
Preview and exit.
Open Settings.
Now we are on the Closed Captions page.
Caption Font Color,
Caption transparency,
Caption Style,
Caption size, and
Caption effect.
Once the Closed Caption font is customized, the preview of the results will be displayed in the Preview box above.
You can change the background of the Closed Caption in windows by scrolling down to the section Change caption background.
You can also change the Window color and Window transparency.
Under the section Dim window content, you will see the settings for Window color and Window transparency.
If you want to restore the Closed Captioning settings to the default or some settings to default, there is a way to do so.
What is the use of closed captions?Most people use closed captions for understanding videos in which audio is in a foreign language. As effective as that is, it isn’t quite a reason to justify the presence of the option in the Accessibility section of Windows. The reason for that is that it allows people with hearing difficulties to read text mostly in the same language as the audio.
What is the best color for closed caption?The white color is often used for subtitles on your video, but they are difficult to read when there is a lighter background; one of the best colors to use with lighter background is yellow.
Are closed captions through Windows as accurate as those on online streaming platform?No! But here’s the thing. While the closed captions in Microsoft are not written by a person sitting at a desk and listening to the audio, they are smarter than a mere transliteration when the language is different. However, people with hearing difficulties would be reading closed captions of audio in the same language as the audio. That is fairly accurate!
We hope this tutorial helps you understand how to change Closed Caption settings in Windows 11/10.
Travelers Are Going To Love The Iphone 13
Travelers are going to love the iPhone 13
Apple may have spared no hyperbole during its big iPhone 13 event yesterday, but eager travelers may find the most useful improvements didn’t get a mention in the glossy launch stream. Like last year’s iPhone 12 family, there’s 5G across the board from the smallest iPhone 13 mini through to the flagship iPhone 13 Pro Max, but changes in how and where you’ll be able to connect could make a difference.
Apple has long created different versions of the iPhone in each generation, distinguished with different connectivity support for different regions. In the days when CDMA was more relevant, for example, US iPhone SKUs supported Verizon and Sprint’s CDMA networks. Versions of the phones sold elsewhere in the world, however, typically lacked that radio support.
Another layer of interest was added in 2023, when Apple embraced dual-SIM support. Since the iPhone XS, you’ve been able to have a physical nanoSIM card and an eSIM active in your handset, of particular usefulness to those who travel internationally and want both their home and a localized connection to be active. With the iPhone 13 family, though, Apple is adding dual eSIM support.
That means, although there’s still a physical SIM slot, you could ignore it altogether with the iPhone 13 and iPhone 13 Pro. Instead, you could load two eSIM profiles; they’re increasingly used by carriers like Google Fi. Having two of those virtual slots makes it easier for, say, Google Fi at home and a localized eSIM in your travel destination of choice. Or, for that matter, two eSIMs at home: one for work and another for business.
Lending to the international appeal is Apple’s additional band support. As PCMag details, there are five different iPhone 13 variants by geographical availability. Unlike in previous years, where the US-spec model has lacked support for some of the bands used more commonly in international markets, this time around it’s the US-spec iPhone 13 which has the broadest array.
For 5G, there’s a total of 24 bands supported on the US model. That includes all the common bands required by AT&T, Verizon, and T-Mobile’s 5G networks, of course, including US mmWave, but also future European mmWave networks.
If you’re just buying an iPhone 13 off the shelf in your local phone store, you’ll almost certainly be fine with the local model they sell you. However keen travelers – or those wanting to future-proof as best they can – might want to hold out for a US-spec iPhone 13 import. While you may not get the same warranty protection that way, you could find your connectivity is improved as you globetrot.
Preorders of the iPhone 13 family open on Friday, September 17, with the iPhone 13 mini starting at $699, the iPhone 13 at $799, the iPhone 13 Pro at $999, and the iPhone 13 Pro Max at $1,099. Deliveries and in-store sales kick off on September 24, the following Friday.
