Suggested April 2024 Space Expedition: Classic Adventure Is A Dig Into The Past

Design

The graphics are retro with mid-level pixelation. Even though you are looking at low-resolution illustrations, it is higher than 8-bit quality. The color palette is intense with reds, blues, purples, and yellows splashed across the screen.

Most levels put you into a tunnel setting, which means much of the screen is in black with only the moveable spaces lit up. On some levels, the lights have gone out and you are only able to see the surrounding environment in front of you, which can be creepy when you hear the growls of an alien monster nearby.

Players must perform certain actions on different levels, including figuring out how to turn on the elevator, or escape from bolts of electricity. Before each major task, there is a checkpoint. So, if you reach one, be ready for some action shortly thereafter.

Players control the astronaut using a left and right arrow on the left side of the screen, as well as two action buttons on the right.

Gameplay

The game begins with some text explaining the situation. Players must find out what happened on the space station. Some radioactive materials and an accident caused mutations in creatures that turned them into monsters. The first level is dedicated entirely to teaching you how to move, pick stuff up, activate things, and use turrets.

As you move around, you’ll be able to break through the black tunnels simply by running through them or jumping up. Sometimes, you’ll accidentally fall through a loose patch into a lava pit and have to start over, remembering where that hole was. On some levels, the dirt below you will begin to break away slowly and you must get across a chasm before it falls apart, dropping you into the abyss.

Each level has hidden gems on them. They are always hidden in secret rooms that you must find by breaking away the dirt in the black tunnels. At the end of the game, the number of gems you’ve collected will be tallied and added to your score.

On some levels, your ability to move quickly is the most important aspect. A giant spider may chase you, or lava may be filling up inside the tunnel you are in. One mistake or missed jump and you’ll be toast.

At times, you’ll be tasked with shooting down attacking monsters while trying to activate machinery. This fast-paced action does not happen very often, but when it does, it pushes your limits.

For the most part, this is an explorative game with minor challenges. The tasks are not particularly difficult to achieve and finding missing items are not very hard. However, seeking out the hidden gems adds to the enjoyment. Don’t assume you’ve accomplished all there is to a level. Chances are, a hidden gem is still waiting to be found.

The Good

This game, although fitting into the platformer genre, is a casual game at heart. It does not require much of your time and won’t ask for too much exertion.

The Bad

This game is definitely too short. Even though you can replay levels over again in an attempt to find the hidden gems, there are only seven of them. It took me less than an hour to get through the entire game without searching for gems.

Value

Space Expedition: Classic Adventure costs $2.99. In today’s mobile world, that is a premium price to pay for such a game. Because there are only seven levels, I can’t call it a good deal. The replay value is medium. You will want to replay every level until you find all of the gems, but once you’ve done that, there is nothing else to do. The game ends with, “To be continued…” so, my hope is that there are more levels to come in the future.

Conclusion

If it weren’t for the price, combined with the length of time to get through the entire game, I would definitely recommend it to fans of platform titles. However, I know that mobile gamers expect a lot more for their three bucks and would consider the cost to be too expensive. If you don’t mind throwing down a few dollars on a short game, it is fun and worth your time. Hopefully, the developers will add more content, increasing the bang for our buck. This game is available on the iPhone, iPad, and iPod touch. You can download it in the App Store today.

Related Apps

Although the mechanics are completely different, this game has a similar aspect to Skullduggery!

Check If The Rune Is A Space Character Or Not In Golang

Go has built-in support for Unicode . In Go, a code point from Unicode is represented by the rune type. Evaluating a rune to see if it contains a space character or not is one of the frequent actions when working with strings. Several methods for determining whether a rune in Go is a space character or not will be covered in this article.

Using the Unicode Package

Many functions for working with Unicode characters are offered by the unicode package, which is part of the Go standard library. One of these functions is called IsSpace, which gives a result of true if the provided rune is a space character and false otherwise.

Example package main import ( "fmt" "unicode" ) func main() { r := ' ' if unicode.IsSpace(r) { fmt.Println("The rune is a space character") } else { fmt.Println("The rune is not a space character") } } Output The rune is a space character

In the example above, we check if the rune r is a space character or not using the unicode.IsSpace function. If the rune is a space character, the output will be “The rune is a space character”, and if it is not a space character, the output will be “The rune is not a space character”.

The unicode package provides several other functions that can be used to determine whether a rune belongs to a specific Unicode category. For example, the IsLetter function can be used to check if a rune is a letter, and the IsDigit function can be used to check if a rune is a digit.

Using the ASCII Range

In ASCII, the space character is represented by the integer value 32. We can use this fact to determine whether a rune is a space character or not.

Example package main import "fmt" func main() { r := ' ' if r == ' ' { fmt.Println("The rune is a space character") } else { fmt.Println("The rune is not a space character") } } Output The rune is a space character

In the example above, we check whether the rune r is a space character or not by comparing it with the ASCII value of the space character, which is 32.

Using the Switch Statement

We can also use a switch statement in Go to determine whether a rune is a space character or not.

Example package main import "fmt" func main() { r := ' ' switch { case r == ' ': fmt.Println("The rune is a space character") default: fmt.Println("The rune is not a space character") } } Output The rune is a space character

In the example above, we use a switch statement to determine whether the rune r is a space character or not. We use the case statement with the condition r == ‘ ‘ to check if the rune is a space character.

Using the Unicode Categories

In Unicode, a space character belongs to the “Zs” category. The unicode package provides the In function that can be used to check if a rune belongs to a specific Unicode category.

Example package main import ( "fmt" "unicode" ) func main() { r := ' ' if unicode.In(r, chúng tôi { fmt.Println("The rune is a space character") } else { fmt.Println("The rune is not a space character") } } Output The rune is a space character

In this example, we define a sample rune that represents a space character, and use the chúng tôi function to check if the rune belongs to the “Zs” Unicode category, which includes space characters. We then print the result accordingly.

Here is the complete code example for checking if a rune is a space character or not in Go −

Example package main import ( "fmt" "unicode" ) func main() { s := "hello world" for _, r := range s { if unicode.IsSpace(r) { fmt.Printf("%q is a space charactern", r) } else { fmt.Printf("%q is not a space charactern", r) } } r := ' ' if unicode.IsSpace(r) { fmt.Printf("%q is a space charactern", r) } else { fmt.Printf("%q is not a space charactern", r) } } Output 'h' is not a space character 'e' is not a space character 'l' is not a space character 'l' is not a space character 'o' is not a space character ' ' is a space character ' ' is a space character ' ' is a space character 'w' is not a space character 'o' is not a space character 'r' is not a space character 'l' is not a space character 'd' is not a space character ' ' is a space character

In this example, we defined a sample string with space characters and iterated over each rune in the string. We used the unicode.IsSpace function to check if each rune is a space character or not, and print the result accordingly. We have seen how to check if a specific rune is a space character or not by using the IsSpace function with a single rune argument.

Conclusion

Go has a number of methods for figuring out whether a rune is a space character or not. The IsSpace function, which may be used to detect whether or not a rune is a space character, is one of several functions offered by the unicode package that can be used to see if a rune falls into a particular Unicode category. To determine whether a rune represents a space character or not, we can either utilise the ASCII range or the switch statement.

Space characters must be handled carefully when working with strings in Go since they can change how various string operations, such splitting and trimming, behave. You may make sure that your Go programmes handle space characters appropriately and deliver the desired outcomes by employing the strategies described in this article.

Ibm Watson’s Ancestors: A Look At Supercomputers Of The Past

On Monday, the epic three-night Jeopardy battle begins when IBM’s supercomputer Watson will take on the game show’s two greatest champions, Ken Jennings and Brad Rutter. On the line is a $1 million prize, and the pride of both human contestants as well as IBM’s reputation as a pioneer in machine learning.

It’s anybody’s guess who will win tonight, but in honor of what may be Watson’s intellectual triumph over humanity, here is a look at the rise of the supercomputer in human history.

Watson

Watson is based on IBM’s Deep QA project, which is attempting to create computers that can mimic the human ability to comprehend and answer natural language questions. The computer features 15 terabytes of RAM and about 2880 processor cores, can perform 80 trillion operations a second, and is the size of ten refrigerators.

Watson is seen as a giant leap forward in artificial intelligence because to play Jeopardy it had to understand and answer English language questions using idioms and common expressions. This is unlike previous computers, which required specific input keywords before they could respond to human speech.

Colossus Machine

Colossus was the first large-scale electronic programmable computer and was built by the British in 1944 during World War II. Colossus was designed to help Allied forces decrypt messages encoded with the Lorenz cipher sent from German High Command to Nazi officers in the field.

The machine was powered by about 1500 vacuum tubes, received input from paper tape, and sent its output to a typewriter. It took about six hours for Colossus to decrypt a ciphered message, according to a BBC report. A total of ten Colossus machines were built during the war.

Cray-1

The machine cost nearly $9 million and could perform (at top speed) 160 megaflops (160 million operations per second). It conducted these operations with 8 MB of memory.

Deep Blue

Perhaps one of the most legendary supercomputers of all time, IBM’s Deep Blue was developed specifically to test a computer’s capabilities to play chess. The machine featured 30 120MHz processors and performed at 1 teraflop (1 trillion operations per second). This version of the machine played a rematch with world chess champion Gary Kasparov after losing to the champ in 1996 by 4 matches to 2.

Columbia Supercomputer

NASA’s Columbia supercomputer was a collaboration between Silicon Graphics International, NASA, and Intel in 2004.

The system, housed at NASA’s Ames Research Center in Mountain View, California, features 10,240 Intel Itanium 2 processors and 27 terabytes of RAM. Columbia uses SUSE Linux Enterprise as its OS. The machine was designed to help NASA construct large-scale environmental models such as hurricane track prediction and global ocean circulation. Columbia also helps analyze the physics of supernova detonations and other large events occurring in outer space.

NASA says the first super computer at Ames could do 1 billion calculations per second. Columbia is 50,000 times faster than that.

The Jeopardy-IBM challenge lasts three nights, running from February 14 through 16.

Ethereum Price Surges Past Us$4,500! Is It The Right Time To Invest?

The sudden ethereum price has put its market valuation at US$2.7 trillion

The first and foremost altcoin,

Ethereum Price Prediction

According to a previous report submitted by a panel of 42 cryptocurrency experts in October, etherum price was anticipated to breach the US$4,500 mark by the end of 2023 and reach US$10,000 by 2023. However, things have changed upside down now. Even previously some enthusiasts have boosted ethereum’s value to reach the US$10k mark before the end of 2023. However, not many were very positive about the anticipation and thought it was overvalued. But the recent price rally and ethereum’s capability to part away from bitcoin and perform well has brought value to its stance.  

Anticipations and Expectations on Ether

According to some analysts, bitcoin and ethereum were predicted to double their value before the end of the year. While an analyst behind Plan B handle on Twitter has said that bitcoin will reach US$98,000 this month, it also indicated an upcoming ethereum price rally. However, ether has proved that the cryptocurrency can grow on its own without bitcoin’s help. Ethereum is the first altcoin that emerged out of bitcoin’s existence. Usually, ether follows bitcoin’s trend and keeps up with it. Whether it is a price surge or plummet, ethereum will follow the same path as Bitcoin does. But the recent price rally has indicated otherwise. Without a bitcoin price rally, ethereum has experienced a value surge. According to Goldman Sachs, ethereum network could well jump 80% to US$8,000 in the next two months if it keeps tracking inflations expectations. However, they also warned that central banks won’t let inflation rise sharply. JPMorgan has also said that they have seen signs of inflation in the cryptocurrency market. It has driven many investors to hold on to bitcoin and others rather than a gold investment. On the other hand, billionaire investor Mark Cuban has said that ethereum has the most upside as an investment model. He added that because according to him, ethereum blockchain, smart contracts, or collection of code has changed a lot in the cryptocurrency market.  

Why Ethereum 2.0 is a Big Success?

Many anticipated that Ethereum 2.0 could be a big success and might outperform bitcoin soon. They are not wrong. Ethereum saw the difference between the number of tokens issued and destroyed turn negative in the last seven days on aggregate for the first time. This is a tactic that bitcoin has used to trade its digital token since its inception. Bitcoin started its supply with a cap of 21 million. Once this number is reached, we can’t mine anymore bitcoins. The scarcity of the digital token has kept its value in the virtual currency ecosystem. Now, ethereum has boarded the same train with its update to 2.0. Ether is gaining value from a process called burning, where coins are taken out of circulation. Whenever an ether transaction is made, a small quantity of the coin is burned. As more transactions take place, it puts more ether at the cost of burning, which could eventually drive its price. On the other hand, Etherem ETF is also approaching the government approval stage. Although Bitcoin ETF is already on the radar, US regulators are more likely to approve ethereum ETF before giving a green signal to bitcoin.  

So, Is it the Right Time to Invest?

The first and foremost altcoin, ethereum , has skyrocketed to an all-time high with the coin hitting a value of US$4,470 yesterday. At the time of writing, the cryptocurrency’s value has surged even more and was being traded at US$4,556.70 with a 5% 24-hour growth. The sudden growth has put ether ’s market valuation at US$2.7 trillion, giving a stronghold to the second most adopted digital token in the cryptocurrency market. But what triggered the ethereum price when bitcoin is still maintaining a moderate value for a week straight? It is the metaverse and NFT announcements. Ethereum is expected to expand its service range to the metaverse. Metaverse is a digital space where you can work, play, or even create a community in the digital environment just like the physical one. On the other hand, ethereum has also come forward to tell that its technology is being used to sell the digital craze, non-fungible tokens (NFTs). In a nutshell, ethereum price has gained over 1,000% in the past year. Owing to the increasing adoption of disruptive methods, ethereum price is predicted to skyrocket to further highs in the coming days. Some enthusiasts even suggest that ether will breach its US$10,000 resistance by this year-end. In this article, we explore the price predictions of ether and talk about the right time to invest in a profitable cryptocurrency.According to a previous report submitted by a panel of 42 cryptocurrency experts in October, etherum price was anticipated to breach the US$4,500 mark by the end of 2023 and reach US$10,000 by 2023.

Even investing in the dip is not a wise method. So if you are planning to try your hand on ehtereum, you can do it right away. But make sure you invest an amount that can be handled in case of value decrease.

Pebble Time Review: A Modern Day Smartwatch, That’s Stuck In The Past (Video)

Pebble Time is an interesting smartwatch. This is a bit different from anything else out there in the sense that it’s super low-tech. There’s absolutely nothing flashy about it. As far as smartwatches go, this is as barebones as it gets, but is that bad thing?

I’ve been wearing Pebble Time for about a week now and being an owner of the last generation, this was extremely easy to get used to. Pebble Time’s design is thinner, lighter, and more comfortable to use than its predecessor. It definitely feels like a second generation product, but still feels a bit behind in certain areas when compared to Apple Watch or Android Wear. The materials being used are mostly plastic, but there is a nice metal bezel around the outside (of the inner bezel) and Gorilla Glass covering the screen. Pebble Time is also water-resistant and feels quite durable.

Pebble Time features a colored backlit e-paper display, that’s easy on the eyes and works good enough to make your way through the menus and options Pebble Time has to offer. The company’s new Time OS is a re-imagining of the software you’ll use to navigate it. Everything on Pebble Time is controlled with four buttons. Animations are snappy and fun and the interface is very smooth, but you won’t find any touch screen here.

Check out our Pebble Time review video below:

One of the main features here is Pebble’s Timeline. This is accessed from the main screen using the up and down buttons on the right side. This is essentially just a look into the past and future based on your calendar events. From an event you can dig deeper to find out more information about it or you can remove it. I never found much use for it, but it’s a handy feature to have.

Within the Pebble Time companion app, you’ll find additional watch faces that can be downloaded, along with third-party apps for things like Twitter, Philips Hue, and Nest to name a few. The companion app is very straight forward and easy to use and apps can be arranged in a custom order. Pebble’s developer community is pretty strong and there’s a lot to discover here, but I really only ever cared about having notifications on my wrist.

The main reason I used Pebble Time was for notifications. When each notification arrive, you’ll feel a solid short vibration on your wrist. Unfortunately, it’s quite limited when compared to native smartwatch solutions on both iOS and Android, but one thing is clear: Pebble Time is much more useful if you’re using an Android device. A lot of what makes this a good smartwatch is currently unavailable for iOS users.

Three major things about Pebble Time and iOS that are extremely annoying:

There’s no granular control of notifications on iOS. It’s all or nothing here, unless you’d like to disable those app’s notifications on your iPhone as well.

There’s no way to prevent your iPhone from buzzing if notifications are being displayed on Pebble Time.

There are currently no voice replies using Pebble Time’s build in microphone.

To be fair, I think these limitations might have to do with restrictions in iOS. Pebble notes that voice replies to Gmail notifications are coming soon, but currently there’s nothing else to look forward to with Pebble Time on iOS. On Android, this is a completely different experience. Everything I’ve mentioned works great across all compatible apps and services. Pebble Time’s voice dictation feature will work with hundreds of apps already available on Android.

The best feature Pebble Time has to offer is its battery life. I used Pebble for four days straight and still had 40% battery life. Regardless of anything that’s limiting Pebble Time’s functionality, there’s definitely nothing standing in the way of battery life.

The real story here centers around the new hardware and software design. It’s nice for sure, but not the prettiest looking smartwatch available. Here’s the bottom line: Is Pebble Time a must-have smartwatch? Nope. Are there better solutions available? Yep. Pebble Time only set me back around $180, but I’d rather pay a bit more (or less in the case of certain Android Wear devices) for something that offers native integration on either iOS or Android. I’m sure software updates will improve Pebble Time in the future, but as for now, it feels like it’s stuck in the past.

How To Use The Histogram In Lightroom (Classic & Cc)

Photographers have a very valuable tool available to help them edit their photos – the histogram in Lightroom. This is one of the more underrated editing companions because, while powerful, it can be hard to understand (especially for those looking at it for the first time). 

The histogram can make adjusting your exposure much easier, indicating exactly where the exposure falls flat or is too much in your highlights, shadows, and mid-tones. 

What Is A Histogram? 

In a nutshell, a histogram is a graphical representation of your photo’s exposure. The “hills and mountains” represent the shadows, highlights, and mid-tones. The graph aims to show you how dark, light, or just right each of these tones is. 

The histogram isn’t just a tool that exists in Adobe’s software. You have one on your camera itself. While adjusting your exposure settings to take a photograph, you can view a histogram of the scene before taking the shot. This can give a better idea of whether the exposure settings are underexposing, overexposing, or a good middle ground for the image. 

While the histogram on the camera aims to help you capture a better photo, the availability of this tool in both Lightroom Classic and Lightroom CC enables you to edit your image’s exposure more precisely. 

Where Is The Histogram Located In Lightroom?

You can find the histogram in both Adobe Lightroom Classic and Adobe Lightroom CC, although the graph is located in different places between the two programs. 

The Lightroom Classic Location

In Lightroom Classic, you can find the histogram in both the Library module and the Develop module. 

The histogram in the Library Module is at the top of the right-side panel above Quick Develop. 

If this right side panel isn’t immediately visible, press the arrow icon in the middle of the right side of the program screen. 

In the Develop module, the histogram is located in the same location but is now above the Basic tab. Again, if this right side panel is hidden, press the arrow symbol. 

The Lightroom CC Location

Close-up of the Edit symbol

From the edit view, you can find the histogram located in the right-hand corner above the Light tab. 

This will bring up an options window from which you can restore the histogram view. You can also press Control + 0 (Win) or Command + 0 (Mac). 

How To Read The Histogram In Lightroom

Reading the histogram is not as complex as it may seem on the surface. The histogram is divided into three primary sections: 

Shadows: 

Mid-tones: 

Highlights: 

Technically the histogram is divided into five sections because the chart is a very detailed representation. On the far right side are your Whites (brighter than highlights), and on the far left are your Blacks (darker than shadows). 

But it is easiest to think of the chart as being made up of three primary sections when editing. 

The peaks and valleys of the “mountains” represent how much shadows, highlights, and mid-tones are present in a photo. 

If you have a lot of tall peaks on the left side of the screen, that means your image is underexposed. You have a lot of shadows and not a lot of highlights or mid-tones. Here is an example of an underexposed image with the histogram skewed to the left as a result: 

On the contrary, an overexposed image would have a histogram that is skewed to the right. This indicates that there are a lot of bright tones in the picture. 

An image lacking contrast will have a histogram with no peaks and mountains on the shadows or highlights (far-left and far-right sides of the screen). The tall peaks will be in the mid-tones.

An image with a good or even exposure will have a cluster of mountains, more so in the middle of the histogram, spreading across the entire chart. 

The Histogram And Color

Notice that the histogram graphs also have “mountains” with colors. The colors represented are red, green, and blue (primary colors). Where they mix, you’ll find yellow, cyan, and magenta. The gray is where all of these colors mix.

This indicates how much of that color (or colors) is present in that tone. So, the histogram has the added bonus of representing color distribution in your tones!

For example, you can see a lot of blues in the Highlights section of this photo. That states that the highlights have blue in them. 

The Histogram And Clipping

The histogram also indicates a tonal issue known as Clipping. Clipping is when there is a loss of information or detail on the extreme end of the shadow spectrum and/or the highlight spectrum.

Generally speaking, photos look best when you can see detail in the entire range of tones, from the darkest to the lightest. If your shadows are clipped, that means you have lost information in the darkest part of your image. Likewise, if your highlights are clipped, that means your image is overexposed. 

The histogram indicates when your shadows or highlights are clipped with an arrow icon on either side of the screen. 

The arrow turns gray on the left side when your shadows are clipped. 

When your highlights are clipped, the right arrow is gray. 

How To Edit Your Photos Using The Histogram In Lightroom

With all of the information that the Lightroom histogram shows, editing becomes a lot more technical. You can see in real-time how your exposure adjustments impact the image, not just by the changes within the image itself but also by how the graph adjusts.

Use the histogram to fix the tones in your image that are shown to be an issue. The histogram also helps you edit by stopping you from going overboard with your adjustments and causing blown highlights or dark shadows. 

For example, let’s take this underexposed photo, and I’ll walk you through how the histogram helps me fix it: 

As you can see, there are too many blacks and shadows here, so the image appears very dark. The gray arrow on the left side is marked, indicating clipping there. 

To adjust this, I will go to my Basics tab and move the Exposure slider to the right to lighten the image. I move the slider until the clipping arrow on the left side is no longer gray. 

But, as I moved the exposure slider to the right, more highlights and whites appeared, which meant that although my shadows were corrected, my highlights and whites suffered because the arrow now indicates clipping on the right side of the histogram. 

To counteract this, I pulled my Whites and Highlights sliders down until the arrows no longer showed clipping. 

This resulted in my histogram showing that there is no more clipping present in my image (because neither arrow was colored light gray) and that my picture is now well exposed. 

For the overexposed image, I used the histogram to see how far I could edit that image to my liking without causing more clipping. 

The original: 

After my edit: 

The above being said, the histogram is not a law you have to follow. The histogram is more of a guide, suggestion, or reference and should be treated as such.

There are situations where following the histogram perfectly won’t do you any favors – such as editing in a Light and Airy style, landscape sunset images, or adjusting nighttime photographs. 

For example, how I would edit a photograph like this is not conducive to what the histogram tells me. 

My edit would result in a histogram that looks like this, showing that I didn’t resolve the shadow clipping – but that’s because I felt like the shadows enhance the image.

Editing is as much a matter of opinion and aesthetic as it is what a computer graph tells you – use your best judgment.

Using The Histogram Clipping Warnings In Lightroom To Improve Your Exposure

To elaborate a little bit further on clipping, the Lightroom histogram can show you exactly where the clipping is happening directly in your image. 

Let’s take the overexposed image once more. 

If you hover your mouse over the clipping arrow on the right side, the photo lights up to indicate exactly where the highlights are clipped. Highlights are clipped in red.

You can do the same for the shadows, which are clipped in blue.

If you need the clipping highlights (or shadows) to remain visible after you move the mouse, just press the arrow. 

As you edit and adjust your image, the bright red or blue will disappear (because you’ve fixed the clipping issue) or appear even more prominent (because you’re causing clipping). You can use these clipping warnings to gauge your edit’s progress. 

Clipping warnings can also be very important for those looking to print the photo they are editing. Clipped highlights and shadows will not print well because of the lack of detailed information. Adjusting clipped highlights and shadows before printing helps save you money from having to reprint an image because it didn’t come out correctly.
