Suggested January 2024 One Of Bloomberg’s Sources Told Them Chinese Spy Chip Story “Didn’t Make Sense”

Bloomberg said that its sources were key to its decision to run the Chinese spy chip story, the site writing that ’17 people confirmed the manipulation of Supermicro’s hardware and other elements of the attacks.’

Hardware security expert Joe Fitzpatrick was quoted in the piece saying “the hardware opens whatever door it wants.” But speaking on the podcast Risky Business, he painted a very different picture.

Fitzpatrick says that he spent a lot of time explaining to Bloomberg how such attacks could, in principle, be carried out. When the piece was published, he was expecting to read about how this specific hack was achieved. Instead, he said, Bloomberg appeared to be parroting the precise theory he had outlined.

I spent a lot of time going back and forth explaining how hardware implants worked. And as any researcher is excited to talk about their work, I was delighted to have someone who seemed interested to actually learn about how things worked as opposed to only looking for the buzzword byline that you wanted to throw into a story […]

But what really struck me is that like all the details that were even remotely technical, seemed like they had been lifted from from the conversations I had about theoretically  how hardware implants work and how the devices I was making to show off at black hat two years ago worked […]

It was surprising to me that in a scenario where I would describe these things and then he would go and confirm these and 100% of what I described was confirmed by sources.

He said the same was true of the image Bloomberg provided of the supposed spy chip.

In September when he asked me like, “Okay, hey, we think it looks like a signal amplifier or a coupler. What’s a coupler? What does it look like?” […] I sent him a link to Mouser, a catalog where you can buy a 0.006 x 0.003 inch coupler. Turns out that’s the exact coupler in all the images in the story.

When reporter Jordan Robertson outlined more of the story he planned to run, he told them it didn’t make sense.

So late August was the first time Jordan disclosed to me some of the attackers in the story. I heard the story and It didn’t make sense to me. And that’s what I said. I said wow I don’t have any more information for you, but this doesn’t make sense. I’m a hardware person. My business is teaching people how to secure hardware. Spreading hardware fear, uncertainty and doubt is entirely in my financial gain. But it doesn’t make sense because there are so many easier ways to do this. There are so many easier hardware ways, there are software, there are firmware approaches. There approach you are describing is not scalable. It’s not logical. It’s not how I would do it. Or how anyone I know would do it.

[He wrote to Robertson] Are you sure there is actually an additional hardware component […] It’s trivial to modify the firmware of most BMC and many of them are trivial to exploit remotely because of the poor quality outdated software they run. The attack you describe could easily be implemented in BMC firmware. Would be just as stealthy and far less costly to design and implement. If they were really implants, are you sure they were malicious?

Fitzpatrick explained to Robertson several more likely theories for what the site’s sources were claiming to have seen, all of them perfectly normal.

For example putting two pieces of silicone in a single package makes sense when one of them is flash storage and the other is a micro controller. But an experienced observer could easily jump to the conclusion that it’s a hardware implant. Likewise, lots of small components are actually several component manufactured into a single package for an ease of use.

He also explained the context of the one-line quote Bloomberg used.

You put hardware in a device to help you persist the software, the malware. You don’t put hardware in a device to do the whole attack, you put hardware in the device to unlock the keys, to elevate the privileges on the shell, to open the network port and then you take a software or remote approach to do the rest of the work. And I think that’s the context of that quote.

His overall take on the piece is that the technical details are ‘jumbled’ and ‘t

hey’re not outright wrong, but they are theoretical […] 

I definitely have my doubts on this one.’

So let’s make that not five or nine reasons to doubt the story, but ten …

Update: A Bloomberg News spokesperson told us “As is typical journalistic practice, we reached out to many people who are subject matter experts to help us understand and describe technical aspects of the attack. The specific ways the implant worked were described, confirmed, and elaborated on by our primary sources who have direct knowledge of the compromised Supermicro hardware. Joe FitzPatrick was not one of these 17 individual primary sources that included company insiders and government officials, and his direct quote in the story describes a hypothetical example of how a hardware attack might play out, as the story makes clear. Our reporters and editors thoroughly vet every story before publication, and this was no exception.”

What Are Spellbreak Elements? Learn About Each One Of Them Here

Spellbreak is winning hearts everywhere with its cool theme and spellcasting action packaged in the form of a Battle Royale game. More importantly, though, the game has been designed to ensure that no matter how varied the user’s playstyle is, it will not just be able to accommodate the player, but also give them resources in the form of magic elements to thrive and level up. Any Breaker worth their salt knows by now just how important Spellbreak Elements are since they power up gauntlets and cater to different playstyles depending on which element the player uses.

However, there is a learning curve involved when it comes to mastering Spellbreak Elements. Mostly because there are a lot of them and you need to familiarize yourself with the different elemental combinations to be effective in battle. Besides this, a basic understanding of the elements will help you to choose your class and get more wins in the game. So without further ado, let’s understand everything there is to know about Spellbreak Elements.

Spellbreak Elements List

There are six major Spellbreak Elements that your gauntlet can wield. Each element embodies a certain aspect of nature and the user can imbue their gauntlets with the element of their choice. Elements can be used to perform either a direct spell (for a concentrated singular attack) or a bewitch an entire area with sorcery ( to affect a large area and temporarily slow down your enemy). Let’s look at each element now.


Frost is the element that allows the user to use ice for attacks in a battle. When a Breaker chooses Frost, they are capable of casting a spell that will launch powerful shards of ice like a spear or lance. This Ice Lance attack, though capable of a damage range between 15-45, is very expensive and will cost you Mana that ranges between 30 and 60. Using Frost, the breaker is also capable of wielding a powerful form of sorcery known as Flash Freeze attack which temporarily freezes an area, slows down the opponent inside it, and even freezes them from two seconds depending on the range of the attack.

Fire is a fan favorite, especially because of how it enables the caster to send a powerful scorching Fireball spell flying towards opponents to cause critical damage. The Fireball spell has a decent range ensuring that it not just explodes on contact but also creates some damage based on the proximity to the center of the explosion as well as by lingering as a flame puddle for six seconds if it hits the ground. Fire mages are also capable of casting a powerful Firewall using a Sorcery spell. Whether it’s to block Frost attacks or Toxic fumes, the Firewall acts as a powerful defense that can burn your opponent if they try to cross it. Keep in mind that Fire is a major mana consumer just like Frost.

Corrosion is the crux of all Toxic attacks which is what makes it so destructive in the first place. Toxic requires good aim and is best used in the face of multiple enemies should you come across them. A spell will allow you to shoot 10 streams of toxic jets that will induce damage depending on how many hit your opponents. But it is in the form of a Toxic cloud that this element truly thrives. The major issue that crops up with Toxic is that it hits the caster as well even though the damage is not as bad as it is for the enemy. Nevertheless, at a consumption rate of 20, the value-for-mana and damage induced by this element make Toxic super worthwhile for us.


There is no beating the Stone element in terms of damage however you will also have to sacrifice major mana depending on the nature of the attack. But, even Shockwave, which is considered to be the Stone element’s offensive weapon and requires lesser mana than the sorcery attack, causes a massive eruption of the ground to travel through it and attack the opponent in a powerful impact. The major Stone attack which requires sorcery will cast a massive stone Boulder or Boulderfalls, as they are called, that the caster can propel towards their opponent. Based on how good your aim is, how long the Boulder stays in the air, and your opponent’s proximity to the center of impact, Stone could make or break a battle for you.

If you love the last Airbender then you will love the Wind Shear spell. Quick rapid gusts of wind don’t just damage your opponents but also act as a good defense to deflect their spells. The mana consumption is fairly less for Wind as it ranges between 8 and 9 and considering the attack range extends between 5 to 20 meters, that’s good value-for-mana. If you want to perform sorcery using Wind, then you get to be the caster of a powerful wind tornado that will pull your opponent into a powerful vortex.

Each element is great in its own way and there’s a possibility that you already have an inclination towards one element. But remember that Spellbreak itself is an intricate game and there are circumstances or situations in which certain elements will become a liability. Like when you’re in a terrain with a lot of rifts, Stone will be useless, similarly, there won’t be much you can do with Stone in an aerial battle. There might also be close-range battles in which elements like Toxic and Fire might destroy you before it does anything to your opponent. So remember that while there are certain scenarios in which an element can be a total asset against another one, the opposite might happen simply because of a variable thrown at you by the game so you need to be careful in your choice.

How elements react with each other

Understanding the nature of each element and how they work is only one aspect of the entire whole that is Spellbreak elements. As a Breaker, you will be wielding two gauntlets at a time with two elements of your choice as well as their spells and sorceries. Besides, you will also be facing off with other Spellbreakers who will be wielding two gauntlets themselves. Spellbreak as a game has been designed to allow you the use of these elements in different permutations and combinations which is why it’s important to understand how these elements interact with each other.

Frost and Lightning

Lightning disables Frost magic in a big way with lightning bolts electrically charging ice puddles and water puddles that comes in contact with it. Lightning bolt spells are capable of beating Frost’s attacks in a battle. So the Frost users need to approach Lightning magic smartly and look for opportunities to turn their weakness into their enemy’s defeat. If you use them in a combination, be careful about the way you cast these element spells so as not to injure yourself in the process.

Frost and Fire

Frost and Fire have an interesting relationship. Fireballs turn ice puddles into steam puddles on direct contact making those puddles even more lethal while Frost has the ability to extinguish both Flamewall and Fireball attacks. But keep in mind that you cannot use Flash Freeze inside a Flamewall and a Fire user can obliterate you if they trap you inside one. So while Frost can be used both defensively and offensively in a battle against Fire, a Fire wielder can dominate a Frost magic with the right moves too. With these elements and their contrasting magic, it can be anyone’s game depending on the right strategy.

Frost and Toxic

Toxic’s effect on Frost is almost overwhelming because a Toxic attack turns ice puddles into Toxic puddles on contact with the puddle or a player standing on one. Even Steam Puddles turn into small Toxic Clouds when in contact with Toxic. Toxic Streams can also block a Frost attack in a battle. However, a Flash Freeze attack turns Toxic Puddles into unharmful Toxic Ice Puddles, thus neutralizing the element similarly and another benefit is that Frost can be used to freeze Toxic into ice projectiles. So depending on the Frost attack that you employ, you might be able to overwhelm Toxic.

Frost and Stone

Stone’s powerful offensive moves Shockwave and Boulderfall both shatters Ice Puddles and blocks, creating Ice Mists in their place. Stone is a great neutralizer element in general so this will be the norm even with other elements. In an attack, the more mana you give, the better you will perform as a Stone element user against other elements.

Frost and Wind

A wind shear attack will shatter ice puddles upon contact to create ice mists in their place. If you want a defensive spell, then Wind Tornado will not disappoint with its ability to affect the trajectory of Ice Lance shots and dispel any Ice Puddles and Ice Mists in its radius. Wind has a major defensive upper-hand against Frost.

Lightning and Fire

Any form of Lightning attack passes through a Flamewall or Fireball attack. Both are evenly matched in a fight and victory is heavily dependent on the caster as well as how much mana they are willing to dedicate towards the destruction of their opponent.

Lightning and Toxic

As with all other elements, Toxic enables Lightning as well. While a Lightning attack can be blocked by a Toxic Cloud and Spray, the Bolt also electrifies the cloud in the process. So the cloud which is now electrically charges can shock all players in a 10-meter radius. Lightning also electrifies Toxic Puddle on contact with them directly or a player standing on one. Both users can turn their respective elements against each other, so a careful approach with Toxic is extremely important.

Lightning and Stone

In a fight against Stone, the likelihood of Lightning losing is fairly certain. Stone attacks Shockwave and Boulderfall can easily overwhelm and block Lightning if executed with perfect timing. The only means to win against Stone is to have the perfect and powerful lightning strike in place to stop a Shockwave attack in its tracks.

Lightning and Wind

It seems like Lightning and Wind are best friends because a Wind Tornado’s gravity doesn’t affect the trajectory of Lightning Bolts and even if hit directly, the Tornado only absorbs them and becomes a Lightning Tornado. Similarly Wind Shear carries Lightning shocking players on impact. In a fight that involves these elements, both opponents are evenly matched.

Fire and Toxic

Fire and Stone

The Fire and Stone relationship is fairly straightforward. A Boulderfall attack can be set ablaze to generate a large Flame Puddle on the ground.  Against a Shockwave attack, you will see a Fire Trail left in the path of your attack. However, keep in mind that Stone being the great neutralizer will be able to block Fireballs with a powerful shockwave attack.

Fire and Wind

Avoid going against Fire with Wind and vice versa. Not only does a Tornado overwhelm Fireballs by changing their trajectory but also become a Fire Tornado if the spells are powerful enough from both sides. Wind attacks can also absorb Fire attacks making Wind a great defense against Fire. To add to the woes of a Fire user,  Wind Shear spells can extinguish an unlimited amount of Flame Puddles and even parts of the Flamewall. Try to avoid confrontations with a Wind user if you’re a Fire mage.

Toxic and Stone

Stone is probably the only element against which Toxic is very vulnerable. A Boulderfall spell can block a Toxic Spray and collide with the Toxic Cloud projectile to overwhelm it. It can also remove Toxic Puddles on impact. There is not much that Toxic can do against Stone because a Shockwave attack also removes Toxic Puddles from the ground and passes through Toxic Clouds being neutralizer element. Basically Stone users have the best defense and offense against Toxic users so the Toxic users will find themselves heavily dependent on their second element.

Toxic and Wind

Toxic and Wind elements are equally matched so the strategy that you apply will play a very crucial role in this kind of battle. Wind as an element is primarily focused on reacting with other elements. So a Wind Shear spell will create a Toxic Mist upon impact. You should also keep in mind that a Wind Tornado’s center of gravity affects the trajectory of Toxic Spray heavily which turns it into a defensive attack by dissipating Toxic Cloud projectiles as well as any Toxic Mists, puddles, or clouds in its radius. However, if the Toxic is more powerful, then expect to see a Toxic Whirlwind and if ignited,  a Tornado explosion. tread carefully with this combo.

Stone and Wind

Both Stone and Wind are also evenly matched in a battle. While a Wind Tornado’s gravity is capable of changing the trajectory of a Boulderfall spell, there are very little Wind users can do in the face of a Boulderfall spell when Wind Shear sorcery. The spellcaster needs to approach these elements very thoughtfully to land a win because both are heavily focused on disabling each other.

Now that you understand how the Elements work together and against each other, it will be much easier to decide your own combo. Make sure that you choose wisely.

Class and Element association

Players in Spellbreak must choose a Class before each match depending on what kind of skills they will need for the forthcoming battle. Each class has been set against an Element and choosing that class will entitle you the privileges of its element. During the battle, you will have your common gauntlet with the Element you’ve chosen to go with regardless of your class along with the Element that represents your class. Each class has four levels of mastery and different time requirements for mastery. To be at the helm of the game, you must master all classes.

Let’s understand the Class and Element association now.


Frostborns use Frost as their element. It is a preferred class for long-range battles and the recommended talents are Focused Mana, Fortitude, and Thirsty. Being Frostborn will give you high mobility however you will be susceptible to Harmony talents which will be able to freeze and temporarily immobilize you. Being Frostborn also means a massive mana consumption so you need to be sure that you are equipped before choosing this element.


Conduits use Lightning as their element. Consider choosing Conduit if you’re in a long-range battle or in a battle against Air users. You need to be good at executing projectile attacks and evading enemy attacks if you want to play in the Conduit class. The required talents are Harmony, Fervor, and Recklessness. A major downside to being a Conduit is that you will be very susceptible to the sorceries of other elements so tread carefully with this one.


A Pyromancer wields fire to inflict long-lasting effects on their enemies. When you choose to play as a Pyromancer, the recommended talents are Tracking, Fervor, and Recovery because casting Fire spells leave the caster extremely vulnerable. You will have to be in the front lines when you cast Firewalls for protection and create defense lines. Also, wielding fire as a Fireball spell might leave you vulnerable because of its slow projectile speed. There are both upsides and downsides to using fire depending on your opponent and terrain. Gauge your situation and proceed accordingly.


Toxicologists wield poison in their arsenal in the form of Toxic. You can cause slow damage as a Toxicologist by using Toxic puddles and sprays. We recommend being a Toxicologist if you have a battle-ready common gauntlet like Fire, Frost, or Lightning which work well in combination with Toxic. Remember that Toxicologists are weak against Pyromancers and Tempests who have the elements and spells required to overwhelm the corrosive power of Toxic. The recommended talents for you are Runic Fluency, Scavenging, and Vital Stone, all of which help to protect and empower you as a Toxicologist.


Stoneshapers use Stone as their Element. A major kryptonite in the case of Stoneshapers is how heavily terrain dependent they are. All Stone attacks require some form of contact with the ground so despite how powerful the attacks are and how much despite how neutralizing this element is against others, you need to consider the Geography before choosing to be a Stoneshaper. The recommended talents for Stonershapers are Runic Fluency, Fervor, and Thirsty.


Finally, the most mobile of all classes, Tempest users wield the sublime power of Wind to overwhelm opponents. Tempest users can harness Wind Tornados against every other element very effectively because of how Wind interacts with all of them. There is a downside to these interactions as well because as a Wind user, you are also susceptible to the common gauntlet that you choose and your defense is a bit weak making you susceptible to elements with projectile capabilities. The recommended talents for Tempest are Spellslinger, Fervor, and Recovery.

We hope these Class and Element interactions will help you decide your own class the next time you play Spellbreak.

Best Spellbreak Combos to use

Element strategies refer to your plan of action when you enter the game. Spellbreak makes you choose your class and elements before each battle, so you can be assured that no two matches will be the same. This coupled with the different combinations of elements as well as how they interact make the need for an element strategy very crucial. While you have to make the final decision, doesn’t mean it can’t be an informed one.

Check out this article for the full list of combos as well as ideal elemental pairings that you must consider before your next Spellbreak match.

Until the next Spellstorm! Take care and stay safe.


Making Sense Of Astronomical Valuation Of Tesla

This article was published as a part of the Data Science Blogathon.

Opinions on Tesla Price ($672, $677B Market Cap)

It is fair to say that Tesla is one of the most polarizing stocks of our time. On TipRanks, the 1-year prediction of the stock price ranges from a low of $67 to a high of $1,200. That is a staggering difference of about 20x. Even when looking for guidance from the most esteemed analysts of our time, we get extremely polarized views.

・”What do $TSLA, $BTC, option gamma traders have in common? Rhymes with Rubble” —  Michael Burry (Legendary Big Short Investor), 11/2023

・”Our confidence in Tesla has been rising. With their improvements and leadership in autonomous vehicles, battery technology, AI.” —  Cathie Woods (ARK Invest CEO), 02/2023

Yet, Tesla continues to be a company that is difficult to grasp due to its unpredictable moves: shocking purchase of $1.5bn Bitcoin, continuous controversial tweets from Elon Musk, and news about their blowout earnings in Q12023.

This made me want to look at the actual key metrics of Tesla’s valuations and how it compares to other companies. I aim to explore how exactly outrageous Tesla’s stock price is compared to other companies.

Methodology (Scraping with Python Finance API)

I have decided to use a list of 60 companies from the Healthcare, Technology, and Automotive Industry. The market capitalization of these companies is mostly over $100bn, making them large caps.

I wanted to include both the Technology and Automotive Industry, because Tesla is always argued to encompass both sectors, and I also wanted to add another unrelated industry (Healthcare) to give it some more ground for comparison.

The full list of the ticker symbols used for the analysis is below:

['AAPL', 'MSFT', 'MSF.BR', 'TSM', 'NVDA', 'ASML', 'INCO.BR', 'INTC', 'ADBE', 'ASML.AS', 'ORCL', 'CSCO', 'CIS.BR', 'CRM', 'AVGO', 'ACN', 'TXN', 'SHOP.TO', 'SAP', 'QCOM', 'SHOP', 'SONY', 'IBM', 'AMAT', 'INTU', 'SQ', 'NOW', 'UBER', 'MU', 'JNJ', 'UNH', 'RO.SW', 'PFE', 'ABT', 'MRK', 'NVS', 'ABBV', 'TMO', 'LLY', 'DHR', 'MDT', 'NVO', 'MRK.PA', 'AMGN', 'BMY', 'AZN', 'SNY', 'SAN.PA', 'ISRG', 'CVS', 'SYK', 'TSLA', 'F', 'GM', 'VWAGY', 'TM', 'HMC'] 2. Comparing key valuation metrics of Tesla with other companies

To understand Tesla’s valuations, I have decided to use market capitalization and PSR (Price-to-sales ratio). PSR is calculated by taking a companies’ market capitalization divided by its revenue.

I decided not to use the P/E (price to earnings ratio) because some high-growth companies do not yet have earnings.

To extract the metrics, I will use a great finance API called fmpcloud. You can get a free API for a daily limit of 250 calls.

After you create a list of the stocks you want to analyze, you can iterate over each stock to get the key metrics using the code below. I have used Jose Manu’s code as a reference that he introduces in this article.

With the below code we can get various key metrics

・Operational metrics (all annual): Gross Profit Ratio, Operating Income Ratio, Net Income Ratio, Revenue, Revenue Growth, EBITDA Growth

・Financial metrics: Market Capitalization, Price-To-Sales Ratio

After collecting the necessary information about Tesla’s valuation in comparison with other companies, I wanted to use operational metrics (profitability, size, and growth) to make sense of Tesla’s valuations.

Analysis and Drawing Insights Insight #1: Tesla’s valuation is definitely on the hefty side. But so is the semiconductor industry.

Typically a SaaS company has a revenue multiple of 10, which is where Apple, Google, Facebook all lying around.

In comparison, you can see that Tesla’s PSR is over 20 (PSR of 23.1), which is twice GAFA’s. Looking down the list, however, you can see that Nvidia (NVDA) and ASML also have a PSR close to the 20s.

This shows that the semiconductor industry also enjoys high valuations. On the other hand, healthcare is valued quite low.

The below graphs compare a company’s PSR with Gross Profit and Operating Profit Margin. Each bubble represents a company.

You can see the positive correlation between profitability and PSR, suggesting that the higher the profitability, the higher the valuations.

However, Tesla goes against this trend, as an obvious outlier. Other automotive companies (blue) have similar profitability but their PSRs are 1/20th of that of Tesla.

By the way, there is one company with a whopping PSR of over 50. It is Shopify, which is absolutely incredible.

The below graphs compare a company’s PSR with Revenue and Operating Profit.

When looking at revenue (left), you can see that Tesla’s PSR is high compared to other companies with a similar revenue (~$30bn). Also, Tesla has a high PSR considering its market cap of over ~$500bn.

Created by Author, PSR vs Revenue/Market Cap, Bubble Size = Market Cap (Left), Revenue (Right)

Insight #4: Tesla’s high growth rate (in profits & revenue) starts to justify the valuations.

The below graphs compare a company’s PSR with Revenue Growth and EBITDA Growth.

When looking at Revenue Growth (left), you can see that Tesla’s revenue growth is quite high compared to other companies. In the automotive industry, they have all experienced negative revenue growth while Tesla is growing at about 30%.

It is quite remarkable to see Tesla’s growth despite the pandemic and semiconductor shortage.

Also when looking at EBITDA Growth, you can see Tesla’s growth is by far the highest. I believe that Tesla’s valuation soared to a great degree due to it reaching a profitable business model (I understand there is debate about this too due to the revenues in regulatory credits).

On a small note, you can see that Shopify’s valuation is truly the one that is the most astronomical.

                            Created by Author, PSR vs Revenue/EBITDA Growth, Bubble Size = Market Cap

Final Thoughts

In conclusion, I believe the charts help to show the degree to how Tesla’s valuation stands out in comparison to other companies. With its current profitability and growth, Tesla’s valuation is definitely high. Which makes it a difficult buy for investors, especially for institutions.

But you cannot deny that Tesla’s growth is nothing short of remarkable. When looking at the overall picture, Tesla is still at a very early stage of its lifecycle with most of its growth and technology yet to unfold.

Ramp-up of vehicles, autonomous technology, solar energy business, and the development of an AI platform, are all still in the making.

I believe upcoming earnings will continue to blow out expectations. An interesting quote is hidden in the 10-Q of their FY2023 Q1 earnings:

During the first quarter of 2023, the operational milestone of annualized revenue of $55.0 billion became probable of being achieved and consequently, we recognized a catch-up expense of $116 million.

This suggests that Tesla is fairly confident to reach a revenue of $55bn in 2023. This is a revenue growth rate of 77% from $31bn in 2023. Wow.

However, value is truly in the eye of the beholder. You can walk away from the hefty valuations or buy into the disruptive growth promised by Elon. For this reason, Tesla is and will continue to be a company with strong disagreements.

How To Make A Simple Desk Using Only One Sheet Of Plywood!

Sharing is caring!



This simple desk is made from a sheet of plywood. This DIY desk features a midcentury modern design with cubbies for storage space. If you love vintage furniture, you will love this desk!

I love simple builds, like this easy to build daybed, kitchen table and this bench. You might also like this simple table tutorial.

This easy to make desk is inspired by a vintage desk that I sold, much to my son’s chagrin. Luckily for him, I made him one that is (almost) just as cool.

It’s a tale as old as time. The shoemaker’s kids with no shoes. The furniture flipper’s kid with no desk. It just ain’t right. Particularly when said kid fell in love with a recent desk that I brought home and I sold it anyways.

Some moms are so mean.

In my defense, the desk he loved was far too large for his tiny room. I was very inspired by the MCM beauty and drew up plans to build him a simple version of that gorgeous desk.

Prep Work: Cutting and Painting the Wood

You can either get the nice people at the hardware store to cut your wood or you can cut it yourself at home. We chose to cut it ourselves at home since there were so many cuts. Note: if you don’t have a table saw, it’s still possible to cut your wood with a circular saw and a guide, which is how we do it.

Sand the edges to avoid splinters.

Separate your wood into cubby parts. I wanted the cubbies on the desk to be painted, so I primed the wood first. Each cubby is a different color, so I painted the pieces for the long skinny one in a dark navy (Clark and Kensington Nein Nein Nein – it’s a few years old) and the smaller cubby in my favorite shade of oops paint. It’s very similar to the Annie Sloan Amsterdam Green color though.

Once they were dry, I added pocket holes with a kreg jig to the top of the sides for the small cubby.

Building the Desk Cubbies

Now it’s time to assemble. Apply a thin line of glue along the back of the bottom piece.

Add the back to the desk and use corner clamps to line it up well. Use more clamps if necessary. Wipe away excess glue. 

Once clamped, attach the desk with the pneumatic nail gun.

I created the smaller cubby at the same time using the same steps of gluing and nailing the back to the bottom piece.

Let the glue dry for at least 30 minutes before removing the clamps.

Attach the sides in the same way for each cubby, but nail from the sides as well. Make sure that the pocket holes in the small cubby face up. 

Attach the desk top to the sides and back in the same manner. (The small cubby will not have a top.)

When everything is dry, add the plywood edging. It’s really easy to use and hides the plywood edges to make it look like a solid piece of wood. I found it easiest to roll it out to the right length and gently fold it at the edge where it needs to be cut to “mark” it. Then just cut it with scissors. Set the iron to “Cotton” (no steam) and just iron it in place, holding the iron in place for a few seconds until it stuck. You can use a towel or foil if you’re concerned about getting your iron dirty.

 Now it’s time to stain the outside of the desk. Normally, I like to use wood conditioner, but I forgot. Luckily the plywood stained beautifully without it! I used Minwax Dark Walnut, but Special Walnut would have been lovely as well. Stain the legs while you’re doing this.

Attaching the Desk Cubbies and Legs

I left the bottom unstained so that I could stain in once it was installed. Flip the piece to where the bottom is exposed and set the cubby on it upside down.

Attach the cubby with the pocket holes.

Find the center on the side of the desk and mark it with chalk if you stained it dark. Then line up the legs and screw them in place with deck screws. Deck screws really pull wood together nicely, so they’re my favorite to use. Plus, they’re harder to strip. 

Fill screw holes and pocket holes with wood filler if desired.

Touch up any stain that still needs to be stained.

Seal with a few coats of your favorite top coat. I used polycrylic applied with a sponge.

Flip over your desk and enjoy it.

I love the legs!

Now my kid has a simple desk of his own, just in time to start high school.

Two Weeks, 68 Failures, And One Perfect Run: A Rube Goldberg Story

Popular Science checked in with Doar throughout the build to gain some insight into his creative process. The project’s start was fairly simple. After sketching out his concept, Doar gathered his regular crew, including Trevor Yamamoto, T. J. Lewis, and Paul Thompson, and went shopping for materials. In this case, they relied mostly on wood, especially two-by-fours, which connected with the game’s rough-hewn, Old West look. “It has this tendency to look sophisticated but at the same time unsophisticated,” he says. “You can tell some skill has gone into building it, but it’s a little more accessible.”

Once he had his materials, Doar and his crew headed out to the set, an old, largely abandoned paint factory a few hours drive from Los Angeles. “I have a mobile shop that I bring, including a table saw, a chop saw, a band saw, a drill press, and more,” he says.

The initial construction took several days, but the real challenge was getting everything to work as well as it did in his head. Two days before the final video shoot, for example, Doar was struggling with one leg of the journey in particular, visible at the 53-second mark. “We’ve got one thing that is probably the most finicky,” he said at the time. “A sledgehammer drops and hits a teeter-totter and launches a ball up and banks it off a shovel and shoots it into a net.”

Sounds simple enough, right? The sequence would work perfectly, then fail, for no apparent reason. “I’m pretty sure we’re controlling every element, but every once in a while the ball completely misses, and I have no idea why. It might just be a question of humidity and temperature.”

Brett Doar And His Machine

Another tricky feat was the loop-the-loop, seen at the 1:00 mark. The ball–Leo–had to be moving fast enough to complete the circuit without falling, but if it gathered too much speed on the circular track, it would fly straight off the course. For Doar and his crew, that meant bending and re-bending pairs of quarter-inch steel rods until they formed the perfect circumference. After several trials, though, they managed to get it right.

Once the entire contraption was working, a second crew came in to dress up the set, and make it look more like the game, before the video shoot. That required additional tweaking on Doar’s part. For example, the set dressers stained some of the wood. “I figured staining would be fine,” he says. “But the stain caused some of the wood to swell.” That, in turn, changed the speed of the ball, so Doar and his crew worked late into the night before the final shoot, realigning the tracks, changing the angles to assure the ball would move at the proper pace.

After two weeks of work, and never quite figuring out why the ball was missing the net on occasion, Doar’s final obstacle was more mundane. In the closing shot, the rolling ball picks up a sticker with glasses and a moustache, so that he resembles Leo, the character in the game. “You need to figure out the endpoint so he’s looking directly into the camera,” Doar says. To get it right, they had to set the sticker in exactly the right spot, so that the ball would roll over it, pick up the tape, complete a 3/4 turn, then stop at the end of the track.

Yet it did end up functioning as they’d hoped, and all those little errors along the way were actually highlights of the experience. “Something always goes wrong,” Doar says. “You feel cheated if it doesn’t. If everything goes perfectly, you wonder, ‘Were we really pushing ourselves?’”

Google Pixelbook Go Review: One Chromebook To Rule Them All


Solid display

Decent performance

Great webcam


Chrome OS limitations

Expensive high-end models

Our Verdict

With a portable design, crisp display, quiet keyboard and all-day battery, the Pixelbook Go is a brilliant Chromebook option – though the higher-spec models are on the pricey side.

dGoogle released the Pixelbook Go back in 2023 as a successor to the Pixelbook, but with a much more affordable price tag. The word ‘Go’ in the name is certainly fitting – as this Chromebook has features that are perfect for anyone who needs a device that can be ported around with ease.

We spent some time with the Pixelbook Go to see if this Chromebook lives up to the hype – keep on reading for our thoughts in full. Alternatively, take a look at our guide to the best Chromebooks to see how rivals compare.

Design and build

At 1.06kg this is a featherweight device, and at only 11.4inch x 8.7inch, it can slip into most backpacks with ease. It’s perfect for students, as well as remote workers who use the Google ecosystem for most of their day-to-day tasks (such as the Tech Advisor team right now!).

The magnesium alloy body has a matt finish with curved edges. Whilst this does look polished, it picks up fingerprints quite easily, something to keep in mind if you’re bothered by this. We tested the ‘Just Black’ variant, but you can also get the Pixelbook in Google’s ‘Not Pink’ finish, although that’s only available on the 8GB/128GB version.

The bottom of the Pixelbook Go is ribbed to allow you to grip it more easily. Whether you like the bold appearance or not is a matter of preference, but as a self-confessed klutz, I was a big fan. It’s also comfortable to use and doesn’t feel strange in your lap. I did find on occasion that the Chromebook got a little on the hot side, though not to the point where it affected performance.

Both the top and bottom of the screen have quite large bezels that limit the display ever so slightly. Perhaps for future models, Google should look at maximising this space for a better viewing experience.

You also get a touchscreen with the Pixelbook. Personally, I didn’t find a lot of use for it – especially as this Chromebook can’t transform into a tablet option. However, if you enjoy design-based apps or the odd game that utilises touchscreen, you may find otherwise.

On the top of the screen, you get a 1080p webcam – almost unheard of on cheaper Chromebooks. The quality of the video is really decent, and the built-in microphone gives crisp audio quality. If you’re big on your video calls and conferences (who isn’t at the moment?), then the Pixelbook Go is definitely a good choice. Should you want to take a snap, then the camera has a resolution of 2Mp.

Ports wise, you only get two USB-C slots (this device uses USB-C charging) and a headphone jack. The lack of USB-A and HDMI means that the bottom half of the Chromebook is quite slim which is a plus, but just keep in mind that if you need these inputs you’ll need to purchase external adaptors.

Google’s keyboard features what they dub ‘Hush’ keys, and these certainly live up to the name. The keypress is ultra-quiet and extremely gentle on the bounce-back. Speakers are built into the sides of the keyboard, and this is actually a great location as it offers decent audio quality even if the laptop is resting on a surface.

Specs and performance

The Pixelbook Go we tested came with an Intel Core i5 processor, 8GB RAM and 128 GB storage, but there are three other models you can choose from.

The cheapest Pixelbook Go comes with Intel Core m3, 8GB RAM and 64 GB storage. For more space, you can either go for the Intel Core i5 version with 16GB RAM and 128 GB storage or the highest spec version which comes with Intel Core i7, 16GB RAM, 256 GB storage and a 4K screen (the other models only come in Full HD).

Whilst there is plenty of room for your various files, the integration into Google’s ecosystem means that most of your work will save on the cloud anyway, so you shouldn’t run out anytime soon.

The Go is extremely fast, even with numerous tabs open at one time. Obviously, it isn’t designed to run anything heavy-duty, but I was able to take on some basic photo editing whilst having other things running in the background with no issues whatsoever.

Despite the larger bezels that we mentioned earlier, the 13.3inch, 1080p screen with 16:9 ratio produces great colours and is bright enough to work with, even under direct sunlight. It’s great for streaming, as well as editing photos. The top-end Pixelbook offers a 4K screen, but the high price-tag and lack of ability to game make this feature seem a little redundant unless you expect to watch a lot of 4K videos.

Google promises up to 12 hours’ battery life from the 47Wh cell, and the Pixelbook Go almost lives up to the claim, lasting 10 hours and 53 minutes in our continuous video test. In real-time I managed to use it for a full working day, watching videos and listening to music at the same time without needing to run for my charger.

Charging times aren’t half bad either, with the device topping up to 28% in 30 minutes from empty. The battery life is one of the highlights of the Pixelbook Go, outperforming other rival Chromebooks.


There’s no denying that setting up the Pixelbook Go is a breeze. If you already have a Gmail account, then this process should take no longer than five minutes. All my work tabs were ready and waiting for me thanks to Google Drive, and instructions were easy to follow. Even the least tech-savvy people would be able to use this Chromebook straight out of the box.

The Pixelbook Go runs on Chrome OS, a lightweight system that runs most things through the browser. You can download apps from the Google Play Store – just like you would on an Android device – but the majority of these are web-based anyway. The overall impression is clean, minimalistic and easy-to-use.

The main tabs on the taskbar – Gmail, Google Docs and YouTube – open within a web browser window. Chrome OS works almost exactly the same as Google Chrome, and you can still access the Google features offline if you’re sans internet. You can also set up Google Assistant on the Pixelbook, both on your keyboard and via voice control.

Value for money

Most people who opt for Chromebooks forgo the capabilities of a laptop to save a few hundred quid. However, if you choose the highest spec Pixelbook Go, be prepared for it to be substantially pricier than most rivals.

There are a few different spec options, which at the time of writing cost:

Intel Core m3 8GB RAM 64 GB storage, Full HD screen – £629/$649

Intel Core i5 8GB RAM 128 GB storage, Full HD screen – £829/$849 (model we tested)

Intel Core i5 16GB RAM 128 GB storage, Full HD screen – £949/$999

Intel Core i7 16GB RAM 256 GB storage, 4K screen – £1,329/$1399

You can currently buy the Pixelbook Go from Google, John Lewis and Argos in the UK. In the US you can also get it from Google, as well as Best Buy.

Although this is a quick and responsive Chromebook, it’s worth keeping in mind that the two higher-end options cost around the same as numerous fully-fledged laptops such as the 2023 MacBook Air, which is a much more versatile device.

As for rival Chromebooks, the Asus Chromebook Flip C434TA comes with the same processor options and screen as the Pixelbook Go, but comes in a little cheaper, starting from £599. In general, most other Chromebooks that aren’t made by Google in our top ten list come in under £600. However, the Pixelbook merits that slight step up in price for its killer battery, simple OS and high-end design.


If you’re on the search for a Chromebook that’s easy to use, long-lasting and well-designed then you should absolutely consider the Pixelbook Go. It’s an all-rounder and outperforms other Chromebooks in numerous areas.

However, whilst the two cheaper variants are worth the investment, the higher-spec options are harder to justify. For that price, you could purchase a much higher-spec laptop running Windows or macOS. Plus, Chrome OS is mostly designed to save most of your work on the cloud anyway, so the extra storage space shouldn’t be a massive priority.

Nonetheless, there’s no denying that the Pixelbook Go should be at the top of your list for consideration if you’re on the search for a new Chromebook.
