Tesla CEO Elon Musk gave the strongest hint yet Monday that he would like to pay less for Twitter than his $44 billion offer made last month. Musk told a Miami technology conference that a viable deal at a lower price would not be out of the question, according to a report by Bloomberg News, which said it viewed a livestream video of the conference posted by a Twitter user. Also at the All In Summit, Musk estimated that at least 20% of Twitter's 229 million accounts are spam bots, percentage he said was at the low end of his assessment, according to the report. The appearance came a few hours after Musk began trolling Twitter CEO Paraj Agrawal, who posted a series of tweets explaining his company's effort to fight bots and how it has consistently estimated that less than 5% of Twitter accounts are fake. Also read: Elon Musk says Twitter deal ‘temporarily on hold’ In all, the day's events bolstered theories from analysts that Musk either wants out of the deal or is seeking a lower price, largely due to a huge decline in value of Tesla stock, some of which he has pledged to finance the Twitter acquisition. Twitter shares closed Monday down just over 8% at $37.39, below where the stock was just before Musk disclosed that he was Twitter's largest shareholder. Musk made the offer to buy Twitter for $54.20 per share on April 14. On Friday Musk tweeted that his plan to buy Twitter was placed on temporary hold as he tried to pinpoint the number of fake accounts on the social media platform. The Tesla and SpaceX CEO said the hold was pending details of Twitter's calculation that fake accounts are less than 5% of its users. In tweets on Monday, Agrawal acknowledged Twitter isn't perfect at catching spam. He wrote that every quarter, the company has made the estimate of less than 5% spam. “Our estimate is based on multiple human reviews of thousands of accounts that are sampled at random, consistently over time,” Agrawal wrote. Estimates for the last four quarters were all well under 5%, he wrote. “The error margins on our estimates give us confidence in our public statements each quarter.” Musk, using his favorite platform, responded with a smiling emoji of poop, then asked how Twitter's advertisers know what they're getting for their money. Tesla shares closed Monday down nearly 6% at $724.37. They have lost about one-third of their value since the trading day before Musk disclosed his Twitter stake.

When you need a computer, you should always get a new laptop or Desktop PC. However, there may be occasions in which this is not possible, and you will have to settle with a previously owned item. Unfortunately, purchasing a used computer is never a simple process. Ultimately, you must ensure that you are not being defrauded by an unscrupulous merchant. There are a number of factors to consider before purchasing a used laptop or Desktop PC. Thus, you may confirm that you are receiving the device you paid for. Risks in Buying a Secondhand Laptop To play high-end games or do professional 3D drafting, a second hand PC may not be your best option. Graphics processors continue to advance more rapidly than other computer components, and the upcoming release of new game consoles in the autumn will result in greater system requirements for PC games. However, a second hand laptop may still be suitable for picture and video editing since these applications do not need as much graphics capability. A secondhand laptop often does not include top-tier customer service or warranty coverage, such as that provided by an AppleCare Protection Plan or an extended manufacturer warranty. There are second hand PCs available with one or two years remaining on their original warranties, and these warranties often transfer to new owners without issue. However, it is more typical to discover 30- or 90-day limited warranties that protect you if the computer is defective upon delivery but not much more. Read Best Laptops for Graphic Designers in Bangladesh in 2022 Things to Check while buying a used laptop or computer Secure Yourself Laptops vary widely in price, but it's safe to assume that they are not inexpensive pieces of technology. When making a purchase for a substantial amount of money, you want to know that you have some kind of protection. In this regard, large sites like eBay and Amazon are often safe bets. The protection provisions of eBay tend to favour the buyer, so if the laptop is in worse condition than you anticipated (or does not function), the seller must accept a return at their cost. When purchasing a laptop from a website like Craigslist or Gumtree, the easiest method to protect yourself is to organise a pick up and examine the laptop personally. If you are really unable to do so, you should attempt to pay using PayPal, which provides comparable buyer protections to eBay. Read Business Laptop Buyer Guide with Price Ranges in Bangladesh Signs of Damage When purchasing a vehicle or a computer, it is prudent to inspect both the inside and outside. The state of the computer is an indicator of whether or not it is a good purchase. PCs include fragile electrical components. You should not purchase an item that has been through difficult circumstances. You should be on the lookout for dents and deep scrapes as indicators of neglect. Additionally, you should look out for water damage. A discoloured casing or rust indicates that it may have been soaked or dipped in liquid. Physical damage is not always a red sign, particularly if the equipment has been properly fixed, but it provides you negotiating room. Check the Accessories When purchasing a desktop computer, is a monitor included? Is the display still operating normally? Does it create the correct colour still? Be sure to inspect all of the peripherals that came with your purchase so that you do not have to deal with damaged components or pay additional money to repair them.

No matter how intelligent your phone is, it cannot swim. During outdoor water activities or rain, your adorable Smartphone might get wet. Sometimes phones fall into water accidentally while you are staying indoors. So, what is the best approach to prevent water damage to your phone? Experts advise purchasing a floating, waterproof phone case. But not all budget and mid-range phones offer such features. So what to do when your phone falls into the water? Here are some vital suggestions. How Can a Phone Get Damaged After Falling into Water? When water enters the ports, jacks, and speakers of a mobile device, it becomes its kryptonite. After entering, the fluid flows into the circuits. The outcome? The water, which functions as a conductor, transmits a current that overloads the phone's circuit board with energy. This is exacerbated by some behaviours, such as letting the phone dry on its own. Due to the minerals in the water, letting water sit in the phone causes corrosion of its circuits, coils, and resistors. Read: Infinix Note 12 Review: Is it worth buying? This one also confuses people since the harm is not often immediately obvious. Occasionally, it may take a bit longer for water to reach sensitive components. Because of this, a phone may be dropped in the water without suffering any obvious damage. The next day, though, those unfortunate folks will be unable to switch on their phones. The other factor to consider is the water supply. If you put your phone in a puddle or the toilet, it will survive, but if you dump it in the ocean, you can say goodbye to it. Saltwater is very corrosive and will harm the components of a phone far more quickly than freshwater. Therefore, use caution while snapping selfies on your boat. Tips to Fix a Water-Damaged Smartphone Be proactive You may wish to get a waterproof phone with a high IP rating to ensure that it can withstand a plunge. However, not all of us will have access to water-resistant smartphones. If your phone cannot take liquids and you know you will be putting it at risk on your next beach vacation, it may be worthwhile to invest in a waterproof phone bag. Read Freezer, Fridge, Refrigerator Explosion: Causes, Risks Factors, Ways of Prevention Turn It Off As Soon As Possible It is difficult to respond swiftly after such a catastrophic occurrence, but you must! The longer your gadget is submerged, the less likely it is to survive. You must immediately excavate the area and get the phone from the water. Yes, even if it's in the restroom! Upon removing the phone from the water, ensure that it remains off. Even if everything seems OK, it is essential to turn it off just in case. If the phone is still active, just turn it off.   Turning off the smartphone prevents water from reaching and damaging vital phone components while electronics are operating. Water that reaches operational components is more likely to inflict irreparable harm. Read Power Bank Buyer guide with Price Ranges in Bangladesh
