Engineers who work for Elon Musk’s SpaceX have been brought on as senior advisers to the acting administrator of the Federal Aviation Administration (FAA), sources tell WIRED.

On Sunday, Sean Duffy, secretary of the Department of Transportation, which oversees the FAA, announced in a post on X that SpaceX engineers would be visiting the Air Traffic Control System Command Center in Virginia to take what he positioned as a tour. “The safety of air travel is a nonpartisan matter,” Musk replied. “SpaceX engineers will help make air travel safer.”

By the time these posts were made, though, according to sources who were granted anonymity because they fear retaliation, SpaceX engineers were already being onboarded at the agency under Schedule A, a special authority that allows government managers to “hire persons with disabilities without requiring them to compete for the job,” according to the Office of Personnel Management (OPM).

These new hires come after the terminations of hundreds of FAA probationary employees, and the most deadly month of US aviation disasters in more than a decade.

According to a source with knowledge of the situation, none of the SpaceX engineers were fully vetted by their start date. Unlike the very young technologists associated with Musk’s so-called Department of Government Efficiency (DOGE) who have been given access to critical systems at agencies ranging from OPM and the Treasury Department to the National Oceanic and Atmospheric Administration in recent weeks, though, the engineers identified by WIRED—Ted Malaska, Thomas Kiernan, Sam Smeal, and Brady Glantz—do appear to have experience relevant to the FAA.

Malaska is currently, according to his LinkedIn profile, a senior director of application software at SpaceX, where he started working in May 2021. Formerly the senior director of data engineering at Capitol One and a senior architect at FINRA, he graduated from the University of Maryland Baltimore County in 2000 and cowrote a 2015 book on Hadoop application architectures.

Kiernan is currently a lead software engineer at SpaceX, according to his LinkedIn page. Before joining SpaceX in May 2020, he worked at Wayfair and is a 2017 Dartmouth graduate.

Smeal is a software engineer who has worked at SpaceX since September 2021, according to his LinkedIn. He graduated from Saint Vincent College in 2018.

Glantz is a software engineer who has worked at SpaceX since May 2024 and worked as an engineering analyst at Goldman Sachs from 2019 to 2021, according to his LinkedIn, and graduated from the University of Michigan in 2019.

Malaska, Kiernan, Smeal, and Glantz did not immediately respond to requests for comment. The FAA also did not immediately respond to requests for comment.

In his post on X, Duffy wrote, "Because I know the media (and Hillary Clinton) will claim Elon’s team is getting special access, let me make clear that the @FAANews regularly gives tours of the command center to both media and companies.”

But on Wednesday, FAA acting administrator Chris Rocheleau wrote in an email to FAA staff, viewed by WIRED, that DOGE and the teams of special government employees deployed in federal agencies were “top-of-mind,” before noting that the agency had "recently welcomed” a team of special government employees who had already toured some FAA facilities. “We are asking for their help to engineer solutions while we keep the airspace open and safe,” he wrote, adding that the new employees had already visited the FAA Command Center and Potomac TRACON, a facility that controls the airspace around and provides air traffic control services to airports in the DC, Maryland, and Virginia areas.

In a Department of Transportation all-hands meeting late last week, Duffy responded to a question about DOGE's role in national airspace matters, and without explicitly mentioning the new employees, suggested help was needed on reforming Notice to Air Mission (NOTAM) alerts, a critical system that distributes real-time data and warnings to pilots but which has had significant outages, one as recently as this month. “If I can get ideas from really smart engineers on how we can fix it, I’m going to take those ideas,” he said, according to a recording of the meeting reviewed by WIRED. “Great engineers” might also work on airspace issues, he said.

SpaceX functioned as the pre-inauguration staging ground for the DOGE team, according to reporting from The New York Times and sources who spoke to WIRED. In the months between November 5 and January 20, members of DOGE including Steve Davis (president of Musk’s Boring Company) and the young engineer Luke Farritor were operating out of the company’s DC office, according to a source with knowledge.

The company did not respond to questions about whether these employees will retain their salaries and positions at the company during their time with DOGE. Many of the so-called department’s operatives have joined as “special government employees,” who are limited to working 130 days in a year. Last week WIRED reported that Tom Krause, a DOGE operative at the Treasury Department, would continue to maintain his position as CEO of the Cloud Software Group while also performing the duties of fiscal assistant secretary. Other members of Musk’s companies, including xAI and Tesla, have also taken on positions with DOGE.

Late last week, the Trump administration laid off 400 FAA workers, according to their union, the Professional Aviation Safety Specialists. The union says these included probationary employees who worked on air traffic control communications and related radio and computer systems. Air traffic controllers were not affected by the layoffs, Duffy said in an X post.

Just two weeks before that, the US suffered its most deadly aviation incident in more than a decade, when 67 people died after an Army helicopter collided with a passenger jet in Washington, DC. Though initial findings suggest complex equipment and communications issues possibly played roles in the disaster, President Trump was quick to blame “DEI,” railing against a decade-old program that helps the FAA identify talent among populations with disabilities. People with disabilities hired into the FAA and other federal agencies are often accepted under the Schedule A authority—exactly the route these new engineers have taken into the agency.

The FAA has frequently tangled with Musk’s SpaceX, as the rocket company and others fight to operate their own interests in crowded American airspace. In January, the FAA temporarily grounded SpaceX’s program after one of its Starship rockets broke apart midflight, reportedly damaging public property on Turks and Caicos in the Caribbean. The FAA diverted dozens of commercial airline flights following the explosion and announced an investigation into the incident, which is ongoing and being led by SpaceX. Musk, however, characterized the failure as “barely a bump in the road” and did not seem to indicate that the investigation would slow SpaceX’s launch cadence. Last year, the company indicated it was aiming for 25 launches of the Starship in 2025.

FAA spokesperson Steven Kulm told WIRED that “the FAA is overseeing the SpaceX-led mishap investigation.” The FAA did not respond to further questions about whether the presence of SpaceX engineers at the agency would constitute a conflict of interest.

In September, the FAA proposed $633,000 in fines following two 2023 incidents in which SpaceX allegedly did not follow its license requirements, violating regulations. Responding to an X user posting about the penalties, Musk wrote, “The fundamental problem is that humanity will forever be confined to Earth unless there is radical reform at the FAA!” Shortly afterward, Musk called for FAA head Mike Whitaker to resign.

In January, more than three years before his term was due to end, Whitaker did resign.

“I told Elon, any conflicts, you can’t have anything to do with that,” said President Trump in a press conference this week, in response to a question about Musk, SpaceX, the FAA, and conflicts of interest. “So anything to do with possibly even space, we won’t let Elon partake in that.”

The White House did not immediately respond to a request for comment.

SpaceX is directly regulated by a small FAA agency called the Office of Commercial Space Transportation, which since 1984 has licensed the launch of US space rockets. “The purpose is to ensure public safety,” says George Nield, a former associate administrator of the office. “People on the ground did not consent” to rocket launches above them, he says. ”We absolutely need to keep them safe. The office has done a great job of that.” The office oversaw 157 launches in 2024 alone.

On February 10, several days after Musk posted on X that DOGE “will aim to make rapid safety upgrades to the air traffic control system,” a group of Democratic legislators wrote to Rocheleau—a career civil servant whose ties to the FAA go back to 1996—requesting information about any planned changes to FAA systems.

“We are extremely concerned that an ad hoc team of individuals lacking any expertise, exposure, certifications, or knowledge of aviation operations being invited, or inserting themselves, to make ‘rapid’ changes to our nation’s air traffic systems,” they wrote. “Aviation safety is not an area to ‘move fast and break things.’”

Share Your Anecdotes: Multicore Pessimisation

I took a look at the specs of new 7000 series Threadripper CPUs, and I really don't have any excuse to buy one, even if I had the money to spare. I thought long and hard about different workloads, but nothing came to mind.

Back in university, we had courses about map/reduce clusters, and I experimented with parallel interpreters for Prolog, and distributed computing systems. What I learned is that the potential performance gains from better data structures and algorithms trump the performance gains from fancy hardware, and that there is more to be gained from using the GPU or from re-writing the performance-critical sections in C and making sure your data structures take up less memory than from multi-threaded code. Of course, all this is especially important when you are working in pure Python, because of the GIL.

The performance penalty of parallelisation hits even harder when you try to distribute your computation between different computers over the network, and the overhead of serialisation, communication, and scheduling work can easily exceed the gains of parallel computation, especially for small to medium workloads. If you benchmark your Hadoop cluster on a toy problem, you may well find that it's faster to solve your toy problem on one desktop PC than a whole cluster, because it's a toy problem, and the gains only kick in when your data set is too big to fit on a single computer.

The new Threadripper got me thinking: Has this happened to somebody with just a multicore CPU? Is there software that performs better with 2 cores than with just one, and better with 4 cores than with 2, but substantially worse with 64? It could happen! Deadlocks, livelocks, weird inter-process communication issues where you have one process per core and every one of the 64 processes communicates with the other 63 via pipes? There could be software that has a badly optimised main thread, or a badly optimised work unit scheduler, and the limiting factor is single-thread performance of that scheduler that needs to distribute and integrate work units for 64 threads, to the point where the worker threads are mostly idling and only one core is at 100%.

I am not trying to blame any programmer if this happens. Most likely such software was developed back when quad-core CPUs were a new thing, or even back when there were multi-CPU-socket mainboards, and the developer never imagined that one day there would be Threadrippers on the consumer market. Programs from back then, built for Windows XP, could still run on Windows 10 or 11.

In spite of all this, I suspect that this kind of problem is quite rare in practice. It requires software that spawns one thread or one process per core, but which is deoptimised for more cores, maybe written under the assumption that users have for two to six CPU cores, a user who can afford a Threadripper, and needs a Threadripper, and a workload where the problem is noticeable. You wouldn't get a Threadripper in the first place if it made your workflows slower, so that hypothetical user probably has one main workload that really benefits from the many cores, and another that doesn't.

So, has this happened to you? Dou you have a Threadripper at work? Do you work in bioinformatics or visual effects? Do you encode a lot of video? Do you know a guy who does? Do you own a Threadripper or an Ampere just for the hell of it? Or have you tried to build a Hadoop/Beowulf/OpenMP cluster, only to have your code run slower?

I would love to hear from you.

Choosing the Right CMS for Your Website

It probably goes without saying that when developing any kind of website, one of the most strategic actions you will be taking is determining which CMS to use. It can simply be described as an application that enables users who may not have extensive knowledge on coding to build, design and edit content on their website. Like any other professional web design service provider can explain, the selection of proper CMS for your site can greatly influence how doable or manageable your site is. 

Why Choosing the Right CMS matters 

Choosing the right CMS is really important as it decides on how your website operates and how convenient it is to administer. A good web design company appreciates the role of a good CMS that reduces costs and time required in maintaining a site. It can also influence your website performance and that is important for enhancing users satisfaction and also the position of your website on the search engines. 

Popular CMS Options 

WordPress 

Wordpress is one of the Content Management Systems that is on high demand in the modern Internet market. Currently, many website designing companies advise and encourage users to adopt the WordPress website since it is convenient. It is perfect for blogs and small businesses and useful for large websites. It has access to thousands of themes and plugins which will allow you to have the specific layout you require. 

Joomla 

The other CMS is Joomla and it is slightly complicated as compared to WordPress. It is suitable if one requires enhanced functionality and is okay with going through a complex learning curve. There are some website designing companies which prefer Joomla for the complex projects. 

Drupal 

Some of the benefits of using Drupal include; it has strong security measures and is known to support large and complicated websites. Still, Hadoop is mostly employed in governmental bodies together with huge-scale businesses. Despite the fact that relatively more programming skills are needed, many web site designing companies use Drupal for those clients who have particular security requirements or who have a complex structure of their web site. 

Factors to talk about when Identifying the CMS. 

Ease of Use 

Where does or do you/your team stand in terms of your comfort level with technology? When you use CSM platforms, they vary depending on how friendly they are to the users. When it comes to selecting the right CMS, a good website designing company will guide you to the selection of the right CMS that you have adequate skills in using. 

Scalability 

Consider what your needs are going to be in the future. Will your website have a great expansion? But not all the CMS platforms manage growth in the same way. When choosing the best CMS for your business, your website designing company needs to factor in your vision in future. 

Customization Options 

If you want your website to be completely distinctive, then this is how you can achieve that. Depending on the specific CMS being used there can be quite a large variation between the amount of control each platform allows. Explain your design requirements to the website designing company so that the choice of CMS will effectively meet your requirements for the design. 

Support and Community 

Ensure that the chosen CMS has a good support system and a good customer base. This can be extremely beneficial when needing support and or to include more functionalities to your page. An experienced web designing company can help you in identifying the available cms platforms with better support systems. 

Making Your Decision 

Selecting the right CMS can be quite a significant decision and that you don’t have to make on your own. Often it might be prudent to consult a professional website designing company that can consider your needs, budget and technical capacities to suggest you the most appropriate CMS for the undertaking in question. They can also assist you to choose your ideal CMS and implement it with the specific aim and appearance of your website in mind. 

Just be advised that there are no two identical CMS platforms and there is nothing which fits all. Sometimes the strategies that a particular website uses will not be as effective for another website. Be patient and do not rush into enrolling in any college without consulting and gather as much information as you can. Therefore by choosing the right CMS and working with a good website designing company you will be on the right path as far as establishing and managing a successful website is concerned.

What are the benefits of Amazon EMR? Drawbacks of AWS EMR

Benefits of Amazon EMR

Amazon EMR has many benefits. These include AWS's flexibility and cost savings over on-premises resource development.

Cost-saving

Amazon EMR costs depend on instance type, number of Amazon EC2 instances, and cluster launch area. On-demand pricing is low, but Reserved or Spot Instances save much more. Spot instances can save up to a tenth of on-demand costs.

Note

Using Amazon S3, Kinesis, or DynamoDB with your EMR cluster incurs expenses irrespective of Amazon EMR usage.

Note

Set up Amazon S3 VPC endpoints when creating an Amazon EMR cluster in a private subnet. If your EMR cluster is on a private subnet without Amazon S3 VPC endpoints, you will be charged extra for S3 traffic NAT gates.

AWS integration

Amazon EMR integrates with other AWS services for cluster networking, storage, security, and more. The following list shows many examples of this integration:

Use Amazon EC2 for cluster nodes.

Amazon VPC creates the virtual network where your instances start.

Amazon S3 input/output data storage

Set alarms and monitor cluster performance with Amazon CloudWatch.

AWS IAM permissions setting

Audit service requests with AWS CloudTrail.

Cluster scheduling and launch with AWS Data Pipeline

AWS Lake Formation searches, categorises, and secures Amazon S3 data lakes.

Its deployment

The EC2 instances in your EMR cluster do the tasks you designate. When you launch your cluster, Amazon EMR configures instances using Spark or Apache Hadoop. Choose the instance size and type that best suits your cluster's processing needs: streaming data, low-latency queries, batch processing, or big data storage.

Amazon EMR cluster software setup has many options. For example, an Amazon EMR version can be loaded with Hive, Pig, Spark, and flexible frameworks like Hadoop. Installing a MapR distribution is another alternative. Since Amazon EMR runs on Amazon Linux, you can manually install software on your cluster using yum or the source code.

Flexibility and scalability

Amazon EMR lets you scale your cluster as your computing needs vary. Resizing your cluster lets you add instances during peak workloads and remove them to cut costs.

Amazon EMR supports multiple instance groups. This lets you employ Spot Instances in one group to perform jobs faster and cheaper and On-Demand Instances in another for guaranteed processing power. Multiple Spot Instance types might be mixed to take advantage of a better price.

Amazon EMR lets you use several file systems for input, output, and intermediate data. HDFS on your cluster's primary and core nodes can handle data you don't need to store beyond its lifecycle.

Amazon S3 can be used as a data layer for EMR File System applications to decouple computation and storage and store data outside of your cluster's lifespan. EMRFS lets you scale up or down to meet storage and processing needs independently. Amazon S3 lets you adjust storage and cluster size to meet growing processing needs.

Reliability

Amazon EMR monitors cluster nodes and shuts down and replaces instances as needed.

Amazon EMR lets you configure automated or manual cluster termination. Automatic cluster termination occurs after all procedures are complete. Transitory cluster. After processing, you can set up the cluster to continue running so you can manually stop it. You can also construct a cluster, use the installed apps, and manually terminate it. These clusters are “long-running clusters.”

Termination prevention can prevent processing errors from terminating cluster instances. With termination protection, you can retrieve data from instances before termination. Whether you activate your cluster by console, CLI, or API changes these features' default settings.

Security

Amazon EMR uses Amazon EC2 key pairs, IAM, and VPC to safeguard data and clusters.

IAM

Amazon EMR uses IAM for permissions. Person or group permissions are set by IAM policies. Users and groups can access resources and activities through policies.

The Amazon EMR service uses IAM roles, while instances use the EC2 instance profile. These roles allow the service and instances to access other AWS services for you. Amazon EMR and EC2 instance profiles have default roles. By default, roles use AWS managed policies generated when you launch an EMR cluster from the console and select default permissions. Additionally, the AWS CLI may construct default IAM roles. Custom service and instance profile roles can be created to govern rights outside of AWS.

Security groups

Amazon EMR employs security groups to control EC2 instance traffic. Amazon EMR shares a security group for your primary instance and core/task instances when your cluster is deployed. Amazon EMR creates security group rules to ensure cluster instance communication. Extra security groups can be added to your primary and core/task instances for more advanced restrictions.

Encryption

Amazon EMR enables optional server-side and client-side encryption using EMRFS to protect Amazon S3 data. After submission, Amazon S3 encrypts data server-side.

The EMRFS client on your EMR cluster encrypts and decrypts client-side encryption. AWS KMS or your key management system can handle client-side encryption root keys.

Amazon VPC

Amazon EMR launches clusters in Amazon VPCs. VPCs in AWS allow you to manage sophisticated network settings and access functionalities.

AWS CloudTrail

Amazon EMR and CloudTrail record AWS account requests. This data shows who accesses your cluster, when, and from what IP.

Amazon EC2 key pairs

A secure link between the primary node and your remote computer lets you monitor and communicate with your cluster. SSH or Kerberos can authenticate this connection. SSH requires an Amazon EC2 key pair.

Monitoring

Debug cluster issues like faults or failures utilising log files and Amazon EMR management interfaces. Amazon EMR can archive log files on Amazon S3 to save records and solve problems after your cluster ends. The Amazon EMR UI also has a task, job, and step-specific debugging tool for log files.

Amazon EMR connects to CloudWatch for cluster and job performance monitoring. Alarms can be set based on cluster idle state and storage use %.

Management interfaces

There are numerous Amazon EMR access methods:

The console provides a graphical interface for cluster launch and management. You may examine, debug, terminate, and describe clusters to launch via online forms. Amazon EMR is easiest to use via the console, requiring no scripting.

Installing the AWS Command Line Interface (AWS CLI) on your computer lets you connect to Amazon EMR and manage clusters. The broad AWS CLI includes Amazon EMR-specific commands. You can automate cluster administration and initialisation with scripts. If you prefer command line operations, utilise the AWS CLI.

SDK allows cluster creation and management for Amazon EMR calls. They enable cluster formation and management automation systems. This SDK is best for customising Amazon EMR. Amazon EMR supports Go, Java,.NET (C# and VB.NET), Node.js, PHP, Python, and Ruby SDKs.

A Web Service API lets you call a web service using JSON. A custom SDK that calls Amazon EMR is best done utilising the API.

Complexity:

EMR cluster setup and maintenance are more involved than with AWS Glue and require framework knowledge.

Learning curve

Setting up and optimising EMR clusters may require adjusting settings and parameters.

Possible Performance Issues:

Incorrect instance types or under-provisioned clusters might slow task execution and other performance.

Depends on AWS:

Due to its deep interaction with AWS infrastructure, EMR is less portable than on-premise solutions despite cloud flexibility.
