Grouping Data by Time Intervals in SQL Server: Hourly and 10-Minute Aggregations
In SQL Server, grouping data by time intervals such as by hour or by 10 minutes requires manipulation of the date and time values so that rows falling within each interval are grouped together. This can be achieved using the DATEPART function for hourly grouping or a combination of DATEPART and arithmetic operations for more granular groupings like every 10 minutes. Here’s how you can do…

My Experience with Database Homework Help from DatabaseHomeworkHelp.com
As a student majoring in computer science, managing the workload can be daunting. One of the most challenging aspects of my coursework has been database management. Understanding the intricacies of SQL, ER diagrams, normalization, and other database concepts often left me overwhelmed. That was until I discovered Database Homework Help from DatabaseHomeworkHelp.com. This service has been a lifesaver, providing me with the support and guidance I needed to excel in my studies.
The Initial Struggle
When I first started my database course, I underestimated the complexity of the subject. I thought it would be as straightforward as other programming courses I had taken. However, as the semester progressed, I found myself struggling with assignments and projects. My grades were slipping, and my confidence was waning. I knew I needed help, but I wasn't sure where to turn.
I tried getting assistance from my professors during office hours, but with so many students needing help, the time available was limited. Study groups with classmates were somewhat helpful, but they often turned into social gatherings rather than focused study sessions. I needed a more reliable and structured form of support.
Discovering DatabaseHomeworkHelp.com
One evening, while frantically searching for online resources to understand an especially tricky ER diagram assignment, I stumbled upon DatabaseHomeworkHelp.com. The website promised expert help on a wide range of database topics, from basic queries to advanced database design and implementation. Skeptical but hopeful, I decided to give it a try. It turned out to be one of the best decisions I’ve made in my academic career.
First Impressions
The first thing that struck me about DatabaseHomeworkHelp.com was the user-friendly interface. The website was easy to navigate, and I quickly found the section where I could submit my assignment. The process was straightforward: I filled out a form detailing my assignment requirements, attached the relevant files, and specified the deadline.
Within a few hours, I received a response from one of their database experts. The communication was professional and reassuring. They asked a few clarifying questions to ensure they fully understood my needs, which gave me confidence that I was in good hands.
The Quality of Help
What impressed me the most was the quality of the assistance I received. The expert assigned to my task not only completed the assignment perfectly but also provided a detailed explanation of the solutions. This was incredibly helpful because it allowed me to understand the concepts rather than just submitting the work.
For example, in one of my assignments, I had to design a complex database schema. The expert not only provided a well-structured schema but also explained the reasoning behind each table and relationship. This level of detail helped me grasp the fundamental principles of database design, something I had been struggling with for weeks.
Learning and Improvement
With each assignment I submitted, I noticed a significant improvement in my understanding of database concepts. The experts at DatabaseHomeworkHelp.com were not just solving problems for me; they were teaching me how to solve them myself. They broke down complex topics into manageable parts and provided clear, concise explanations.
I particularly appreciated their help with SQL queries. Writing efficient and effective SQL queries was one of the areas I found most challenging. The expert guidance I received helped me understand how to approach query writing logically. They showed me how to optimize queries for better performance and how to avoid common pitfalls.
Timely Delivery
Another aspect that stood out was their commitment to deadlines. As a student, timely submission of assignments is crucial. DatabaseHomeworkHelp.com always delivered my assignments well before the deadline, giving me ample time to review the work and ask any follow-up questions. This reliability was a significant relief, especially during times when I had multiple assignments due simultaneously.
Customer Support
The customer support team at DatabaseHomeworkHelp.com deserves a special mention. They were available 24/7, and I never had to wait long for a response. Whether I had a question about the pricing, needed to clarify the assignment details, or required an update on the progress, the support team was always there to assist me promptly and courteously.
Affordable and Worth Every Penny
As a student, budget is always a concern. I was worried that professional homework help would be prohibitively expensive. However, I found the pricing at DatabaseHomeworkHelp.com to be reasonable and affordable. They offer different pricing plans based on the complexity and urgency of the assignment, making it accessible for students with varying budgets.
Moreover, considering the quality of help I received and the improvement in my grades, I can confidently say that their service is worth every penny. The value I got from their expert assistance far outweighed the cost.
A Lasting Impact
Thanks to DatabaseHomeworkHelp.com, my grades in the database course improved significantly. But beyond the grades, the most valuable takeaway has been the knowledge and confidence I gained. I now approach database assignments with a clearer understanding and a more structured method. This confidence has also positively impacted other areas of my studies, as I am less stressed and more organized.
Final Thoughts
If you're a student struggling with database management assignments, I highly recommend Database Homework Help from DatabaseHomeworkHelp.com. Their expert guidance, timely delivery, and excellent customer support can make a significant difference in your academic journey. They don’t just provide answers; they help you understand the material, which is crucial for long-term success.
In conclusion, my experience with DatabaseHomeworkHelp.com has been overwhelmingly positive. The support I received has not only helped me improve my grades but also enhanced my overall understanding of database concepts. I am grateful for their assistance and will undoubtedly continue to use their services as I progress through my computer science degree.

This SQL Trick Cut My Query Time by 80%
How One Simple Change Supercharged My Database Performance
If you work with SQL, you’ve probably spent hours trying to optimize slow-running queries — tweaking joins, rewriting subqueries, or even questioning your career choices. I’ve been there. But recently, I discovered a deceptively simple trick that cut my query time by 80%, and I wish I had known it sooner.
Tumblr media
Here’s the full breakdown of the trick, how it works, and how you can apply it right now.
🧠 The Problem: Slow Query in a Large Dataset
I was working with a PostgreSQL database containing millions of records. The goal was to generate monthly reports from a transactions table joined with users and products. My query took over 35 seconds to return, and performance got worse as the data grew.
Here’s a simplified version of the original query:
sql
SELECT
u.user_id,
SUM(t.amount) AS total_spent
FROM
transactions t
JOIN
users u ON t.user_id = u.user_id
WHERE
t.created_at >= '2024-01-01'
AND t.created_at < '2024-02-01'
GROUP BY
u.user_id, http://u.name;
No complex logic. But still painfully slow.
⚡ The Trick: Use a CTE to Pre-Filter Before the Join
The major inefficiency here? The join was happening before the filtering. Even though we were only interested in one month’s data, the database had to scan and join millions of rows first — then apply the WHERE clause.
✅ Solution: Filter early using a CTE (Common Table Expression)
Here’s the optimized version:
sql
WITH filtered_transactions AS (
SELECT *
FROM transactions
WHERE created_at >= '2024-01-01'
AND created_at < '2024-02-01'
)
SELECT
u.user_id,
SUM(t.amount) AS total_spent
FROM
filtered_transactions t
JOIN
users u ON t.user_id = u.user_id
GROUP BY
u.user_id, http://u.name;
Result: Query time dropped from 35 seconds to just 7 seconds.
That’s an 80% improvement — with no hardware changes or indexing.
🧩 Why This Works
Databases (especially PostgreSQL and MySQL) optimize join order internally, but sometimes they fail to push filters deep into the query plan.
By isolating the filtered dataset before the join, you:
Reduce the number of rows being joined
Shrink the working memory needed for the query
Speed up sorting, grouping, and aggregation
This technique is especially effective when:
You’re working with time-series data
Joins involve large or denormalized tables
Filters eliminate a large portion of rows
🔍 Bonus Optimization: Add Indexes on Filtered Columns
To make this trick even more effective, add an index on created_at in the transactions table:
sql
CREATE INDEX idx_transactions_created_at ON transactions(created_at);
This allows the database to quickly locate rows for the date range, making the CTE filter lightning-fast.
🛠 When Not to Use This
While this trick is powerful, it’s not always ideal. Avoid it when:
Your filter is trivial (e.g., matches 99% of rows)
The CTE becomes more complex than the base query
Your database’s planner is already optimizing joins well (check the EXPLAIN plan)
🧾 Final Takeaway
You don’t need exotic query tuning or complex indexing strategies to speed up SQL performance. Sometimes, just changing the order of operations — like filtering before joining — is enough to make your query fly.
“Think like the database. The less work you give it, the faster it moves.”
If your SQL queries are running slow, try this CTE filtering trick before diving into advanced optimization. It might just save your day — or your job.

State Wars Hacked, Ends 3 Days Early, Prompts Strike & Ban Wave
By LittleMissRachie | April 26 2025
Overnight US time during day 3 of State Wars: Pretty in Pink, a 24-hour old account without citizenship had accumulated and spent two million State Wars points. The hacker appears to have had admin level access, as the account was able to continue "earning" and spending points from jail, and further, from a banned account, signalling for many issues with Ximboland's security forces and infrastructural durability in times of strife.
On Easter Sunday, April 20th, by 10:30PM players noticed something awry. As early as 9pm, and within 24 hours of the account’s creation, user nullplayer, supposedly a Secvillian, had reached level 21 and somehow accumulated more than two hundred seventy thousand State Wars points. By 9:35, almost half a million points and level 29. At first, state groups were thankful this hacker hadn’t spent those points. They had spoken too soon. Soon after, this account direct spent all its points and exploited a win for Seville, which was in last place.
Answers? And a gripe with management
At 3:16 Ximboland time, user notnullplayer, claiming to be the hacker, brigaded every recent topic in the forum with a reply linking to a topic: Nullplayer’s Guide to Breaking Ximboland’s Security (and Free Diamonds for All). This post maligns Ximboland’s lack of rate limits, hence the mass-posting, likely with a script according to their posts, first to the state town halls and then in reply to all of the top threads in the forums, totalling 13 pages of posts on the profile. The post goes on to outline explicitly the tools used to exploit the website, and as a result, will not be linked to, quoted in its entirety here, nor available to view. To be taken with a grain of salt, the purported hacker’s Q&A is outlined below, in response to questions posed by user kimjongin:
Was[sic] the security breach been contained?
No, it wasn’t. It's been over a day and I haven’t seen a single line of code changed. Hopefully this post puts some pressure on the admins to actually do something.
Is our data safe?
Kind of — but not entirely. Passwords are encrypted, sure, but if an attacker gets access, they’re still vulnerable. And yes, SQL injection is still possible in this game.
(Don’t worry about payments - if I wanted money, I'd just threaten the admins. Way easier.)
Are our private outfits protected?
No. I'm determined enough to prove there’s a flaw, but not unemployed enough to actually write a script for a mass outfit change (but I could).
Interestingly, notnullplayer adds a final and personal jab at the outgoing Minister of Justice, KatieBoutique, who rallied multistate support against the hacked end to State Wars. KatieBoutique is a Reasonopian, who shared the lead with Freethinkerland and Agnostica early in the Pretty and Pink War, and was understandably enraged by the exploitation of State Wars.
Is Katie/Kate (whatever) a bitch?
Yes. Painfully so. She’s living proof of poor management — like it wasn’t obvious already.
This arguably signals that the hacker may be more familiar with Ximboland than they claim.
They outline the exploits used in what sounds like an older version of Ximboland; “Back then, I noticed some pretty serious security issues in the game. It seems to me that admins were aware, but didn’t do anything to fix them.” According to the post, “One major flaw let me inject JavaScript into fields like bios and signatures, which means anyone who viewed my profile or forum signature would unknowingly run scripts in their browser.”
The hacker claims “the game relies heavily on JavaScript for its client-side functionality,” and that as a result, “this kind of vulnerability could’ve let me silently steal sessions (including admin accounts) or perform actions as if I were them (like banning players without needing admin access, directly from their accounts, without any logs).” Simply put, the hacker could have run programs on user computers, through their bio or signature on a post in the forums. By viewing the post or profile without even the need to click a link, this hacker could allegedly access the outfits and profiles of users, even potentially changing user passwords. notnullplayer goes on, “just by posting on the forum, I could’ve gained full control over all accounts who saw my posts or visited my profile.”
According to Minister of Entertainment Tibby, the attack was an SQL injection, and that they did in fact have an active script in their signature at one point. “inspecting nullplayer's signature, it seems they turned the script off, for now” and speculates that this “is also why some people were and some people werent impacted,” and that “only those who looked at the posts while the script was on were vulnerable to those specific attacks.” A comment reply stands out from user replytotibby, claiming that not to be the case. The self proclaimed hacker purported that while the website is vulnerable to these kind of SQL attacks, even now, that was not what the destruction of outfits was.
“I didn't use any of them. The javascript thing I told about on the post was fixed back then, years ago, just as I said I didn't make any posts with javascript on the signature. I clearly said SQL injections are possible, but I never used it. I also wouldn't need any player to do anything if I was to use it. I didn't spoof anything as well, pretending to be on other players' account. I just directly saved them from the API.”
Outfits were directly manipulated, turned into the silhouette featured for private outfit thumbnails, and the unsettling default Ximbo outfit featuring sunglasses and a black and yellow ensemble. The outfits of high profile figures in State Wars and the leaderboards, as well as Pink House officials, were targeted. The author of this article reached out to the yet-to-be-jailed account replytotibby, which had outlined the tools they used to hack the website in the Xeet replies to Minister of Entertainment Tibby, and was able to secure the answers to a few questions. Granted, these responses are in the words of the self-proclaimed hacker themselves, and are to be read with healthy skepticism. The interview is below, and is copy and pasted in its entirety, typos and all.
Interview with replytotibby
What were your intentions in hacking the site? What message do you want to send?
 Not really much, I just want those problems fixed. As I said on the post, besides the fun of it (coding bots, wrecking havoc, causing chaos and seeing people's
reactions), I dislike irresponsible admins and lazy devs.
Why destroy peoples’ outfits?
I just wanted to show it's possible. Just messing with the war rankings seems too bland.
How did you choose whose outfits would be nullified?
I chose the most active ones, the ones who apparently were online the most, xeeting and participating on events. It seems to me that there is a specific group of players who know each others well and play a lot. And Katie because she's a disgrace to management. I used to be an admin for other games and website communities too, and I was proud of what I did. She just seems to want control over people. I also focused on people who annoyed me slightly or were really focused on the whole situation, as well as went completely random on some people, or used them to re-test the script.
What made you choose state war as a specific event to hijack?
I didn't hehe but I saw the chance for some fun on it because it seemed like a major event.
How do you know Katie? You referenced her personally.
After hacking I kept checking the website for the admins' reaction and players' as well, which is where most of the fun lies.
When did you first play Ximboland, and how would you describe the state of site safety then?
I can't tell when I first played becuase that could, maybe, tell on me, but it has passed some years since then. Site safety was the same as now - exactly the same, nothing changed. New games, however, do seem a bit safer than old ones (or I just don't know sliding puzzle works and don't have the patience to try)
Unfortunately the user doesn’t go into detail on their history with the site, leaving investigators with few clues into their identity. They claim the attack isn’t driven by personal vengeance, but little is known of their relationship to Ximboland.
The response
This and the provided javascript signals that anyone could gain access to player outfits, forum functionality and other functions like State Wars. What remained unknown for more than a week is the full extent of the vulnerability in 2025. SweetasNuts had not commented on the specific vulnerabilities of the site, nor had admin Mariolka and Sachem, until 6 days later, the 26th.
After the popular jailing of nullplayer, citizens were widely in support of Minister KatieBoutique, commenting widely in thanks for doing what she could to stop the hacker with the tools available to the Ministry of Justice. Replies to MoJ’s Xeets on the 20th are rife with comments like “Thank you Katie! ❤️” from user TokiKonoe, “rare katie W” from user alexa pro, and other cheers for the chief of the Fashion police.
The first official response came from Prime Ximbo and reigning autocrat SweetasNuts on the 21st, a post titled Ximboland is under attack. In it, the Prime Ximbo is vague about the attack, providing information whose relevance is argued in the replies: “Preliminary reports from the Minister of defence suggest that this was an act of treason from someone whom knows about Ximboland from within rather than an act of war from a foreign land. It goes without saying that when we catch the traitor then their punishment for this will be the complete deportation from Ximboland into permanent exile and we will notify the relevant legal authorities of their new homeland for illegally hacking into a private property. Justice will be served.”
The post provided no information about how the hack was possible, or what steps were being taken to secure the site. But the autocrat was quick to assuage nerves about the security of payment information. “A reminder that we store ZERO banking information in Ximboland so there is no information that you share with us that could be valuable to hostile foes like the idiot killjoy who did this. We use a 3rd party payment provider (paypal) exactly for this reason ie we have nothing of particular value to anyone. So please dont worry.” This comes despite the fact that PayPal authorizations may very well be vulnerable as well.
With no direction for Pink House officials or guidance on what game features were safe, confusion and uncertainty loomed, on the 21st, chaos continued to spread. The outgoing Minister of Justice, with less than two weeks remaining in their term, Xeeted plans for jailings, on the grounds that “The leftists … brought The Hacker here, whether directly, or indirectly, through your actions, Xeets, attitudes, and glorifications of hatred, drugs, violence, and death.”
These arbitrary jailings were going to take place according to KatieBoutique, until Administration reached out to MoJ with instructions.
“I am not done jailing people on the left who brought The Hacker here, whether directly, or indirectly. Until the admins figure out what to do…and let me know what they want me to do, I will continue jailing people as I see fit.” The reaction had changed swiftly.
“Nope. Wasn’t that. I don’t care if you’re trying to rage bait, trying to blame other users on the site when this is very clearly a failing of Chris/SAN and admin isn’t productive and sure as shit won’t get you your money back,” wrote user Katrynah.
“Come on, I don't think they brough the hacker, this jailing is completely unjustified and undeserved ... People will just start deleting their accounts and the game will not be fun anymore :(“ Wrote user Isolde.
Things escalated from there. Minister of Justice KatieBoutique then jailed Minister of Entertainment Tibby, claiming she was “on good terms with The Hacker,” going on to threaten her with indefinite jailing until the end of the term in May. Freethinkerland General KirstyD8 commented criticizing the jailing. “I think they need to be able to communicate with Chris and they can't do that in jail. Mostly Tibby.”
The Minister of Justice posted public accusations that the hack was done by the boyfriend of former PX bxdcherri. No evidence was provided, but bxdcherri was banned permanently by Administration soonafter.
Since then, Minister of Construction, coder Sachem, on April 23 responded to the hack claiming a full rollback would be performed, leaving users nervous about the progress they had made since Sunday. The Minister assured the citizenry they were hard at work determining the problem. Thankfully, since then, Sachem's next post was a full recovery plan, clarifying that the specific exploits available to exploit Ximboland would be repaired: " We take this extremely seriously, and we want to reassure you that these attack vectors have been fully identified and patched." It outlines what changes have been made and outlines the technical fixes involved.
This unnerving and controversial series of events, following shortly after the sitewide shock in response to threats of the publication of revenge porn, led to the publication of a series of protest items in the shops. The item’s publication led to several permanent bannings. More on this in the next issue of the Bimbo City Breaking.

A Beginner’s Guide to NVH Testing in India’s Automotive Industry
Tumblr media
In today’s fast-paced world of data analytics, staying relevant means knowing how to turn raw data into smart decisions—and fast. Sure, tools like Python, SQL, and Power BI are gaining popularity, but if there’s one tool that still stands strong in 2025, it’s Microsoft Excel.
Whether you’re just starting out or you’ve been crunching numbers for years, Excel for data analyst roles remains one of the most practical and in-demand skills. It strikes that perfect balance between simplicity and capability, making it the go-to for countless data tasks.
In this post, we’ll look at why Excel isn’t going anywhere, the most valuable Excel job skills right now, and how you can sharpen your expertise to keep up with the latest demands in data analytics.
The Modern-Day Data Analyst: More Than Just a Number Cruncher
Back in the day, data analysts were mostly behind the scenes—collecting numbers, making charts, and maybe sending the occasional report. Fast forward to 2025, and their role is far more central. Today’s analysts are storytellers, business advisors, and problem solvers.
Here’s what a typical day might include:
Pulling raw data from different platforms (think CRMs, ERPs, databases, web analytics tools)
Cleaning and organizing that data so it actually makes sense
Analyzing trends to help forecast what’s coming next
Creating reports and dashboards that communicate findings clearly
Presenting insights to decision-makers in a way that drives action
And you guessed it—Excel shows up in almost every one of these steps.
Why Excel Still Matters (a Lot)
Some might argue that Excel is “old-school,” but here’s the reality: it’s still everywhere. And for good reason.
1. It’s Familiar to Everyone
From finance teams to marketing departments, most professionals have at least a basic grasp of Excel. That makes collaboration easy—no need to explain a tool everyone’s already using.
2. Quick Results, No Coding Required
Need to filter a dataset or run a few calculations? You can do it in Excel in minutes. It’s great for ad-hoc analysis where speed matters and there’s no time to build complex code.
3. Plays Nice with Other Tools
Excel isn’t an island. It connects smoothly with SQL databases, Google Analytics, Power BI, and even Python. Power Query is especially useful when pulling in and reshaping data from different sources.
4. It’s on Every Work Computer
You don’t need to install anything or get IT involved. Excel is ready to go on pretty much every company laptop, which makes it incredibly convenient.
Top Excel Skills Every Data Analyst Needs in 2025
To really stand out, you’ll want to move past the basics. Employers today expect you to do more than just sum a column or build a pie chart. Here’s where to focus your energy:
1. Data Cleaning and Transformation
Use functions like CLEAN(), TRIM(), and Text to Columns to fix messy data.
Power Query is a game-changer—it lets you clean, merge, and reshape large datasets without writing a line of code.
2. Advanced Formulas
Learn how to use INDEX, MATCH, XLOOKUP, IFERROR, and dynamic arrays. These help you build smarter, more flexible spreadsheets.
Nesting formulas (formulas within formulas) is super helpful for building logic into your models.
3. PivotTables and PivotCharts
Still one of the fastest ways to analyze large data sets.
Great for grouping, summarizing, and drilling into data—all without writing any SQL.
4. Power Query and Power Pivot
These tools turn Excel into a mini-BI platform.
You can pull in data from multiple tables, define relationships, and use DAX for more advanced calculations.
5. Interactive Dashboards
Combine charts, slicers, and conditional formatting to build dashboards that update as data changes.
Form controls (like drop-downs or sliders) add a professional touch.
6. Automation with Macros and VBA
Automate tasks like data formatting, report generation, and file creation.
Even basic VBA scripts can save hours each week on repetitive tasks.
Real-World Excel Use Cases That Still Matter
Let’s get practical. Here’s how Excel is still making an impact across industries:
Sales & Marketing: Track campaign performance, customer engagement, and conversion rates—all in a single dashboard.
Finance: Build cash flow models, scenario forecasts, and budget reports that help CFOs make data-driven calls.
Healthcare: Monitor key performance indicators like patient wait times or readmission rates.
Logistics: Analyze delivery times, shipping costs, and supplier performance to streamline operations.
These aren’t theoretical use cases—they’re actual day-to-day tasks being done in Excel right now.
Excel vs. Other Tools
Let’s be real: no single tool does it all. Excel fits into a broader ecosystem of data tools. Here’s a quick breakdown:TaskBest ToolHow Excel ContributesQuick AnalysisExcelFast and easy to useDashboardsPower BI / TableauExcel dashboards are perfect for internal or lightweight reportsData CleaningSQL / Power QueryExcel connects and transforms with Power QueryBig DataPython / RUse Excel for summary views and visualizations of Python output
Excel’s strength lies in how easily it fits into your workflow—even when you’re working with more advanced tools.
How to Get Better at Excel in 2025
If you’re serious about leveling up, here’s how to grow your skills:
1. Take a Course That Focuses on Analytics
Pick one that emphasizes real business problems and gives you projects to work on. Case studies are gold.
2. Practice on Real Data
Websites like Kaggle, data.gov, or even your company’s historical data (with permission, of course) are great places to start.
3. Learn Keyboard Shortcuts
You’ll work faster and feel more confident. Start with common ones like Ctrl + Shift + L for filters or Alt + = for autosum.
4. Dive into Power Query and Power Pivot
Once you get the hang of them, you’ll wonder how you ever worked without them.
5. Build Mini Projects
Create dashboards or models that solve specific business problems—like tracking customer churn or sales performance. These can become portfolio pieces for your next job interview.
Conclusion
Excel isn’t going anywhere. It’s deeply woven into how businesses run, and in 2025, it’s still one of the best tools in a data analyst’s toolkit. It might not be as flashy as Python or as powerful as Tableau, but it gets the job done—and done well.
If you’re aiming to future-proof your career, investing in advanced Excel job skills is a smart move. From dashboards to data modeling, the possibilities are endless. And when paired with other tools, Excel helps you deliver even more value to your team.
So keep practicing, keep building, and remember—being great at Excel can set you apart in the data world.

Shortwave Radiogram, 17-22 January 2025 (program 385): Return of the slow Olivia modes
With poor reception in many locations in recent weeks, we will transmit two Olivia modes that often survive weak signals and/or interference: Olivia 64-2000 and Olivia 32-2000. The 2000 refers to the bandwidth in Hz, so make sure your receiver can accommodate these modes extending from 500 to 2500 Hz above or below the carrier frequency. The SSB and AM modes on most receivers should be adequate. Also, these Olivia modes work better if Fldigi's squelch (SQL) is off. You will notice that these Olivia modes are slow: about 24 wpm for Olivia 64-2000 and 48 wpm for Olivia 32-2000. Wishing you poor reception this week, so you can see how these Olivia modes cope with adversity. Reception was good, in most parts of the world, this past Wednesday at 1330-1400 UTC on 15770 kHz from WRMI Florida. Unfortunately, the WRMI transmitter went off the air shortly after 1330 UTC. Then it came back for the first MFSK64 image, the flags of Norway. Then it quit again for the rest of the half hour.   Hoping for better luck on 15770 this Wednesday. A video of last week's Shortwave Radiogram (program 385) is provided by Scott in Ontario (Wednesday 1330 UTC) -- but the WRMI transmitter was down for most of that half hour. However, H0b0_Radio  in Washington state has made available an IQ recording of the Monday 0800-0830 UTC broadcast. The audio archive is maintained by Mark in the UK. Analysis is provided by Roger in Germany. Here is the lineup for Shortwave Radiogram, program 385, 17-22 January 2025, in MFSK and Olivia modes as noted:  1:48  MFSK32: Program preview  3:09  Olivia 64-2000**: Arctic permafrost is sinking  7:50  Olivia 32-2000**: Arctic permafrost (continued) 10:27  MFSK64: Blue Origin's New Glenn rocket launches* 14:58  MFSK64: Images of the week* 28:12  MFSK32: Closing announcements * with image(s) ** Turn off Fldigi's squelch SQL for the Olivia modes Please send reception reports to [email protected] And visit http://swradiogram.net Twitter: @SWRadiogram or https://twitter.com/swradiogram (visit during the weekend to see listeners’ results) Facebook group: https://www.facebook.com/groups/567099476753304 Shortwave Radiogram Gateway Wiki: https://wiki.radioreference.com/index.php/Shortwave_Radiogram_Gateway
THE SHORTWAVE RADIOGRAM TRANSMISSION SCHEDULE IS IN THE IMAGE BELOW. IF THE SCHEDULE IS NOT VISIBLE FULL WIDTH, CLICK ON IT.
Tumblr media
Other Shortwave broadcast programs that include digital text and images include The Mighty KBC, Pop Shop Radio and Radio North Europe International (RNEI). Links to these fine broadcasts, with schedules, are posted here.
Because of solar activity, almost no one decoded all of the images of the 0330-0400 UTC show, 11 January 2025, on 9265 kHz from WINB Pennsylvania. But Walt, using an SDR on an island half way up the cost of British Columbia, had a good decode of all the images ...

Automatic image tagging with Gemini AI
I used multimodal generative AI to tag my archive of 2,500 unsorted images. It was surprisingly effective.
I’m a digital packrat. Disk space is cheap, so why not save everything? That goes double for things out on the internet, especially those on third party servers, where you can’t be sure they’ll live forever. One of the sites that hasn’t lasted is ffffound!, a pioneering image bookmarking website, which I was lucky enough to be a member of.
Back around 2013 I wrote a quick Ruby web scraper to download my images, and ever since I’ve wondered what to do with the 2,500 or so images. ffffound was deliberately minimal - you got only the URL of the site it was saved from and a page title - so organising them seemed daunting.
Tumblr media
A little preview- this is what got pulled out tagged "maps".
The power of AI compels you!
As time went on, I thought about using machine learning to write tags or descriptions, but the process back then involved setting up models, training them yourself, and it all seemed like a lot of work. It's a lot less work now. AI models are cheap (or at least, for the end user, subsidised) and easy to access via APIs, even for multimodal queries.
After some promising quick explorations, I decided to use Google’s Gemini API to try tagging the images, mainly because they already had my billing details in Google Cloud and enabling the service was really easy.
Prototyping and scripting
My usual prototyping flow is opening an iPython shell and going through tutorials; of course, there’s one for Gemini, so I skipped to “Generate text from image and text inputs”, replaced their example image with one of mine, tweaked the prompt - ending up with ‘Generate ten unique, one to three word long, tags for this image. Output them as comma separated, without any additional text’ - and was up and running.
With that working, I moved instead to writing a script. Using the code from the interactive session as a core, I wrapped it in some loops, added a little SQL to persist the tags alongside the images in an existing database, and set it off by passing in a list of files on the command line. (The last step meant I could go from running it on the six files matching images/00\*.jpg up to everything without tweaking the code.) Occasionally it hit rather baffling errors, which weren’t well explained in the tutorial - I’ll cover how I handled them in a follow up post.
You can see the resulting script on GitHub. Running it over the entire set of images took a little while - I think the processing time was a few seconds per image, so I did a few runs of maybe an hour each to get all of them - but it was definitely much quicker than tagging by hand. Were the tags any good, though?
Exploring the results
I coded up a nice web interface so I was able to surf around tags. Using that, I could see what the results were. On the whole? Between fine and great. For example, it turns out I really like maps, with 308 of the 2,580 or so images ending up with the tag ‘map’ which are almost all, if not actual maps, do at least look cartographic in some way.
The vast majority of the most common tags I ended up with were the same way - the tag was generally applicable to all of the images in some way, even if it wasn’t totally obvious at first why. However, it definitely wasn’t perfect. One mistake I noticed was this diagram of roads tagged “rail” - and yet, I can see how a human would have done the same.
Tumblr media
Another small criticism? There was a lack of consistency across tags. I can think of a few solutions, including resubmitting the images as a group, making the script batch images together, or adding the most common tags to the prompt so the model can re-use them. (This is probably also a good point to note it might also be interesting to compare results with other multimodal models.)
Tumblr media Tumblr media
Finally, there were some odd edge cases to do with colour. I can see why most of these images are tagged ‘red’, but why is the telephone box there? While there do turn out to be specks of red in the diagram at the bottom right, I’d also go with “black and white” myself over “black”, “white”, and “red” as distinct tags.
Tumblr media
Worth doing?
On the whole, though, I think this experiment was pretty much a success. Tagging the images cost around 25¢ (US) in API usage, took a lot less time than doing so manually, and nudged me into exploring and re-sharing the archive. If you have a similar library, I’d recommend giving this sort of approach a try.

Common Mistakes Students Make During a Data Analyst Course in Noida
Tumblr media
Becoming a data analyst is a great career choice today. Companies are hiring skilled data analysts to understand their data and make smart decisions. Many students join a data analyst course in Noida to start their journey in this field. But sometimes, students make mistakes during the course that can slow down their learning or reduce their chances of getting a good job.
At Uncodemy, we have helped hundreds of students become successful data analysts. Based on our experience, we have listed some common mistakes students make during a data analyst course and how to avoid them. Read carefully so that you can learn better and get the most from your training.
1. Not Practicing Enough
One of the biggest mistakes students make is not practicing what they learn. Data analysis is a skill that requires hands-on work. You can’t become good at it by only watching videos or reading notes.
What You Should Do:
After every class, try to practice the concepts you learned.
Use platforms like Kaggle to work on real datasets.
Practice using Excel, SQL, Python, and other tools regularly.
Set a goal to spend at least 1–2 hours every day on practice.
2. Skipping the Basics
Many students want to learn advanced things quickly. They ignore the basics of Excel, statistics, or programming. This can be a big problem later because all advanced topics are built on the basics.
What You Should Do:
Take your time to understand basic Excel functions like VLOOKUP, Pivot Tables, etc.
Learn basic statistics: mean, median, mode, standard deviation, etc.
Start with simple Python or SQL commands before jumping into machine learning or big data.
3. Not Asking Questions
Some students feel shy or afraid to ask questions during the class. But if you don’t clear your doubts, they will keep piling up and confuse you more.
What You Should Do:
Don’t be afraid to ask questions. Your trainer is there to help.
If you feel uncomfortable asking in front of others, ask one-on-one after the class.
Join discussion forums or WhatsApp groups created by your training institute.
4. Focusing Only on Theory
A common mistake is spending too much time on theory and not enough on real-world projects. Companies don’t hire data analysts for their theory knowledge. They want someone who can solve real problems.
What You Should Do:
Work on multiple data projects like sales analysis, customer behavior, or survey data.
Add these projects to your resume or portfolio.
Uncodemy offers project-based learning—make sure you take full advantage of it.
5. Ignoring Soft Skills
Some students think only technical skills are important for a data analyst. But communication, teamwork, and presentation skills are also very important.
What You Should Do:
Practice explaining your analysis in simple words.
Create PowerPoint presentations to show your project findings.
Learn how to talk about your projects in interviews or meetings.
6. Not Learning Data Visualization
Data analysts must present their findings using charts, graphs, and dashboards. Some students skip learning tools like Power BI or Tableau, thinking they are not necessary. This is a big mistake.
What You Should Do:
Learn how to use Power BI or Tableau to make dashboards.
Practice making clear and beautiful visualizations.
Always include visual output in your projects.
7. Not Understanding the Business Side
Data analysis is not just about numbers. You must understand what the data means for the business. Students who only focus on the technical side may not solve the real problem.
What You Should Do:
Learn about different business functions: marketing, sales, HR, finance, etc.
When you work on a dataset, ask yourself: What problem are we trying to solve?
Talk to mentors or trainers about how businesses use data to grow.
8. Not Updating Resume or LinkedIn
You may become skilled, but if you don’t show it properly on your resume or LinkedIn, recruiters won’t notice you.
What You Should Do:
Update your resume after completing each project or module.
Add all certifications and tools you’ve learned.
Share your learning and projects on LinkedIn to build your presence.
9. Not Preparing for Interviews Early
Some students wait till the end of the course to start preparing for interviews. This is a mistake. Interview preparation takes time.
What You Should Do:
Start practicing common interview questions from the second month of your course.
Take mock interviews offered by Uncodemy.
Learn how to explain your projects confidently.
10. Not Choosing the Right Institute
Another mistake is choosing a training center that does not provide quality training, support, or placement help. This can waste your time and money.
What You Should Do:
Choose a trusted institute like Uncodemy that offers:
Experienced trainers
Hands-on projects
Interview and resume support
Placement assistance
Flexible timings (weekend or weekday batches)
11. Not Managing Time Properly
Many students, especially working professionals or college students, find it hard to balance their studies with other responsibilities. This leads to missed classes and incomplete assignments.
What You Should Do:
Make a weekly schedule for learning and stick to it.
Attend all live sessions or watch recordings if you miss them.
Complete small goals every day instead of piling work on weekends.
12. Not Joining a Learning Community
Learning alone can be hard and boring. Many students lose motivation because they don’t stay connected with others.
What You Should Do:
Join a study group or class group at Uncodemy.
Participate in hackathons or challenges.
Help others—you’ll learn better too!
13. Thinking Certification is Enough
Some students believe that just getting a certificate will get them a job. This is not true. Certificates are useful, but companies care more about your actual skills and experience.
What You Should Do:
Focus on building real projects and understanding the tools deeply.
Make a strong portfolio.
Practice solving business problems using data.
14. Not Reviewing Mistakes
Everyone makes mistakes while learning. But some students don’t take the time to review them and learn from them.
What You Should Do:
After every assignment or test, check where you made mistakes.
Ask your trainer to explain the right solution.
Keep a notebook to write down your weak areas and improve on them.
15. Trying to Learn Everything at Once
Some students try to learn too many tools and topics at the same time. This leads to confusion and poor understanding.
What You Should Do:
Follow a structured learning path, like the one offered at Uncodemy.
Master one tool at a time—first Excel, then SQL, then Python, and so on.
Focus on quality, not quantity.
Final Thoughts
A career in data analytics can change your life—but only if you take your training seriously and avoid the mistakes many students make. At Uncodemy, we guide our students step-by-step so they can become skilled, confident, and job-ready.
Remember, learning data analysis is a journey. Stay consistent, be curious, and keep practicing. Avoid the mistakes shared above, and you’ll be well on your way to a successful future.
