||||
|
||||
You can find a list of supported models at [IBM watsonx.ai Documentation](https://dataplatform.cloud.ibm.com/docs/content/wsj/analyze-data/fm-models-embed.html?context=wx). The currently supported model names are:
|
||||
|
||||
- `ibm/slate-125m-english-rtrvr`
|
||||
- `ibm/slate-30m-english-rtrvr`

# Full-text search
|
||||
|
||||
LanceDB provides support for full-text search via Lance (before via [Tantivy](https://github.com/quickwit-oss/tantivy) (Python only)), allowing you to incorporate keyword-based search (based on BM25) in your retrieval solutions.
|
||||
|
||||
Currently, the Lance full text search is missing some features that are in the Tantivy full text search. This includes phrase queries, re-ranking, and customizing the tokenizer. Thus, in Python, Tantivy is still the default way to do full text search and many of the instructions below apply just to Tantivy-based indices.
|
||||
LanceDB provides support for full-text search via [Tantivy](https://github.com/quickwit-oss/tantivy) (currently Python only), allowing you to incorporate keyword-based search (based on BM25) in your retrieval solutions. Our goal is to push the FTS integration down to the Rust level in the future, so that it's available for Rust and JavaScript users as well.

To search an FTS index via keywords, LanceDB's `table.search` accepts a string as input:
|
||||
|
||||
const data = [
|

{ vector: [3.1, 4.1], text: "Frodo was a happy puppy" },
|
||||
{ vector: [5.9, 26.5], text: "There are several kittens playing" },

await tbl.createIndex("text", {

## Tokenization
|
||||
By default the text is tokenized by splitting on punctuation and whitespaces and then removing tokens that are longer than 40 chars. For more language specific tokenization then provide the argument tokenizer_name with the 2 letter language code followed by "_stem". So for english it would be "en_stem".

# Building Scalar Index
|
||||
|
||||
Similar to many SQL databases, LanceDB supports several types of Scalar indices to accelerate search
|
||||
over scalar columns.
|
||||
|
||||
- `BTREE`: The most common type is BTREE. This index is inspired by the btree data structure
|
||||
although only the first few layers of the btree are cached in memory.
|
||||
It will perform well on columns with a large number of unique values and few rows per value.
|
||||
- `BITMAP`: this index stores a bitmap for each unique value in the column.
|
||||
This index is useful for columns with a finite number of unique values and many rows per value.
|
||||
For example, columns that represent "categories", "labels", or "tags"
|
||||
- `LABEL_LIST`: a special index that is used to index list columns whose values have a finite set of possibilities.
|
||||
For example, a column that contains lists of tags (e.g. `["tag1", "tag2", "tag3"]`) can be indexed with a `LABEL_LIST` index.
|
||||
|
||||
| Data Type | Filter | Index Type |
|
||||
| --------------------------------------------------------------- | ----------------------------------------- | ------------ |
|
||||
| Numeric, String, Temporal | `<`, `=`, `>`, `in`, `between`, `is null` | `BTREE` |
|
||||
| Boolean, numbers or strings with fewer than 1,000 unique values | `<`, `=`, `>`, `in`, `between`, `is null` | `BITMAP` |
|
||||
| List of low cardinality of numbers or strings | `array_has_any`, `array_has_all` | `LABEL_LIST` |

!!! tip "Automatic cleanup for failed writes"
|

|

LanceDB uses [multi-part uploads](https://docs.aws.amazon.com/AmazonS3/latest/userguide/mpuoverview.html) when writing data to S3 in order to maximize write speed. LanceDB will abort these uploads when it shuts down gracefully, such as when cancelled by keyboard interrupt. However, in the rare case that LanceDB crashes, it is possible that some data will be left lingering in your account. To cleanup this data, we recommend (as AWS themselves do) that you setup a lifecycle rule to delete in-progress uploads after 7 days. See the AWS guide:

#### DynamoDB Commit Store for concurrent writes
|
||||
|
||||
By default, S3 does not support concurrent writes. Having two or more processes
|
||||
writing to the same table at the same time can lead to data corruption. This is
|
||||
because S3, unlike other object stores, does not have any atomic put or copy
|
||||
operation.
|
||||
|
||||
To enable concurrent writes, you can configure LanceDB to use a DynamoDB table
|
||||
as a commit store. This table will be used to coordinate writes between
|
||||
different processes. To enable this feature, you must modify your connection
|
||||
URI to use the `s3+ddb` scheme and add a query parameter `ddbTableName` with the
|
||||
name of the table to use.

|

|

The DynamoDB table must be created with the following schema:

- Hash key: `base_uri` (string)

|

Another way to improve retriever performance is to fine-tune the embedding model itself. Fine-tuning the embedding model can help in learning better representations for the documents and queries in the dataset. This can be particularly useful when the dataset is very different from the pre-trained data used to train the embedding model.
|
||||
|
||||
We'll use the same dataset as in the previous sections. Start off by splitting the dataset into training and validation sets:
|
||||
```python
|
||||
from sklearn.model_selection import train_test_split
|
||||
|
||||
train_df, validation_df = train_test_split("data_qa.csv", test_size=0.2, random_state=42)
|
||||
|
||||
train_df.to_csv("data_train.csv", index=False)
|
||||
validation_df.to_csv("data_val.csv", index=False)
|
||||
```
|
||||
|
||||
You can use any tuning API to fine-tune embedding models. In this example, we'll utilise Llama-index as it also comes with utilities for synthetic data generation and training the model.
|
||||
|
||||
|
||||
Then parse the dataset as llama-index text nodes and generate synthetic QA pairs from each node.
|
||||
```python
|
||||
from llama_index.core.node_parser import SentenceSplitter
|
||||
from llama_index.readers.file import PagedCSVReader
|
||||
from llama_index.finetuning import generate_qa_embedding_pairs
|
||||
from llama_index.core.evaluation import EmbeddingQAFinetuneDataset
|
||||
|
||||
def load_corpus(file):
|
||||
loader = PagedCSVReader(encoding="utf-8")
|
||||
docs = loader.load_data(file=Path(file))
|
||||
|
||||
parser = SentenceSplitter()
|
||||
nodes = parser.get_nodes_from_documents(docs)
|
||||
|
||||
return nodes
|
||||
|
||||
from llama_index.llms.openai import OpenAI
|
||||
|
||||
|
||||
train_dataset = generate_qa_embedding_pairs(
|
||||
llm=OpenAI(model="gpt-3.5-turbo"), nodes=train_nodes, verbose=False
|
||||
)
|
||||
val_dataset = generate_qa_embedding_pairs(
|
||||
llm=OpenAI(model="gpt-3.5-turbo"), nodes=val_nodes, verbose=False
|
||||
)
|
||||
```
|
||||
|
||||
Now we'll use `SentenceTransformersFinetuneEngine` engine to fine-tune the model. You can also use `sentence-transformers` or `transformers` library to fine-tune the model.
|
||||
|
||||
```python
|
||||
from llama_index.finetuning import SentenceTransformersFinetuneEngine
|
||||
|
||||
finetune_engine = SentenceTransformersFinetuneEngine(
|
||||
train_dataset,
|
||||
model_id="BAAI/bge-small-en-v1.5",
|
||||
model_output_path="tuned_model",
|
||||
val_dataset=val_dataset,
|
||||
)
|
||||
finetune_engine.finetune()
|
||||
embed_model = finetune_engine.get_finetuned_model()
|
||||
```
|
||||
This saves the fine tuned embedding model in `tuned_model` folder. This al
|
||||
|
||||
# Evaluation results
|
||||
In order to eval the retriever, you can either use this model to ingest the data into LanceDB directly or llama-index's LanceDB integration to create a `VectorStoreIndex` and use it as a retriever.
|
||||
On performing the same hit-rate evaluation as before, we see a significant improvement in the hit-rate across all query types.

||||

# dlt
|
||||
|
||||
[dlt](https://dlthub.com/docs/intro) is an open-source library that you can add to your Python scripts to load data from various and often messy data sources into well-structured, live datasets. dlt's [integration with LanceDB](https://dlthub.com/docs/dlt-ecosystem/destinations/lancedb) lets you ingest data from any source (databases, APIs, CSVs, dataframes, JSONs, and more) into LanceDB with a few lines of simple python code. The integration enables automatic normalization of nested data, schema inference, incremental loading and embedding the data. dlt also has integrations with several other tools like dbt, airflow, dagster etc. that can be inserted into your LanceDB workflow.
|
||||
|
||||
## How to ingest data into LanceDB
|
||||
|
||||
In this example, we will be fetching movie information from the [Open Movie Database (OMDb) API](https://www.omdbapi.com/) and loading it into a local LanceDB instance. To implement it, you will need an API key for the OMDb API (which can be created freely [here](https://www.omdbapi.com/apikey.aspx)).
|
||||
|
||||
1. **Install `dlt` with LanceDB extras:**
|
||||
```sh
|
||||
pip install dlt[lancedb]
|
||||
```
|
||||
|
||||
2. **Inside an empty directory, initialize a `dlt` project with:**
|
||||
```sh
|
||||
dlt init rest_api lancedb
|
||||
```
|
||||
This will add all the files necessary to create a `dlt` pipeline that can ingest data from any REST API (ex: OMDb API) and load into LanceDB.
|
||||
```text
|
||||
├── .dlt
|
||||
│ ├── config.toml
|
||||
│ └── secrets.toml
|
||||
├── rest_api
|
||||
├── rest_api_pipeline.py
|
||||
└── requirements.txt
|
||||
```
|
||||
|
||||
dlt has a list of pre-built [sources](https://dlthub.com/docs/dlt-ecosystem/verified-sources/) like [SQL databases](https://dlthub.com/docs/dlt-ecosystem/verified-sources/sql_database), [REST APIs](https://dlthub.com/docs/dlt-ecosystem/verified-sources/rest_api), [Google Sheets](https://dlthub.com/docs/dlt-ecosystem/verified-sources/google_sheets), [Notion](https://dlthub.com/docs/dlt-ecosystem/verified-sources/notion) etc., that can be used out-of-the-box by running `dlt init <source_name> lancedb`. Since dlt is a python library, it is also very easy to modify these pre-built sources or to write your own custom source from scratch.
|
||||
|
||||
|
||||
3. **Specify necessary credentials and/or embedding model details:**
|
||||
|
||||
In order to fetch data from the OMDb API, you will need to pass a valid API key into your pipeline. Depending on whether you're using LanceDB OSS or LanceDB cloud, you also may need to provide the necessary credentials to connect to the LanceDB instance. These can be pasted inside `.dlt/sercrets.toml`.
|
||||
|
||||
dlt's LanceDB integration also allows you to automatically embed the data during ingestion. Depending on the embedding model chosen, you may need to paste the necessary credentials inside `.dlt/sercrets.toml`:
|
||||
```toml
|
||||
[sources.rest_api]
|
||||
api_key = "api_key" # Enter the API key for the OMDb API
|
||||
|
||||
[destination.lancedb]
|
||||
embedding_model_provider = "sentence-transformers"
|
||||
embedding_model = "all-MiniLM-L6-v2"
|
||||
[destination.lancedb.credentials]
|
||||
uri = ".lancedb"
|
||||
api_key = "api_key" # API key to connect to LanceDB Cloud. Leave out if you are using LanceDB OSS.
|
||||
embedding_model_provider_api_key = "embedding_model_provider_api_key" # Not needed for providers that don't need authentication (ollama, sentence-transformers).
|
||||
```
|
||||
See [here](https://dlthub.com/docs/dlt-ecosystem/destinations/lancedb#configure-the-destination) for more information and for a list of available models and model providers.
|
||||
|
||||
|
||||
4. **Write the pipeline code inside `rest_api_pipeline.py`:**
|
||||
|
||||
The following code shows how you can configure dlt's REST API source to connect to the [OMDb API](https://www.omdbapi.com/), fetch all movies with the word "godzilla" in the title, and load it into a LanceDB table. The REST API source allows you to pull data from any API with minimal code, to learn more read the [dlt docs](https://dlthub.com/docs/dlt-ecosystem/verified-sources/rest_api).

|

```python
|

|
||||
import dlt
|
||||
from rest_api import rest_api_source
|
||||
|

}
|

||||
# Create a pipeline object
|
||||
pipeline = dlt.pipeline(
|
||||
pipeline_name='movies_pipeline',
|
||||
destination='lancedb', # this tells dlt to load the data into LanceDB
|
||||
dataset_name='movies_data_pipeline',
|

|
||||
|
||||
# Run the pipeline
|
||||
load_info = pipeline.run(movies_source)
|
||||
|
||||
# pretty print the information on data that was loaded
|
||||
print(load_info)
|
||||
```
|
||||
|
||||
The script above will ingest the data into LanceDB as it is, i.e. without creating any embeddings. If we want to embed one of the fields (for example, `"Title"` that contains the movie titles), then we will use dlt's `lancedb_adapter` and modify the script as follows:
|
||||
|
||||
- Add the following import statement:
|
||||
```python
|
||||
from dlt.destinations.adapters import lancedb_adapter
|
||||
```
|
||||
- Modify the pipeline run like this:
|
||||
```python
|
||||
load_info = pipeline.run(
|
||||
lancedb_adapter(
|
||||
movies_source,
|
||||
embed="Title",
|
||||
)
|
||||
)
|
||||
```
|
||||
This will use the embedding model specified inside `.dlt/secrets.toml` to embed the field `"Title"`.
|
||||
|
||||
5. **Install necessary dependencies:**
|
||||
```sh
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
Note: You may need to install the dependencies for your embedding models separately.
|
||||
```sh
|
||||
pip install sentence-transformers
|
||||
```
|
||||
|
||||
6. **Run the pipeline:**
|
||||
Finally, running the following command will ingest the data into your LanceDB instance.
|
||||
```sh
|
||||
python custom_source.py
|
||||
```

To manually lint your code you can run:
|
||||
LanceDb uses eslint for linting. VSCode does not need any plugins to use eslint. However, it
|
||||
may need some additional configuration. Make sure that eslint.experimental.useFlatConfig is
|
||||
set to true. Also, if your vscode root folder is the repo root then you will need to set
|
||||
the eslint.workingDirectories to ["nodejs"]. To manually lint your code you can run:
|
||||
|
||||
```sh
|
||||
npm run lint
|
||||
```
|
||||
|
||||
to automatically fix all fixable issues:
|
||||
LanceDb uses prettier for formatting. If you are using VSCode you will need to install the
|
||||
"Prettier - Code formatter" extension. You should then configure it to be the default formatter
|
||||
for typescript and you should enable format on save. To manually check your code's format you
|
||||
can run:
|
||||
|
||||
```sh
|
||||
npm run lint-fix
|
||||
npm run chkformat
|
||||
```
|
||||
|
||||
If you do not have your workspace root set to the `nodejs` directory, unfortunately the extension will not work. You can still run the linting and formatting commands manually.
|
||||
If you need to manually format your code you can run:
|
||||
|
||||
```sh
|
||||
npx prettier --write .
|
||||
```

Checks out a specific version of the table _This is an in-place operation._
|
||||
### checkout
|
||||
|
||||
This allows viewing previous versions of the table. If you wish to
|
||||
keep writing to the dataset starting from an old version, then use
|
||||
the `restore` function.
|
||||
▸ **checkout**(`version`): `Promise`\<`void`\>
|
||||
|
||||
Calling this method will set the table into time-travel mode. If you
|
||||
wish to return to standard mode, call `checkoutLatest`.
|
||||
Checks out a specific version of the Table
|
||||
|
||||
Any read operation on the table will now access the data at the checked out version.
|
||||
As a consequence, calling this method will disable any read consistency interval
|
||||
that was previously set.
|
||||
|
||||
This is a read-only operation that turns the table into a sort of "view"
|
||||
or "detached head". Other table instances will not be affected. To make the change
|
||||
permanent you can use the `[Self::restore]` method.
|
||||
|
||||
Any operation that modifies the table will fail while the table is in a checked
|
||||
out state.
|
||||
|
||||
To return the table to a normal state use `[Self::checkout_latest]`
|
||||
|

Optimize the on-disk data and indices for better performance.
|

Modeled after ``VACUUM`` in PostgreSQL.
|
||||
|
||||
Optimization covers three operations:
|
||||
|
||||
- Compaction: Merges small files into larger ones
|
||||
- Prune: Removes old versions of the dataset
|
||||
- Index: Optimizes the indices, adding new data to existing indices
|
||||
|
||||
Experimental API
|
||||
----------------
|
||||
|
||||
The optimization process is undergoing active development and may change.
|
||||
Our goal with these changes is to improve the performance of optimization and
|
||||
reduce the complexity.
|
||||
|
||||
That being said, it is essential today to run optimize if you want the best
|
||||
performance. It should be stable and safe to use in production, but it our
|
||||
hope that the API may be simplified (or not even need to be called) in the
|
||||
future.
|
||||
|
||||
The frequency an application shoudl call optimize is based on the frequency of
|
||||
data modifications. If data is frequently added, deleted, or updated then
|
||||
optimize should be run frequently. A good rule of thumb is to run optimize if
|
||||
you have added or modified 100,000 or more records or run more than 20 data
|
||||
modification operations.

## TypeScript/JavaScript

For JS/TS users, we offer a brand new SDK [@lancedb/lancedb](https://www.npmjs.com/package/@lancedb/lancedb)
|
||||
|
||||
We tried to keep the API as similar as possible to the previous version, but there are a few small changes. Here are the most important ones:
|
||||
|
||||
### Creating Tables
|
||||
|
||||
[CreateTableOptions.writeOptions.writeMode](./javascript/interfaces/WriteOptions.md#writemode) has been replaced with [CreateTableOptions.mode](./js/interfaces/CreateTableOptions.md#mode)
|
||||
|
||||
=== "vectordb (deprecated)"
|
||||
|
||||
```ts
|
||||
db.createTable(tableName, data, { writeMode: lancedb.WriteMode.Overwrite });
|
||||
```
|
||||
|
||||
=== "@lancedb/lancedb"
|
||||

||||
```ts
|
||||
db.createTable(tableName, data, { mode: "overwrite" })
|

```
|

|
||||
### Changes to Table APIs
|
||||
|
||||
Previously `Table.schema` was a property. Now it is an async method.
|
||||
|
||||
#### Creating Indices
|
||||
|
||||
The `Table.createIndex` method is now used for creating both vector indices
|
||||
and scalar indices. It currently requires a column name to be specified (the
|
||||
column to index). Vector index defaults are now smarter and scale better with
|
||||
the size of the data.
|
||||
|
||||
=== "vectordb (deprecated)"
|
||||
|
||||
```ts
|
||||
await tbl.createIndex({
|
||||
column: "vector", // default
|
||||
type: "ivf_pq",
|
||||
num_partitions: 2,
|
||||
num_sub_vectors: 2,
|
||||
});
|
||||
```
|
||||
|
||||
=== "@lancedb/lancedb"
|
||||
|
||||
```ts
|
||||
await table.createIndex("vector", {
|
||||
config: lancedb.Index.ivfPq({
|
||||
numPartitions: 2,
|
||||
numSubVectors: 2,
|
||||
}),
|
||||
});
|
||||
```
|
||||
|
||||
### Embedding Functions
|
||||
|
||||
The embedding API has been completely reworked, and it now more closely resembles the Python API, including the new [embedding registry](./js/classes/embedding.EmbeddingFunctionRegistry.md)
|
||||
|
||||
=== "vectordb (deprecated)"
|
||||
|
||||
```ts
|
||||
|
||||
const embeddingFunction = new lancedb.OpenAIEmbeddingFunction('text', API_KEY)
|
||||
const data = [
|
||||
{ id: 1, text: 'Black T-Shirt', price: 10 },
|
||||
{ id: 2, text: 'Leather Jacket', price: 50 }
|
||||
]
|
||||
const table = await db.createTable('vectors', data, embeddingFunction)
|
||||
```
|
||||
|
||||
=== "@lancedb/lancedb"
|
||||
|
||||
```ts
|
||||
import * as lancedb from "@lancedb/lancedb";
|
||||
import * as arrow from "apache-arrow";
|
||||
import { LanceSchema, getRegistry } from "@lancedb/lancedb/embedding";
|
||||
|
||||
const func = getRegistry().get("openai").create({apiKey: API_KEY});
|
||||
|
||||
const data = [
|
||||
{ id: 1, text: 'Black T-Shirt', price: 10 },
|
||||
{ id: 2, text: 'Leather Jacket', price: 50 }
|
||||
]
|
||||
|
||||
const table = await db.createTable('vectors', data, {
|
||||
embeddingFunction: {
|
||||
sourceColumn: "text",
|
||||
function: func,
|
||||
}
|
||||
})
|
||||
|
||||
```
|
||||
|
||||
You can also use a schema driven approach, which parallels the Pydantic integration in our Python SDK:
|
||||
|
||||
```ts
|
||||
const func = getRegistry().get("openai").create({apiKey: API_KEY});
|
||||
|
||||
const data = [
|
||||
{ id: 1, text: 'Black T-Shirt', price: 10 },
|
||||
{ id: 2, text: 'Leather Jacket', price: 50 }
|
||||
]
|
||||
const schema = LanceSchema({
|
||||
id: new arrow.Int32(),
|
||||
text: func.sourceField(new arrow.Utf8()),
|
||||
price: new arrow.Float64(),
|
||||
vector: func.vectorField()
|
||||
})
|
||||
|
||||
const table = await db.createTable('vectors', data, {schema})

"What I Worked On\n",

"\n",
|

"February 2021\n",
|
||||
"\n",
|
||||
"Before college the two main things I worked on, outside of school, were writing and programming. I didn't write essays. I wrote what beginning writers were supposed to write then, and probably still are: short stories. My stories were awful. They had hardly any plot, just characters with strong feelings, which I imagined made them deep.\n",
|
||||
"\n",
|
||||
"The first programs I tried writing were on the IBM 1401 that our school district used for what was then called \"data processing.\" This was in 9th grade, so I was 13 or 14. The school district's 1401 happened to be in the basement of our junior high school, and my friend Rich Draves and I got permission to use it. It was like a mini Bond villain's lair down there, with all these alien-looking machines — CPU, disk drives, printer, card reader — sitting up on a raised floor under bright fluorescent lights.\n",
|
||||
"\n",
|
||||
"The language we used was an early version of Fortran. You had to type programs on punch cards, then stack them in the card reader and press a button to load the program into memory and run it. The result would ordinarily be to print something on the spectacularly loud printer.\n",
|
||||
"\n",
|
||||
"I was puzzled by the 1401. I couldn't figure out what to do with it. And in retrospect there's not much I could have done with it. The only form of input to programs was data stored on punched cards, and I didn't have any data stored on punched cards. The only other option was to do things that didn't rely on any input, like calculate approximations of pi, but I didn't know enough math to do anything interesting of that type. So I'm not surprised I can't remember any programs I wrote, because they can't have done much. My clearest memory is of the moment I learned it was possible for programs not to terminate, when one of mine didn't. On a machine without time-sharing, this was a social as well as a technical error, as the data center manager's expression made clear.\n",
|
||||
"\n",
|
||||
"With microcomputers, everything changed. Now you could have a computer sitting right in front of you, on a desk, that could respond to your keystrokes as it was running instead of just churning through a stack of punch cards and then stopping. [1]\n",
|
||||
"\n",
|
||||
"The first of my friends to get a microcomputer built it himself. It was sold as a kit by Heathkit. I remember vividly how impressed and envious I felt watching him sitting in front of it, typing programs right into the computer.\n",
|
||||
"\n",
|
||||
"Computers were expensive in those days and it took me years of nagging before I convinced my father to buy one, a TRS-80, in about 1980. The gold standard then was the Apple II, but a TRS-80 was good enough. This was when I really started programming. I wrote simple games, a program to predict how high my model rockets would fly, and a word processor that my father used to write at least one book. There was only room in memory for about 2 pages of text, so he'd write 2 pages at a time and then print them out, but it was a lot better than a typewriter.\n",
|
||||
"\n",
|
||||
"Though I liked programming, I didn't plan to study it in college. In college I was going to study philosophy, which sounded much more powerful. It seemed, to my naive high school self, to be the study of the ultimate truths, compared to which the things studied in other fields would be mere domain knowledge. What I discovered when I got to college was that the other fields took up so much of the space of ideas that there wasn't much left for these supposed ultimate truths. All that seemed left for philosophy were edge cases that people in other fields felt could safely be ignored.\n",
|
||||
"\n",
|
||||
"I couldn't have put this into words when I was 18. All I knew at the time was that I kept taking philosophy courses and they kept being boring. So I decided to switch to AI.\n",
|
||||
"\n",
|
||||
"AI was in the air in the mid 1980s, but there were two things especially that made me want to work on it: a novel by Heinlein called The Moon is a Harsh Mistress, which featured an intelligent computer called Mike, and a PBS documentary that showed Terry Winograd using SHRDLU. I haven't tried rereading The Moon is a Harsh Mistress, so I don't know how well it has aged, but when I read it I was drawn entirely into its world.\n",
